105-547: The Gladiator nameplate was revived on a midsize pickup truck based on the fourth-generation Jeep Wrangler (JL) . It was unveiled at the Los Angeles Auto Show on November 28, 2018. The original Jeep pickup truck was the Willys-Overland one-ton 4x4 also available in platform stake, chassis cab, or bare chassis versions manufactured from 1947 until 1965. Several sizes of Forward Control pickup trucks with

210-409: A 3 + 1 ⁄ 2 -inch (88.9 mm) bore, 287 cu in (4.7 L) 3 + 3 ⁄ 4 inches (95.3 mm), and the 327 cu in (5.4 L) a 4-inch (101.6 mm) bore. A number indicating the bore size is cast on the top of the engine block's flywheel housing immediately behind the right bank cylinder head . The block features a deep skirt where the casting extends below

315-538: A power take-off for numerous accessories that included snow plows and push plates. In early 1963, Willys Motors changed its name to Kaiser Jeep Corporation . During 1965 the 327 cu in (5.4 L) AMC V8 engine became available. It produced 250 hp (186 kW; 253 PS) and 340 pound force-feet (461 N⋅m) of torque at 2600 rpm. The standard Tornado engine was replaced by American Motors' 232 cu in (3.8 L) OHV inline six . In 1967 all (RWD) two-wheel drive versions, except for

420-472: A 1,500-pound (680 kg) payload . A "midgate" made the concept Gladiator truck closer to an imitation of the Chevrolet Avalanche , "than an attempt to revive its namesake's glory." The 2005 Gladiator Concept was also a preview of the all-new 2007 Jeep Wrangler (JK) and Jeep Wrangler (JK) Unlimited. These featured nearly identical exterior and interior styling to the production model of

525-783: A 17 kWh (61 MJ) lithium-ion battery pack that gives it an EPA-estimated range of 21 miles (34 km) and an EPA-rated 49 MPGe . It is available in China, Europe, and the United States. For 2022, the 4xe became the only variant of the Wrangler offered in Europe. A V8 powered version of the Rubicon trim level debuted for the 2021 model year. This trim goes by Rubicon 392 and produces 470 hp (350 kW; 477 PS) horsepower and 470 lb⋅ft (637 N⋅m) of torque from

630-457: A 2.8-liter, 4-cylinder common-rail turbo diesel engine that provides 165 hp (123 kW; 167 PS) and 295 lb⋅ft (400 N⋅m) of torque. The truck has a 6-speed manual transmission . Ground clearance is 13.7 in (348 mm), with a break-over angle of 23.2°, an approach angle of 47.6° and departure angle of 38.0°. Front and rear tires are 34 in (864 mm) and are mounted on 18x8-inch wheels. The Jeep Gladiator has

735-646: A Ford "Flareside" or Chevrolet "Stepside"), and flat stake bed, with up to 8,600 lb (3,901 kg) G.V.W. and almost two-ton payload capacity. A new overhead cam Jeep Tornado engine 230 cu in (3.8 L) straight-six producing 140 hp (104 kW; 142 PS) was standard. It was the first production overhead cam engine in an American light truck or SUV and one of the first OHC engines offered by an American manufacturer. Further innovations for four-wheel-drive pickups included optional automatic transmission (an industry first), as well as power brakes, power steering, and just like early post-war Jeeps

840-664: A Jeep Scrambler pickup was shown in 2003 at the North American Dealers Association, but was pulled after a few hours. According to Motor Trend , there might be a "production Jeep pickup truck in the works". In late-2004 a new Jeep Gladiator concept was introduced. While not officially intended to be sold, it was used as a demonstration "that a Jeep pickup was in the dark recesses of DaimlerChrysler's brain trust". The Gladiator concept features an open-air canvas roof, fold-down windshield , removable doors, and an expandable truck bed. The Gladiator has

945-524: A Rebel (or later Classic) through 1964. For 1965 and 1966 the 287 and 327 were both available in the Classic and Ambassador. The AMC 327 was sold to Kaiser-Jeep from 1965 until 1967 for use in the Jeep Wagoneer SUV and Gladiator pick-up truck. Jeep named it the "Vigilante" V8. Two-barrel carburation was standard on these Jeep models, but a four-barrel high-compression version was available in

1050-513: A V8 engine in their vehicles that was designed, built or supplied by any other manufacturer. The first design was produced from 1956 through 1967. An Electrojector version was to be the first commercial electronic fuel injected (EFI) production engine for the 1957 model year. The second design was introduced in 1966 and became available in several displacements over the years as well as in high-performance and racing versions. In 1987, Chrysler Corporation acquired AMC and continued manufacturing

1155-541: A V8 version of the Rambler six and included associated upgrades such as stronger front springs and rear axle. The Rebel model name also differentiated it from the standard six-cylinder Rambler. The big Nash and Hudson cars were also dropped after 1957, replaced by the 1958 "Ambassador by Rambler" — a stretched Rebel with the 327 V8 instead of the 250. The 327 was exclusive to the Ambassador line and could not be ordered in

1260-566: A cab-over design were manufactured by Kaiser from 1957 through 1966. The first Gladiator pickup trucks were developed by Kaiser in the early 1960s and were continued with improvements through the 1970s by American Motors Corporation (AMC) and also in international markets. The Gladiator-based Jeep SJ full-sized pickup truck models, as well as the compact XJ-based Jeep Comanche pickups, were discontinued by Chrysler after acquiring AMC. Chrysler claimed capacity limitations to manufacture new Jeep pickup models. However, after over 25 years, Jeep reentered

1365-552: A full bench seat in the cab. At the 2016 Jeep Safari in Moab, Utah, Jeep revealed seven new concepts including a Crew Chief 715 pickup with four-doors and a 5-foot cargo bed. The design was inspired by the Kaiser Jeep M715 military vehicle from the late 1960s that was based on the regular civilian production Jeep Gladiator pickup. The Jeep Crew Chief concept rides on 20-inch beadlock wheels, and 40-inch military tires, but

1470-430: A fully integrated and federally mandated rear-view backup camera as standard equipment. The camera is mounted to the spare tire and can be disconnected when the tire is removed. Rear passengers now get a 115 V AC household-style power outlet, as well as rear USB charging ports on Wrangler Unlimited models. The interior design was inspired by the 1954–1983 Jeep CJ-5 and 1987–1995 Wrangler (YJ) models. The majority of

1575-628: A heated leather-wrapped steering wheel. Rubicon models equipped with the Black interior include exclusive red stitching on the seats and steering wheel, while Moab models feature contrasting gray stitching, and the 392 has bronze stitching. Black Katzkin leather-trimmed seating surfaces are available as a Mopar dealer-installed accessory option for all trim levels, in either standard or perforated trim. Cloth-equipped models include painted dashboard surface (Silver-painted on Sport, Sport "S", and Sahara models, and Red-painted on some Rubicon models, dependent on

1680-438: A lower-priced Willys model for 2023, gains a new base-model Sport "S" trim for 2024. Inside, all Wrangler models now receive a standard U Connect 5 twelve-inch infotainment system with wired and wireless Apple CarPlay and Android Auto smartphone integration and Jeep Connect with 4G LTE Wi-Fi connectivity, with optional GPS navigation, a built-in off-road trail guide, HD Radio , SiriusXM Satellite Radio with 360L, and

1785-498: A marine engines marketed as "Fireball" by the Gray Marine Motor Company starting in 1958. Gray started offering the 250 in 1959. The 250 was offered in 135, 160, 170, 175, 178, and 185 horsepower versions. The 327 was made in 188, 215, 220, 225, and 238 horsepower levels. Gray used the 250 through 1966. The 327 was used as a 220 hp model in 1967, the last year an AMC V8 was used. The new-generation AMC V8

1890-546: A mid-cycle refresh. On the exterior, all models receive new tire and wheel combinations, as well as the front grille that originally debuted on the 2023 Rubicon 20th Anniversary Edition (the Sport and the Sport "S" trims retain the original front grille). Both 2-door and 4-door Unlimited models receive a new Rubicon "X" trim, which contains all of the previously-optional equipment on the Rubicon (the standard Rubicon trim no longer offers these features). The Unlimited 4xe, which received

1995-435: A more powerful 258 cu in (4.2 L) six-cylinder engine, and heavier axle tubes, while power front disc brakes became standard equipment and the considerably greater gross vehicle weight rating (GWV) capacity J-20s included AMC's 360 cu in (5.9 L) V8 engine. The 401 cu in (6.6 L) engine was optional, as well as full-time Quadra-Trac and both automatic and manual transmissions. 1983 saw

2100-538: A nine-speaker Alpine premium sound system with an amplifier and a weatherproof subwoofer . The center stack is redesigned to accept the larger touchscreen , which removes the genuine metal dashboard trim, as well as replaces the previous round air vents with horizontal rectangular units. Most models receive the premium Sun Rider soft top roof as standard equipment, while other models receive a standard color-keyed Freedom Top three-piece hard top roof and color-keyed front and rear fender flares. All Wrangler models equipped with

2205-494: A pioneering electronic fuel injected (EFI) "Electrojector" in that larger size beginning in 1957. American Motors' president, George W. Mason , had negotiated a verbal agreement with Packard that the two companies would supply parts for each other when practical. This was a prelude to a possible merger of the two companies at a later date, but that never occurred. With the industry-wide acceptance of V8 engine designs after World War II , AMC started buying Packard V8s in 1954 for

2310-413: A solid front axle on the 4WD half-ton Gladiator trucks. It was a simple IFS design with a Dana 44 center section, that proved troublesome, did not sell well, and the option was deleted in 1965. Gladiator trucks were also available as cab and chassis, wrecker, stake bed, and with chassis -mounted campers with extended wheelbases. The load bed options were Townside, Thriftside (a conventional bed, similar to

2415-496: A three-speed automatic or a floor-mounted four-speed manual transmission and made the car "suitable for the Stoplight Grand Prix." The 343 cu in (5.6 L) has a bore and stroke of 4.08 in × 3.28 in (103.6 mm × 83.3 mm). The basic 343/2V produced 235 hp (175 kW; 238 PS) and was built from 1967 through 1969. Output for the optional four-barrel carburetor version

2520-540: A traditional shifter. The engine performance is unchanged from the previous model at 285 hp (213 kW; 289 PS) and 260 lb⋅ft (353 N⋅m). This is only offered on Wrangler models sold in North America, Middle East, Australia, and New Zealand. The new engine features an optional mild hybrid system branded as eTorque for improved fuel economy and off-road performance. A 2.0 L turbocharged four-cylinder ( Inline-4 ) FCA Global Medium Engine

2625-407: A two-barrel carburetor and all high-compression models received a four-barrel carb. The low compression of 8.7:1 and high of 9.7:1 was affected by a difference in pistons. The AMC 327 was also offered as a marine engine as the "Fireball" by Gray Marine Motor Company . The AMC 327 was to be the first commercial electronic fuel injected (EFI) "Electrojector" production engine. Press reports about

2730-408: A two-barrel or four-barrel carburetor, respectively. It was built from the mid-1966 model year through the 1969 model year. It has a bore and stroke of 3.75 in × 3.28 in (95.3 mm × 83.3 mm). Only 623 cars were built in 1966 with the 290 engine. These engines were available in special Rambler American two-door Rogue models. The newly powered Rogue was available with either

2835-494: Is 280 hp (209 kW; 284 PS) and produces 365 lb⋅ft (495 N⋅m) of torque (gross). This version has a 10.2:1 compression ratio. The 390 cu in (6.4 L) AMX engine had a bore and stroke of 4.165 in × 3.574 in (105.8 mm × 90.8 mm). It received heavier main bearing support webbing than the smaller AMC V8s, as well as a forged steel crankshaft and connecting rods . Forged cranks and rods were used for their known strength—there

2940-441: Is a reenactment of the classic Tyrannosaurus rex chase scene from the 1993 movie Jurassic Park . However, instead of a 1992 Wrangler (YJ) Sahara Edition, Jeff Goldblum , who played Ian Malcolm in the movie, drives a silver two-door 2018 Wrangler JL Rubicon with red accents. The commercial ends with Goldblum seated in the driver's seat of the aforementioned Jeep in a showroom, where a Jeep saleswoman asks if he would like to take

3045-415: Is available on all models. Paired exclusively with the 850RE Torqueflite eight-speed automatic transmission and including the eTorque system, the engine produces 270 hp (201 kW; 274 PS) and 295 lb⋅ft (400 N⋅m) combined. This is the only gasoline engine offered in Europe, China, Singapore, and India. In North America, this engine had late availability, and the Wrangler was launched with

3150-779: Is designed to be more comfortable on-road and has recirculating ball steering with electric power assistance . The Wrangler is 2.5 inches (64 mm) longer overall than before, while the Wrangler Unlimited has grown by 3.5 inches (89 mm). The new Wrangler is roughly 90 kilograms (198 lb) lighter than the Wrangler JK. Overhangs increase significantly with the new model having 29.2 and 40.8 inches (740 and 1,040 mm) front and rear. The 2024 facelift can be optioned with 35 inch beadlock tyres and has official support for 40 inch tyres. The 3.6 L Pentastar VVT V6 gasoline engine still remains available from

3255-404: Is measured at the flywheel for both systems. For example, even with the modifications to reduce emissions and increase efficiency, AMC's 401 cu in (6.6 L) engine was among the strongest factory-spec engines available in an American car in 1971, with more horsepower than Pontiac 's standard 455 cu in (7.5 L) and Chevrolet 's 454 cu in (7.4 L) that powered

Jeep Wrangler (JL) The Jeep Wrangler (JL) is the fourth generation of the Wrangler off-road vehicle , available in two- and four-door bodies. Unveiled at the 2017 Los Angeles Auto Show on November 29, 2017, production of the vehicle began in November 2017. The 2-door Wrangler and 4-door Wrangler Unlimited feature an exterior design that

3465-408: Is not related or manufactured by Chevrolet , whose 327 V8 was introduced five years later in 1962. The AMC 327 engine debuted in a special edition 1957 Rambler Rebel , of which 1,500 were made. They were an early American muscle car . All Rebels had silver paint with a gold-anodized "spear" on each side. The 327 was not available in any other Rambler models in 1957. The Rebel's engine differs from

3570-666: Is purely a coincidence. The AMC 360 has a displacement of 359.80 cu in (5,896.1 cc). The 2-barrel produced 235 hp (175 kW; 238 PS) to 245 hp (183 kW; 248 PS) in 1970 to early 1971 while the 4-barrel produced 285 hp (213 kW; 289 PS) to 295 hp (220 kW; 299 PS), 175 hp (130 kW; 177 PS) to 220 hp (164 kW; 223 PS) from mid-1971 through 1975, 140 hp (104 kW; 142 PS) to 180 hp (134 kW; 182 PS) in 1976, 129 hp (96 kW; 131 PS) in 1977, and 160 hp (119 kW; 162 PS) from 1978 through 1991. This engine

3675-532: Is reminiscent of the 1997 through 2006 Wrangler (TJ) , with a "raked" front grille with seven vertical slots and round headlamps that integrate into the front grille. The designers have moved the traditional Jeep logo off the grille. The Wrangler has retained a body-on-frame construction and solid axles . The vehicle is offered with three different four-wheel drive systems: Command-Trac, Selec-Trac, and Rock-Trac. Options available on all JL models (except Rubicon) include an anti-spin rear differential . The JL

3780-819: The Bendix -developed system in December 1956 were followed in March 1957 by an AMC price bulletin offering the EFI option on the Rambler Rebel for US$ 395, but due to supplier difficulties, fuel-injected Rebels were only available after June 15. Teething problems with the Electrojector unit meant that only a few engineering and press cars were built, estimated to be no more than six units. At least two pre-production Rebels with EFI, however, are known to have been built. One

3885-644: The Bricklin SV-1 sports car for the 1974 model year. The 360 was the last AMC V8 to be manufactured. It continued to be produced after Chrysler bought American Motors in 1987 as the standard engine in the Jeep Grand Wagoneer through 1991, with the only modification being the "360" casting replaced with "5.9L" on the side of the block. The 390 cu in (6.4 L) AMC V8 produced 325 hp (330 PS; 242 kW) and 420 lb⋅ft (569 N⋅m; 58 kg⋅m) of torque in all except

3990-559: The crankshaft centerline, forming a very rigid crankcase gallery. The oil system feeds a central gallery to the cam and crankshaft first from front to rear and then dividing at the front to feed the two lifter galleries from front to rear. From the rear of the two lifter galleries oil is then supplied up to the two rocker arm shafts which serve as galleries to lubricate the valvetrain . The fore and aft direction changes are designed to eliminate stale oil areas which tend to form sludge deposits. American Motors' first V8 in-house engine,

4095-431: The 1955 Nash Ambassador and Hudson Hornet . These Packard V8s were supplied with extra-thick head gaskets to reduce power output and came mated to Packard " Ultramatic " automatic transmissions only. In addition to the verbal agreement, Packard sent AMC some parts bids, but these were rejected as too expensive. George W. Romney , AMC's new leader, decided against further relationships with Packard shortly after entering

4200-495: The 2007-2017 Jeep Wrangler (JK) . In March, Jeep announced a new concept at the Easter Jeep Safari in Moab, Utah. The J-12 is based on a modified Wrangler Unlimited chassis with a 18-inch (457 mm) frame extension allowing the use of a 6-foot (1,829 mm) load bed. The styling resembles the classic 1960s-era Jeep Gladiator truck and features "old-school" 16-inch smooth steel wheels with 36-inch tires, as well as

4305-425: The 250 was discontinued with a new 287 cu in (4.7 L) version replacing it in 1963. All these engines share common external dimensions, lightweight - about 600 lb (270 kg) - forged crankshaft and rods, as well as most other parts. The stroke for all Gen-1 V8s is 3 + 1 ⁄ 4 -inch (82.6 mm). Engine displacement was a factor of the bore : the 250 cu in (4.1 L) has

4410-647: The 250, was used in AMC automobiles from 1956 through 1961. It was a modern OHV/pushrod engine design and made its debut in the Nash Ambassador and Hudson Hornet "Specials" of 1956. These cars had the top-of-the-line model trim, but were built on the shorter wheelbase (Statesman and Wasp) models (hence the name "Special"attached). The 250 uses solid lifters and came in two- and four-barrel carburetor varieties (4V only in Nash/Hudson "Specials"). The 250 V8

4515-453: The 327s installed in the 1957 Nash Ambassador and Hudson Hornet models in that it uses mechanical valve lifters and a higher compression ratio. Since both engines were rated at 255 hp (190 kW), it is probable that the Rebel's was underrated. The Nash Ambassador and Hudson Hornet "Special" models were dropped after 1957, replaced by the 1958 Rambler Rebel with the 250 V8. The Rebel was

4620-489: The 392 cu in (6.4 L) HEMI V8 also found in Dodge's Scat Pack Charger alongside Jeep's own SRT Grand Cherokee . There are three updated infotainment systems (Uconnect 3 5.0BT, Uconnect 4 7.0, and Uconnect 4C 8.4N). The different Uconnect infotainment systems supply 5-inch, 7-inch, or 8.4-inch pinch-to-zoom displays. The base Sport and upgraded Sport S both feature the standard Uconnect 3 5.0BT system, while

4725-735: The AMC "tall-deck" 360 cu in (5.9 L) version until 1991 for use in the Jeep Grand Wagoneer SUV. This engine is most commonly referred to as the Rambler V8. It's also referred to as the AMC GEN1 (first generation AMC V-8) and sometimes as the Nash V8. Design work on AMC's first V8 engine began in 1954, yielding an engine produced in three displacements between 250 cu in (4.1 L) and 327 cu in (5.4 L) from 1956 until 1966 - including

4830-521: The CJ and the Cherokee. The 1980 (1981 model year) Laredo package was perhaps the most luxurious one, including leather bucket seats, leather-wrapped steering wheel, chrome interior trim, and a state-of-the-art Alpine sound system. Jeep has shown numerous concept pickup trucks, and officials at the automaker have "expressed interest in putting such a vehicle into production." A production-ready version of

4935-495: The Classic instead of a separate model. When the 250 was discontinued in 1961. A V8 engine was not offered in the Rambler models with the exception of the 327, which was only available in the top-of-the-line Ambassador. Dealers complained, so the 287 cu in (4.7 L) V8. was introduced in mid-model year 1963 as an option for the "mid-size" Rambler. Like the 327, it uses hydraulic valve lifters. Only two-barrel models were produced, there were no four-barrel options from

5040-559: The Corvette. The 304 has a displacement of 304 cu in (5.0 L), which produced 210 hp (157 kW; 213 PS)(gross rating) in 1970-71 and was built starting in 1970. Output declined yearly thereafter, initially due a shift from SAE Gross to SAE Net horsepower. 1972-75 models were rated at 150 hp (112 kW; 152 PS) (net rating from 1972 onwards). It was rated at 130.5 hp (97 kW; 132 PS) in 1978, and 125 hp (93 kW; 127 PS) in 1979,

5145-522: The Honcho package varied from year to year, but "always included the wide-track look of the Cherokee Chief." The Honcho was one in a series of special decal packages offered for J-Series trucks in the mid to late 1970s, which included the 1977–1979 Golden Eagle and the 1978 "10-4" version which offered an optional Citizens' Band radio along with the decals. The Honcho package was only available on

5250-670: The J-100 panel delivery, were dropped due to poor sales. For 1968, the flared-fender Thriftside models were dropped while a new camper option was added for the J-3600. From 1968 to 1971 Jeep pickups offered the Buick 350 cu in (5.7 L) 230 hp (172 kW; 233 PS) Dauntless V8 as an optional engine. American Motors Corporation (AMC) purchased the Kaiser Jeep operations in 1970 when Kaiser Industries decided to leave

5355-655: The JL for a test drive, to which Goldblum replies that he has. The all-new 2020 Jeep Gladiator was introduced at the 2018 Los Angeles Auto Show on November 28, 2018. Based on the Wrangler JL, the Gladiator features exterior and interior styling cues similar to the Wrangler Unlimited, seating for five passengers, and a five-foot pickup bed. For the 2024 model year , the Jeep Wrangler and Wrangler Unlimited JL receive

From 1976 to 1983 the "Honcho" trim package was offered on the J10 pickup. It consisted of bold striping with decals and was offered with factory extras such as the Levi's interior or a roll bar . The content of

5565-420: The Rebel was a far more-advanced setup than the mechanical types then appearing on the market and the engines ran fine in warm weather, but suffered hard starting in cooler temperatures. All the EFI cars were reportedly converted to four-barrel carbs before being sold; none are known to have existed outside the engineering department at AMC. The main problem was that early electronics were not fast enough for "on

5670-600: The Wrangler's structure had minimal intrusion and the dummy had minor injury readings, the IIHS concluded that the risk of a passenger being ejected from the vehicle was too high and gave the Wrangler a "Marginal" rating. Despite claims from Jeep that the JL Wrangler's structure was modified to prevent the same outcome, the vehicle overturned again during a retest for the 2022 model, despite some minor suspension changes, resulting in another "Marginal" rating. The 2022 Wrangler

5775-491: The automobile business. The Jeep trucks moved to all AMC engines to improve performance and standardize production and servicing. The Buick engine was replaced by the 360 cu in (5.9 L) or 401 cu in (6.6 L) AMC V8s . In 1970, the Gladiator's front grille was changed to the same design as the Jeep Wagoneer SUV. This was the truck's first styling change since its introduction. An AMC badge

An eight-speaker audio system, with dashboard and rear "sound bar" mounted speakers is standard on all models, whereas an optional nine-speaker Alpine premium amplified audio system that adds an all-weather subwoofer , is a standalone option on all models, also included with the Electronic Infotainment Group and Infotainment II Group on Sport S, Sahara, and Rubicon models. All three infotainment systems include

5985-530: The broader range of Dodge trucks. Chrysler discontinued the full-size Jeep trucks, but continued to build the luxurious and highly profitable Grand Wagoneer , which shared the chassis with the large pickups. After the Chrysler buyout, the compact Jeep Comanche pickup (based on the Jeep Cherokee (XJ) platform) received only minor changes and its production continued until 1992. Military versions of

6090-506: The civilian Jeep pickup included the M715 and M725, built from 1967 to 1969. They were built under contract for nations in addition to the United States. The idea was to reduce costs by starting from a civilian truck and sharing parts with the normal production-line truck, like the later " Commercial Utility Cargo Vehicle " (CUCV) for the military as a 5 ⁄ 4 ton tactical vehicle. The Swedish Air Force acquired 450 Gladiator vehicles in

6195-464: The clean sheet V8 into production in less than 18 months due in part to being able to apply the research and development efforts that were done by Kaiser-Frazer for engines that never reached production. One of AMC's engineers, David Potter, had worked on developing V8 engines for Kaiser-Frazer. American Motor's first V8 engine debuted having 250 cu in (4.1 L) in 1956 with a 327 cu in (5.4 L) version in 1957. Production of

6300-405: The dog-leg exhaust ports and 50-52 cc combustion chambers. They are commonly identified by the first three (319) or last three (291 for the 360-401 heads; 304 used a different casting) digits of the casting number. There was a U.S. auto industry-wide shift to lower compression ratios in mid-1971, so AMC increased combustion chamber size to 58-59 cc. The first three digits of the casting number on

6405-516: The early 1970s, which saw extensive use during the Lebanese Civil War (1975–1990). Many of these vehicles fell into the hands of the various competing Lebanese militias, who either used them for logistical and transport operations or modified them to be used as technicals , fitted with heavy machine guns or anti-aircraft autocannons . From 1975, Jeep tried making their pickups more "car-like" and appealing to consumers, starting with

6510-549: The early 1980s. They were given the local designations Klargöringsbil 9711 and Klargöringsbil 9712 , with the latter variant being equipped with a hard cargo bed top. The vehicles were modified to be used by aircraft groundcrew for mobile flight line operations in the Swedish Bas 90 system and could carry trailers with equipment and tow aircraft. It is often informally referred to as "The Dallas Jeep". The Lebanese Armed Forces acquired many M715 and Gladiator SJ versions in

6615-459: The eight-speed automatic transmission now require the 2.0L "Hurricane" turbocharged inline four-cylinder (I4) gasoline engine, except for the Sahara, High Altitude, Rubicon, and Rubicon X trims, which all offer the 3.6L Pentastar V6 gasoline engine with the automatic transmission. The previous 3.0L EcoDiesel turbocharged diesel V6 engine has been discontinued for 2024, although remains an option on

6720-519: The engine design is unique. The Gen-2 AMC V8 was first introduced at 290 cu in (4.8 L) in 1966. It was used exclusively in the Rambler American model in the first year. The 343 cu in (5.6 L) came out in 1967 and the AMX 390 cu in (6.4 L) arrived in mid-1968. These engine blocks were unchanged through the 1969 model year. The head used during this time

6825-581: The existing 3.6 L Pentastar V6 gasoline engine. Jeep cancelled the 2.0L eTorque hybrid in 2020. A 3.0 L EcoDiesel V6 turbodiesel engine , built by VM Motori , became available in North America in 2020 (same engine already available in the Jeep Grand Cherokee (WK2) and the Ram 1500 . ) It produces 260 hp (194 kW; 264 PS) and 600 N⋅m (443 lb⋅ft). For

6930-518: The existing Wrangler and Wrangler Unlimited, and is standard on all models, though has been redesigned for improved fuel economy. The engine features an Aisin AL6 six-speed manual transmission as standard equipment, with an 850RE Torqueflite eight-speed automatic transmission being optional. The automatic transmission made its debut in the 2018 Jeep Grand Cherokee (WK2) , replacing the older Torqueflite 845RE unit. The eight-speed automatic unit will feature

7035-596: The exterior color choice). Leather-equipped Sahara and MOAB include an interior color-keyed stitched vinyl dashboard. Safety improvements include standard side-impact airbags and strengthened B-pillars . Driver-assist safety features are located in the Active Safety group. The JL has a lowered beltline with larger windows for better outward visibility. The rear spare tire has been moved down to increase rear visibility. LED front headlamps and rear tail lamps are available, as are daytime running lamps (DRL's) on

7140-408: The factory for the 287 as this was the economy model V8. The 287 engine was produced through the 1966 model year. The AMC 327 is similar to the 287 , but displaces 327 cu in (5.4 L) due to the bore increase to 4 inches (101.6 mm). Unlike the 250, most 327s were produced with hydraulic valve lifters. All Gray Marine 327s came with solid lifters, as did the 1957 Rebel. The AMC V8

7245-547: The first station wagon-type development vehicle. Introduced in 1962 for the 1963 model year , the Gladiator was a conventional body-on-frame pickup design that shared its basic frame architecture and front end with the Jeep Wagoneer four-wheel-drive station wagon. Gladiators were available in RWD and 4WD , with optional dual rear wheels. A remarkable innovation was the available independent front suspension (IFS) instead of

7350-410: The flow was forced to go down into the exhaust manifolds. By switching to a convex floor the curvature of the flow starts in the head and proceeds much more smoothly into the exhaust manifold resulting in less turbulence and better flow. The center two intake bolts on each head were relocated to prevent accidental mix-ups of Gen-2 and Gen-3 intakes. AMC heads 319 and 291 used between 1970-mid 1971 have

7455-417: The fly" engine controls. This setup was utilized by Chrysler for the 1958 model year on its Dodge , Chrysler, Plymouth , and DeSoto carlines. It too failed, having the same problems. Bendix licensed patents based on their 1950s design (patent dated 1960) to Bosch , who perfected it as the basis for their D-Jetronic , et seq. injections system, first used in 1967. The 250 and 327 were also offered as

7560-444: The front fenders. A blind spot monitor is built directly into the taillight housing. The JL received 1 star from Euro NCAP in 2018. In 2020, a 4-door JL Wrangler Unlimited overturned upon impact with the rigid barrier during the IIHS's 40-mph small overlap test. When the vehicle struck the barrier, the front axle tucked underneath the Wrangler's structure, causing the vehicle to ride over its own axle and land on its side. While

7665-544: The front seat backrests, depending on model). Luxury leather-trimmed seating surfaces are standard on the MOAB and 392 trim level, and optional only on Sahara and Rubicon models (the front seat backrests are also embroidered with either the 'SAHARA', 'MOAB', 'RUBICON', or 'RUBICON 392' logos, depending on model). Interior colors are either Black or Heritage Tan for cloth-equipped models, or Black or Saddle on leather-equipped models. All models can be equipped with heated front seats and

7770-447: The highly optioned Super Wagoneer from 1966 until 1968. Kaiser-Jeep switched to the Buick 350 in 1967 after AMC discontinued the 327. The Buick V8 engine option continued through 1971 after which Jeeps returned to AMC V8 engines, American Motors having purchased Jeep from Kaiser in 1970. There were low- and high-compression versions of the 327 starting in 1960. Prior to 1960, all 327s were high compression. All low-compression models used

7875-648: The interior switchgear in the JL is unique to the JL, except for some parts which are shared with other Chrysler products. The power window controls remain in the center of the instrument panel, and the front woofers remain in the lower corners of the instrument panel. There is a new three-spoke, retro -inspired steering wheel, and a color instrument cluster display screen is available on upper-level trims. Standard cloth seating surfaces are standard on Sport and Sport "S", while upgraded Premium Cloth seating surfaces are standard on Sahara and Rubicon models (the upgraded seats include either 'SAHARA' or 'RUBICON' embroidery on

7980-508: The large chamber heads are 321, 322, or 323 depending on year. The only difference between small and large chamber Gen-3 heads is the combustion chamber size. The advertised power drop from the 1971 ratings to the ones for the 1972 model years (for example, the 1971 304 produced 210 hp and the 1972 304 was 150 hp) is not due to any engine changes, but an industry-wide shift from SAE Gross (also known as "brake horsepower" or "bhp") to SAE Net power ratings. The 1971 and 1972 engines produce

8085-577: The last year it was installed in passenger cars, and in 1980–81, the last years it was used in Jeep vehicles. The International Harvester Corporation 304-cubic-inch (5.0 L) SV "Comanche" V8 engines are sometimes mistaken for the AMC 304, however, the IHC V8 engine family has no relation to the AMC V8 and was in fact first produced in 1959, 11 years prior to the AMC designed 304. The similarity in displacement

8190-460: The new engines utilized "thin-wall" casting technology and weighed only 540 pounds (245 kg). and produced in three displacements - between 290 cu in (4.8 L), 343 cu in (5.6 L) and 390 cu in (6.4 L) - until 1969. All three engines share the same basic block design and external measurements; the different displacements are achieved through various bore and stroke combinations. Bore center measurement

8295-531: The new full-time four-wheel drive system, Selec-Trac, replace Quadra-Trac. From 1981 to 1985 a re-bodied version of the J-10 was built and sold as the Jeep CJ-10 , featuring a CJ-like nose and cab, as well as a very boxy redesigned rear truck-bed, somewhat resembling that of a Land-Rover. Chrysler bought out AMC in 1987. The full-size Jeep Pickup line was not only an aging model, but also competed directly with

8400-461: The pickup market using the Gladiator nameplate for a four-door midsize truck based on the Jeep Wrangler platform. The new Gladiator is in concept similar to the compact two-door Jeep CJ-8 (Scrambler), a long wheelbase version of the CJ-7 made from 1981 through 1986, but offering more amenities and features. The first Jeep pickup development mule was operational around May 1960, about three months after

8505-455: The position of CEO in October 1954 after Mason's sudden death. It is said that Romney gave orders to design an in-house V8 engine as quickly as possible. Directly quoting the original 1956 SAE Article entitled "The New American Motors V8": The entire program was under the direction of Meade F. Moore, Vice-President of Automotive Research and Engineering, and through his efforts, the project

8610-785: The related Jeep Gladiator (JT) . Two previously-available exterior paint colors return as "special-edition" options for 2024: Punk'n Metallic (Orange) and Bikini Pearl Coat Metallic (Teal Blue). All models receive automatic air conditioning and climate controls. The refreshed 2024 Wrangler lineup went on sale in the spring of 2023. The JL is available in a number of trim packages: AMC V8 engine#360 The AMC V8 may refer to either of two distinct OHV V8 engine designs that were developed and manufactured by American Motors Corporation (AMC). The engines were used in cars and trucks by AMC, Kaiser, and International Harvester as well as in marine and stationary applications. Contrary to long-believed misinformation, from 1956-1987, AMC never installed

8715-423: The rest of the world (except North America) a 2.2 L 16V Multijet II turbo four-cylinder diesel engine producing 200 hp (149 kW; 203 PS) and 450 N⋅m (332 lb⋅ft) with Start&Stop is available. A plug-in hybrid model called the 4xe was released in 2021. Power and torque ratings are 375 hp (280 kW; 380 PS) horsepower and 470 lb⋅ft (637 N⋅m) of torque. It uses

8820-420: The same as some big-block engines. The only parts shared between the 1966-67 Rambler V8 and 1966-91 AMV8 are the lower cam timing sprocket and the timing chain. The AMC V8 was not built by Ford or anyone else although it bears an uncanny resemblance to the later Buick V8 engines (400, 430, 455). It shares the same design employing a timing gear case that mounts both the distributor and oil pump. It also shares

8925-418: The same displacement by using a special connecting rod and piston for this year only. It is believed that AMC kept the 390 this last year due to the reputation it had garnered in the two-seater AMX, then still in production. (It was discontinued after 1970). In 1971 the 390 was also stroked by the same 0.16 in (4.06 mm) as the other two versions of the engine to become the 401. The other change in 1970

9030-401: The same oiling scheme employing a single passage to feed both cam and crank from the right lifter bank by tangentially intersecting the cam bore instead of two drilled passages, one from the cam to crank and another from the crank to the right lifter bank. Some electrical parts (starter and distributor) were shared with Ford, and some models used Motorcraft (Ford) carburetors, but the balance of

9135-428: The same power. The 1971 and earlier versions were rated using "gross" horsepower, which is with the engines operating with no accessories or drive belts , air filters, nor any exhaust system restrictions. The change to the more realistic "net" horsepower ratings for 1972 and later required the engine to be driving all stock factory accessories and to use the factory air filter system and a simulated factory exhaust. Power

9240-483: The sportside (stepside) and short bed trucks. Between 1974 and 1983 an unknown amount of Honchos were produced, but the Sportside Honchos were made between 1980 and 1983, and only 1264 of these trucks were ever made. Decal packages were available for many of Jeep's vehicles in the 1970s, including a package for the Jeep Cherokee called the Cherokee Chief. The Golden Eagle package was also available for both

9345-566: The uplevel Sahara and Rubicon both feature the Uconnect 4 7.0 system with Apple CarPlay and Android Auto , which is also optional on the upgraded Sport S, when equipped with the Electronic Infotainment Group. The Uconnect 4C 8.4N system is only available on the uplevel Sahara and Rubicon models when equipped with the Electronic Infotainment II Group. SiriusXM Satellite Radio is standard on all models aside from

9450-766: The vehicle. The model designations were simplified for 1974, with the J-2000 and the J-4000, which designate wheelbase, being swapped out for the J-10 and J-20, designating payload capacity. Larger brakes were made standard and the turning radius was reduced. The Quadra-Trac system was now available with all engines. The AMC 401 cu in (6.6 L) was offered from 1974 through 1978. These engines are known for their toughness and excellent power output. The 401 engine produced 330 hp (246 kW; 335 PS) and 430 lb⋅ft (583 N⋅m) of torque. For 1977, Jeep J-10 pickups included Dana 's manual four-wheel-drive system,

9555-505: Was also added to the grille after 1972. The Gladiator name was dropped after 1972, after which the line was known simply as the Jeep pickup or J-series. The pickups were designated as J2000 and J4000 models (the 3000 series was dropped in 1971) until 1973, then as J10 and J20 models from 1974 to 1988. From 1971 to 1972 Jeep pickups offered the AMC 304 cu in (5.0 L) 210 hp (157 kW; 213 PS) V8 as an optional engine. The AMC 258 cu in (4.2 L) I6 engine

9660-535: Was built in 1968 and 1969. In 1970, all three blocks grew in deck height and gained a new head design. Although the engine is an outgrowth of the Gen-2 V8, these changes cause it to be regarded as the third generation of AMC V8, or "Gen-3". The stroke and deck height on the 290 and 343 were increased by 0.16 in (4.06 mm) on both engines, becoming the 304 cu in (5.0 L) and 360 cu in (5.9 L), respectively. The 1970 AMX 390 remained at

9765-513: Was carried on cooperatively by our Kenosha and Detroit Engineering Departments. Obviously, such a division of both design and development required the utmost in teamwork by F.F. Kishline, Chief Engineer, and his assistants, E.L. Monson and J.S. Voigt in Kenosha, and by R.H. Isbrandt, Chief Design Engineer, and W.S. Berry, Chief Mechanical Engineer, in Detroit." The engineering team was able to get

9870-634: Was inadequate time for testing cast parts for durability without delaying AMC's introduction schedule. Once forging dies were made it was not cost-effective to test cast parts due to the relatively low number of engines produced. The use of these stronger components was also continued with the production of 401 engines. This is an advantage of these AMC engines when used in heavy-duty and high-performance applications because they have no problems with their connecting rods breaking; unlike other domestic automakers' large displacement small block engines. The Gen-2 AMX 390 produced 315 hp (235 kW; 319 PS) and

9975-486: Was intended to be launched in 2020, but was actually presented in 2021. Before the JL's actual debut at the 2017 Los Angeles Auto Show, the song Believer by Imagine Dragons was used in the opening. In the teaser, it uses 7 letters that are narrowed to represent the 7 vertical slots and 2 circles on the left and right to depict the front fascia. A debut television advertisement for the 2018 Wrangler JL, entitled "Jeep Jurassic", first aired during Super Bowl LII . The ad

10080-408: Was introduced in 1966 It is sometimes referred to as the "Gen-2" AMC V8. The first version was the completely new 290 cu in (4.8 L) Typhoon V8 introduced in a special mid-1966 model year "Rogue" hardtop. Available in 200 hp (149 kW; 203 PS) two-barrel carburetor version or producing 225 hp (168 kW; 228 PS) with a four-barrel carburetor and high compression,

10185-525: Was introduced in 1972 and offered through 1988. The engine produced 112 hp (84 kW; 114 PS) and 210 lb⋅ft (285 N⋅m) of torque. The AMC 360 cu in (5.9L) was offered in 1971 and through 1988. Producing in early versions 175 hp (130 kW; 177 PS) and 245 lb⋅ft (332 N⋅m) of torque. Later 360s produced 195 hp (145 kW; 198 PS) and 295 lb⋅ft (400 N⋅m) of torque. Throughout 1971-1972 The J10 received updates to its front-end design which "modernized"

10290-508: Was kept the same as the Gen-1 V8 at 4.75 in (120.7 mm) so that boring equipment could be reused. Other than that, this engine is vastly different from the Gen-1 model. The Gen-1 engine is physically the size of a big-block Ford or GM engine, and is sometimes called a "big-block". The Gen-2 is closer to the physical size of U.S.-made small-block V8s except for the bore centers, which are

10395-420: Was optional in the 1957 Rambler. All 1958-60 V8 Ramblers were called "Rebels" and designated as a different series. It is easy to confuse the 1957 Rambler V8 and the 1958-'60 Rebel line with the special 1957 Rambler Rebel , a limited edition muscle car (see 327 below). In 1961, The Rambler Six was renamed the " Rambler Classic " to avoid model confusion in the Rambler line-up. A V8 engine then became an option in

10500-625: Was safety tested by the IIHS : Production of the Wrangler Unlimited began in November 2017, while two-door Wrangler production will commence in early 2018. As with its predecessors, the JL is produced at Jeep's Toledo Complex in Toledo, Ohio , and also was produced alongside its predecessor, the Wrangler JK , which remained in production until April 27, 2018. The simultaneous sales were to ensure that dealerships could meet demand. The 2018 Wrangler JK

10605-435: Was sent to Daytona Beach, Florida for "Speed Week" (the forerunner of today's Daytona 500 ). It was the second fastest car on the beach, bested only by a 1957 Chevrolet Corvette with mechanical fuel injection , and only by a couple of tenths of a second. The EFI 327 was rated at 288 hp (215 kW; 292 PS) and the regular four-barrel carbureted model at 255 hp (190 kW; 259 PS). The EFI system in

10710-453: Was the so-called "rectangle port", named after its exhaust port shape. The 290 heads use smaller valves, 1.787 in (45.4 mm) intake and 1.406 in (35.7 mm) exhaust, corresponding with its small bore. The 343 and the AMX 390 use the same larger valve heads, 2.025 in (51.4 mm) intake and 1.625 in (41.3 mm) exhaust. The base 290 cu in (4.8 L) produced 200 or 225 hp (149 or 168 kW) with

10815-436: Was the switch to the "dog-leg" heads. These heads flow 20% better on the exhaust side than the 1966-1969 rectangular port heads and are thus the best for performance. There are two reasons for the flow increase: (1) the area of the port is larger, due to the dog leg and (2) the shape of the port floor was changed from a concave to a convex curve. The concave floor tended to bend the exhaust flow upwards which caused turbulence when

10920-416: Was used in the 1970 AMX as the base engine and also in the 1970 Rebel , the 1971 through 1978 Matador , Jeep J-series trucks from 1970 until 1987, Wagoneer (SJ) models from 1972 until 1984, Cherokee (SJ) from 1974 until 1983, as well as in the full-sized Grand Wagoneer from 1984 through 1991 - becoming one of the last carbureted engines used in an American-built vehicle. The 360 V8 was also installed in

11025-632: Was virtually unchanged from the 2017 model, and a Wrangler JK decal on the front fenders distinguished the outgoing model from its successor. The plant which produced the JK will temporarily close as it receives a retooling for the upcoming Wrangler-based Jeep Gladiator . FCA announced that the Toledo Machining Plant would assemble the power electronics module and components for the Jeep Wrangler Plug-in Hybrid which
