112-926: A DOHC four-valve-per-cylinder motor, borrowed from the E80 series Corolla . This engine was also equipped with Denso electronic port fuel injection and T-VIS variable intake geometry, giving the engine a maximum power output of 112 hp (84 kW) in the US, 128 hp (95 kW) in the UK, 116 or 124 PS (85 or 91 kW; 114 or 122 hp) in Europe (with or without catalytic converter), 118 hp (88 kW) in Australia and 130 PS (96 kW; 128 hp) in Japan. Japanese models were later detuned to 120 PS (88 kW; 118 hp). A five-speed manual transmission
168-420: A 1976 Toyota design project with the goal of a car which would be enjoyable to drive, yet still provide good fuel economy – not necessarily a sports car. Design work began in 1979 when Akio Yoshida from Toyota's testing department started to evaluate alternatives for engine placement and drive method, finalizing a mid-transverse engine placement. Toyota called the 1981 prototype SA-X . From its original design,
224-435: A challenge during testing, as the 222D also suffered from enormous turbo lag (as did most of the competitive Group B cars), but paired with the extremely short wheel base made driving at speed almost impossible. Toyota Team Europe owner Ove Anderson describes: "you never knew what it was going to do. With such a short wheelbase and such power in such a light car it could swap ends at any time, and without any warning". During
280-561: A more refined automobile, as is the nature of any TOM'S outfitted vehicle. Whilst the T020 was a normally aspirated vehicle, TOM'S also produced equipment for turbocharged models — e.g. wastegates, boost controllers, air filters, a 3S-GTE version of their "TOM'S Barrel" exhaust system, and "T.E.C. II" Engine Control Units. Despite the fact that these products are no longer purchasable brand new, some of these modification parts may still be procured as second-hand items, and are highly sought after by
336-460: A private collector in 2017, one in white, with a 50mm lengthened wheelbase and a more production styled body located in Tokyo. Although the 222D was still a prototype, it made it very far into development before Group B was canceled. Of the rumored eleven built, eight were destroyed in testing, indicating Toyota was considering bringing the 222D to competition. However, the short wheelbase proved to be
392-569: A production car and was effectively a purpose-built semi- sports-prototype that successfully got GT1 homologation. The overall construction method of this car (a heavily modified production car frontal chassis with race-built rear chassis combined into a style of semi-prototype) inspired Porsche to make 911 GT1 homologation specials which dominates the GT1, and foreshadowed the cancellation of GT1. List of Toyota model codes#W The following model codes have been used by Toyota . The letters of
448-421: A redesign in 1989 (though North America did not receive them until early 1990 as 1991 models). The new car was larger, weighed 350 to 400 lb (159 to 181 kg) more than its predecessor due to having a more luxurious and spacious cabin, larger engine sizes, sturdier transaxle, and a more durable suspension setup. The overall design of the automobile received more rounded, streamlined styling, with some calling
504-581: A run of 270 units, featured a special Midnight Blue paint, the MOMO -commissioned steering wheel and gear knob, Recaro "Milano" seats with matching door panels. The 1989 model also benefited from some of the last G-Limited model options, such as the LED rear spoiler brake light and more aerodynamic wing mirrors. Both "Super Edition" models had unique decals on the rear visor and side stripes. While Toyota's front-engine, rear-drive Celica rally cars proved dominant in
560-410: A surprise appearance at the 2006 Goodwood Festival of Speed , Toyota drove and displayed a black 222D. The race-ready car weighed around 750 kg (1,650 lb) and its transverse-mounted, four-cylinder, turbocharged engine (what appears to be a 503E race engine, though other prototypes may have used the 4T-GTE ) was reported to produce as much as 750 hp (559 kW). The MR2 went through
616-478: A time also produced a brake kit as well for the MR2, but this has been discontinued. Performance parts manufacturer JUN offered engine upgrades for the MR2's 3S-GTE engine which came in the form of stroker kits, which were co-developed with Cosworth , and also offered lightened flywheels, cam gears, and camshafts. The SW20 garnered generally favorable reviews during its production life, with various sources complimenting

#1732787917551672-399: A variety of tuning parts for the MR2. The "T020" as it was called, was powered by a naturally aspirated 2.2L stroked 3S-GE that produced 175 kW (235 bhp) at 6,800 rpm, this was due to more aggressive "F3" cams, a stroker kit, better intake flow with the aid of the "TOM'S Hyper Induction Carbon" intake kit, and an upgraded exhaust system labeled the "TOM'S Barrel", a lightened flywheel
728-654: A wide-body TRD2000GT replica car. This was to pay homage to the TRD2000GT wins in the GT-C Japanese racing series, since the TRD2000GT racing series cars were based on the SW20 floor pan. The TRD2000GT body kit widened the MR2 by a total of 100 mm (4 in). Prior to MR2s being fitted with the TRD2000GT body kit, TRD had its customers select which additional engine, suspension, wheel, and interior upgrades they wanted. For this reason, no two TRD2000GT MR2s are alike. It
784-453: Is a line of two-seater, mid-engined , rear-wheel-drive sports cars , manufactured in Japan and marketed globally by Toyota from 1984 until 2007 over three generations: W10 (1984–1989), W20 (1989–1999) and W30 (1999–2007). It is Japan's first rear mid-engined production car. Conceived as a small, economical and sporty car, the MR2 uses simple but effective design elements, including an inline-four engine , transversely mounted in front of
840-445: Is rumored that approximately 10 conversion kits were imported from TRD Japan into the US for conversions. In many respects, the extended body can be compared to that of a Porsche 911 Slantnose modification. The car's width is extended and body dimensions dramatically changing the car's overall visuals. Very little is known about these cars outside Japan. Apart from Toyota Racing Development, TOM'S also released official body kits and
896-588: Is rumored that at least one was built to produce up to 373 kW (500 bhp) whereas some others had few modifications to their engines. In order to ensure exclusivity, a high price tag was charged and total of just 35 factory car conversions were completed by Toyota Technocraft Ltd. Each official Technocraft-converted car was made using lightweight fiberglass components (front fenders, trunk lid extension, rear quarter panels, gas door, front and rear bumpers, 3-piece wing) and re-classified as completely new cars (with their own specially numbered TRD VIN plate riveted to
952-490: The "Turbo" emblem (US) on the rear trunk, 'TWIN CAM 16 TURBO' decal above the side intake (Japanese market), a fiberglass engine lid with raised vents, fog lights, and an added interior center storage compartment located between the two seats. All SW20 MR2s came with a staggered wheel setup, with wider wheels and tires in the rear than in the front. Mechanical differences on the Turbo models include: The US market MR2 Turbo model
1008-576: The 1/4 mile in 13.1 seconds, beating out more expensive and higher powered automobiles such as the Honda NSX, Toyota Supra RZ, and even the Ferrari 348 TB . Best Motoring, a popular Japanese automobile TV show, featured an episode that had them battle a factory stock Rev 5 GT-S Turbo versus other Japanese market contemporaries on the Tsukuba Circuit , with the MR2 winning the circuit race. In
1064-412: The 911 (993) GT2 for increased downforce at high speeds, and a reworked suspension set up with Öhlins equipment. Japanese tuner Border Racing, made available several parts as well, consisting mostly of parts that improved the car's suspension geometry, namely roll-center adapters, extended tie rods, etc., though they have also produced intercooler kits for the car and several interior pieces. AP Racing at
1120-520: The African Group B rallies of the 1980s, they were at a disadvantage on the twistier European stages. Thus, Toyota Team Europe started a rally project in 1985, codenamed "222D" based on the MR2, for competition in Group S and potentially Group B. Though somewhat similar on the outside, it is clear that the prototype had very little in common with the production car although the two appear to share
1176-509: The MR2 SW20 a "baby Ferrari" or "poor man's Ferrari" due to design cues similar to the Ferrari 308 GTB/GTS or Ferrari 348 . Like the AW11 before it, Toyota spent countless hours fine-tuning the handling capabilities of the SW20, seeking advice from professional race car drivers, including Dan Gurney of Formula One, NASCAR, and Le Mans fame. When the AW11 was still in production and before

#17327879175511232-670: The MR2 community. TOM'S still keeps a T020 part list on their website, and there are still T020 part catalogues in circulation between enthusiasts to this day, albeit second-hand. Between 1996 and 1999, Toyota TechnoCraft (TTC) produced 88 or 91 SW20 MR2 Spider convertible conversions. These cars featured a retractable cloth softtop roof and exclusive wingless trunk and engine lids. Most Spiders had automatic transmissions, naturally aspirated engines, and Lucerne Silver paint with blue side mouldings and black and blue accented cloth seats. The Toyota name and logo were not applied to these cars due to concerns about roof leaks. During its production,
1288-459: The MR2 number eight on the list of Top Sports Cars of the 1980s . In 1988 and 1989 Toyota produced two final production runs of fully optioned "Super Edition" MR2s, based upon the supercharged Japanese market model, and only sold in Japan. The 1988 'Super Edition' was a run of 300 units, had white/gold two-tone paint, bronze glass, unique half-leather and half-cloth seats, along with a MOMO -commissioned steering wheel and gear knob. The 1989 model,
1344-432: The MR2 was prone to "snap-oversteer" . As a counterpoint to the snap-oversteer phenomenon of the MR2, other journalists point out that most mid-engine and rear-engine sports and super cars exhibit similar behaviour, and that a change to the driver's response to oversteer is really the solution. In any car, braking shifts the weight forward, and acceleration to the rear. When drivers enter a corner with too much speed, and lift
1400-646: The MR2 won the Car of the Year Japan . As Toyota engineered the MR2 to accommodate a 2-liter engine, its primary features included its light body (as low as 950 kg (2,094 lb) in Japan and 1,066 kg (2,350 lb) in the US), strong handling, and low-power small-displacement engine. The car is often referred to as the AW11, referring to the chassis code of the most common 1.6-liter, A-engined versions. The MR2's suspension and handling were designed by Toyota with
1456-407: The SW20 enjoyed a myriad of tuning parts from Japanese tuners such as HKS, Blitz, Phoenix Power, etc. While some companies only offered aesthetic modifications for the SW20, others such as Phoenix Power offered modifications such as a tuned ECU, longblock modifications, and a trunk-mounted intercooler combined with a T04R Turbocharger. The Phoenix Power MR2 also featured a large rear wing reminiscent of
1512-438: The SW20 still has a large enough following to be labeled as a very challenging car to push to its limits, with some labeling it as "the most dangerous car that you can buy". Such a label may be true as MR2s are relatively cheaper than most automobiles with an MR platform ( Honda NSX , Ferrari F355 , Lotus Elise ) and that it is readily available to most people. Early in the 1990s, the SW20 enjoyed considerable success throughout
1568-477: The SW20 was officially shown to the public, several rumors were spreading stating that Toyota was building yet another mid-engine sports car, one that would have a 3.0-liter V6 engine that could directly compete with the 348, though this specific rumor was later shot down under the pretense that such a car would belong under the Lexus branding. Differences between the normally aspirated and turbocharged models include
1624-402: The T020 to accelerate from 0–60 mph (0–97 km/h) in 4.9 seconds, in turn further made the SW20 chassis a much more capable track machine. A sportier look was given to the vehicle as well through engine scoops, side skirts, a Ferrari 348 -esque rear light grille, forged wheels, revised bumper designs, and a larger rear spoiler. Though undeniably still an MR2, the T020 was in all essence
1680-421: The US market), Toyota introduced a supercharged engine for the MR2. Based on the same block and head, the 4A-GZE was equipped with a small Roots-type supercharger and a Denso intercooler . T-VIS was eliminated and the compression ratio was lowered to 8:1. It produced 145 hp (147 PS; 108 kW) at 6,400 rpm and 186 N⋅m; 137 lb⋅ft (19 kg⋅m) of torque at 4,400 rpm and accelerated

1792-402: The car evolved into a sports car, and further prototypes were tested both in Japan and in the US. Significant testing was performed on race circuits including Willow Springs , where former Formula One driver Dan Gurney tested the car. All three generations were in compliance with Japanese government regulations concerning exterior dimensions and engine displacement. The MR2 appeared around
1848-419: The car from 0 to 100 km/h (62 mph) in 6.5 to 7.0 seconds. The supercharger was belt-driven but actuated by an electromagnetic clutch, so that it would not be driven except when needed, increasing fuel economy. Curb weight increased to as much as 2,494 lb (1,131 kg) for supercharged models, due to the weight of the supercharger equipment and a new, stronger transmission. A fuel selector switch
1904-458: The early 2000s. SARD (Sigma Advanced Research Development) built a heavily modified and lengthened version of the SW20 for GT racing called the SARD MC8-R. It used a heavily modified MR2 frontal chassis with a custom rear chassis made to fit a twin-turbo version of the 4.0-liter 1UZ-FE V8 producing 600 bhp (447 kW). This is the first car which only used the frontal chassis of

While TRD Japan only offered a small number of kits with all body parts required for third-party conversion, Toyota Technocraft Ltd. offered complete car conversions. Apart from the cars listed on the TRD2000GT register it is unknown how many original Toyota Technocraft Ltd. cars still exist today, but it
2016-478: The help of Lotus engineer Roger Becker. Toyota's cooperation with Lotus during the prototype phase can be seen in the AW11, and it owes much to Lotus's sports cars of the 1960s and 1970s. Toyota's active suspension technology, called TEMS , was not installed. With five structural bulkheads, the MR2 was quite heavy for a two-seater of its size. Toyota employed the naturally aspirated 4A-GE 1,587 cc (1.6 L; 96.8 cu in) inline-four engine ,
2072-415: The likelihood that this would occur, though many drivers would lament the change and claim that it "neutered" the sharp edge the MR2 was known for. Toyota claimed that the changes were made "for drivers whose reflexes were not those of Formula One drivers". In 1998, Toyota Racing Development offered an official kit body conversion and tuning program for MR2 owners to transform their existing SW20 MR2 into

This was also noticed in the rear sway bar removal for the MY 1986. Some MY 1986 cars have a rear sway bar, while the mounting tabs on the strut housing were either there for both sides, only one side, or none at all depending on when Toyota ran out of
2408-522: The older rear struts with mounting tabs as production used up parts. American car magazines Road & Track and Car and Driver both chose the MR2 on their "ten best" car lists. The Australian Wheels magazine chose the 1988 MR2 as its favourite sports car. The MR2 was Motor Trend ' s Import Car of the Year for 1985. The MR2 was also on Car and Driver magazine's Ten Best list for 1986 and 1987. In 2004, Sports Car International ranked

The name MR2 stands for either " m id-ship r un-about 2 -seater" or " m id-engine, r ear-wheel-drive, 2 -seater". In French-speaking markets, the vehicle was renamed Toyota MR because the abbreviation "MR2" sounds like the profanity "merde" when spoken in French. The MR2 derived from

This model was never offered outside of the Japanese and North American markets, although some cars were privately imported to other countries. MK1a and MK1b are unofficial designations, but are frequently used by owners and vendors to distinguish between early production vehicles and later face-lifted models. While there are considerable differences detailed below,
2632-523: The same factory AW11 floor pan. Little else is known about the project as it never competed. With Group B cancelled in 1986, the proposed Group S regulations suffered the same fate, and the remaining prototypes were reduced to museum pieces and private collections. Supposedly eleven prototypes were made, of which eight were destroyed during testing, leaving only three known examples: Two in black, one stored at Toyota Gazoo's facility in Cologne and one sold to

Toyota debuted its SV-3 concept car in October 1983 at the Tokyo Motor Show , gathering press and audience publicity. The car was scheduled for a Japanese launch in the second quarter of 1984 under
2744-417: The styling, power, and responsive handling. Car and Driver noted the revised SW20's braking capabilities to be superb, stating that 70 mph to standstill could be done in 157 feet, rivaling that of the Honda NSX. Former Top Gear host and racing driver Tiff Needell commends the SW20's handling having said that it "encourages you to drive with enthusiasm" in a review back in 1990. He does note however, that
2800-449: The sudden transition from understeer to oversteer may be startling for some people. The car is infamously known for its "snap-oversteer" phenomenon. This notoriety comes from numerous instances where individuals crash their SW20s either on or off the race track due to inexperience with a mid-ship platform, as MR layouts handle very differently in comparison to the more common FF or even FR layouts. Even in its revised state from January 1992,
2856-414: The throttle mid-corner, the weight transfers forward causing the rear tires to lose traction (called lift-off oversteer), which can result in a spin. When improper steering inputs were made attempting to correct this non-power-on oversteer, the rear of the MR2 would swing one way, then wildly (and quickly) the other—thus the term "snap" oversteer. Toyota elected to change the MR2 suspension and tires to reduce
