77-683: The Vauxhall Velox is a six-cylinder executive car which was produced by Vauxhall from 1948 to 1965. The Velox was a large family car, directly competing in the UK with the contemporary six-cylinder Ford Zephyr , and to a slightly lesser extent, with the A90, A95, and A110 Austin Westminster models. It was introduced by Vauxhall shortly before the London Motor Show in October 1948, as
154-478: A V6 engine or V8 engine , but longer than straight-four engines , V6s, and most V8s. Straight-six engines are typically produced in displacements ranging from 2 to 4 L (122 to 244 cu in), however engines ranging in size from the 0.7 L (43 cu in) Benelli 750 Sei motorcycle engine to the 6.7 L (409 cu in) Cummins B Series engine pickup truck engine have also been produced. Due to its well-balanced configuration,
231-626: A 1.8 L flathead petrol engine used by the Opel 8/40 PS . The displacement of this engine was expanded as it was used in later models such as the Opel Kapitän and Opel Admiral , with later versions switching to an overhead valve (pushrod) design. In 1968, the straight-six versions of the Opel CIH engine were introduced, initially using a single overhead camshaft (SOHC) with some later versions using double overhead camshafts (DOHC). Production of
308-543: A 400 kg van version (built by Geser of Lucerne ) was a common sight in the 1950s serving as Swiss Post Office vehicles. Despite the lack of bumper over-riders suggesting the four-cylinder Wyvern powerplant, all vans were Veloxes. Conventional Velox and Wyvern four-door saloons were assembled at the General Motors plant at Biel . Also built in Switzerland was a unique prototype two seater roadster known as
385-531: A V6 engine replaced it. The Nissan TB overhead valve engine was introduced in 1987 and produced alongside the other straight-six engines. The six-cylinder versions of the Prince G engine were introduced in 1963 and remained in production until 1969, three years after Prince's merger with Nissan. The 1969–1973 Nissan S20 dual overhead camshaft engine (used in the Nissan Fairlady and first generation of
462-436: A claimed top speed of 74 mph (119 km/h). Power was delivered to the rear wheels via a three-speed manual gear box with synchromesh on the top two ratios. Optional extras included a heater from which warm air was evenly distributed between the front and back areas of the passenger cabin and which could be set to de-ice the windscreen in winter or to provide cool air ventilation in summer. Also available at extra charge
539-533: A lower-cost version of the Oakland six, powered by the Pontiac Split-Head Six flathead engine, which used two cylinder heads. This engine was replaced by the 1941–1954 Pontiac flathead six . The unrelated Pontiac OHV 6 overhead valve engine was produced in 1964–1965, based on a Chevrolet design. Pontiac's final straight-six engine was the 1966–1969 Pontiac OHC 6 overhead camshaft engine, which
616-399: A more powerful 3294 cc engine. The 2.6 was retained for some export markets in which government tax thresholds penalised buyers and users of cars with engine sizes above 2800 cc. The update also included a new full-width grille, new tail lights incorporating optional reversing lights, twin rear exhaust pipes, 120 mph speedometer (was 110), new interior trim and, towards the end of
693-783: A new flagship model, the Vauxhall Viscount , was launched. The Velox and its Opel contemporaries are remembered for having mirrored North American styling trends (e.g. the Ponton style of body) much more closely than other European models of the time. That was particularly apparent following the 1957 introduction of the PA version of the Velox. The classic four-door saloon boasted a newly developed straight-six-cylinder engine of 2,275 cc (138.8 cu in), with overhead valves . The 54 bhp (40 kW) power output provided for
770-493: A rectangular cluster with "magic ribbon" speedometer – the strip indicating speed changed from green to amber at 30 mph and to red at 60 mph. There was also a new engine, still of six cylinders, but now increased in capacity to 2651 cc, and delivering 95 bhp (71 kW). The UK had recently embarked on its first programme of motorway building, and the Velox now boasted a straight line maximum speed of 94 mph (151 km/h). Velox models were also assembled at
847-412: A residual 6th-order-and-up inertial torque oscillation compared with the four-stroke design being imbalanced at 3rd-order and up. Crankshafts for straight-six engines usually have either four main bearings (i.e., a bearing in between each pair of crankpins and one at each end) or seven main bearings (i.e., a bearing between every crankpin): The first production straight-six engine was introduced in

#1732790666741924-455: A single overhead camshaft engine in 1979 and upgraded to dual overhead camshafts before production ended in 2008 (with the 1G-FE being the final variant). Nissan's first straight-six engine was the 1950–1952 Nissan NAK flathead petrol engine, which continued in various forms until production of the Nissan P engine ended in 2003. The 1963-1965 Nissan K overhead valve petrol engine was used in
1001-496: A straight line along the crankshaft . A straight-six engine has perfect primary and secondary engine balance , resulting in fewer vibrations than other designs of six or fewer cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines became more common in the 1970s. By the 2000s, V6 engines replaced most straight-six engines. In terms of packaging, straight-six engines are almost always narrower than
1078-597: A straight six version of the Chrysler flathead petrol engine. This was replaced by the 1959–2000 Chrysler Slant-6 overhead valve straight-six petrol engine, which was so named due to the 30-degree angle used to reduce the height of the engine (with the trade-off of a wider engine). The Slant-6 was released in the Dodge Dart economy car and used in many models until a V6 engine replaced it after 30 years. The Chevrolet Stovebolt overhead valve straight-six petrol engine
1155-415: A straight-six was the 1961–1969 Alfa Romeo 2600 executive car before the company switched to V6 engines. Mercedes-Benz's history of straight-six engines began with the 1913 Mercedes D.I aircraft engine. The first automotive straight-six engine was the 1924–1929 Daimler M836 3.9 L petrol engine. Following World War 2, Mercedes resumed production of straight-six engines with the 1951 introduction of
1232-501: A successor to the Vauxhall Fourteen . Between 1948 and 1957 the Velox shared its body with the less-powerful four-cylinder Vauxhall Wyvern . From August 1954 through to October 1965, it shared its body with the more luxuriously equipped Vauxhall Cresta , a tradition that ended with the introduction of the new PC Vauxhalls. The Velox name was discontinued at that time in favour of the more upmarket Vauxhall Cresta name, while

The engine balance characteristics of a straight-six engine compare favorably with the more common straight-four engines and V6 engines , which experience significant secondary dynamic imbalance, resulting in engine vibration. As engine reciprocating forces increase with
1463-464: Is the German brand BMW , which has always used a straight-six layout for its six-cylinder engines. Since 2017, the trend of switching to V6 engines has reversed due to the ability to create a modular engine family of straight engines sharing many components. Examples include the 2017–present Mercedes-Benz M256 engine , the 2019–present Jaguar Land Rover Ingenium engines (AJ300 and AJ300D versions),
1540-570: The BMW M337 (produced until 1958). Production of straight-six engines resumed in 1968 with the BMW M30 single overhead camshaft engine, built for 27 years and used in various models. The 1978–1989 BMW M88 engine was a double overhead camshaft design that was introduced in the BMW M1 mid-engine sport car. BMW's introduction of turbocharged straight-six engines (aside from the low-volume variants of
1617-508: The Duramax Straight-6 turbocharged diesel engine has been available in several General Motors SUV and light truck models since 2020. On March 25, 2022, Stellantis announced their new turbocharged straight-six engine, called Hurricane. Two outputs are available, a standard 400 or 500 hp (298 or 373 kW; 406 or 507 PS) high performance rated at 450 or 475 pound force-feet (610 or 644 N⋅m) of torque. The turbos on

The Ford 300 cu in (4.9 L) version of the straight-six engine was built from 1965 until 1996, with notable uses in trucks, SUVs, and vans. However, Ford straight-sixes were replaced by V6 engines in passenger cars during the mid-1970s. In 1908, the Oldsmobile Model Z was powered by a flathead straight-six petrol engine, which was produced until 1912 (in
1771-674: The Ford Falcon large sedan was introduced with a locally-built version of the American Ford Straight-6 overhead valve engine. In 1998, these engines were upgraded to a single overhead camshaft design. This was followed in 2002 by the Ford Barra dual overhead camshaft engine in 2002, which was produced in both naturally aspirated and turbocharged versions. The Ford Barra engine remained in use until Ford Australia ceased local production in 2016. The Chrysler Valiant
1848-686: The Mercedes-Benz M180 overhead camshaft engine. In 1985, the Mercedes-Benz OM603 3.0 L diesel straight-six engine was introduced. In 1996, the company replaced its petrol straight-sixes with a series of V6 engines, although it continued producing diesel straight-six engines. Production of petrol straight-six engines resumed in 2017 with the introduction of the Mercedes-Benz M256 turbocharged DOHC engine. Opel began production of straight-six engines in 1927 with
1925-659: The Nissan Cedric Special 50 luxury car. Using a similar design, the Nissan H30 engine was used in several luxury cars from 1965 through 1989. In 1966, Nissan began production of the six-cylinder versions of the Nissan L single overhead camshaft engine, which was produced until 2009. The 1985–2004 Nissan RB engine , used in the Nissan Skyline and several other cars, was produced in single overhead camshaft and dual overhead camshaft configurations until

The later generations of
2156-536: The Oldsmobile Straight-6 also used a flathead design from its introduction in the 1923 Oldsmobile Model 30 luxury car until it was replaced in 1950 by Oldsmobile's V8 engine. The 1913–1929 Oakland Six luxury car was powered by a flathead petrol engine produced in displacements of 177 cu in (2.9 L) and 334 cu in (5.5 L). In 1926, the Pontiac Six was introduced as
2233-675: The 1938 Jaguar 3½ Litre sports saloon/coupe and the 1948 Jaguar Mark V luxury car. The 1927 Rover Two-litre luxury car introduced the company's IOE straight-six petrol engine. This engine was used in various Rover models until the Rover P5 was discontinued in 1973, and in various Land Rover models from the 1961 Land Rover Series IIA until 1980 Land Rover Series III . The 1928 Austin 20/6 luxury car introduced Austin's flathead straight-six petrol engine. The 1938-1939 Austin Twenty-Eight used an enlarged version of this engine. This
2310-459: The 1998–2006 Volvo S80 ) used the uncommon design of a transversely-mounted straight-six engine. Production of Volvo straight-six engines ceased in 2015. BMW's first product was the 1917 BMW IIIa straight-six aircraft engine. The company began production of automotive straight-six engines in 1933 with the BMW M78 petrol engine, a 1.2 L overhead valve design that evolved over the years into

Still, all of them have a rocking imbalance that may or may not require a balance shaft, depending on the application. The six pistons with six unique phases cannot be "paired" as in the four-stroke case. The Detroit engines used a configuration that, once the primary rocking couple
2618-629: The Dutch Spyker 60 HP racing car in 1903. Straight-six engines increased in popularity in the years after and by 1909, approximately 80 manufacturers were using them (including 62 in the United Kingdom). Prior to the 1950s, V6 engines were rarely used, due to the poorer engine balance of V6 engines compared to straight-six engines. Since the 1980s, however, the shorter length of V6 engines has seen most manufacturers replace straight-six engines with V6 engines. An exception to this trend
2695-600: The GM plant in Petone, near Wellington. The LBP model ID was applied to "chassis only" exports to Australia, where local production included a two-door Caleche tourer and, in early four-door saloons, a unique "six-light" body featuring an additional rear window behind the back doors. This gave the car more resemblance from the rear to the pre-war designed J-series Vauxhall Fourteen it replaced (see accompanying illustration below). Velox LIP production also took place in Switzerland, where
2772-490: The General Motors New Zealand plant in Petone with special versions again built for local traffic police. PA five-door estate models, converted by Friary of Basingstoke, were also available. In their 1961–62 forms, the Velox and its Cresta sibling continued without further significant changes until replaced towards the end of 1962. For 1962, the painted dashboard gave way to simulated wood, the ashtray

A car tested by The Motor magazine in 1949 had a top speed of 74.1 mph (119.3 km/h) and could accelerate from 0–60 mph (97 km/h) in 22.8 seconds. A fuel consumption of 22.3 miles per imperial gallon (12.7 L/100 km; 18.6 mpg ‑US ) was recorded. The test car cost £550 including taxes. As well as being built at Vauxhall's Luton plant in England, early Velox and Wyvern models were assembled in Australia (by Holden in Melbourne) and in New Zealand at
3311-735: The Wyvern model. Technically, however, there were no further changes until the arrival of a completely new Velox in October 1957. In Australia, Holden built a quantity of utilities (pickup trucks) as well as the 2-door Vagabond Convertible based on the EIP Velox. These had a separate chassis - prefixed EBP - with the Australian bodies fitted to them. The Velox was also assembled at the General Motors New Zealand plant in Petone , north of Wellington, through to and including
3388-530: The benchmark Ford Zephyr with which it competed in the UK. Taking its cues from the Victor FB introduced the previous year (and sharing the doors of the smaller car), the new car was stylistically more restrained than its flamboyant predecessor, the removal of vertical fins emphasizing the car's width. Power output was increased to 115 bhp (86 kW). In October 1964 the Velox PB became available with
3465-419: The cube of piston bore, the straight-six is a preferred configuration for large truck engines. An even-firing six-cylinder two-stroke engine requires ignitions at 60° intervals, or else it would run with simultaneous ignitions and be no smoother than a triple in power delivery. As such, it also requires crank throws at 60° – . Such designs appear to have been limited to diesel engines such as
3542-580: The development pipeline for several years. This provided either 64 bhp (48 kW) or, with a compression ratio improved to 7.6:1, 68 bhp (51 kW) of power. A further test in 1952 by The Motor magazine of the EIPV with the short-stroke 2262 cc engine, found the top speed had increased to 80.4 mph (129.4 km/h) and acceleration from 0–60 mph (97 km/h) to 21.4 seconds. A similar fuel consumption of 23.6 miles per imperial gallon (12.0 L/100 km; 19.7 mpg ‑US )
3619-427: The front grill was enlarged and the three-piece rear window was replaced by a single wrap-around window. Technical improvements had to await the 1960 facelift, however. The October 1960 facelift for 1961 was marked by further modifications to the trim, new rear lights with modified tail fins (no longer with indicators built in), combined front park/indicator lamps and a new dashboard with the two round dials replaced by
3696-480: The inside the new Velox also followed US practice of combining a front bench seat with a column-shift gear lever, continuing a trend that dates back to the first Velox models of 1948. Velox models were also assembled at the General Motors Holden plants throughout Australia, and the General Motors New Zealand plant in Petone, north of Wellington. The Wyvern was replaced by the new Victor model line which

PB Velox models were again assembled at the General Motors New Zealand plant in Petone and special versions were again built for local traffic police. The 3.3 was particularly popular with these government customers. October 1965 saw the introduction of the Vauxhall Cresta PC, equipped with that same 3294 cc engine. This time no Velox version
3850-441: The straight-six can be scaled up to substantial sizes for heavy trucks, locomotives, industrial and marine use. If an appropriate firing order is used, a straight-six engine has perfect primary and secondary engine balance . The primary balance is due to the front and rear trio of cylinders moving in pairs (albeit 360° out of phase), thus canceling out the rocking motion present in a straight-three engine . The secondary balance
3927-487: Was a new front grille and trafficators were replaced by flashing lights (red at the rear, US-style). More important was the introduction at this time of a sister model, branded as the Vauxhall Cresta . In addition to superior equipment levels, the Cresta was distinguished by a two tone paint finish. The 1954 VELOX also differed from the 1953 which had a side opening bonnet, by having a front opening bonnet Detroit

#17327906667414004-486: Was again shared with the 4-cylinder -engined Wyvern. The car was launched with the previous model's engine but with power output increased to 58 bhp (43 kW). A car with the original 2275 cc engine tested by The Motor magazine in 1951 had a top speed of 77.4 mph (124.6 km/h) and could accelerate from 0-60 mph (97 km/h) in 23.7 seconds. A fuel consumption of 23.5 miles per imperial gallon (12.0 L/100 km; 19.6 mpg ‑US )
4081-493: Was also built in the New Zealand plant. Specially engineered versions of the Velox were built for use by the NZ Traffic Police. Minor modifications to the car's six-cylinder engine raised power output to 83 bhp (61 kW). As before, the Cresta was distinguished from the Velox model by superior levels of equipment and also a two-tone paint finish. The Velox PA received its first facelift in October 1959 when

The 1948–1959 Lagonda straight-6 dual overhead camshaft petrol engine was used in various Aston Martin and Lagonda cars. This engine's successor was the Tadek Marek-designed straight-six used in the DB4 (1958), DB5 (1963), DB6 (1965) and DBS (1967). The Ford Zephyr 6 overhead valve engine
4543-412: Was followed by the 1962–1988 Chevrolet Turbo-Thrift engine (also using an overhead valve design), which was replaced by various General Motors V6 engines. The 1952 through 2006 AMC Straight-6 petrol engine initially used a flathead design before being upgraded to an overhead valve design in 1956. A new I6 design with a short stroke and seven main bearing crankshaft was introduced in 1964. The engine
