Bugatti Type 46

Last updated January 24, 2024

The Bugatti Type 46 and later Type 50 were large enclosed touring cars and along with the Type 50B racing version, were all produced in the 1930s. Their relative ubiquity and numbers, combined with their styling caused them to sometimes receive the appellation of being a Molsheim Buick.^{[ citation needed ]}

Type 46

The Type 46 used a 5.4 L (5359 cc/327 in³) straight-8 engine with 3 valves per cylinder driven by a single overhead camshaft. Power was reported at 140 hp (104 kW). The engine was undersquare like most Bugatti designs with an 81 mm bore and 130 mm stroke.

The Type 46 was a large car, weighing 2500 lb (1134 kg) and riding on a 138 in (3505 mm) wheelbase. 400 examples were produced from the end of 1929 through 1936. The three speed gearbox was in unit with the live rear axle, resulting in high unsprung weight, and a relatively harsh ride. Despite this, the model was a favourite of Le Patron, and it remained in production longer than might have been expected

Type 46S

A supercharged version, the Type 46S, was introduced in 1930. With just 160 hp (119 kW), from its Rootes-type blower, it was not a great success. 18 supercharged cars were made in all.

Type 50

The Type 50 was a sporting coupe version of the Type 46. It rode on a shorter wheelbase, 122 in (3099 mm), and used a smaller 5.0 L (4972 cc/303 in³) version of the engine. This engine had squarer dimensions, however, at 86 by 107 mm, and twin camshafts actuated two valves per cylinder. Power output was impressive at 225 hp (167 kW). Many cars had landaulet roofs and Bugatti-style two-tone paint.

Type 50T

The Type 50 Touring was a sedan version of the Type 50. It used the same 138 in (3505 mm) wheelbase as its predecessor, the Type 46, but shared the 5.0 L engine of the Type 50. The engine was tuned for torque, though, with just 200 hp (149 kW) on tap. In total, 65 Type 50 and Type 50T Bugattis were produced between 1930 and 1934.

Type 50B

A racing version, the Type 50B, was also produced. It shared the 5.0 L 2-valve engine but was blown to produce 470 hp (350 kW). It was used from 1937 through 1939. A pair of these engines were installed in the Bugatti P100 airplane, with specially cast magnesium crankcases.

The GM Ecotec engine, also known by its codename L850, is a family of all-aluminium inline-four engines, displacing between 1.4 and 2.5 litres. Confusingly, the Ecotec name was also applied to the final DOHC derivatives of the previous GM Family II engine; the architecture was substantially re-engineered for this new Ecotec application produced since 2000. This engine family replaced the GM Family II engine, the GM 122 engine, the Saab H engine, and the Quad 4 engine. It is manufactured in multiple locations, to include Spring Hill Manufacturing, in Spring Hill, Tennessee, with engine blocks and cylinder heads cast at Saginaw Metal Casting Operations in Saginaw, Michigan.

The Ford Modular engine is Ford Motor Company's overhead camshaft (OHC) V8 and V10 gasoline-powered small block engine family. Introduced in 1990, the engine family received its “modular” designation by Ford for its new approach to the setup of tooling and casting stations in the Windsor and Romeo engine manufacturing plants.

The Jaguar AJ-8 is a compact DOHC V8 piston engine used in many Jaguar vehicles. It was the fourth new engine type in the history of the company. It was an in house design with work beginning before Ford's purchase of the company. In 1997 it replaced both designs previously available on Jaguar cars: the straight-6 Jaguar AJ6 engine, and the Jaguar V12 engine. It remained the only engine type available on Jaguar until 1999 with the launch of the S-Type, when the Jaguar AJ-V6 engine was added to the list. The AJ-V8 is available in displacements ranging from 3.2L to 5.0L, and a supercharged version is also produced. Ford Motor Company also used this engine in other cars, including the Lincoln LS and the 2002–2005 Ford Thunderbird, as well as in several Land Rovers, and the Aston Martin V8 Vantage.

Most road cars used an eight-valve engine, though five Type 13 racers had 16-valve heads, some of the first ever produced. The road cars became known as pur-sang ("thoroughbred") in keeping with Ettore Bugatti's feelings for his designs.

The Bugatti Type 35 is an iconic race car design produced by Bugatti at their Molsheim premises between 1924 and 1930. It was extremely successful when raced by the factory works team. It was also bought by a diverse roster of privateer clientele from around the world. It pioneered the concept of a holistically conceived, race-ready car available for purchase.

The Bugatti Type 51 series succeeded the famous Type 35 as Bugatti's premier racing car for the 1930s. The main distinction is that it uses a twin cam engine. Unlike the dominant Type 35s of the prior decade, the Type 51 were unable to compete with the government-supported German and Italian offerings.

The Bugatti Type 55 is a sports car produced by Bugatti from 1932 to 1935. It is a road-going version of the Type 51 Grand Prix car. A roadster, it had a 108.3 in (2750 mm) wheelbase and 1800 lb (816 kg) weight.

The Douvrin engine is also referred to as the ZDJ/ZEJ engine by Peugeot, and as the J-type engine by Renault.

The Bentley 3 Litre was a car chassis manufactured by Bentley. The company's first, it was developed from 1919 and made available to customers' coachbuilders from 1921 to 1929. The Bentley was very much larger than the 1368 cc Bugattis that dominated racing at the time, but double the size of engine and strength compensated for the extra weight. The 4000 lb (1800 kg) car won the 24 Hours of Le Mans in 1924, with drivers John Duff and Frank Clement, and again in 1927, this time in Super Sports form, with drivers S. C. H. "Sammy" Davis and Dudley Benjafield. Its weight, size, and speed prompted Ettore Bugatti to call it "the fastest lorry in the world", which was regarded as a compliment. Built in 3 main variants, Blue label, Red Label Speed models all carrying a 5-year warranty, and the coveted and rare Green Label 100 mph cars, which only carried a 12-month warranty reflecting the high state of tune.

The first DOHC version was in the 1993 Alfa Romeo 164, with an aluminium alloy engine block and head with sodium filled exhaust valves.
