The Tucker 48, commonly but incorrectly referred to as the Tucker Torpedo, was an automobile conceived by Preston Tucker while in Ypsilanti, Michigan, and briefly produced in Chicago, Illinois, in 1948. Only 51 cars were made including their prototype before the company was forced to declare bankruptcy and cease all operations on March 3, 1949, due to negative publicity initiated by the news media, a Securities and Exchange Commission investigation, and a heavily publicized stock fraud trial. Tucker suspected that the Big Three automakers and Michigan Senator Homer S. Ferguson had a role in the Tucker Corporation's demise.
The unsprung mass of a vehicle is the mass of the suspension, wheels or tracks, and other components directly connected to them. This contrasts with the sprung mass supported by the suspension, which includes the body and other components within or attached to it. Components of the unsprung mass include the wheel axles, wheel bearings, wheel hubs, tires, and a portion of the weight of driveshafts, springs, shock absorbers, and suspension links. Brakes that are mounted inboard are part of a vehicle's sprung mass.
The Chevrolet Corvair is a rear-engined, air-cooled compact car manufactured by Chevrolet in two generations between 1960–1969. A response to the Volkswagen Beetle, it was produced in 4-door sedan, 2-door coupe, convertible, 4-door station wagon, passenger van, commercial van, and pickup truck body styles in its first generation (1960–1964), and as a 2-door coupe, convertible or 4-door hardtop in its second (1965–1969). Total production was approximately 1.8 million vehicles from 1960 until 1969.
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different.
A four-wheel drive, also called 4×4 or 4WD, is a two-axled vehicle drivetrain capable of providing torque to all of its wheels simultaneously. It may be full-time or on-demand, and is typically linked via a transfer case providing an additional output drive shaft and, in many instances, additional gear ranges.
The Porsche 804 is a single-seat, open-wheeled racing car produced by Porsche to compete in Formula One (F1). It raced for a single season in 1962 in the 1½ litre formula.
Front-wheel drive (FWD) is a form of engine and transmission layout used in motor vehicles, in which the engine drives the front wheels only. Most modern front-wheel-drive vehicles feature a transverse engine, rather than the conventional longitudinal engine arrangement generally found in rear-wheel-drive and four-wheel-drive vehicles.
In automotive design, an RR, or rear-engine, rear-wheel-drive layout places both the engine and drive wheels at the rear of the vehicle. In contrast to the RMR layout, the center of mass of the engine is between the rear axle and the rear bumper. Although very common in transit buses and coaches due to the elimination of the drive shaft with low-floor buses, this layout has become increasingly rare in passenger cars.
A truggy is a type of high performance off-road racing vehicle that combines features from two older existing categories of off-road racing vehicles, trucks and buggies. The first truggies were built for racing in the SCORE and BITD off-road desert racing series, held in Mexico, California, Nevada and Arizona.
A drive shaft, driveshaft, driving shaft, tailshaft, propeller shaft, or Cardan shaft is a component for transmitting mechanical power, torque, and rotation, usually used to connect other components of a drivetrain that cannot be connected directly because of distance or the need to allow for relative movement between them.
Bendix Corporation is an American manufacturing and engineering company which, during various times in its existence, made automotive brake shoes and systems, vacuum tubes, aircraft brakes, aeronautical hydraulics and electric power systems, avionics, aircraft and automobile fuel control systems, radios, televisions and computers.
A torque tube system is a power transmission and braking technology that involves a stationary housing around the drive shaft, often used in automobiles with a front engine and rear drive. The torque tube consists of a large diameter stationary housing between the transmission and rear end that fully encloses a rotating tubular steel or small-diameter solid drive shaft that transmits the power of the engine to a regular or limited-slip differential. The purpose of a torque tube is to hold the rear end in place during acceleration and braking. Otherwise, the axle housing would suffer axle wrap, which is when the front of the differential lifts excessively during acceleration and drops down during braking. Its use is not as widespread in modern automobiles as is the Hotchkiss drive, which holds the rear end in place and prevents it from flipping up or down, during acceleration and braking by anchoring the axle housings to the leaf springs using spring perches.
The Panhard Dyna Z is a lightweight motor car produced by Panhard of France from 1954 to 1959. It was first presented to the press at a Paris restaurant named Les Ambassadeurs on 17 June 1953 and entered production the following year. In 1959, it was replaced by the Panhard PL 17.
The Subaru 1000 is a car produced by the Japanese company Fuji Heavy Industries from 1966 to 1969. It was the first-and-only Subaru with front-wheel drive that was in the Japanese government "compact car" classification. Previous Subaru models such as the Subaru 360 and the Sambar had been rear-engined, rear-wheel drive kei cars.
The Chevrolet Engineering Research Vehicle (CERV) is a series of Chevrolet experimental cars. Chevrolet Staff engineer, designer, and race car driver Zora Arkus-Duntov started development of the CERV I in 1959, and began work on the CERV II in 1963. Chevrolet chief engineer Don Runkle and Lotus' Tony Rudd discussed creating a new show car to demonstrate their engineering expertise in 1985; It would become the CERV III. Corvette chief engineer Dave Hill unveiled the CERV IV in 1993, a test vehicle for the 1997 C5 Corvette.
The Nissan GT-R is a car built by Japanese marque Nissan since 2007. It has a 2+2 seating layout and is considered both a sports car and a grand tourer. The engine is front-mid mounted and drives all four wheels. It succeeds the Nissan Skyline GT-R, a high-performance variant of the Nissan Skyline. Although this model was the sixth-generation to bear the GT-R name, it is no longer part of the Skyline line-up. The car is built on the PM platform, derived from the FM platform used in the Skyline and Nissan Z models. Production is conducted in a shared production line at Nissan's Tochigi plant in Japan.
A rear-engine, front-wheel-drive layout is one in which the engine is between or behind the rear wheels, and drives the front wheels via a driveshaft, the complete reverse of a conventional front-engine, rear-wheel-drive vehicle layout.
Henri Perrot was a French engineer who was one of the pioneers of the automobile industry from the late nineteenth and early twentieth centuries. He holds numerous patents in the field of automotive drum/shoe braking.
The Citroën Traction Avant is the world's first monocoque-bodied, front-wheel drive car that was mass-produced. A range of mostly 4-door saloons and executive cars, as well as longer wheelbased "Commerciale", and three row seating "Familiale" models, were produced with four- and six-cylinder engines, by French carmaker Citroën from 1934 to 1957. With some 760,000 units built, the Traction Avants were the first front-wheel drives made in such (six-figure) quantity.
The GinettaG15 is a two-seater, rear-engined sports car designed by Ivor Walklett and built by Ginetta Cars Limited in Witham, Essex between 1968 and 1974.
