Rear-wheel Drive
Rear-wheel drive (RWD) is a form of engine and transmission layout used in motor vehicles, in which the engine drives the rear wheels only. Until the late 20th century, rear-wheel drive was the most common configuration for cars. Most rear-wheel drive vehicles feature a longitudinally-mounted engine at the front of the car. Layout The most common layout for a rear-wheel drive car is with the engine and transmission at the front of the car, mounted longitudinally. Other layouts of rear-wheel drive cars include front-mid engine, rear-mid engine, and rear-engine. Some manufacturers, such as Alfa Romeo, Lancia, Porsche (944, 924, 928) and Chevrolet (C5, C6, and C7 Corvettes), place the engine at the front of the car and the transmission at the rear of the car, in order to provide a more balanced weight distribution. This configuration is often referred to as a transaxle since the transmission and axle are one unit. History 1890s to 1960s Many of the cars built in the 19t ...

Compact Car
Compact car is a vehicle size class — predominantly used in North America — that sits between subcompact cars and mid-size cars. "Small family car" is a British term and a part of the C-segment in the European car classification. However, prior to the downsizing of the United States car industry in the 1970s and 1980s, larger vehicles with wheelbases up to were considered "compact cars" in the United States. In Japan, small size passenger vehicle is a registration category that sits between kei cars and regular cars, based on overall size and engine displacement limits.

Automobile Platform
A car platform is a shared set of common design, engineering, and production efforts, as well as major components, over a number of outwardly distinct models and even types of cars, often from different, but somewhat related, marques. It is practiced in the automotive industry to reduce the costs associated with the development of products by basing those products on a smaller number of platforms. This further allows companies to create distinct models from a design perspective on similar underpinnings. A car platform is not to be confused with a platform chassis, although such a chassis can be part of an automobile’s design platform, as noted below. Definition and benefits A basic definition of a platform in cars, from a technical point of view, includes: underbody and suspensions (with axles) — where the underbody is made of front floor, Rearfloor, engine compartment and frame (reinforcement of underbody). Key mechanical components that define an automobile platform includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Front-wheel Drive
Front-wheel drive (FWD) is a form of engine and transmission layout used in motor vehicles, where the engine drives the front wheels only.

Other layouts of front-wheel drive that have been occasionally produced are a front-engine mounted longitudinally, a mid-engine layout and a rear-engine layout. History Prior to 1900 Experiments with front-wheel drive cars date to the early days of the automobile. The world's first self-propelled vehicle, Nicolas-Joseph Cugnot's 1769/1770 "fardier à vapeur", was a front-wheel driven three-wheeled steam-tractor.

Oldsmobile 88
The Oldsmobile 88 (marketed from 1989 on as the Eighty Eight) is a full-size car that was sold and produced by Oldsmobile from 1949 until 1999. From 1950 until 1974, the 88 was the division's most profitable line, particularly the entry level models such as the 88 and Dynamic 88. The 88 series was also an image leader for Oldsmobile, particularly in the early years (1949–51), when it was one of the best performing automobiles, thanks to its relatively small size, light weight, and advanced overhead-valve high-compression V8 engine. This engine, originally designed for the larger C-bodied and more luxurious 98 series, also replaced the straight-8 on the smaller B-bodied 78. With the large, high performance V8, the Oldsmobile 88 is considered by some to be the first muscle car, although this title is disputed. Naming conventions used by GM since the 1910s for all divisions used alphanumeric designations that changed every year. Oldsmobile starting after the war changed their d ...

GM H Platform (RWD)
The General Motors H platform (or H-body) is an automobile platform used by subcompact cars from the 1971 to 1980 model years. The first subcompact car design developed by GM, the rear-wheel drive H platform initially underpinned the Chevrolet Vega and its Pontiac Astre counterpart. For 1975, the H platform was expanded from entry-level vehicles to sport compacts, adding the Chevrolet Monza, Buick Skyhawk, Oldsmobile Starfire, and Pontiac Sunbird. In contrast to the globally-developed T platform (later sold alongside it), the H-platform was sold nearly exclusively in North America. Following the downsizing of its larger car lines (the B-body full-size, A-body intermediate, E-body personal luxury), GM moved to redesign the rest of its major model lines. Following the 1980 shift of the X-body compacts to front-wheel drive, the H platform ended production for the 1980 model year. For 1982, the H-body vehicles were replaced by the front-wheel drive J-body; while again s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
