The drive train and engine layout significantly influences the handling characteristics of an automobile, and is crucially important in the design of a sports car.
The front-engine, rear-wheel drive layout (FR) is common to sports cars of any era and has survived longer in sports cars than in mainstream automobiles. Examples include the Caterham 7, Mazda MX-5, and the Chevrolet Corvette.
In search of improved handling and weight distribution, other layouts are sometimes used. The RMR layout is commonly found only in sports cars — the motor is centre-mounted in the chassis (closer to and behind the driver), and powers only the rear wheels. Some high-performance sports car manufacturers, such as Ferrari and Lamborghini prefer this layout. Many modern cars, especially grand tourers, also use a FMR layout, with the motor sitting between the front axle and the firewall.
Porsche is one of the few, remaining manufacturers using the rear-engine, rear-wheel drive layout (RR). The motor's distributed weight across the wheels, in a Porsche 911, provides excellent traction, but is not ideal, as the engine's weight is not between the two axles; the vehicle is poorly balanced, thus, many early Porsches handled twitchily[citation needed]. Yet Porsche has continuously refined the design and in recent years combined engineering modifications and electronic driving aids (i.e. computerised traction-stability control) to counteract inherent design shortcomings.
Some sport cars have used the front-engine, front-wheel drive layout (FF), e.g. Fiat Barchetta, Saab Sonett and Berkeley cars. This layout is advantageous for small, light, lower power sports cars, as it avoids the extra weight, increased transmission power loss, and packaging problems of a long driveshaft and longitudinal engine of FR vehicles. Yet, its conservative handling effect, particularly understeer, and the fact that many drivers believe rear wheel drive is a more desirable layout for a sports car make this layout atypical to high-performance sports cars. The FF layout, however, is common in sport compacts and hot hatches, such as the Honda Civic Si/Type R and the Volkswagen Golf GTi, and cars in general (excepting sports cars).
Before the 1980s few sports cars used four-wheel drive, which had traditionally added a lot of weight. Although not a sports car, the Audi Quattro proved its worth in rallying. With its improvement in traction, particularly in adverse weather conditions, four-wheel drive is no longer uncommon in high-powered sports cars, e.g. Porsche, Lamborghini, and the Bugatti Veyron.
