Most engines with four or less cylinders use a straight engine layout, and most engines with eight cylinders or more use a V engine layout. However, there are various exceptions to this, such as the straight-eight engines used by various luxury cars from 1919-1954, [ 1 ] [ 2 ] [ 3 ] V4 engines used by some marine outboard motors, V-twin and ...
The front-engine, rear-wheel drive layout (abbreviated as FR layout) is one where the engine is located at the front of the vehicle and driven wheels are located at the rear. [3] This was the traditional automobile layout for most of the 20th century, and remains the most common layout for rear-wheel drive vehicles.
The engine positions of most pre–World-War-II cars are front-mid or on the front axle. This layout is the most traditional form and remains a popular, practical design. The engine, which takes up a great deal of space, is packaged in a location passengers and luggage typically would not use.
FR layout. A front-engine, rear-wheel-drive layout (FR), also called Systeme Panhard [1] is a powertrain layout with an engine in front and rear-wheel-drive, connected via a drive shaft. This arrangement, with the engine straddling the front axle, was the traditional automobile layout for most of the pre-1950s automotive mechanical projects. [2]
F4 layout. In automotive design, an F4, or front-engine, four-wheel drive (4WD) layout places the internal combustion engine at the front of the vehicle and drives all four roadwheels. This layout is typically chosen for better control on many surfaces, and is an important part of rally racing, as well as off-road driving. In terms of racing ...
The front-engine front-wheel-drive layout also has this advantage. Since the engine is typically the heaviest component of the car, putting it near the rear axle usually results in more weight over the rear axle than the front, commonly referred to as a rear weight bias. The farther back the engine, the greater the bias.
V engines typically have a shorter length than equivalent inline engines, however the trade-off is a larger width. V6, V8 and V12 engines are the most common layout for automobile engines with 6, 8 or 12 cylinders respectively.
The mechanical layout and packaging of an RMR car are substantially different from that of a front-engine or rear-engine car. When the engine is in front of the driver, but fully behind the front axle line, the layout is sometimes called a front mid-engine, rear-wheel-drive, or FMR layout instead of the less-specific term front-engine; and can ...
