NationMaster - Encyclopedia: MF layout

In automobile design, an MF or Mid-engine, Front wheel drive layout is one in which the front wheels are driven by an engine placed just behind them, in front of the passenger compartment. In contrast to the front-engined FF layout the center of gravity of the engine is behind the front axle. This layout is typically chosen for its better weight distribution (the heaviest component is near the center of the car, lowering its moment of inertia).

The mid-engined layout does, however, use up central space, making the resulting vehicle rather long. This may be why no manufacturer currently offers the MF layout.

Traditionally, the term mid-engine has been reserved for cars that place the engine and transaxle behind the driver and in front of the rear axles, as in the Lamborghini Countach or Ferrari Testarossa, but an engine placed in front of the driver's compartment but fully behind the front axle line also qualifies as mid-engine.
