FF layout
In Automobile design, an FF, or Front-engine, Front wheel drive, layout places both the engine and drive wheels at the front of the vehicle. This layout is typically chosen for its compact packaging - that is, it takes up very little space, allowing the rest of the vehicle to be designed more flexibly. In contrast with the FR layout, the FF layout eliminates the central tunnel to accomodate a driveshaft to the rear wheels. Like the RR and MR layouts, it places the heavy engine over the drive wheels to aid in traction. However, since the front wheels almost always handle steering, the FF layout compromises traction while turning.
Early cars using the FF layout include the Citroën Traction Avant and the Mini. In the 1980s, the traction and packaging advantages of this layout caused almost all vehicles, apart from sports cars to adopt it.
