  FF - Front Engine Front Drive
  The engine and the drive wheels are at the front of the car. FF vehicles are fairly easy to drive, but do not generally handle high horsepower outputs very well. This type of vehicle tends to understeer, meaning that they take a lot of effort to turn.

  FR - Front Engine Rear Drive
  The engine is in the front of the vehicle, but the rear wheels are the drive wheels. This type of car has a great tendency for oversteering, and throttle management is very important when exiting corners to try to prevent the oversteer condition. NASCAR uses FR vehicles.

  4WD - 4 Wheel Drive
  All four wheels are drive wheels. In many forms of auto racing, 4WD vehicles are banned due to the inherent advantage of using all four wheels as drive wheels (due to the added traction advantage).

  MR - Midship Engine Rear Drive
  The engine is located between the axles (usually just behind the driver), and the rear wheels are the drive wheels. This type of car can be a bit tricky to drive. Typical MR cars are those used in F1, CART, and IRL. In open-wheel cars (such as those in the aforementioned racing series), there is extremely little material to absorb the shock of a front-end collision in an accident, thus providing fairly little protection for the driver (especially the driver's legs); it is truly amazing that there are not more driver injuries in open-wheel cars with MR drivetrains due to this 'non-protection' issue.
