FWD? What is it? • FWD which is known as front wheel drive is the most common type of engine layout currently used within cars now. The engine uses the front wheels as the ones to drive the vehicle. Nowadays, most front wheel drive vehicles today feature transverse engine mounting.
RWD? What is it? • RWD which is known as rear wheel drive was a common engine layout used in cars during the 20th century. Most RWD cars place the engine at the front of the vehicle but there are also times when it is placed in the midsection or the rear. RWD uses the rear wheels to drive using a driveshaft linked between the rear axles.
