We are all familiar with these terms which usually been used to describe how car distribute engine torque on wheels. But sometimes we confuse these terms with each other so I would like to explain them a little.
FWD(Front Wheel Drive): This is most popular type which is use in so many cars. In these kind of vehicles, front wheel actively work with engine and spin all of the time. Rear wheels have no effect on car traction or movement. The reason which makes FWD so popular is that it's cheap to design and produce and less parts need to be used so as result it comes with economical solution. Worst thing about FWD is that when car trying to have heavy turn with high speed car respond weakly and does not stay in line properly. Majority of Asian and French cars are FWD. So when you see a FWD car you can be sure you economical car which has nothing to do with performance.
RWD(Rear Wheel Drive): Unlike FWD, RWD distribute torque on rear wheels. This has benefit that traction would be done by front wheel and straight line movement will be done by rear wheels which this gives more specific and precise handling in compare with FWD. Anyway depend on engine position there is possibility of loss force from engine to wheels which this happens when engine has been placed in front. That's one of the reason that sport rear wheel drive cars like Porsche or Ferrari put their engine at the back to minimise lost of torque to wheels. Generally German cars and American cars are produced RWD.
4WD(4-Wheel Drive): Engine torque will always send to rear wheels and depend on choice of driver it can be send to front wheel or not. This is gives a balance between fuel economy of the car and traction ability and mostly been used in SUV and 4X4 cars. Usually in these kind of cars driver has option to choose whether engage front wheel in movement or not but he can't choose only front wheel to have movement.
AWD(All Wheel Drive): Engine power would be distritbute to all wheels all the time. This is a little confusing as diffrent companies using diffrent strategies and methodes to distribute power on wheels. But no matter how power distributed on wheels, it's always come up with best traction possiblity for car and great stability. Many great quality cars Audi R8 or Lamborghini using this type of traction. Generally when you see a car is AWD you can count on the performance and handling of car.
