All Wheel Drive sistem on the cars does it have an option to swich to front wheel drive?or rear?
which is the better traction rear wheel drive or front?and 4x4 they can be swiched to front or rear drive?

No most vehicles that are all wheel drive use their differential's to deliver power where it need to be when is required automatically. Some are based on mechanics and others on pre programed computer settings. Do they have the option to switch from front to rear, sure since only one set of wheels usually has the ability to have full power. Now this will depend on weather the vehicle is a front wheel drive with a rear drive differential case or Rear wheel drive with front wheel drive differential case. Most large Vehicles are Rear drive with a front wheel drive differential case. Smaller vehicles are front wheel drive with a rear differential case, not only because is cheaper to make but is much more compact so they can sit lower to the ground(this is done because is cheaper to use only one platform for all trims rather than having a specific platform for a rear drive front wheel differential case vehicle) As to which has better traction, is always a rear wheel drive vehicle of course,but when it comes to dynamics rather than traction alone a front wheel drive vehicle is easier to maneuver by inexperience drivers. A rear wheel drive vehicle will reach it's maximum torque band before any front wheel vehicle even if they are identical, just because the rear drive will remain inline but a front wheel drive even with computer control will slightly move side to side losing traction for small instants hence delaying it's full power. A 4x4 system is completely different to an all wheel drive system. A 4X4 has two shafts and no differential case, rather two complete transmissions, so it can deliver full power to all wheel at all times. A true 4X4 could never go over 20km an hour(well unless it was design to do so but that is a more specialized vehicle say a MONSTER TRUCK where some have two independent transmission to run the front and rear wheels), because it would not only wear down the tires, be hard to steer, but because it is delivering the same power to all wheels at the same time. There are vehicles that are all wheel drive and have the option of been 4x4 but in reality they are 3 wheel vehicles since only one of either the front of the rear depending on where the transfer case is located will deliver the same power as the other two wheels at one time. Because they are set to only be driven slow the change from one to the other wheel is not noticeable since it only activates when looss of traction is detected. True 4x4 with all wheel drive are very expensive and you will notice the difference since you are paying for two transmission and a transfer case. As to their uses are very limited to those who use this vehicles off road, for road use even in winter unless the snow is as deep as the tires there is no need for a 4x4. I believe even having all wheel drive vehicles makes people believe they can drive at all speeds in the winter which makes it very dangerous for the rest of us. All wheel drive vehicles are great in slippery conditions, slightly better than a front wheel drive or a rear drive but they must be driven just as careful. Another down side to all wheel drive is Fuel they will cost more to operate, but a true 4x4 cost more due to it's weight.

The main idea of drifting is making the rear end of the car slide due to a loss of traction on the lateral direction. You can do that by braking hard (with the handbrake) or accelerating hard if you have a RWD car. Personally I don’t think a FWD can make really good drifts because with the brake your speed will decrease. RWD can still accelerate while sliding, thus making a longer slide through the entire corner. Try playing a game like need for speed underground with FWD and then RWD to live the difference.

you wish... 4 wheel drive = most control but less power. Fwd = decent control , decent power. Rwd = no control, more power. I know the skyline gtr has that awd launch to 90%rwd after certain mph... but those cars will probably cost u a pretty penny.
