you could use 4 engines that drive one each wheel and they are battery powered because in drifting the more engines you have = more powahh = more smokahh = more *cough* epicfail *cough*
since electric cars make lots of torques you could make a blackhole in a drift server and make those Big L's dissapear 4 eva !
Engine location wouldn't really matter, what's important is weight ditribution, more weight to the rear and your rear end is all over the place, less weight on the rear, and your tires will spin easily, bu it wil be harder to control..
before christmas it snowed here .. and i have a road bike ( u kno... like tour de france ) and i was really bored... so guess what ? i invented a new winter dicipline for the x-games
nah ... i dont have a half pipe near my house so i didnt try that.... it was more of a rally stage in a snowy road with a road bike .... it was scary.... and i learnt how to apply more torque and have more grip in slippery surfaces
For drifting the best is front engine and rearwheel drive. When the engine is at the front, the weight is away from the rearwheels making them easier to lose grip and causing oversteer. And the rearwheel drive adds to making it easier of losing grip at the rearwheels which is what you want to make the rear slide. I have drifted alot in real life, and the easiest way to get into a slide and hold it I found in BMW's and Ford Granadas and other cars who have the engine at the front and rearwheel drive.
