The simplistic design works acceptably well for 2WD vehicles.
420 BHP, four wheel drive, cool looks: Kickass car!
Movie shows 2 boring accelerations producing the gentle grrrrrr!
4WD vehicles may also be more likely to be driven on surfaces with reduced traction.
With a 4×2, engine power is transmitted to only two wheels, usually the rear.
Tallant’s Hot Rod Shop (www.tallantsauto.net) builds a bad boy Cadi powered by a 572 big block. Front wheel drive converted to rear wheel drive with OD Trans, 9 inch Ford Rear End, 4 link, etc… this ain’t your Grandpa’s Cadillac !
The term four-wheel drive describes truck-like vehicles that require the driver to manually switch between two-wheel drive mode for streets and four-wheel drive mode for low traction conditions such as ice, mud, snow, slippery surfaces, or loose gravel.
This problem can happen in both 2WD and 4WD vehicles, whenever a driven wheel is placed on a surface with little traction or raised off the ground.
900hp+ Golf, 4 wheel drive
A differential allows one input shaft to drive two output shafts with different speeds.

All-wheel drive AWD is often used to describe a full time 4WD that may be used on dry pavement without destroying the drivetrain, although the term may be abused when marketing a vehicle.
Full-Time 4WD can be disengaged and the center differential can be locked, essentially turning it into regular 4WD. On the other hand, AWD cannot be disengaged and the center differential cannot be locked.
My buddy’s from Epic Tuning …As some of you remember we had a ’91 EF hatch with a stock Z6 engine making 375whp @ 24psi. At this power level it ran 11.41 @121MPH. Since then we had turned it up some more. It made 390WHP with a slipping clutch @26psi. We changed the clutch and ran it at the track @ 28-30psi. The car ran 11.3@127mph. We couldn’t run anymore because the car had no roll cage. Instead of turning it into a drag car we and the owner decided to go in a different direction. We wanted to make it all wheel drive, work through the problems and have a reliable 4WD civic for the street. We converted the car to Real Time 4WD from a ’89 Civic Wagovan. We used the transmission, axles, driveshaft, viscous coupling, rear differential and subframe. The clutch is a ACT 4 pad disc and Heavy Duty pressure plate. So far at 24psi the drivetrain is holding up great. We have a couple hundred miles and 40+ tire chirping launches without a problem. We will keep putting it through its paces and see what, if anything, breaks. We will have video up shorty along with new all wheel dyno numbers. check out the car at http://www.honda-tech.com/zerothread?id=2104408&page=1
Such a design handles well.
