Originally posted by tranceporter View PostGet a car with over 300 lb-ft torque, and try launching it from standstill. The 4WD will take it without flinching, the rwd might slide it's rear end a bit depending on the state of tyres, and the road conditions. The FWD will then start showing signs of torque steer. You will feel like you have to grip the steering wheel tightly, otherwise the front wheels will make it wobble. It's true that many modern FWD cars come with factory fitted LSD, but that helps more in cornering and keeping traction when you come out of tight bends. Essentially, LSD allows 2 wheels to spin at different speeds, which helps on twisty roads.
The drift boys tend to use a welded diff on their (RWD) cars for maximum drift fun but (as said) this can cause terminal understeer in the wet.
Whereas, the rally boys () will use a proper LSD (aka slipper) to allow them to get the maximum power down on varying road surfaces and conditions.
The original type of LSD uses clutch plates internal to the diff to determine the amount of slip and is still the preferred type for most RWD applications. Later types such as ATB (automatic torque biasing) and Gripper diffs can provide better characteristics for FWD cars, although the choice is often down to your preferred driving style.

Originally posted by Dark Black View PostErrr.. no, a normal diff does that, without which you'd tend to plough straight on in tight corners, especially in the wet. An LSD actually works to prevent some of the wheel spin in order to allow more power to be transmitted through the tyres. How much depends on how tight the slipper is set up.

Originally posted by tranceporter View PostYeah. Some cars have permanent 4WD AFAIK. Case in point, a Subbie Impreza.
