i wish these car makers had an option for rwd, fwd, and awd in one car. imagine that :D:D. so many choices and options (even though its just three :P) but you know haha.

They could always make a awd with a knob on the dash that manually adjusts the % torque to the front/rear.

Ive always wondered why nobody has done that. it would be so useful. Beemer do almost have that but not quite. Cause a normal AWD car is actually FWD that might put some torque back after the front wheels have started loosing grip. Its called useles AWD, Volvos got it and most japanese Korean etc.

If the base car was a FWD car then it probably is a "useless" system (as you so cleverly described it). If the base car was RWD...welcome to the funzone!

Why an outdated TORSEN? Lexus couldn't package in a small Haldex unit that would handle all the tq? Or is this just a hacksaw job from the Hybrid? Either way, its good to see Lexus keeping up with the Jones's.

'Cause Haldex sucks. Torsen is the better, but yet more expensive, system. Haldex is just a clutch, reacting on the impulses of an electric system. Torsen delivers better traction and a faster reaction. Haldex is often used in cars to provide a cheap AWD system, like in the Golf/Rabbit or Audi R8 (which would run better with pure RWD) While the Impreza and Evo, well known for their superior AWD-Systems, run both on Torsen Differentials.

While the TORSEN is a proven product (it should be after all these years), it cannot be disabled or adjusted. This is a permanent system. The variable tq split, while dynamic, is limited to only one input (differential speed). A modern Haldex can link to the CAN-bus (or FlexRay controller now) and take inputs from ESP and suspension controllers to maximize efficiency and send the power where its needed, when its needed...in real time. I must admit, there have been questionable applications of the Haldex diff in the past (Volvo), but the new generation controllers are excellent. Watch a Veyron do 0-60. Very little wheel slip. Perfect balance between electronic throttle, tq shifting, and brake interventions. Thats all accomplished through hi-speed communication between all the systems.
