Well not quite Deutsch, bearing in mind that 100% of engine torque is being distributed to one axle only, the basic physics involved in the process still mean that a car with 25% torque at each wheel will lose grip later than a car with 50% torque at each wheel. Fancy electronic differentials like this will maximise the available surface grip but cannot change the fact that, in all conditions, under the application of torque (putting your foot down), the slip angle on the rear tires will be greater than that at the fronts, resulting in a loss of stability. Hence, electronic stability programs are still needed.

didn't understand a word, but i notice something, in the first picture i think bmw should put the gearboxe right after the differential , it you would give it a better balanced, more rear bias wheight distribuition, maserati uses it, bmw should too

Thanx to u, EnI
didn´t see thread before

How will moving the diff forward to be right after the transmission help move the weight distribution backwards? While it is beneficial to concentrate all weights around the middle of the car (to reduce moment of inertia), in a Front engined car, placing the diff towards the rear of the car helps balance the engine weight and get a more balanced weight bias between the 2 axles.

This is one great sytem to have in a car..Kudos to engineers who developed this system and zo BMW on implementing it to their cars

He said gearbox after the differential and not differential after he gearbox, I think he meant brining the gearbox backwards

Yup my bad.
