Have had my Lusso now for about 4 months - 4,000kms. I understand that the front wheels only ever carry a maximum of 20% of the torque. However, even after switching tires to wider, stickier snow tires, I find that the traction on this car is no better than, (in fact probably worse than) my 812 (notwithstanding that the Lusso has 100 less hp, and is heavier). I find that the rear tires spin pretty readily on take-off, and in 2nd gear acceleration. It seems to hunt for traction more on uneven roads that I would expect from a 4 wheel drive car. I have never felt or heard anything from the front tires that suggest they are carrying any of the torque - with one exception. When going around a medium radius ramp, I notice an undesirable "nibbling" action from the steering as though the front differential is locking/unlocking while modulating power between the front wheels (not in a good way, more of an irritation). Have any of you noticed similar behavior, or should I assume that I have some sort of malfunction in the front wheel drive system? (PS: It has been checked by the dealer on two occasions and they claim everything is working as it should be). I always drive in Sport mode. Thanks.
