Unlike regular Audi quattro models, however, the RS 5 is fitted with sport diff, which actively distributes power between the rear wheels. (digitaltrends.com)
The chassis is clearly very well sorted, the balance with the sport diff is adjustable and not relentlessly understeery, but the weight savings advertised don't really make themselves felt. (evo.co.uk)
Of course it can be made to understeer if you don't listen to the howling tyres (it comes as standard with Hankooks, which are brilliant in the wet but lack response and mid corner grip in the dry), but if you turn the car in slightly slower and then commit to the throttle you feel the sport diff sending power to the outside rear tyre.
