The RS5 is way too little, way too late. The car is not even available for sale in the USA and is being touted as a 2013 model. By the time it is for sale in 2012, will anyone really care any longer? Even with a higher redline, direct injection, larger displacement, and higher compression paired to a dual clutch transmission the RS5 puts up numbers that would have a hard enough time pulling away from the E46 M3 let alone the E92. The car manages a firstname.lastname@example.org, not even an improvement on the RS4. Audi uses a drivetrain that simply is not conducive to high revving powerplants. AWD sucks too much power and adds too much weight for the RS5 to be competitive with the M3. The car should have had forced induction, period. When this car hits, BMW will be readying the next generation M3. Is the RS5 even relevant?
The M3 continues to be the car to beat in the segment and shows that sometimes less is more.
