Car and Driver said the M5 had dull steering and was unsatisfying. Historically, if one had to pick which car out of these three these comments would be applied to fingers would point to the Audi. Times sure have changed and it is rather sad to see a car like the M5 fall this far. Traditional BMW strengths are the fun factor and steering feel. It is supposed to be the most involving. What has happened?
The E63 finishes in second place. Praise for its steering, engine sound, and torque are all given. Yes, the Benz has better feedback and communication than the M5. Its motor also does not need to fake its engine sound. The E63 was referred to as robotic but also entertaining which is somewhat of a conflict.
This brings us to the winner, the Audi S6. On paper it is easily beaten by the E63 and M5. This is the least powerful car in the group by a fairly wide margin with 420 horses compared to the M5's 560 and the E63's 518. Car and Driver said the power difference simply didn't matter and it is somewhat apparent in the 1/4 mile times. The S6 manages a 12.1@115 compared to the M5's 11.9@123 and the E63's 12.0@124. The power disparity shows in the traps but the Audi's Quattro helps it run door to door with the other two in the 1/4 mile. The RS6 is going to mop the floor up with them as we expect it to run mid 11's stock.
The S6 is also slightly lighter than the M5 despite having Quattro. This would have been unheard of just a generation ago.
The Audi is said to be the most complete car inside and out. It feels more special inside. It has more personality. This is a major sign that times are changing as Audi and Mercedes are getting better and BMW has fallen off. A shame really, but congratulations to Audi. We eagerly anticipate the RS6.
