2012 Audi S5 Premium Plus quattro 2dr Coupe AWD (4.2L 8cyl 6A)
Audi has improved on the older S5 model by adding the Rear Sports Differential where you can make the engine more aggressive, the steering tighter, and the rear wheels shift torque sidesways when cornering. Because of the dynamic mode, this S5 feels much faster, tighter, and much more fun to drive as it incorporates the technology of the new S4.
It feels as fast and fun as the new S4 compared to the 2009 S5 I tested.
In terms of gas mileage, I achieved 22 MPG on my initial break-in out-of-town trip (mostly highway), and 19 MPG in city driving. I feel that highway driving could easily get to 25-26MPG after break-in.
Beauty, performance, & the V8 sound makes the s5 as class of its own.
Grand touring ride (very comfortable on the highway) and nowhere as hard as the ride of BMW. The Sports Differential and Quattro makes the S5 run like it was on rails
