2011 Audi S5 3.0T Premium Plus quattro 2dr Convertible AWD (3.0L 6cyl S/C 7AM)
Had considered an M3. After I drove the S5 Cab there was no turning back. The interior blows you away compared to the BMW. My dealer suggested an ECU upgrade pushing the car to 410 HP with 370 lb-ft of tqe. The car is as you can imagine super fast. Zero to 60 4.3 seconds. Right there with the M. Big difference is the quatro. Makes the car stick to the road like glue.
style, speed, control
add voice rgecognition in the cabriolet like the coupe.
What ECU upgrade?
Did you get it?
How much did it cost?
Does it void the warranty?
Does the dealer sell these ECU upgrades?
I really like the overall appearance of the S5, but I really like the power and handling of the M3.
If the S5 ECU upgrade matches the power like you indicate, I would more than likely lean towards the S5 and save myself about 20k in the process.
