2010 Audi S5

Alongside the new A5 coupe, Audi launched the 2010 Audi S5 model onward. It features Audi's direct-injection 4.2-liter V8 engine, basically a detuned version of the one found in the RS4 and R8, which produces 354hp and 325lb-ft of torque instead of the 420 hp /317 lb-ft. Like the A5, the new S5 features an engine placement behind the front wheels, resulting in better weight distribution between the axles. The A/S5 is underpinned by Audi's newest platform, B8, making its debut here. It is also the floorplan for the 2009 Audi A4, and its flexibility will allow it to underpin future A6 and even flagship A8 models. Detuned or not, the motor is good enough to propel the S5 to 60mph in under five seconds, and carry it onto an electronically limited top speed of 155mph.
