First and foremost, drivers familiar with previous Audi builds will notice the impressively power-packed 5.2 V 10 under the hood. The specific engine design of the 2011 Audi S6 may be recognized by high-performance fans: it also powers the Lamborghini Gallardo. While the impacts on fuel efficiency and overall weight are not to be minimized, the raw power this engine delivers can't be beat in the S6's class. Coupled with the Lambo V10's raw potential are the powerful and responsive brakes this sedan boasts, a must-have when considering the car's weight and front-shifted balance. This reviewer was not able to personally verify Audi's acceleration claims, but the company is currently pegging the S6 at 5.1 seconds from 0-60 mph.
While the 2011 Audi S6 is a powerhouse on the straightaway, its handling suffers a bit due to the massive weight distribution difference between the car's front and rear points of contact. While Audi's responsive and highly advanced transmission technology skews the relative generated torque to compensate for the massive engine's unbalancing effect on the chassis, the result is not pitch-perfect; drivers used to the tight controls and quick maneuvers of lighter sport sedans and coupes may find the 2011 Audi S6 to be more of a sprinter but less agile than they'd hoped. Despite this gripe, the S6 is most certainly a pleasure to drive. The unmistakable rumble issuing from the powerhouse of Audi's choice engine will turn heads and attract the jealousy of those driving many of today's nimble yet chronically underpowered coupes. Despite the horsepower Audi's V10 is capable of delivering, drivers should remove the idea of ultra-high-speed driving from their S6 fantasies: Audi's engineers installed software limiters that prevent the car from exceeding 155 mph as a safety measure.
