The Audi S7 Sportback is a car that holds up when compared to a car like the Mercedes CLS-Class . But once AMG gets into the picture and releases the CLS AMG , there’s no way that the S7 Sportback can compete with it.
That’s where ABT Sportsline comes into the picture.
The German tuner has just released a new performance program for the luxury Audi sedan, an upgrade that will give it enough added power to give Mercedes’ CLS AMG line a serious run for its money. The upgrade, which has been christened the "AS7" takes the S7 Sportsback’s 4.0-liter twin-turbocharged TFSI V8 engine and increases its output from the standard 420 horsepower and 406 lb/ft of torque figures all the way up to 520 horsepower and 442 lb/ft of torque. This allows it a new top speed of 183 mph, up from the standard 155 mph top speed of the stock model. Do the math and that equates to a 100-horsepower and 36 lb/ft of torque increase from the standard S7 Sportback and an improvement of 28 mph.
In addition to the engine modifications, ABT Sportsline also fitted the S7 Sportback with a new set of either 20" or 21"CR or CD alloy wheels to go with new suspension springs, an optional lowering module, and the ABT Level Control air suspension setting.
