sandrafish9: Audi AS7 Sportback by ABT Sportsline

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.
