The new Audi A4 is the definitive vehicle of the mid-sized sedan market and with Abt Sportsline engineers having refined the new model further, the result is an expressively-designed and exceptionally-engineered vehicle signalling a true victor of the class.

The Abt AS4 is styled to personify strength and agility without losing the A4's sense of elegance and is much a smooth cruiser as the Audi production model it is based on - all while throwing a sportier experience and more agile ride into the mix.

And these strengths are primarily accentuated through a new bodykit. Marked new front skirts, highlighting the car's headlamps, flow into new side wings and through to the 'acutely dynamic' rear end, finished off by a new rear spoiler and the addition of quad exhausts neatly-integrated into a new rear skirt.

Starting with a host of bar-raising drivetrains available from the new A4 range, Abt Sportsline engineers had a superb base on which to build. Kicking off with the A4's new turbocharged 1.8-litre TFSI unit, Abt Power boosted output from 160 to 200 PS with 310 Nm of torque now available on tap. With the optional Abt Power S upgrade, output from the 1.8 TFSI increases to 240 PS. It is a similar scene across the line-up. An Abt Power kit increases output from 143 PS on the production model 2.0 TDI to 170 PS and 200 PS with Abt Power S. From the 2.7 TDI comes power of 190 PS and 230 PS from the two respective power kits, while the 3.0 TDI generates 300 PS from the Abt Power S upgrade.

A 'perfectly tuned' suspension setup provides the car with an agile response and excellent road-holding ability at every corner, while specially-developed Abt and Abt Sports brakes enable powerful braking responses. A range of 18", 19" and 20" Abt sports alloys complement the AS4 'exceptionally'.
