Volkswagen Group's luxury car arm Audi has released first details of its redesigned A4 sedan and Avant wagon range that will début at Paris later this month.

The 10 available engines include four units new to the A4 - 200PS 2.0 T FSI  and 255 PS 3.2 V6 FSI, and the 140PS 2.0 TDI and 204PS 3.0 TDI turbodiesels.

The new body styling features Audi's new single frame grille and styling details from the Nuvolari quattro design study shown at previous motor shows. There are new manual transmissions, plus optional six-speed tiptronic and seven-speed multitronic CVT automatics.

The interior has been updated to include new steering wheels, new cloth and leather upholstery options and new technology including DVD-based satellite navigation.

In the UK where the A4 is a popular company car choice, the 2.0 T FSI is expected to be the most popular petrol model. The best-selling TDI model, and the version accounting for the most sales overall, is expected to be the 2.0 TDI.

The chassis has been extensively revised to include components from the new A6 and upgrades previously reserved for the flagship S4 quattro.

Servotronic speed dependent power steering, originally a feature only of the S4 quattro models, is now fitted as standard to 2.0 T FSI, 3.2 FSI and 3.0 TDI models, while the braking system has been revised and now includes a brake disc wiping function, first seen in the new A6, which applies low pad pressure against the discs at regular intervals to keep them drier and therefore maximise performance in wet conditions.

Optional xenon headlights with swivelling, adaptive cornering lights, are also available.
