Last month Audi launched the A6 equipped with Audi ultra efficiency technology. The new technology seen on the A6 first ensures performance while cutting down emissions and fuel consumption by an appreciable amount. Yesterday, expanding the ultra models lineup in the UK, Audi has launched the A4 Saloon, A4 Avant and A5 Coupe. The Ultra model range is powered by a 2.0 liter TDI engine, which was earlier available on the A5 only but Audi engineers have reworked the same so that it burns fuel in a leaner manner.

The engine is capable on putting out 163 PS of power available between 1200 rpm and 3000 rpm and a peak torque of nearly 400 Nm available from 1750 rpm up to 2750 rpm. On the A5, the engine is mated to a 6 speed manual gearbox which helps the car accelerate from 0 to 62 mph in 8.3 seconds and
