The start point for the best source of fleet information

Audi starts with stop-start

Date: 05 March 2009

Audi A5 Convertible

Audi is catching up with arch-rival BMW's Efficient Dynamics low-CO2 programme with the launch of start-stop technology.

Claimed to be worth around 5g/km to the emissions figures, the system apes that of rivals including BMW and Toyota in cutting the engine when the car's stopped in neutral with the clutch disengaged.

Coming first to the A5 range, it will arrive at the same time as the new A5 Cabriolet (pictured) and be available on manual versions of the 2.0-litre petrol and 2.0-litre diesel models.

The A5 coupe will also follow shortly afterwards, in the second half of 2009, with the A4 range next in line as it uses the same engines.

A4 and A5 product manager Henry Williams told BusinessCar that all outputs of the 2.0-litre diesel engines will get the technology, which in the A4 means 120, 140 and 170PS alternatives.

The technology will also eventually filter over to the A3, A6 and Q5 models, although no timescale has been revealed.
