In Audi’s quest to reduce carbon dioxide emissions and improve fuel economy among its fleet, a stop-start system is to be added to selected vehicles towards the end of the year.
The manufacturer is hoping to progress the average fuel economy by a further 20 per cent by 2012, with moves beginning to implement the changes in the third quarter of this year.
Carbon dioxide emissions are expected to fall by 5g/km on vehicles featuring the technology, with the Audi A3 1.4 TFSI with manual transmission tipped to be the first.
Meanwhile, the system is also set to be included in 2.0-litre versions of the Audi A4 and Audi A5, alongside other models later in the year.
The aim of the start-stop system is to improve fuel efficiency, especially in urban areas, as the system turns off a car’s engine when the vehicle comes to a stop, with the engine automatically being turned back on when a driver pushes down their clutch in preparation to pull away again.
Motorists interested in buying a vehicle from the Audi A3 range could choose the A3 Cabriolet, which according to the manufacturer is designed for "pure open-top driving pleasure".
