Audi makes A3 2.0 TDI greener

Audi has launched a 'stop-start' version of the 2.0-litre TDI A3 with improved fuel economy and lowered CO2 emissions.

Power remains unchanged at 138bhp, but the car uses green technology, including an engine 'stop-start' system, to deliver dramatically improved efficiency.

Audi has also introduced a part-time alternator, which recharges the battery under braking, recuperating energy that would otherwise be lost.

CO2 emissions slashed by 16%
The package of changes mean that the A3 2.0-litre TDI hatchback now manages an average of 64.2mpg up from 55.4mpg on the non-stop-start version while CO2 emissions have fallen by 16% from 134g/km to 115g/km. Company car tax liability is cut from 18% to 13%.

The new efficiency measures mean that the A3 2.0-litre TDI is almost as green as the less powerful 1.6 TDI (67.3mpg and 109g/km) and better than the similarly powerful BMW 118d, which manages 62.8mpg and 119g/km with a manual gearbox.

The A3 Cabriolet 2.0 TDI gets the same green technology, which helps to boost fuel economy from 53.3mpg to 61.4mpg and cuts CO2 emissions from 139g/km to 119g/km.

Prices remain unchanged, with the entry-level A3 2.0 TDI three-door costing 18,860.
