Audi A6

The all-new Audi A6 with lighter body and fuel economy of 57.7 mpg

The all-new Audi A6 is almost here, and with a lighter body, its emissions will be as low as 129 g/km CO2, with 57.7 mpg; a hybrid is also on the way.

The new A6 opens for ordering in the UK in January 2011, with first customer deliveries in spring 2011.

Composite aluminium and steel construction means that the 2.0 TDI model weighs just 1,575 kg, 15% less than an all-steel equivalent.

There will be a choice of four engines at launch – one petrol and three diesels – teamed with manual, multitronic or S tronic transmissions – multitronic CVT or manual for front-wheel drive, and S tronic for quattro models.

The A6 2.0 TDI (177 PS) manual is the most efficient model; although capable of 0-62 mph in 8.7 seconds and a top speed 142mph, it emits just 129 g/km CO2.

The 2.0-litre TDI 177PS, 3.0-litre TDI 204PS, 3.0-litre TDI 245PS and 3.0-litre TFSI 300PS engines all come with technologies including start-stop, energy recovery system and thermal management. As a result, fuel economy has improved by up to 19 per cent compared to the previous model.

The 2.0-litre TDI, with its six-speed manual transmission, returns 57.7 mpg combined and emits 129 g/km CO2 . An A6 hybrid will also be available, combining a 2.0-litre TFSI petrol engine with an electric motor. This will be capable of zero-emission urban driving and up to 45.6 mpg, yet will also develop 245 PS.

Transmissions will include a manual six-speed transmission or continuously variable multitronic CVT for front-wheel-drive models, and the new seven-speed S tronic twin-clutch transmission for quattros. Each unit features a wide gear-ratio spread which improves efficiency.

There will also be new energy-efficient electromechanical power steering and lightweight suspension. In addition, the new A6 is also more aerodynamic, with a 0.26 Cd drag coefficient.

Two specification levels – SE and S line – will be offered in the UK. Prices will start at £30,145 for the A6 2.0 TDI SE.
