Audi A6 Avant

Audi A6 Avant 2.0 TDI 177 PS

The new Audi A6 Avant 2.0 TDI 177 PS will manage 56.5 mpg and 132 g/km CO2 – thanks in part to a 70 kg weight saving.

The engine line-up in the UK also includes the 3.0-litre V6 TDI in 204 PS and 245 PS outputs.

Later in 2011 an all-new 3.0-litre twin-turbo TDI will be the most potent V6 and the fourth diesel-powered option in the range. Thanks to a two-stage turbocharger that delivers a maximum boost pressure of up to 3.2 bar, the TDI flagship will take just 5.4 seconds to reach 62 mph from rest, and will be electronically limited to a 155 mph top speed.

All of the engines use the technologies from the Audi modular efficiency platform, including the start-stop system, energy recuperation and the innovative thermal management system that quickly brings the coolant and motor oil up to operating temperature. These ancillary features make a major contribution to a reduction in fuel consumption of up to 18 per cent compared with the outgoing model.

Transmission options, based on the engine choice, will include a manual six-speed transmission or 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 gives a further boost to overall efficiency.

The latest generation quattro all-wheel-drive with a crown gear centre differential and a torque-vectoring function for optimum traction, stability and response will be standard for the 3.0 TDI 245PS and 3.0-litre TFSI petrol models. For the top-of-the-line engines, the quattro sport differential – which is capable of apportioning torque between the rear wheels – will also be offered as an option.

Thanks to the use of aluminium components – which make up roughly 20 per cent of the body – gross weight has been reduced by as much as 70 kg, depending on engine, compared with the previous model. The A6 Avant 2.0 TDI , for example, has a kerb weight of just 1,640 kg.

New energy-efficient electromechanical power steering, in conjunction with the lightweight suspension set-up with its considerable aluminium content, will improve handling. The reduced unsprung mass will also increase ride comfort and this can be enhanced even further if the optional adaptive air suspension is chosen.

The Audi drive select adaptive dynamics system will also be standard in the new A6 Avant, allowing drivers to fine-tune the car’s responses as desired via the Multi Media Interface (MMI) screen. In front-wheel-drive models the latest Electronic Stability Programme (ESP) with electronic limited slip differential promises to maintain optimum control without impairing responsiveness.

Two specification levels – SE and S line – will be offered in the UK, each including alloy wheels, leather upholstery, cruise and front and rear parking controls, SD-based satellite navigation, Bluetooth phone preparation, split/folding rear seats and light and rain sensors. S line models will add larger 18-inch alloy wheels, Xenon headlamps with LED daytime running lamps, sports suspension, upgraded Valcona leather upholstery and an exclusive S line exterior and interior styling treatment.

First UK orders open in June with first deliveries in November, with prices from £32,100.
