Audi has added a new 2.7 TDI engine to its A6 range, designed to appeal to company car drivers due to its economy and low emissions.

Available to order now priced from £26,330 OTR, the new A6 2.7 TDI uses a light-weight six-cylinder common rail 2.7 TDI unit, essentially a downsized version of the 3.0 TDI.

The new power unit delivers its maximum 180PS output between 3,300 and 4,250rpm and 380Nm between 1,400 and 3,300rpm, giving the A6 2.7 TDI SE with six-speed manual gearbox the potential to accelerate from rest to 62mph in 8.1 seconds and to reach a top speed of 141mph. Up to 41.5mpg is possible on the combined cycle with CO2 output of 181g/km (depending on specification).

Featuring a separate high-pressure pump and rail for each row of cylinders, the system permits up to five separate amounts of fuel to be injected on each working stroke, at an injection pressure of 1600 bar, 250 bar more than with previous common rail systems. This helps to achieve the best possible fuel/air mixture and an even more efficient combustion process.

This technology ensures full compliance with EU4 emissions regulations without the use of a particulate filter. According to the latest information from Emmox Carcost, this new version also offers the lowest running costs in its specific sector, and will also achieve the best value retention over 3 years or 60,000 miles.

In common with all A6 Saloon models, the A6 2.7 TDI will from next month offer the extra cost option of adaptive air suspension. Based on the system fitted to the A8 luxury saloon since launch, the air suspension set-up features continuously variable damping to suit prevailing road conditions, and also offers the option of four pre-determined suspension settings which can be selected by the driver via the Multi Media Interface System (MMI).

The A6 2.7 TDI will be available in both SE and S line trim. SE specification includes 16-inch alloy wheels, remote control central locking, electronic climate control, electric front and rear windows and mirrors, cruise control, a 160-watt sound system with glove box-mounted CD player and the MMI Basic Plus control system with 6.5-inch monitor.

S line models add 18-inch alloy wheels, unique S line sports suspension, sports seats with black leather/Speed cloth combination upholstery, a sports steering wheel and special S line grille and interior badging. An additional S line exterior styling package is also available for S line models at an extra cost of £1,100 (£875 for 4.2 quattro versions), bringing an exclusive S line front bumper and grille design, headlamp washers and a unique rear bumper treatment with painted diffuser.
