Audi BiTDI V6


Audi has come up with a new diesel engine to slot above the single-turbo 204PS and 245PS versions of the 3.0 TDI already in use.

It’s called the BiTDI V6 and it features a two-stage turbocharger group that delivers a maximum boost pressure of up to 3.2 bar, helping the A6 3.0 BiTDI quattro Saloon to lunge at the horizon and pass the 62mph marker in as little as 5.1 seconds, and the A6 Avant and A7 Sportback to do the same in just 5.3 seconds.

That is because it makes 313 PS and 650 Nm of torque. But it i fitted with Audi modular efficiency platform, including start-stop and recuperation systems and the innovative thermal management, so all the while it manages to do 44.1 mpg. That’s brilliant for that kind of performance.

The new twin-turbo V6 is notable not only for being the most powerful six-cylinder diesel engine ever offered by the Vorsprung durch Technik brand, but also the sweetest-sounding. Available now in A6 models priced from £43,810 OTR, and from £51,645 OTR in the A7 Sportback, it combines trademark Audi TDI refinement with an exhaust-mounted sound actuator that enables it to deliver its mighty 650Nm output to the tune of a distinctly sporting soundtrack.

More details in Audi press release:

Thanks to an innovative actuator in the auxiliary channel of the exhaust system, the BiTDI A6 and A7 Sportback models don’t sound like they should be capable of such level-headed economy figures. The actuator system essentially consists of a speaker which imposes a defined oscillation pattern on the exhaust flow and transforms the typical TDI exhaust note into a more sonorous roar that is closer to the output of a high-performance petrol engine.

Without exception, power is transmitted from the BiTDI engine via an eight-speed tiptronic transmission to the latest generation quattro all-wheel-drive system, which features a self-locking centre differential and torque vectoring for optimum traction and stability.  A sport differential which distributes power in continuously variable proportions between the rear wheels is available from the options list to sharpen and quicken response even further.

The mighty new BiTDI engine is available in conjunction with SE and S line specification in the A6 Saloon, A6 Avant and A7 Sportback. The forthcoming A6 allroad quattro, due to open for order in February, will also offer this exceptional unit.

Stand-out features common to all these models include satellite navigation linked to a 6.5-inch retractable colour monitor, Milano leather upholstery, the Audi drive select adaptive dynamics system controlling throttle response, transmission shift points and steering feel, the Audi parking system plus, light and rain sensors, cruise control and keyless go push-button engine ignition.
