Audi Reveals New 3.0L Diesel V6

Audi has new diesel V6 engines waiting in the wings with improved efficiency ready for stricter European emissions standards.

The company revealed a pair of heavily updated 3.0-liter diesel V6 engines today in Vienna with improved efficiency and enhanced power compared to the mills they replace. There are two versions: one with 218 hp and the other with 272 and up to 442 lb-ft of torque. Audi says the 90-degree engines, depending on model, will offer up to a 13 percent fuel economy improvement.

That improvement is thanks to a long list of revised internal components for friction reduction including new piston rings and pins. There’s a new crankcase and redesigned cylinder heads with separate coolant loops and an updated thermal management system. The turbocharger has also been revised for the new engines.

Last year, Audi expanded the range of vehicles it offers in North America with with its previous 3.0-liter diesel V6 to include the Q5 crossover, A6, A7 and A8 sedans. In those applications, drivers get 240 hp and 428 lb-ft of torque. The Q5 equipped with a 3.0-liter diesel is officially rated to return an average 27 MPG. If fuel efficiency is really improved by 13 percent, that would mean the new car could return over 30 mpg on average.
