Audi plans to introduce diesel variants to four cars in the U.S. that were previously gasoline restricted.
Those will be the A8, A7, A6 and Q5 crossover, all getting the same 3.0-liter diesel powerplant — a move Audi says will boost fuel efficiency by 30 percent.
The 3.0-liter powerplant will pack 240 hp and a whopping 406 lb-ft of torque while returning an estimated 24 mpg in the city and 36 on the highway. Of course, that engine is nowhere near as powerful as the ridiculous W12 engine buyers could find in the W12 A8L, which offers 500 hp.
Then again, the torque ratings aren’t all that different. The executive-aimed limousine version commands a heavy premium and boasts 463 lb-ft of torque, but your chauffeur will be hard pressed to meet even half the estimated fuel economy of the diesel engine.
Performance driving really isn’t what the A8 is all about, which means that torque rating is all the more relevant.
The same can be said for the A7 and A6, albeit in a less luxurious package. Meanwhile, the Q5 will join its larger Q7 sibling in being able to burn diesel fuel. Audi will also offer the same 3.0-liter diesel in the Q7, likely hoping to take advantage of sharing production costs between a wide range of vehicles.
