Audi Q5

Audi A8
Audi A6, A8, and Q5 to get TDI power

Audi is no stranger to diesel engines. In Europe and other world markets, Audi has a number of TDI options available for consumers for the many models in its lineup. In the United States, however, those looking for a diesel Audi can only choose from the tiny A3 TDI or the mammoth Q7 TDI.

Now, according to Fourtitude, Audi is looking to spread a bit more TDI lovin' to customers in the U.S. The company just announced today that it would bring its 3.0-liter TDI engine to the A6 sedan, A8 sedan, and Q5 small crossover vehicle.

Those still holding out for a TDI engine in the popular A4 sedan and Avant will have to wait a little longer. Audi officials say that since the current A4 is already in the "advanced stages" of its lifecycle, that U.S. customers will have to wait until the next generation A4 arrives in a few years. 

The 3.0-liter TDI coming to the A6, A8, and Q5 is already available in the Q7 TDI. It generates a respectable 225hp at 3,750 rpm and a gargantuan 406 lb-ft of torque at 1,750 rpm in that application. The engine is capable of giving the 5,567-pound crossover EPA ratings of 17 mpg in the city and 25 mpg on the highway. 

The three new TDI models are much lighter which should make the fuel economy gains even more impressive compared to their gasoline engine counterparts.

There were recent reports that General Motors is looking to bring a diesel engine to the U.S. market for its Cruze compact instead of going for a fully-fledged hybrid model.

There's a few smaller diesels available in the EU from various manufacturers for their small hatches but they don't tend to work particularly well as performance is poor and fuel economy isn't that much better over similar petrols.

It used to be that most diesel engines were a higher capacity and then the power output adjusted to suit the purpose, VW/Audi for a long time use a 1.9 diesel engine which varied from just 65bhp in its non-turbocharged form up to 150bhp for the sportier versions with various values in between. Now however they're replacing the lower powered 1.9's with a 1.6 TDI common rail engine with mixed results, it's meant to be a lot smoother than the outgoing 1.9 but fuel economy in practice isn't that great.
