2011 Audi A4 TDI

2011 Audi A4 TDI

Right before the Frankfurt Motor Show, Audi is announcing two new A4 models, each using a different fuel.

The most exciting of the two is the A4 3.0 TDI quattro. I’m not sure if we’ll be getting this is the States (cross your fingers,) but it uses the same 3.0-liter diesel engine found in the Q7 TDI. Achieving about 35 mpg, the A4 TDI boasts 240 horsepower and even more impressive, 369 lb/ft of torque. The engine is paired with a 6-speed tiptronic transmission which can get the A4 from 0-62 mph in 6.2 seconds.

The second A4 announced runs on biofuel, aka E85. This fuel is a mixture of 85% ethanol to 15% gasoline, which provides more power, but a significant reduction in fuel economy. Great for corn farmers, not so great for consumers. Audi’s E85 engine for the A4 will be a 2.0-liter TFSI producing 180 hp and 236 lb/ft of torque. Fuel economy is terrible, as expected, at about 26 mpg. Put regular premium gasoline in the same engine and you’ll get 36 mpg – 10 mpg more. I still don’t understand why manufacturers are making these flex-fuel cars, I think they’re terrible.

To get this straight then, we have two new engines – one TDI and one E85. The TDI gets 240 hp and 369 torque and achieves 35 mpg, while the 180/236 E85 gets 26 mpg.


Yes, E85 fuel is a bit cheaper since the government wants you to use it, but not that much cheaper. I’ll stick with the TDI, thanks.
