Editorial view:

The 2.0 TDI diesel engine is far and away the biggest seller in the 2021 A4 range due to its exceptional combination of fuel economy, emissions and usable everyday power. Audi offers the engine in a choice of front wheel drive or 4 wheel drive in the quattro model on more powerful versions, and currently offers the 30 TDI, the 35 TDI and 40 TDI powerplants, all with the S-Tronic automatic gearbox as standard.

The 30 TDI uses a 2.0 TDI 136 horsepower Ultra model is the most fuel efficient, with CO2 figures of 104g/km and official WLTP combined fuel economy figures of 54.3 miles per gallon, making it great for the executive business user who wants to keep their personal taxation levels low.

Next is the 35 TDI engine, which uses the same basic 2.0 litre architecture, with turbo boost increased to give 163 horsepower, knocking the 0-60 time down from 9.5 to 8.2 seconds and increasing top speed from 130 to 142 mph.

finally the 40 TDI has 190 horsepower and also gets the Quattro drive train as standard to get the power and torque down onto the road more efficiently. This means the car weighs slightly more from all the 4 wheel drive gubbins underneath, so you get a small knock to the fuel economy, but acceleration times and traction in poor conditions is significantly better.
