In Audi-speak, the '35 TDI' badge on the trunk is there to tell you this version of the A4 comes powered by a four-cylinder 2.0-litre diesel engine. Peak power is a strong 190hp and max torque is an impressive 400Nm. These figures are identical to the BMW 320ds engine and also put the A4 diesel right between the Mercedes-Benz C220d and C250d diesels on the power scale. However, where its rivals are rear-wheel drive, the A4 diesel is front-wheel drive only; there’s no Quattro version in either.

The 2018 Audi A4 delivers just about everything we expect from a small luxury sedan. There's quick acceleration, a comfortable ride, and the latest connectivity and navigation technologies. But the fact that it does it without overwhelming you makes it, at least for the time being, the car to get in the segment.
