The TDI engines of the Audi A6 allroad quattro.

Intelligent performance.

Higher power with lower fuel consumption: a paradox we’ve reconciled in our revolutionary Audi TDI engine and drive technology.

Combining direct injection and turbocharging, the 3.0 TDI engine delivers exceptional performance and high torque output over the entire engine speed range, and constant power build-up. Renowned for being fuel-efficient and for reducing emissions, the TDI engine is incredibly versatile too, letting you get the most out of any road.

Innovating efficiency.

Fuel consumption and emissions are continually reduced by innovations like the start-stop system, which automatically switches off the engine during stationary phases. Audi drive select comes as standard, with five modes that ensure individual vehicle adjustment—from comfortable to sporty, and energy efficient.
