2019 Audi A6 review - does the new A6 finally drive better than its rivals? - Engine, transmission and technical details
The Audi A6’s core virtues remain, but it doesn’t shine like it once did - rivals still do executive better
Engine transmission and technical details
The 40 TDI’s 2-litre EA288 diesel power unit now uses an alloy rather than a steel block, for claimed refinement benefits and 20kg less over the front wheels. It’s a little more potent than the old diesel too with 201bhp.

The 45 TFSI model features a 242bhp version of the EA888 2-litre turbocharged four-cylinder petrol engine mated to the seven-speed S-tronic. Despite similar numbers to those found in a Golf GTI, the two are worlds apart on the road, lacking much of the Golf’s enthusiasm - not surprising considering the two cars’ very different missions.
The familiar turbocharged V6 diesel is badged 50 TDI and cranks out 282bhp and 457lb ft to the road. As mentioned above, it uses an eight-speed Tiptronic torque converter automatic, and unlike the 55 TFSI, its quattro system uses a self-locking centre differential, rather than a multi-plate decoupling clutch. Top speed is 155mph with a 5.5-second 0-62mph run, plus the potential for 50.4mpg economy on 18-inch wheels.
