Fast Autobahn acceleration comparison between two equal equipped 2013 Audi A6s (4G). The only difference between those two cars is the engine. While the 2.0 TDI is a 4-cylinder Diesel with 177hp and 380Nm the 3.0 TDI is a 6-cylinder with 204hp and 400Nm. Many people that are currently interested in ordering a Diesel A4, A5 or A6 with a medium powered Diesel might be interested in this comparison because it answers the question if the hp -difference really is noticeable. Both cars have the multironic transmission and front-wheel-drive. Both are sedans and run on 255/40 R20 wheels, so the result should be pretty reliable. The weight difference is just 60 kg and the real life consumption is almost the same level with a slight advantage for the smaller engine.
