Audi A6 BiTDI Competition Is Impressively Stable While Doing 165 MPH

The era of hot diesels didn’t start with the current S6 as Audi has been selling cars with torquey V6 TDI engines for many years. This video shot by YouTube’s No Limit Autobahn reminds us of a potent A6 diesel from the previous generation, seen here in the Avant specification. It’s a special-edition Competition model with a 3.0-liter six-cylinder engine equipped with a pair of turbochargers.

The engine produces a healthy 326 horsepower and a brawny 650 Newton-meters (480 pound-feet) of torque in normal mode, but there’s an overboost function lifting output to 346 hp. Numbers aside, this A6 wagon is a real diesel monster as it blasts down the Autobahn where some of the areas don’t have any speed limits.

It’s not every day we get to see a diesel wagon doing 165 mph (266 km/h) without actually breaking any laws. The car remains perfectly stable and comfortable even at high speeds, while the noise generated by the V6 BiTDI engine is not obtrusive at all. It’s that type of vehicle born to devour the Autobahn by covering hundreds of miles without breaking a sweat.

Aside from taking the A6 Competition (C7) to the maximum, the man behind the wheel was also curious to find out how the car would fare in a test from 100 to 200 km/h (62 to 124 mph). It completed the task in a not-too-shabby 15.6 seconds and dare we say it provided a nice soundtrack while under hard acceleration.

The video is also a good indication of how impressive the first-ever S6 diesel is considering it has substantially more power. The electrified TDI packs an extra 23 hp and 50 Nm (37 lb-ft) over the old A6 BiTDI Competition, but bear in mind the TDI version of the S6 is sold exclusively in Europe. The rest of the world gets a more traditional V6 gasoline mill carried over from the RS4 Avant with 444 hp and 600 Nm (443 lb-ft).
