Audi A6 (C7) Diesel With 451 Horsepower Unleashed On The Autobahn

It’s safe to say diesel engines are generally frowned upon nowadays in the aftermath of the emissions scandal at the Volkswagen Group. That hasn’t stopped Audi from installing a TDI engine in the S4 through S7 models on the Old Continent in a move that took just about everyone by surprise. The Four Rings have a long tradition of developing hot diesel cars, even if these models never earned the S badge.

One relevant example is the previous-generation A6 (C7), which was offered in Europe with a torquetastic 3.0-liter V6 diesel equipped with a pair of turbochargers. In stock form, the TDI developed 313 horsepower and a whopping 650 Newton-meters (479 pound-feet) of torque. These remain some healthy numbers even compared to the S6 available today.

The folks over at AutoTopNL had the opportunity to get behind the wheel of a C7, not just any previous-gen A6, but a version tweaked by JD Engineering. With 451 hp and a mountain-moving 931 Nm (687 lb-ft) on tap, this amped-up large diesel sedan can devour the Autobahn for miles on end without breaking a sweat.

The massive power bump enables the car to hit 62 mph (100 km/h) from a standstill in 4.5 seconds, thus making it 0.6s quicker than the standard model. The Dutch tuner also got rid of the top speed limiter capping the car at 155 mph (250 km/h) to unlock a maximum velocity of roughly 168 mph (270 km/h).

It’s worth mentioning this is a high-mileage car, showing more than 235,000 kilometers (146,000 on the odometer). It pulls impressively strong and doesn’t sound half bad either for a “tractor” as some refer to cars running on Devil’s fuel.

The VW Group insists its diesel engines are now cleaner and more efficient than ever, and you can still get a TDI in plenty of models from the German conglomerate. What this tells us is the diesel is not going anywhere in the foreseeable future, even if VAG is investing heavily in hybrids and EVs. As they say, variety is the spice of life.
