When it’s not working on high-powered RS models such as the RS6-R, ABT Sportsline enjoys tweaking some of the more unassertive models from Audi’s vast range. For their latest project, they picked what is arguably the most versatile car in Ingolstadt’s lineup – the A6 Allroad. The do-it-all lifted wagon gets new shoes in 20- and 21-inch sizes, but the real magic is under the hood.
ABT upgraded the top-tier diesel engine, available in the confusingly named 55 TDI model. It’s a 3.0-liter V6 turbodiesel that normally produces 349 horsepower (257 kilowatts) and 700 Newton-meters (516 pound-feet) of torque. The Kempten-based tuner managed to lift those numbers to a healthy 384 hp (282 kW) and a mountain-moving 760 Nm (561 lb-ft).
While there’s no word about how the power boost has positively impacted the car’s performance, we’ll remind you the A6 Allroad equipped with the range-topping diesel engine does 0 to 62 mph (100 km/h). There’s an electronic top speed limiter programmed to kick in at 155 mph (250 km/h).
Even though not many customers go for the gasoline engine, ABT also massaged the 3.0 TFSI V6 available in the 55 TFSI model. It’s up from the series 340 hp (250 kW) and 500 Nm (369 lb-ft) to 408 hp (300 kW) and 550 Nm (405 lb-ft). The significant power boost has likely shaved off some time from the 5.5 seconds needed by the standard gasoline-fueled A6 Allroad to do the sprint. Much like the diesel, top speed is electronically governed at 155 mph (250 km/h).
If you happen to have an A6 Allroad but with a lesser diesel engine, you should know ABT has also worked on the midrange 50 TDI, taking it from 286 hp (210 kW) and 620 Nm (457 lb-ft) to a respectable 330 hp (243 kW) and 670 Nm (494 lb-ft).
With Audi having an answer to just about every niche there is, some of us would like to see a mashup between the A6 Allroad and the RS6 Avant. A V8-powered RS6 Allroad with 600 hp would be great, although Audi is probably concerned very few would actually buy one. The next best thing are tuner packages for the Allroad, unless you go the other way by jacking up the suspension of an RS6 and throwing in some plastic body cladding and extra underbody protection.
