The 2012 Audi A6 Avant has received a new tuning kit courtesy of Audi tuner extraordinaire, ABT Sportsline. Aesthetic upgrades are part of the package, but the main ingredient of the whole thing is an extensive performance upgrade that takes the output of the estate car to a whole new level.

Among the changes you’ll notice on the exterior include a new front spoiler, new sidebars, a custom rear spoiler, a new rear apron that integrates four exhaust pipes, and a set of 19", 20", and 21" lightweight wheels that comes wrapped with high-speed tires.

As for the engine, the 2012 A6 Avant is powered by a number of engine options, including a 3.0-liter TDI engine with a choice output of 204 horsepower and 245 horsepower and a 2.0-liter TFSI engine that produces 300 horsepower. On it’s own, these engines are impressive, right? Not to ABT Sportsline.

Using a few engine modifications, the German tuner was able to bump up the output of the two 3.0-liter TDI variants from 204 horsepower to 240 horsepower and 245 horsepower to 300 horsepower. As for the gas-powered 2.0 TFSI engine, the original output of 300 horsepower has been juiced up to a mouth-watering 420 horsepower, improving the car’s 0-62 mph time to just under five seconds.[...]
