SKN Adds up to 140 Horsepower to the Mighty Audi S6

Station wagons like the Audi S6 Avant aren’t exactly what we’d call sexy cars. But even if there’s a lack of curves on the S6 Avant’s design, it doesn’t mean that people won’t gravitate towards it, especially when you have an engine tuner like SKN providing you with options to upgrade the car’s powertrain.

The German tuning firm is offering three set of power upgrades for the 2012 and later S6 Avant, each coming with a significant power increase designed to give the Audi station wagon some serious power.

The stage-one program "only" comes with an optimized ECU unit, taking the 6 Avant’s 4.0-liter TFSI twin-turbocharged V-8 engine and increasing its output from 420 horsepower and 406 pound-feet of torque to 542 horsepower and 507 pound-feet of torque. With this upgrade, the S6 Avant is now capable of hitting 0 to 100 km/h (62 mph) in 4.6 seconds with a top speed of 192 mph. The stage-one kit will set you back £2,601.30 (roughly $4,116 at the current exchange rates).

Moving on up to the stage-two program, SKN keeps the ECU upgraded and adds a new sports exhaust system, giving more output to the tune of 551 horsepower and 513 pound-feet of torque. That’s good enough to increase the Audi’s top speed to 193 mph. This kit will run you £3,000.63 ($4,748).

Finally, there’s the stage-three program, which increases the output to 560 horsepower and 517 pound-feet of torque. This program allows the S6 Avant to shave one-tenth of a second off of its 0 to 100 km/h (62 mph), dropping it from 4.6 seconds to 4.5 seconds with a top speed of 193 mph. This kit uses all of the parts found in stages one and two, and adds in a Milltek Performance exhaust system with MOTORSPORT downpipe and intake optimization to reach those astronomical numbers. The stage-three kit will drain your bank account of £3,471.30 ($5,493).

Other than the engine, SKN is revising the S6 Avant’s looks with the installation of a new front fascia, a sporty rear diffuser, a suspension-lowering module, and a set of 20- to 21-inch wheels.

You can purchase these kits at SKN’s website.
