Salzhemmendorf-based SKN Tuning GmbH has created a range of products to bulk up Audi’s brilliant S6 model.
The company offers various performance upgrades, beginning with Stage One, which is an ECU software tweak that results in 399 kW (542 hp) and 687 Nm of torque from the twin-turbocharged 4.0 TFSI V8, up from 309 kW (420 hp) and 550 Nm. Next, Stage Two sees the inclusion of a new exhaust system with Milltek motorsport downpipe, helping to make 405 kW (551 hp) and 696 Nm.
Finally, Stage Three involves all of the above plus optimization of the intake system, which brings output up to 412 kW (560 hp) and 700 Nm, identical that of the new Audi RS 6.
Pricing for the conversions are €2,990, €3,449 and €3,990 respectively.
Other components available includes an adjustable lowering module allowing a drop of up to 40 mm, a rear spoiler, diffuser section and a range of alloy wheels in a 20 and 21-inch diameter.
