Audi tuning specialist Motoren Technik Mayer has introduced its latest project: a power pack for the feisty S6. By combining its M-Cantronic with the V-Cantronic in one unit - jargon for remapping the ECU - MTM were able to boost output from 420 hpand 406 lb-ft of torque to 555 hp and 516 lb-ft of torque. However that boost in power is available on tap. MTM has worked it so that the S6's twin-turbocharged 4.0-liter V8 can reach RS6 levels of performance with a press of a button, via the car's multimedia interface (MMI) system.

With the added power, a top speed of 181 mph can be reached. The conversion, which can be made permanent, is priced at 3,700 Euros, while a stainless-steel quad exhaust is available for an additional 4,300 Euros. MTM also offers a choice of its Bimoto alloy wheel sets, priced between 2,100 and 5,300 Euros, and an F-Cantronic lowering module that drops the S6 by 25mm up front and 20mm at the back, which can be yours for 2,000 Euros.
