The MTM-Tuned Fostla-Wrapped Audi RS6 Avant

MTM Fostla RS6 Avant

A super car in family-car form.

The C7-generation of the A6 may be the current offering from Audi but the C6-generation RS6 Avant will always be one of those cars that live on as being one of the most powerful models in the history of the automaker. The RS6’s engine was packed with potential, leading aftermarket tuners like MTM – Motoren Technik Mayer and Fostla to develop programs that push it to its limits.

The Audi-tuning specialists at MTM have teamed up with Fostla to tune and style the Audi RS6 Avant. The 5.0-liter, twin-turbocharged V-10 engine with 571 bhp and 479 lb-ft. was given a host of upgrades that boosted output to super car levels. The MTM Fostla RS6 Avant was equipped with a new stainless steel exhaust system with racing catalytic converters and adjustable valves on the rear tailpipes for a custom exhaust note, and a retuned ECU. The end result is a whopping 759 horsepower and 673 lb-ft. of torque. This allows the “family car” to rocket to a top speed of 216 mph.

In addition to the engine upgrade, the MTM and Fostla RS6 Avant was given a new set of performance OEM wheels that hide the potent braking system. The original RS6 wheels were removed and replaced with 9.0 x 20 five-spoke wheels from the Audi RS5 and equipped with 275/35 R20 performance tires for added grip. Behind the wheels sit massive 420 mm Audi carbon ceramic brake discs that provide incredible stopping power with virtually no fade.

After the performance tuning specialists at MTM had their way with the V-10 powered wagon, Fostla took on the exterior design. On the RS6 Avant, Fostla installed an anodized matte blue foiling on the entire exterior along with a matte grey strip along the bottom of each side with both company’s logos. Both the front and rear lights were given a slight five-percent tint for a more aggressive appearance. The finishing touches were a carbon fiber front lip and rear diffuser to improve downforce at higher speeds.

All of the upgrades on MTM Fostla RS6 Avant can be purchased from both companies. The Fostla exterior wrapping is available 2,500 Euro, while pricing on the MTM upgrades has not been released.
