After Senner Tuning's recent take on the Audi A7 Sportback TDI, MTM is next in line to offer its services to the diesel-powered model.

In regular factory trim, the A7's 3.0-liter V6 turbocharged diesel engine churns out 245-horses and 500Nm (369 lb-ft) of peak torque. The German tuning firm offers buyers two different options, the first pushing output to 285HP and peak torque to 580Nm (427.8 lb-ft), and the second to 300-horsepower and 600Nm (442.5 lb-ft) respectively.

Among the many tuning firms making their way to the Geneva Motor Show is VW Group specialist MTM. The German company will display two heavily modified Audi models, based on the R8 V10 and the TT RS. The most impressive proposal is the one-off MTM R8 Biturbo that comes with a polished chrome body that took over 700 working hours to complete. A large fixed spoiler at the back along with 20-inch forged rims and carbon fiber parts round off the exterior changes.
