O hne question: For everyone who Longing for even more power in the Mercedes-AMG GT S, the Affalterbach-based sports car specialist will cobble together a GT3 variant next year. And for those who do not want to or cannot be patient, Tuner Performmaster already has a first remedy ready. This transforms the GT S into a Porsche 911 Turbo S conqueror.

Acceleration at Porsche 911 Turbo S level

With the installation of the power box, the output of the four-liter V8 biturbo, known internally as the M 178, increases to 612 hp and 780 Nm. That is a plus of 130 Nm and 102 PS - or in other words: almost the additional power of a Mercedes A 180 CDI.

The resulting performance is almost on the same level as the Porsche 911 Turbo S from our super test. The tuned Mercedes-AMG GT S takes 3.6 seconds from 0 to 100 km /h, two tenths less than the base. On the all-wheel drive 911, however, the tuning object is missing half a second.

That changes during the sprint to 200 km /h; The Performmaster GT S achieves this in 10.2 seconds - i.e. only two tenths slower than the high-performance 911 Turbo S, which we measured on the test bench with 607 hp and sometimes 784 Nm.

Performmaster promises tuning without regrets

At top speed, the tuning GT S gives the Porsche no chance: Performmaster promises 330 km /h, the Turbo S is 318 km /h. The specialty of tuning: the manufacturer promises 24 Months or 100,000 kilometers guarantee on the complete motor-gearbox unit, with no upper limit. The price for the complete Performmaster package is 4,998 euros, with TÜV-compliant parts certificate. Available from August 2015.
