It's even more hardcore than the new R version.
Aftermarket specialists have certainly developed a soft spot for the Mercedes-AMG GT in recent months taking into account more and more custom packages are coming out for the high-performance coupe. The latest example is from Germany’s Piecha which was able to fiddle with the spicy mid-range S version of the lineup.
The first order of business was to customize the exterior by giving the fast-paced machine some aero bits and pieces made from carbon fiber to keep the weight low. Work started with the front fascia where Piecha has added a prominent splitter while the generous air vents feature new carbon fins to further boost the visual impact. The side profile has remained almost intact, with the exception of the tuner’s new 19-inch front & 20-inch rear alloy wheels and prominent side skirts to make the car seem wider and more aggressive.
Without any doubt, the most striking changes are noticeable at the back where the GT S now features a beefy diffuser incorporating the new quad exhaust tips along with a massive wing to increase downforce at the axle. The fixed rear wing is actually an addition to the supercar taking into account the standard retractable spoiler is still there to fulfill its duties.
It would not be a complete tuning job without some work underneath the hood where Mercedes-AMG’s biturbo 4.0-liter V8 engine resides. In the standard ‘S’ model, the eight-cylinder mill pushes out 510 horsepower (375 kilowatts) and 480 lb-ft (650 Newton-meters) of torque, but Piecha worked its magic and dialed the V8 to a healthy 612 hp (450 kW) and 620 lb-ft (840 Nm). That’s even more than the range-topping Mercedes-AMG GT R that came out recently.
With the power package in place, the tuned GT S will run to 62 mph (100 kph) in 3.7 seconds and reach a respectable maximum speed of 205 mph (330 kph). Even though it has more power than the R version (585 hp / 430 kW & 516 lb-ft / 700 Nm), it’s still a tenth of a second slower in the sprint, but on the other hand the tuned model’s top speed eclipses the R’s 198 mph (318 kph).
