The Mercedes-AMG GT 63 4-Door Coupe is the sports carmaker’s flip coin. On the one side, it looks like the perfect family car. On the other hand, it can shed some rubber on the racetrack as well. The figures that it comes with give it credit. But what if those figures are not enough?
This is where Renntech comes in. The tuners got their hands on a Mercedes-AMG GT 63 4-Door Coupe and this is what came out of them. The 4.0-liter twin-turbocharged V8 gets 1,196 horsepower and 927 lb-ft (1,257 Nm) of torque instead of the standard 681 horsepower and 736 lb-ft, going to both axles via a nine-speed automatic transmission. If there’s anything that can be called “standard” about the GT.
How did they get there? They fitted in the RIIX, a package that brings Stage II high-performance turbochargers, a remapped ECU, high-pressure fuel pumps, and a new carbon-fiber air intake system. There is also a new exhaust system, sporting tailpipes with 200-cell catalytic converters and performance mufflers. Renntech also came up with a Transmission Control Unit to help the gearbox tackle the extra oomph.
The car can now hit 62 mph (100 km/h) from zero in 2.44 seconds. It takes 5.5 seconds to get to 100 mph and completes the quarter mile in 9.9 seconds at 139 mph.
The tuning house could have left the looks out. So they brought on a carbon-fiber aerodynamic package to make it look like a genuine predator. Therefore, the package includes the canards, front splitter, side skirts, air diffuser, and rear wing.
The performance sedan also gets the RIIX badging and runs on Renntech RPS 10.2 forged aluminum 21-inch rims at the front and 22-inch units at the rear, all in Michelin Sport 4S tires.
$94,980 is the price that customers have to pay to take their car to the Renntech shop and then drive home a real beast.
