Renntech Upgrade Gives Mercedes-AMG GT63 Four-Door 1,196 Horsepower

Exciting news for Mercedes-AMG GT63 4-Door Coupe owners! Renntech has just released a new upgrade for your vehicle, called RIIIX. It's a fascinating name for the product. The upgraded twin-turbocharged 4.0-liter M177 V8 engine, is now boasting a staggering 1,196 horsepower and 927 pound-feet of torque.

That's a significant increase from the already impressive stock model's 681 hp and 736 lb-ft of torque. 

The package comes equipped with Stage II high-performance turbochargers, a re-mapped ECU, a carbon-fiber air intake system, high-pressure fuel pumps, and other exciting tweaks that will take your driving experience to the next level. The output reduces when the fuel type changes. Only 100 octane gas is compatible with the 1,100 horsepower. The engine's output decreases to 965 horsepower and 917 lb-ft of torque on 93 octane.

Buckle up, because the  Mercedes-AMG GT63 Four-Door is a speed demon with all-wheel drive that can go from 0 to 60 miles per hour in a jaw-dropping 2.44 seconds. And if that's not impressive enough, it can hit 100 mph in a mere 5.5 seconds with the upgrades. The tuner's carbon-fiber aerodynamic package also includes a front splitter, front canards, two-piece side skirts, a rear diffuser, and an adjustable rear wing - all designed to enhance the car's performance and give it a sleek, sporty look. 

In addition, the exhaust system has been upgraded with stainless steel components, such as downpipes and performance mufflers equipped with 200-cell catalytic converters. The Mercedes-AMG GT63 Four-Door  sports 21-inch front and 22-inch rear Renntech RPS 10.2 forged aluminium wheels. They arrive with Michelin Pilot Sport 4S tyres on. According to Renntech, the RIIIx package is exclusive and costs $94,980 (not including the price of the vehicle).
