Before the expensive Mercedes-AMG One, the AMG GT 63 S 4MATIC + E Performance was the most powerful street-legal AMG. This alphanumeric stew for the four-door coupe makes 831 electric horsepower and 1,033 pound-feet of torque in stock form.
But other than that it’s complicated AMG Ones The supercar, which requires an engine overhaul every 31,000 miles, can get a Performance AMG GT 63 SE aftermarket tune. Case in point: the Opus PHEV offers Stage 1 performance tuning.
The Nurburgring-based tuner boosts the performance of the AMG GT 63 SE, allowing the electrified model to produce 952 horsepower and 1,143 pound-feet of electronically limited torque. The electric unit contributes 204 hp, while the M177LS2 V8’s 4.0-liter engine produces 748 hp.
Of course, these numbers add up to a pleasing performance. The Opus claims a sprint from standstill to 100 km/h in just 2.7 seconds – boy Faster than the production model. The 128 mph mark is reached in 8.55 seconds, a second quicker than in stock form.
The modified version is also faster. Opus tested the performance of a highway-tuned AMG GT 63 SE and scored a top speed of 199 mph, which you can see in the video embedded at the top of this page.
The performance-enhanced AMG GT 63 SE Opus will be available for purchase in October 2022 after receiving TÜV approval. The company also offers special exhaust flap control and OBD mitigation. Opus says it will try to break the 1,000 hp barrier this winter, though the tuner admits it will be harder than non-hybrid AMGs.
