Before the insanely expensive Mercedes-AMG One, the AMG GT 63 S 4MATIC+ E Performance is the most powerful road-legal AMG. This alphanumeric soup of a four-door plug-in coupe makes 831 horsepower (620 kilowatts) and 1,033 pound-feet (1,400 Newton-meters) of torque in stock form.
But unlike the complicated AMG One hypercar, which requires an engine rebuild every 50,000 kilometers (about 31,000 miles), the AMG GT 63 SE Performance can be given an aftermarket tune.
Case in point: Opus presents its PHEV Stage 1 performance tuning.

The Nurburgring-based tuner upgrades the AMG GT 63 SE Performance, allowing the electrified model to produce up to 952 hp (710 kW) and 1,143 lb-ft (1,550 Nm) of electronically limited torque. The electronic unit contributes to this with 204 hp (152 kW), while the 4.0-liter M177LS2 V8 develops 748 hp (558 kW).
Of course, those numbers translate into exhilarating performance. Opus claimed a sprint to the centenary mark (62 miles per hour) in just 2.7 seconds from a complete stop – quite a bit quicker than the production model. The 200 km/h (128 mph) mark can be reached in 8.55 seconds, one second faster than in the standard version.
The optimized version is also fast. Opus tested the tuned AMG GT 63 SE Performance on the motorway and was able to clock it at 321 km/h (199 mph), which you can watch through the embedded video at the top of this page.
The Opus-tuned AMG GT 63 SE Performance will be available for purchase in October 2022 after receiving its TUV approval. The company also offers a special exhaust flap control system and an OBD lowering module. In winter, Opus says it will try to break the 1,000 horsepower barrier, although the tuner admits that will be difficult compared to non-hybrid AMGs.
