There it is in full view for everyone to see.
We've know for a while that the next-generation 2023 Mercedes-AMG C63 Sedan will downgrade from a twin-turbocharged V8 to a turbocharged four-cylinder. Though it will only have half the cylinders, the new C63 will gain a plug-in hybrid system offering far more power than the outgoing model. Our spy photographers have caught the C63 out testing wearing heavily camouflage, but it looks like Mercedes is no longer trying to hide the car as-evidenced by this display at the 2022 Goodwood Festival of Speed.
The C63 AMG was on full display rocking the same grey, red, and white E Performance livery that's been shown off on previous cars. This livery leaves very little to the imagination, giving us our best look yet at AMG's newest BMW M3 rival. Even the performance figures aren't a secret anymore.
According to the spec sheet displayed next to the car, the C63 E Performance will have a 2.0-liter turbocharged four-cylinder engine tuned to produce 473 horsepower on its own. For reference, that's the exact same amount BMW squeezes out of the M3's twin-turbo inline-six. With the electric motor factored in, the AMG will blow the M3 out of the water with 670 hp and 553 lb-ft all going to the rear wheels. Perhaps it won't sound as good as the old V8, but the hybrid setup outmatches even the BMW M5 and the Mercedes-AMG E63.
The C63 E Performance will get a smaller battery than other Mercedes plug-in hybrid models, likely to keep the weight down. It will only boast a 6.1-kWh battery pack compared to the 25.4-kWh battery in the C300e. That car will travel around 62 miles (on the WLTP cycle) so we expect the C63 to only eek around 10 to 15 miles out of its battery.
We look forward to seeing the final specs, but this latest appearance gives us our best glimpse of the updated styling. The C63 looks more aggressive than the lesser C43 with more substantial side air intakes, lower front air opening, larger wheels and brakes, a more substantial rear spoiler, and square AMG quad exhaust tips. With Mercedes showing off this much of the car at public events, we suspect a full reveal can't be far away. When the C63 E Performance arrives on the market, Audi and BMW are going to have a tough time competing with this hybrid giant. Expect a price tag of around $80,000.
