The high-performance variant of Mercedes’ entry-luxury C-class sedan will return as the C63 S 2024, but this time it will get a very different engine. The previous generation was powered by a twin-turbo 4.0-liter V-8 engine with 469 or 503 horsepower, but the new generation C63 will be powered by a half petrol engine: a turbocharged 2.0-liter four-cylinder that combines with an electric motor to produce a total of 671 horsepower. The new hybrid setup promises to improve on the previous C63’s great performance, although the character of the engine will no doubt change radically. To help reduce turbo lag, the downsized engine uses an electrically powered turbocharger system related to that found in the Mercedes-AMG. Formula 1 car racing. Other packages will be heavily based on new C class debuting for model year 2022 but with a more racist style and tidied up interior. Mercedes-AMG has also confirmed that junior c43 models will also return to the lineup, but we’re reviewing those models separately.
What’s New for 2024?
The C63 is all-new for the 2024 model year and, unlike last year, it will be offered only as a sedan. We expect to see the C63 2024 hit Mercedes dealerships in mid-2023.
Price and Where to Buy
Mercedes-AMG hasn’t released pricing yet but we expect the C63 to follow the new trim levels it launched with the 2022 C class, starting with the base Premium trim at around $85,000 and going up from there.
Engine, Transmission and Performance
Gone is the old twin-turbo V-8 engine from the last-generation C63 and in its place is a turbocharged 2.0-liter four-cylinder. But before you get disappointed with the old half-size engine, you should know that this inline-four will be coupled with a 201-hp electric motor and use an electric turbocharger to reduce turbo lag. The new high-performance hybrid propulsion system will pump out a massive 671 horsepower, giving it an edge over performance sedan rivals such as the BMW M3 and Cadillac CT4-V Blackwing, at least on paper. This setup allows for some limited electric propulsion, but only about 8 miles or so; the goal is to provide performance similar to car out with better overall fuel economy. When we get the chance to test drive the new C63—which we really want to do—we’ll update this story with driving impressions and test results.
Real World Fuel Economy and MPG
The EPA has yet to release fuel economy figures for the 2024 C63 sedan. However due to the introduction of the downsized engine, we expect to see some fuel efficiency improvements over the previous model which is rated at 17 mpg city and 26 mpg highway. When we get the chance, we will use the new C63 sedan our 75 mph highway fuel economy test route and update this story with the results. For more information on C63 fuel economy, visit EPA website.
Interior, Comfort and Cargo
The C63’s cab looks very much like the standard C-class and AMG C43 junior models, but features unique upholstery and stitching patterns and AMG-branded sports seats with cut openings to help save weight. Mercedes hasn’t detailed every feature and option yet, but we expect to see plenty of luxury and comfort available, including a panoramic sunroof, heated and cooled seats, four-zone automatic climate control, and more.
Infotainment and Connectivity
All models will likely come with the same large 11.9-inch infotainment touchscreen integrated into the center console and slightly tilted toward the driver in the C43 model. A 12.3-inch digital gauge display is also likely to be standard. Apple CarPlay and Android Auto should both become the standard for wireless connectivity, and a high-end Burmester stereo system is expected to be available as well.
Safety Features and Driver Assistance
Like the C43, the C63 will likely offer a number of standards driver assistance feature but sadly, the car’s coolest technology, which includes an adaptive cruise control system that uses navigation data to adjust vehicle speed for upcoming turns and roundabouts, will probably remain an optional upgrade. For more information on C43 crash test results, visit the National Highway Traffic Safety Administration (NHTSA) and the Insurance Institute for Highway Safety (IIHS) website. Key security features likely include:
- Standard automatic emergency braking with pedestrian detection
- Departure lane warning is available with the help of a lane guard
- Adaptive cruise control available with lane centering feature
Warranty and Maintenance Coverage
Even though rivals like BMW, Originand Volvo offering three years of free maintenance, Mercedes-AMG takes away the benefits of its standard warranty offer. Otherwise, all new AMGs come with industry standard packages that cover most things for up to four years or 50,000 miles.
- Limited warranty covers four years or 50,000 miles
- Powertrain warranty covers four years or 50,000 miles
- No free scheduled maintenance
