Mercedes-Benz unveiled a redesigned GLC-Class in early June, which we’ll be seeing in showrooms shortly as a 2023 model. The handsome crossover will eventually spawn new AMG-engineered GLC 43 and GLC 63 performance options, and prototypes for the GLC 63 have been spotted.
The current GLC 63 and the spicier GLC 63 S are Motor Authority favorites, thanks to their rugged looks, track-tuned suspension and, of course, that V-8 lump under the hood.
For the redesigned GLC 63, the V-8 is replaced with a sophisticated plug-in hybrid powertrain that relies on a 4-cylinder engine for its internal combustion component. The new setup, characterized by new E Performance branding, made its debut in a restyled C 63 S, now branded as the C 63 SE Performance. The electrified sports sedan will be available next summer as the 2024 model. Keep an eye out for this new GLC 63 SE Performance that will also be available for 2024.
In the C 63 SE Performance, the 4-cylinder is an improved version of the 2.0-liter turbo-4 found in AMG’s current generation of compact cars. Thanks to the addition of an electrically assisted turbocharger, the engine’s output is boosted to 469 hp. There’s also an electric motor integrated with the engine in a mild hybrid configuration to power ancillary functions and act as a starter.
There is also a significantly more powerful engine (up to 201 hp) on the rear axle, which means that the combined output can be increased to up to 671 hp for short stints. This rear engine is paired with its own 2-speed gearbox. A battery with a capacity of 6.1 kilowatt hours ensures that a small electric range will be possible. Unfortunately, all the new hardware adds about 780 pounds to the outgoing C 63.
A similar setup, albeit with a more powerful V-8 engine, can be found in AMG’s recently introduced 2023 S 63 E Performance, as well as the 2023 GT 63 SE Performance.
Like the revised C-Class, there will also be a tamer GLC 43 model from AMG for the revised GLC-Class, the prototype of which can also be seen in the video. It has the round exhaust tips while the GLC 63 SE Performance has the square tips. In the C 43, the same 2.0-litre Turbo-4 as the C 63 SE Performance delivers 402 hp, with a mild-hybrid system, essentially a souped-up starter that also acts as a generator, capable of generating a to deliver a temporary boost of 13 hp in high-load situations. There may also be a GLC 63 E Performance sitting in the middle to replace the current GLC 63, although AMG hasn’t confirmed this. All models should also come in a coupe-like form.
Another upgrade planned for both the GLC 43 and GLC 63 SE Performance should be rear wheel steering.
