Earlier this year, Mercedes-Benz had been so fortunate so as to launch the second-generation GLC-Class with a turbocharged engine that came equipped with a 2.0-liter four-cylinder with help from a 48-volt hybrid system. Of course, with the success of that car, Mercedes shows further interest by allowing the GLC-Class to meet AMG specs. The GLC43 will be forever seen, therefore, as a lily pad for the high-octane GLC63 S E Performance model to vroom in, just in time for 2025’s model year. But what’s the catch? The engine swapped in is a hybrid four-cylinder setup.

Beneath the hood, the 2025 Mercedes-AMG GLC63 is just as powerful as the latest and greatest sedan!

Of course, the incredible thing about the hybrid engine is that it utilizes the creme de la creme in propulsion. On the electric side, you have a rear-mounted 201-horsepower motor, shifting through a two-speed transmission, without fail. On the internal combustion engine, you can drive in awe of the force that comes through in the 469-horsepower M139 turbocharged 2.0-liter inline-four that is directly tied to the nine-speed wet-clutch transmission. It’s really quite incredible, as the system itself can propel a combo of 671 horsepower, mixed in with about 752 pound-feet of torque, with impressive upgrades beyond the former V-8’s very own 469 horsepower, with 479 pound-feet. Additionally, the sprint of zero to sixty miles per hour only takes a whole 3.4 seconds, while the top speed is electronically capped at 171 miles per hour.

When taking a look at the turbocharger on the M139 engine, there’s an electric motor that gets rid of turbo lag, thanks to the connection made between the compressor and the turbine wheels, which make it simple to spool the turbo right before the exhaust gases come into play.

Mercedes themselves haven’t quite yet admitted where the range would land, but they did specify that the GLC63 would utilize the strength emanating from the 6.1-kilowatt hours lithium-ion battery that rests right above the rear axle. Such power can come straight from the electric motor, as the front wheels can be given more traction when needed, while the e-motor has a second gear engaging total action of up to 87 miles per hour. Not to mention, rear-wheel steering is included for the best of luck. That way, the GLC 63 can be much more nimble and quick, while the upgraded brakes will allow for total avoidance of collision impact.
