Having just debuted the new Mercedes GLC and GLC Coupe, today the German automaker unveiled AMG-ified versions of both SUVs. Mercedes-AMG GLC43 2024 and Mercedes-AMG GLC63 SE 2025 Performance – deep breath – are two of the most powerful iterations of GLC to date.
The GLC43 remains the group’s “base” AMG, combining a turbocharged 2.0-liter engine with an integrated starter generator to produce 416 horsepower. There’s also an additional 13 horsepower available via a lower speed starter generator.
The mild hybrid powertrain pairs well with a nine-speed multi-clutch transmission and 4Matic all-wheel drive. As in other AMG models such as the E63, the so-called Speedshift MCT gearbox is equipped with a wet start-off clutch – replacing the torque converter – which provides smoother low-speed operation and better full-speed response. Additionally, the GLC 43 gets rear axle steering and standard air suspension with adaptive damping as part of the AMG Ride Control system.
But switching to the GLC63 SE Performance (as with the outgoing GLC, no 53 model) doesn’t get you a V8. Instead, the turbocharged 2.0-liter four-cylinder engine works with a rear-mounted electric motor to produce 671 hp and 752 pound-feet of torque. The turbocharged engine produces just 469 hp and 402 lb-ft – which makes it the most powerful four-cylinder engine in the world. The electric motor produces 201 hp.
For 60 miles per hour, the GLC63 SE Performance takes just 3.4 seconds. Top speed is electronically limited to 171 mph. And like the GLC43, the 63 uses the same nine-speed multi-clutch transmission and features standard 4Matic all-wheel drive. But the 4Matic+ system on the 63 is fully variable, meaning it can send up to 100 percent of the available power to the rear wheels.
The visual upgrade between these two AMG models and their standard Benz counterparts should be obvious. A unique grille with vertical slats is the biggest differentiator, while larger air intakes and more chrome accents grace the front ends of both cars. At the rear, the GLC 43 features rounded twin exhaust pipes while the GLC 63 opts for a trapezoidal look.
The interior is much better, with standard MB-tex and microfiber cabins or the option of full Nappa leather with an embossed AMG logo on the front headrests. Buyers looking for something sportier can opt for the Performance seats.
The same MBUX system found in the base GLC is carried over to the AMG models – but now with AMG-specific features. The instrument cluster, center display and optional head-up display have dedicated AMG graphics, with AMG Track Pace embedded in the infotainment system for data logging should you decide to take one of these SUVs to the track.
The 2024 Mercedes-AMG GLC 43 SUV goes on sale first, arriving at US dealerships early next year. No word on price. The Mercedes-AMG GLC 63 SE Performance will be sold as a 2025 model, meaning it won’t appear in US dealerships until the end of 2024. No word on pricing for the 63 model either.
