Mercedes-Benz has announced the arrival of the 2027 Mercedes-AMG GLC53 4Matic+, a new high-performance version of its compact crossover that will replace the previous GLC63 plug-in hybrid model. The new GLC53 features a 3.0-liter six-cylinder engine producing 443 horsepower and 443 lb-ft of torque, a significant decrease from the outgoing four-cylinder PHEV's combined output of 671 hp. However, Mercedes is hoping the simpler, lighter powertrain will result in improved driving dynamics compared to the heavier PHEV.

Why it matters

The shift from a powerful four-cylinder PHEV to a six-cylinder non-hybrid model represents a significant change in philosophy for Mercedes-AMG's high-performance crossover lineup. While the new GLC53 will be slower in a straight line, the automaker is betting that the lighter, more engaging driving experience will appeal to enthusiasts who were underwhelmed by the outgoing GLC63's complex hybrid powertrain.

The details

The 3.0-liter six-cylinder engine in the GLC53 is shared with other AMG models like the CLE53 coupe and convertible. It produces 443 hp and 443 lb-ft of torque, with an additional 472 lb-ft available in short bursts via an overboost function. This represents a notable decrease from the 671 hp combined output of the previous GLC63 PHEV. As a result, the 0-60 mph time increases from 3.5 seconds to 4.1 seconds. However, Mercedes is betting that the lighter, simpler powertrain will translate to a more enjoyable driving experience.

What they’re saying

“We won't be able to figure out if the adjustment pays off until we climb behind the wheel, but the move to a lighter and simpler system should make for a more enjoyable crossover—even if it is a tad slower.”

The takeaway

Mercedes-AMG's decision to replace the powerful but complex GLC63 PHEV with the simpler, lighter GLC53 6-cylinder model represents a shift in priorities, prioritizing driving dynamics over raw power. While the new GLC53 will be slower in a straight line, the automaker is betting that enthusiasts will appreciate the more engaging and enjoyable driving experience.
