About the 2020 Mercedes-Benz AMG GLC
First-generation GLC (X253 SUV/C253 Coupe), mid-cycle refresh year
The AMG GLC turns Mercedes-Benz’s compact luxury SUV into a high-performance daily driver without giving up five-seat usefulness, a power liftgate, or all-weather AWD. The range pairs an everyday-friendly V6 in the GLC 43 with hand-built V8 power in the GLC 63 models. Adaptive air suspension, strong acceleration, rear-biased handling, and a well-finished cabin distinguish it from ordinary compact luxury SUVs, while SUV and Coupe body styles serve different practicality priorities.
The 2020 AMG GLC ranged from the everyday-focused GLC 43 to the 469-hp GLC 63 and 503-hp GLC 63 S. The GLC 43 paired a twin-turbo V6 with rear-biased AWD, while the GLC 63 models used hand-built twin-turbo V8s, variable-torque AWD, adaptive air suspension, and a performance exhaust. The GLC 63 S was the most performance-focused version and came to the U.S. only with the Coupe's sloped roof.
What changed, by category
Powertrain
The GLC 43's twin-turbo V6 rose from 362 to 385 horsepower. The GLC 63 and GLC 63 S kept their prior output ratings but gained AMG DYNAMICS handling control, a Slippery setting, and a standard electronic rear differential across the V8 range.
Styling
The AMG GLC received a revised grille, front and rear bumpers, LED headlights, and LED taillights. The GLC 63 models also gained a new AMG steering wheel.
Safety
Blind Spot Assist with an exit warning became standard across the GLC range.
Tech
A new 10.25-inch touchscreen with the MBUX interface and natural-language voice control replaced the previous setup. Apple CarPlay and Android Auto also became standard.

“Great styling. Incredible performance. Perfect size. Awesome sound (from exhaust system) and the premium audio system.”
