Previously, only the AMG 63 S Coupe was available in America.
While we're still waiting for the next-generation Mercedes GLC to arrive, the US version of the range-topping Mercedes-AMG GLC 63 S has finally debuted for the 2022 model year by popular demand to battle the BMW X3 M Competition and Porsche Macan Turbo S.
Like the regular GLC 63, the S variant is powered by a 4.0-liter twin-turbo V8, uprated to produce 503 horsepower and 516 lb-ft of torque. Previously, this more powerful unit was reserved for the GLC 63 S Coupe in America. All that power is sent to an all-wheel-drive system with variable torque distribution through a nine-speed automatic transmission.
While this is the first time it has been available in America, the GLC 63 S has been on sale in Europe since 2018, when it set a new SUV lap record at the Nurburgring with a time of seven minutes and 49.36 seconds.
Since then, the GLC 63 S has been overtaken by the Audi RS Q8, which is still the SUV king of the Nurburgring after it lapped the famous German circuit in seven minutes and 42.2 seconds. Even so, the AMG GLC 63 S is still one of the fastest SUVs in its class: 0-60 mph takes just 3.6 seconds before it maxes out at an electronically limited 174 mph. Thanks to an AMG Performance exhaust system with adjustable flaps, the twin-turbo V8 powering the AMG GLC 63 S growls with more ferocity. 20-inch wheels are also fitted as standard.
Inside, the AMG GLC 63 S features a 12.3-inch digital instrument cluster and a 10.25-inch touchscreen display with the latest MBUX infotainment system featuring unique functions and displays specific for the AMG model.
Slotting below the AMG GLC 63 S is the AMG GLC 63, detuned to 469 hp and 479 lb-ft, and the AMG GLC 43, which is powered by a 3.0-liter twin-turbo V6 producing 385 hp and 384 lb-ft of torque.
Sales for the 2022 Mercedes-AMG GLC range will start in the US in Q4 2022, with pricing to be announced at a later date. Expect the new range-topper to be more expensive than the standard AMG GLC 63, which starts at $73,900 - don't be surprised if it costs over $100,000.
