The redesigned Mercedes-Benz GLE class debuted as a 2020 model, and since then, Mercedes has been adding to the lineup. It once again offers a “Coupe” body style with a more sloped roofline and an exclusive 5-seat interior. Both coupe and standard SUV have AMG sporty trims. A Mercedes-AMG 53 version of the coupe already has been introduced, and last fall Mercedes introduced the top AMG GLE 63 S variant of the SUV. Now comes its coupe counterpart: the 2021 Mercedes-AMG GLE 63 S Coupe. Both are the ultimate expression of performance in a mid-size Mercedes SUV.
Mechanical twin to the GLE 63 S SUV
If you’re familiar with the mechanical workings of the GLE 63 S SUV, then you know what motivates the new GLE 63 S Coupe. Under the hood is a 4.0-liter bi-turbo V8 making 603 horsepower and 627 lb-ft of torque. Both figures are notable increases from the previous, 2019 GLE 63 S Coupe, which mustered 577 horses and 561 lb-ft.
The new Coupe’s stated 0-to-60-mph time is 0.4-second quicker than that of the outgoing model. Now 3.7 seconds, the Coupe’s 0-60 time and its top speed of 174 mph exactly match those of the regular GLE 63 S.
All-wheel drive with a 9-speed automatic
The 4.0-liter V8 and 9-speed automatic transmission pair with standard 4Matic+ all-wheel drive. The AWD system sends up to 100 percent of the engine’s torque to the rear axle, which features an electronic limited-slip differential. A 48-volt mild-hybrid system contributes an additional 21 horsepower and 184 lb-ft of torque in brief bursts.
The 48-volt system also powers the suspension’s active anti-roll bars, and other special chassis features include adaptive dampers, air springs, and active engine mounts. Among the standard drive modes is a RACE setting exclusive to the 63 S. In the RACE, Sport, and Sport+ modes, the air suspension automatically lowers the vehicle’s ride height. Conversely, the Trail and Sand modes raise the ride height for additional ground clearance at speeds below 43 mph.
The standard front brake rotors are 15.7 inches in diameter, while the rears are 14.6 inches, both squeezed by red brake calipers. Optional carbon-ceramic brake rotors sport bronze-colored calipers.
In its appearance, the GLE 63 S Coupe shares some elements with its AMG GLE 53 Coupe counterpart. Both feature AMG’s vertical-bar “Panamericana” grille, air intakes carved into the lower fascia, dual power domes on the hood, side skirts on the lower body. Outlined in chrome, the rear diffuser houses rectangular exhaust outlets. The 22-inch wheels are standard, while an optional Night Package adds black trim and dark-tinted windows.
Inside, the AMG-specific seats are upholstered in special Nappa leather with AMG logos. The AMG 3-spoke steering wheel is wrapped in Nappa leather and microsuede with a black hash mark at 12 o’clock, and features controls for the drive modes. The MBUX dual-screen display features exclusive AMG graphics, including a Supersports instrument cluster with a central tachometer and upshift lights for the transmission’s manual mode.
Arrival and rivals
The 2021 Mercedes-AMG GLE 63 S Coupe reaches dealerships this fall, trailing its SUV counterpart by a few months. Among its rivals are the Audi (the SQ8), BMW (the X6 M and X6 M Competition), and Porsche (the Cayenne Turbo and Turbo S E-Hybrid Coupe). Pricing for the 2021 GLE 63 S Coupe has not been announced. But, the previous (2019) model was $113,000 before destination. We wouldn’t expect this new one to sell for a penny less.
