2019 Mercedes-AMG GLC 63 S Coupe Performance Review

The 2019 Mercedes-AMG GLC 63 S Coupe stands out as a benchmark in the high-performance SUV segment, delivering **supercar-level acceleration** in a stylish, practical package. Powered by a hand-built 4.0-liter twin-turbo V8 engine producing 503 horsepower and 700 Nm of torque, it sprints from 0-62 mph in just 3.8 seconds, rivaling sports cars from a decade ago.

Engineering Excellence Under the Hood

At the heart of this beast is Mercedes-AMG’s signature **4.0-liter V8**, with twin turbos nestled between the cylinder banks for rapid response. The S variant ups the ante with 503 bhp (versus 469 bhp in the base GLC 63), paired to a 9-speed AMG Speedshift MCT transmission. This setup ensures seamless shifts, with faster upchanges under full throttle and multiple downshifts for overtaking.

The **AMG Performance 4MATIC+ all-wheel-drive system** intelligently distributes torque, sending up to 100% to the rear wheels for dynamic handling. An electronic limited-slip differential enhances cornering grip, while dynamic engine mounts and AMG Ride Control+ air suspension adapt to driving modes like Comfort, Sport, Sport+, and Race.

Official Mercedes-Benz data confirms these figures, with real-world tests matching claims closely.

Dynamic Driving Experience

On the road, the GLC 63 S Coupe feels alive, with relentless acceleration that pins occupants back into seats. The V8’s flexibility shines across revs, delivering explosive mid-range punch ideal for highways or twisty roads.

Handling defies its 2,000+ kg weight: a wider front track (41mm more than standard GLC), adaptive dampers, and precise steering make it carve corners sharply. In Sport+ mode, throttle response sharpens, and the chassis exhibits impressive body control, though it’s no lightweight sports car.

• Strengths: Staggering straight-line speed, confident grip in all conditions, intuitive drive modes.
• Challenges: Some transmission hesitation in Comfort mode post-cold start, firm ride over rough surfaces.

Reviewers note the optional AMG Performance Exhaust amplifies the V8’s growl, adding theater without overwhelming.

Striking Exterior Design

The Coupe’s **sloping roofline** gives it a sportier silhouette than the standard GLC, with aggressive AMG styling: wider fenders, prominent Panamericana grille, slim LED headlights, and quad 90mm exhaust tips. Optional 21-inch wheels fill the arches, enhancing its menacing stance.

Available in SUV or Coupe body styles, the latter prioritizes aesthetics over max practicality but retains a commanding road presence.

Luxurious Yet Sporty Interior

Inside, the cabin blends **premium materials** with performance focus. Alcantara-wrapped, flat-bottom steering wheel with touch-sensitive controls, carbon fiber accents, and sport seats in leather with contrasting stitching create an AMG atmosphere.

The updated MBUX infotainment features dual 12.3-inch screens, customizable digital gauges with AMG displays, and voice-activated controls. Rear space suits adults under 6ft, but headroom is tight due to the roofline; boot offers 500 liters.

Safety tech abounds: autonomous emergency braking, adaptive cruise, lane keep assist, blind-spot monitoring, and nine airbags.

Practicality and Everyday Usability

Despite its fire-breathing nature, the GLC 63 S Coupe handles daily duties. The air suspension smooths commutes in Comfort mode, and 4MATIC+ provides surefooted traction in rain or snow.

Fuel thirst is a trade-off at ~11-12 L/100km combined, typical for its power. Pricing started around $110,000-$120,000, positioning it as a premium choice.

It outpaces rivals like the Alfa Romeo Stelvio Quadrifoglio in sprints while offering superior refinement. Compared to Jaguar F-Pace SVR, it trades some soundtrack drama for tech sophistication.
