INTRODUCTION
The AMG GLC 63, launched in 2019 as part of the X253 facelift, is a performance-oriented SUV built by Mercedes-AMG, the high-performance division of Mercedes-Benz. It builds upon the standard GLC SUV, offering significantly enhanced power, handling, and styling. This model year marked a substantial upgrade over its predecessor, incorporating the latest AMG technology and design cues. The GLC 63 aimed to deliver a thrilling driving experience without sacrificing the practicality and comfort expected of a luxury SUV. It was available in both SUV and Coupe body styles, with the powertrain remaining consistent across both.
Powertrain & Engine Architecture
At the heart of the AMG GLC 63 lies the M177 DE 40 AL 4.0-liter twin-turbocharged V8 engine. This engine, a cornerstone of AMG’s modern lineup, produces 476 horsepower and 650 Nm (479 lb-ft) of torque. The engine utilizes direct fuel injection and features a ‘hot-vee’ configuration, where the turbochargers are positioned within the V of the engine, resulting in a more compact design and improved responsiveness. The engine’s code, M177, signifies its place within AMG’s engine family. The 9-speed MCT (Multi Clutch Technology) automatic transmission is specifically tuned for performance, offering quick and precise gear changes. Unlike a traditional torque converter automatic, the MCT uses a wet clutch pack, contributing to faster shifts and a more direct feel. The 4MATIC+ all-wheel-drive system is fully variable, intelligently distributing torque between the front and rear axles for optimal traction and handling.
Driving Characteristics
The AMG GLC 63 delivers a remarkably dynamic driving experience. The combination of the powerful V8 engine and the responsive MCT transmission results in blistering acceleration – 0 to 60 mph in approximately 3.8 seconds. The 4MATIC+ system provides excellent grip, allowing for confident cornering and stability in various conditions. The AMG-tuned suspension, featuring adaptive dampers, strikes a balance between comfort and control. While not as overtly track-focused as some other AMG models, the GLC 63 offers a surprisingly engaging driving experience for an SUV. Compared to lower-powered GLC variants, the 63 provides a significantly more visceral and exhilarating experience, with a more aggressive exhaust note and a more immediate throttle response. The 9-speed transmission, while offering a wide range of gears for efficiency, is primarily geared towards performance, with quicker downshifts and a more sporty feel.
Equipment & Trim Levels
The AMG GLC 63 came generously equipped as standard. Interior features typically included AMG sport seats upholstered in Nappa leather, a flat-bottom AMG steering wheel, and brushed aluminum or carbon fiber trim. The infotainment system featured a large central display screen with Mercedes-Benz’s MBUX interface, offering navigation, smartphone integration, and a range of vehicle settings. Standard safety features included automatic emergency braking, lane keeping assist, and blind spot monitoring. Optional extras included a panoramic sunroof, a premium Burmester sound system, and advanced driver-assistance features like adaptive cruise control with stop-and-go functionality. The interior design emphasized a sporty and luxurious aesthetic, with a focus on high-quality materials and meticulous craftsmanship.
Chassis & Braking
The AMG GLC 63 features a specifically tuned chassis to handle the increased power and performance. The suspension utilizes AMG Ride Control, an adaptive damping system that allows the driver to adjust the firmness of the ride. Larger brakes, with ventilated discs at all four corners, provide ample stopping power. The front brakes typically measure 390mm in diameter, while the rear brakes measure 360mm. The braking system is further enhanced by AMG’s high-performance brake pads and calipers. The vehicle’s weight distribution is carefully balanced to optimize handling and stability. The standard tire size is 235/55 R19 for the front and 255/50 R19 for the rear, providing a good balance of grip and ride comfort.
Market Reception & Comparison
The AMG GLC 63 was generally well-received by automotive critics, praised for its powerful engine, responsive handling, and luxurious interior. However, some reviewers noted that its fuel economy was relatively poor, as expected for a high-performance SUV. Compared to other GLC variants, the 63 commanded a significant price premium, reflecting its higher level of performance and equipment. Against rivals like the Porsche Macan Turbo and the BMW X3 M, the GLC 63 offered a compelling combination of performance, luxury, and practicality. Its fuel consumption, averaging around 12.2-12.4 l/100km, was comparable to its competitors, but its CO2 emissions were relatively high.
Legacy
The AMG GLC 63 (X253) represents a significant step forward in the evolution of Mercedes-AMG’s performance SUVs. The M177 engine has proven to be a robust and reliable powerplant, and the 9-speed MCT transmission has generally held up well over time. On the used car market, these models hold their value relatively well, particularly those with low mileage and a well-maintained service history. While maintenance costs are higher than those of standard GLC models, the AMG GLC 63 continues to appeal to enthusiasts seeking a high-performance SUV with a luxurious interior and a thrilling driving experience. Its blend of power, practicality, and prestige ensures its continued desirability in the years to come.
