The AMG GLC 63 4MATIC+ MCT, launched in 2017, represented Mercedes-AMG’s foray into the burgeoning performance SUV segment. Built on the X253 GLC platform, it distinguished itself from the standard GLC models through its potent engine, upgraded suspension, and aggressive styling cues. The “MCT” designation refers to the Multi Clutch Technology utilized in its nine-speed automatic transmission, a key component in delivering rapid and smooth gear changes. This vehicle aimed to provide a compelling alternative to traditional sports cars, offering practicality and space without sacrificing driving excitement.
Powertrain & Engine Architecture
At the heart of the GLC 63 lies the M177.980 4.0-liter twin-turbocharged V8 engine. This engine, a cornerstone of AMG’s modern powertrain lineup, utilizes direct fuel injection and a ‘hot-vee’ configuration, where the turbochargers are positioned within the V of the engine block. This design minimizes exhaust gas routing, improving turbocharger response. The engine produces 476 horsepower at 5,500-6,250 rpm and a substantial 650 Nm (479 lb-ft) of torque available from a low 1,750 rpm all the way to 4,500 rpm. The MCT 9-speed automatic transmission, a modified version of the 9G-TRONIC, features a wet multi-disc clutch pack instead of a traditional torque converter, enabling quicker shifts and a more direct connection to the engine. This transmission is specifically tuned for performance applications, with shorter gear ratios and enhanced shift logic.
Driving Characteristics
The GLC 63 delivers a remarkably dynamic driving experience for an SUV. The twin-turbo V8 provides effortless acceleration, with the 0-60 mph sprint achievable in around 3.8 seconds. The MCT transmission contributes to this performance with its rapid and precise gear changes. While the vehicle’s weight (approximately 4,244 lbs) is noticeable, the AMG-tuned suspension and standard air suspension system effectively mitigate body roll and provide a surprisingly agile feel. The 4MATIC+ all-wheel-drive system intelligently distributes torque between the front and rear axles, optimizing traction in various conditions. Compared to the standard GLC models, the GLC 63 offers a significantly more aggressive throttle response, firmer steering feel, and a more engaging overall driving experience. It differs from the GLC 43 AMG, which uses a smaller V6 engine, by offering substantially more power and a more visceral exhaust note.
Equipment & Trim Levels
The AMG GLC 63 came generously equipped as standard. Interior features included sport seats upholstered in Nappa leather with AMG badging, a flat-bottom steering wheel, and aluminum paddle shifters. The dashboard featured AMG-specific instrumentation and a high-resolution infotainment system with navigation. Standard exterior features included AMG body styling, a performance exhaust system, and 19-inch alloy wheels. Numerous options were available, including a panoramic sunroof, upgraded audio system, head-up display, and various interior trim packages. The interior ambiance was focused on sporty luxury, with a clear emphasis on driver engagement.
Chassis & Braking
The GLC 63’s chassis was extensively modified by AMG to enhance handling and stability. The suspension system featured AMG Ride Control with adaptive damping, allowing drivers to adjust the firmness of the suspension to suit their preferences. The vehicle utilized a multi-link suspension setup at both the front and rear axles, optimized for performance driving. Braking duties were handled by large, ventilated discs with AMG-branded calipers, providing ample stopping power. The braking system was further enhanced by ABS (Anti-lock Braking System) and other electronic stability control systems.
Market Reception & Comparison
The AMG GLC 63 was generally well-received by automotive critics, who praised 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 rivals like the Porsche Macan Turbo and BMW X3 M, the GLC 63 offered a compelling combination of performance, luxury, and practicality. The GLC 63 often stood out for its more comfortable ride quality compared to some of its more track-focused competitors. Reliability reports have been generally positive, although the complexity of the engine and transmission systems means that maintenance costs can be higher than those of standard GLC models.
Legacy
The AMG GLC 63 established itself as a popular choice in the performance SUV segment. The M177 engine proved to be robust and reliable when properly maintained. On the used car market, the GLC 63 commands a premium price due to its performance capabilities and AMG pedigree. While newer iterations of the GLC have been released, the X253 generation GLC 63 remains a desirable vehicle for enthusiasts seeking a blend of luxury, performance, and practicality. Its combination of a powerful V8 engine, advanced transmission technology, and sophisticated chassis tuning continues to appeal to buyers today.
