INTRODUCTION
The AMG GLC 63 S Coupe, introduced with the 2019 facelift of the C253 generation, is a performance-oriented version of the GLC Coupe. It slots above the standard GLC Coupe models, offering significantly increased power and a more focused driving experience. The “S” designation denotes an even higher level of performance than the base GLC 63 Coupe. This vehicle aimed to appeal to enthusiasts desiring a blend of SUV practicality, coupe styling, and AMG’s signature high-performance characteristics. It competed with rivals like the Porsche Macan Turbo and the BMW X4 M.
Powertrain & Engine Architecture
At the heart of the GLC 63 S Coupe lies the M177 DE 40 AL 4.0-liter twin-turbocharged V8 engine. This engine, a cornerstone of AMG’s performance lineup, produces 510 horsepower and 700 Nm (516 lb-ft) of torque. The engine utilizes direct fuel injection and features a ‘hot-vee’ configuration, where the turbochargers are located within the V of the engine, contributing to a more compact design and improved responsiveness. The engine is paired with AMG’s SPEEDSHIFT MCT 9-speed automatic transmission. “MCT” stands for Multi Clutch Technology, a wet-start clutch system that replaces the traditional torque converter for faster and more direct gear changes. This transmission is tuned for performance, offering quick shifts and a responsive feel.
Driving Characteristics
The GLC 63 S Coupe delivers exhilarating performance. Its 0-60 mph acceleration time of around 3.6 seconds and a top speed of 174 mph (electronically limited) are indicative of its capabilities. The AMG-tuned suspension, featuring adaptive dampers, provides a firm yet controlled ride. The 4MATIC+ all-wheel-drive system is rear-biased, enhancing driving dynamics and providing excellent traction. While the automatic transmission is exceptionally quick, it doesn’t quite match the engagement of a dual-clutch transmission. Compared to the standard GLC Coupe models, the 63 S offers a dramatically more powerful and engaging driving experience. The higher output and sport-tuned components make it a significantly more capable performance vehicle.
Equipment & Trim Levels
The GLC 63 S Coupe comes standard with a comprehensive array of luxury and performance features. These include AMG body styling, a performance exhaust system, AMG sport seats, a panoramic sunroof, and a premium sound system. Interior appointments feature high-quality leather upholstery, carbon fiber trim, and brushed aluminum accents. Standard technology includes Mercedes-Benz’s MBUX infotainment system with a large touchscreen display, navigation, and a suite of driver-assistance features. Optional extras included features like head-up display, advanced driver-assistance packages, and customized interior finishes.
Chassis & Braking
The chassis of the GLC 63 S Coupe is reinforced to handle the increased power and stresses of high-performance driving. The suspension features AMG Ride Control, allowing drivers to adjust the damping characteristics. The braking system consists of large, ventilated discs on all four wheels, with AMG-branded calipers. The front brakes measure 390mm in diameter, while the rear brakes are 360mm. This provides ample stopping power and resistance to fade. The steering is precise and well-weighted, offering good feedback to the driver.
Market Reception & Comparison
The AMG GLC 63 S Coupe was generally well-received by automotive critics. It was praised for its powerful engine, dynamic handling, and luxurious interior. However, some reviewers noted that the ride could be firm, and the fuel economy was relatively poor, as expected for a high-performance vehicle. Compared to the standard GLC Coupe models, the 63 S offered a substantial performance upgrade but came at a significant price premium. Against competitors like the Porsche Macan Turbo, the GLC 63 S Coupe offered a compelling combination of performance, luxury, and practicality.
Legacy
The M177 engine, found in the GLC 63 S Coupe, has proven to be a robust and reliable powerplant when properly maintained. While the complexity of the twin-turbocharged V8 and the AMG-specific components can lead to higher maintenance costs compared to the base GLC models, the engine itself is generally considered durable. On the used car market, the GLC 63 S Coupe holds its value well, appealing to buyers seeking a high-performance luxury SUV. Its combination of performance, style, and technology ensures its continued desirability among enthusiasts.
