Powertrain & Engine Architecture
At the heart of the AMG GLC 63 S lies the M177.980 4.0-liter V8 engine. This engine, a staple in many AMG models, utilizes a ‘hot-vee’ configuration, meaning the turbochargers are located within the V of the engine, resulting in a more compact design and improved responsiveness. The engine employs direct fuel injection and twin turbochargers, generating a formidable 510 horsepower and 516 lb-ft of torque. The engine’s output is managed by a sophisticated engine control unit (ECU) that optimizes performance based on driving conditions. The engine is paired with AMG’s SPEEDSHIFT MCT 9-speed automatic transmission. This transmission utilizes a wet multi-plate clutch pack instead of a traditional torque converter, offering faster and more direct gear changes. The MCT transmission is tuned for performance, with quick shifts and a responsive feel.
Driving Characteristics
The AMG GLC 63 S delivers exhilarating performance. The combination of the powerful V8 engine and the quick-shifting MCT transmission results in a 0-60 mph time of just 3.6 seconds. The 4MATIC+ all-wheel-drive system provides excellent traction, allowing for confident acceleration in various conditions. While the automatic transmission prioritizes performance, it also offers a comfortable driving experience in everyday situations. Compared to lower-powered GLC Coupe variants, such as the GLC 300, the 63 S offers a significantly more aggressive throttle response and a much higher level of overall performance. The suspension is tuned for sporty handling, providing minimal body roll and precise steering. However, this comes at the expense of some ride comfort compared to the standard GLC Coupe.
Equipment & Trim Levels
The AMG GLC 63 S came standard with a comprehensive list of features, including AMG-specific styling elements, such as a unique front grille, aggressive body kit, and quad exhaust outlets. The interior featured sport seats upholstered in Nappa leather, AMG steering wheel, and aluminum paddle shifters. Standard technology included a large infotainment display, navigation system, and a premium sound system. Optional extras included carbon fiber trim, a head-up display, and advanced driver-assistance systems like adaptive cruise control and lane-keeping assist. The interior was focused on a sporty luxury aesthetic, with high-quality materials and meticulous attention to detail.
Chassis & Braking
The AMG GLC 63 S features a performance-tuned chassis with AMG Ride Control suspension, which utilizes adaptive dampers to adjust to varying road conditions. The suspension lowers the vehicle’s ride height for improved handling and stability. The braking system consists of large, ventilated discs with AMG-branded calipers, providing exceptional stopping power. The front brakes measure 390mm in diameter, while the rear brakes measure 360mm. The vehicle also incorporates ABS, electronic stability control, and traction control systems to enhance safety and control.
Market Reception & Comparison
The AMG GLC 63 S was generally well-received by automotive critics, who praised its powerful engine, responsive handling, and luxurious interior. However, some reviewers noted that the ride could be firm on rough roads. Compared to competitors like the Porsche Macan Turbo, the GLC 63 S offered a similar level of performance but with a more spacious interior and a lower price point. Fuel economy was a common criticism, with the combined fuel consumption of 10.7 l/100 km being relatively high for a vehicle in this class. Reliability reports have been generally positive, although the complexity of the engine and transmission could potentially lead to higher maintenance costs over the long term.
Legacy
The AMG GLC 63 S (C253) remains a desirable vehicle in the used car market. Its combination of performance, luxury, and practicality continues to appeal to buyers seeking a high-end SUV. The M177 engine, while complex, has proven to be relatively durable when properly maintained. Regular servicing and adherence to Mercedes-Benz’s recommended maintenance schedule are crucial for ensuring the long-term reliability of this powertrain. The vehicle’s advanced technology and sporty driving dynamics have cemented its place as a standout performer in the compact luxury SUV segment.
