INTRODUCTION
The W212 generation Mercedes-Benz E-Class, produced from 2009 to 2016, represented a significant evolution in the brand’s mid-size executive sedan. The AMG E 63, introduced in April 2011, was the high-performance variant, replacing the previous E 63 powered by a naturally aspirated 6.2-liter V8. The switch to a 5.5-liter twin-turbocharged V8 (M157 engine) marked a substantial increase in power and torque, while also incorporating fuel-saving technologies like cylinder deactivation. The AMG SPEEDSHIFT MCT 7-speed automatic transmission, a wet-clutch system, further enhanced performance and responsiveness. This model year bridged the gap between the older naturally aspirated AMG engines and the newer, more efficient turbocharged units.
Powertrain & Engine Architecture
At the heart of the AMG E 63 lies the M157.981 5.5-liter V8 engine. This engine utilizes direct fuel injection and twin turbochargers, one for each cylinder bank, to produce 525 horsepower at 5250-5750 rpm and a robust 700 Nm (516 lb-ft) of torque available from 1750 to 5000 rpm. The engine features a compression ratio of 10:1 and a sophisticated valvetrain with four valves per cylinder. The cylinder deactivation system, known as AMG Cylinder Management, shuts down cylinders 2, 3, 5, and 8 during partial-load operation, improving fuel economy. The AMG SPEEDSHIFT MCT transmission is a key component, replacing a traditional torque converter with a wet multi-plate clutch. This design provides faster shift times and a more direct connection between the engine and the rear wheels. The transmission offers Comfort, Sport, Sport Plus, and Manual modes, allowing the driver to tailor the driving experience.
Driving Characteristics
The AMG E 63 delivers a thrilling driving experience characterized by immense power and precise handling. The twin-turbo V8 provides instant throttle response and relentless acceleration, propelling the car from 0 to 60 mph in approximately 4.1 seconds. The AMG SPEEDSHIFT MCT transmission executes shifts with remarkable speed and smoothness, particularly in Sport and Sport Plus modes. While the automatic transmission isn’t as engaging as a dual-clutch system in some scenarios, it offers a good balance of performance and comfort. The suspension, featuring coil springs and a multi-link setup, provides a firm yet controlled ride. The rear air suspension contributes to ride comfort and allows for adjustable ride height. Compared to the naturally aspirated E 63, the turbocharged version offers significantly more low-end torque, making it more effortless in everyday driving situations. It also boasts improved fuel economy, despite the substantial power increase.
Equipment & Trim Levels
The AMG E 63 came standard with a comprehensive list of features, befitting its flagship status. Interior appointments included premium leather upholstery, AMG sport seats with enhanced bolstering, and carbon fiber trim. Standard equipment also included a panoramic sunroof, a premium sound system, and a navigation system. Optional extras included a performance exhaust system, ceramic composite brakes, and a driver assistance package with features like adaptive cruise control and lane keeping assist. The exterior styling was enhanced with AMG-specific body kit, including a unique front fascia, side skirts, and rear diffuser. Larger wheels and tires further distinguished the E 63 from other E-Class models.
Chassis & Braking
The chassis of the AMG E 63 was specifically tuned to handle the increased power output. It featured a stiffer suspension setup compared to standard E-Class models, along with larger stabilizer bars. The braking system consisted of ventilated discs on all four wheels, with larger rotors and calipers compared to lesser trims. The AMG E 63 also included ABS (Anti-lock Braking System) and electronic stability control. The rear suspension incorporated air springs, providing adjustable ride height and improved comfort. The steering system was a hydraulic rack-and-pinion setup, offering precise and responsive steering feel.
Market Reception & Comparison
The AMG E 63 was widely praised by automotive critics for its exceptional performance, luxurious interior, and advanced technology. It was consistently ranked among the top performers in its segment, competing directly with the BMW M5 and Audi RS 6. Critics noted the significant improvement in fuel economy compared to the previous generation E 63, thanks to the turbocharged engine and cylinder deactivation system. However, some reviewers found the ride quality to be firm, even in Comfort mode. Compared to the naturally aspirated E 63, the turbocharged version offered more accessible power and torque, making it a more versatile vehicle for everyday driving. The AMG SPEEDSHIFT MCT transmission was also lauded for its quick and smooth shifts.
Legacy
The W212 AMG E 63 represents a pivotal moment in the evolution of Mercedes-AMG’s high-performance sedans. The introduction of the twin-turbocharged V8 engine and the AMG SPEEDSHIFT MCT transmission set a new standard for performance and efficiency. Today, the W212 E 63 remains a desirable vehicle in the used car market, appealing to enthusiasts seeking a blend of luxury, performance, and exclusivity. The M157 engine, while known for its complexity, has proven to be relatively reliable when properly maintained. Regular servicing and attention to potential issues, such as oil leaks and turbocharger wear, are crucial for ensuring the long-term health of this powerful engine. The W212 E 63 continues to be a benchmark for performance sedans, demonstrating Mercedes-AMG’s commitment to engineering excellence.
