2012-2014 Mercedes-Benz CLS Shooting Brake (X218) AMG CLS 63 V8 (557 Hp) 4MATIC SPEEDSHIFT

Technical Specifications

The X218 CLS Shooting Brake, launched in 2012, was Mercedes-Benz’s attempt to carve out a niche in the market for a stylish, performance-oriented wagon. Building upon the success of the CLS four-door coupe, the Shooting Brake added a practical cargo area without sacrificing the vehicle’s sleek profile. The AMG CLS 63 variant, with its potent 5.5-liter twin-turbo V8, represented the pinnacle of performance for this body style. It was a direct competitor to vehicles like the Porsche Panamera Sport Turismo and high-performance versions of the Audi A6 Avant, though it occupied a slightly more luxurious and visually striking position in the market.

Powertrain & Engine Architecture

At the heart of the AMG CLS 63 Shooting Brake lies the M157.981 5.5-liter V8 engine. This engine, a significant departure from the naturally aspirated AMG V8s of the past, utilizes direct injection and twin turbochargers to deliver substantial power and torque. The engine features a cylinder deactivation system (“cylinder management”) which shuts down cylinders 2, 3, 5, and 8 during light load conditions to improve fuel economy. The engine’s architecture includes a forged crankshaft, piston rings, and connecting rods, designed to withstand the stresses of high performance. The 7G-TRONIC SPEEDSHIFT transmission, a seven-speed automatic, is specifically tuned for AMG models, offering quick and precise gear changes. It features multiple driving modes, including a manual mode allowing the driver to control gear selection via steering wheel-mounted paddle shifters. The 4MATIC all-wheel-drive system distributes power between the front and rear axles, enhancing traction and stability, particularly in adverse weather conditions.

Driving Characteristics

The AMG CLS 63 Shooting Brake delivers a driving experience that blends effortless power with a surprisingly comfortable ride. The twin-turbo V8 provides immense torque from as low as 1750 rpm, resulting in strong acceleration in any gear. The 0-60 mph sprint takes just 3.6 seconds, making it a genuinely quick vehicle. The SPEEDSHIFT transmission is responsive and smooth, although some drivers may find it slightly less engaging than a dual-clutch transmission. The 4MATIC system provides excellent grip, inspiring confidence in corners. While the CLS 63 is a large vehicle, the well-tuned suspension minimizes body roll and provides a composed feel. Compared to the standard CLS models, the AMG variant offers a significantly more aggressive driving experience, with sharper throttle response and a more direct steering feel. Compared to the CLS 550, the 63 offers a substantial performance upgrade, while the diesel-powered CLS 350 CDI prioritizes fuel efficiency over outright speed.

Equipment & Trim Levels

The AMG CLS 63 Shooting Brake 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 technology included a COMAND infotainment system with navigation, a premium sound system, and a suite of driver-assistance features such as adaptive cruise control, lane-keeping assist, and blind-spot monitoring. Optional extras included a panoramic sunroof, a rear-seat entertainment system, and upgraded interior trim materials. The exterior featured AMG-specific body styling, including a unique front fascia, side skirts, and rear diffuser. Larger wheels and performance tires were also standard.

Chassis & Braking

The CLS 63 Shooting Brake utilizes a sophisticated chassis design to deliver a balance of comfort and handling. The front suspension features a McPherson strut design with coil springs and an anti-roll bar, while the rear suspension employs a multi-link setup. The AMG Adaptive Sports Suspension allows the driver to adjust the damping characteristics to suit their preferences. The braking system consists of ventilated discs at all four corners, with large calipers providing ample stopping power. The AMG Performance braking system, an optional upgrade, featured even larger rotors and calipers for enhanced fade resistance during track use.

Market Reception & Comparison

The AMG CLS 63 Shooting Brake was generally well-received by automotive critics, who praised its performance, luxurious interior, and unique styling. However, some reviewers noted its high price tag and relatively limited practicality compared to more traditional wagons. Fuel economy, while respectable for a vehicle of its performance, was not a strong point. Compared to the CLS 550, the 63 offered a significant performance advantage but at a higher cost. The diesel-powered CLS 350 CDI provided better fuel economy but lacked the AMG’s exhilarating performance. The Porsche Panamera Sport Turismo was often cited as a direct competitor, offering similar performance and practicality, but with a different aesthetic.

Legacy

The AMG CLS 63 Shooting Brake remains a desirable vehicle in the used car market, appealing to enthusiasts who appreciate its combination of performance, luxury, and exclusivity. The M157 engine, while complex, has proven to be relatively reliable when properly maintained. Common maintenance items include regular oil changes, spark plug replacements, and inspection of the turbochargers. The 7G-TRONIC transmission is generally durable, but may require servicing at higher mileages. The CLS 63 Shooting Brake represents a unique chapter in Mercedes-Benz’s history, showcasing the brand’s willingness to experiment with unconventional body styles and high-performance powertrains.
