Powertrain & Engine Architecture
At the heart of the CLS 63 S Shooting Brake lies the M157.981 5.5-liter V8 engine. This engine utilizes direct fuel injection and twin turbochargers to produce its impressive output. The turbochargers are positioned within the ‘V’ of the engine, reducing exhaust gas routing and improving responsiveness. The engine also features cylinder deactivation, shutting off cylinders under light load to improve fuel economy. The 7-speed MCT (Multi Clutch Technology) automatic transmission is a key component of the powertrain. Unlike a traditional torque converter automatic, the MCT uses a wet clutch pack to deliver quicker and more direct shifts. This transmission is tuned for performance, offering paddle shifters for manual control and various driving modes to adjust shift points and responsiveness. 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 CLS 63 S Shooting Brake delivers a truly exhilarating driving experience. The combination of the powerful V8 engine, the quick-shifting MCT transmission, and the all-wheel-drive system results in blistering acceleration – 0 to 60 mph in around 3.5 seconds. The engine provides a broad torque curve, offering strong pull throughout the rev range. While the automatic transmission is generally smooth, it can be surprisingly aggressive in Sport+ mode, delivering rapid gear changes and a more engaging driving experience. Compared to the standard CLS models or even the CLS 63 with a slightly lower output, the ‘S’ variant offers a noticeably more potent and dynamic driving experience. The suspension is tuned for performance, providing a firm but controlled ride. However, it’s not overly harsh, maintaining a reasonable level of comfort for everyday driving.
Equipment & Trim Levels
The CLS 63 S Shooting Brake came standard with a comprehensive list of luxury and performance features. Interior appointments included premium leather upholstery, heated and ventilated front seats with massage functions, and a high-end Burmester surround sound system. Standard technology included a large infotainment screen with navigation, a rearview camera, and a suite of driver-assistance systems such as blind-spot monitoring and lane-keeping assist. Optional extras included carbon fiber trim, upgraded leather options, and a head-up display. The interior design was generally consistent with other high-end Mercedes-Benz models, emphasizing luxury and sophistication.
Chassis & Braking
The CLS 63 S Shooting Brake features a sophisticated chassis designed to handle the engine’s power. The front suspension utilizes a McPherson strut design with coil springs and an anti-roll bar, while the rear suspension employs a multi-link setup. This configuration provides a good balance of ride comfort and handling precision. The braking system consists of ventilated discs on all four wheels, providing ample stopping power. Large calipers and high-performance brake pads were standard equipment. The steering is a rack-and-pinion system with electric power assistance, offering precise and responsive steering feel.
Market Reception & Comparison
The CLS 63 S Shooting Brake was generally well-received by automotive critics. It was praised for its powerful engine, dynamic handling, and luxurious interior. However, some critics noted its high price tag and relatively limited practicality compared to more traditional station wagons. Compared to other performance wagons, such as the Audi RS6 Avant or the BMW M5 Touring (not officially sold in the US during this period), the CLS 63 S offered a unique blend of style and performance. Fuel economy, while respectable for a vehicle of this type, was not a strong point, with combined fuel consumption around 22.2 US mpg. Reliability was generally good, although the complex engine and transmission systems could potentially require expensive repairs.
Legacy
The Mercedes-Benz CLS 63 S Shooting Brake (X218) remains a desirable vehicle in the used car market. Its combination of performance, luxury, and distinctive styling has made it a favorite among enthusiasts. The M157 V8 engine, while complex, has proven to be relatively durable when properly maintained. However, potential buyers should be aware of the potential for expensive repairs, particularly related to the turbochargers and the MCT transmission. The CLS 63 S Shooting Brake represents a unique chapter in Mercedes-Benz history, offering a compelling alternative to traditional performance cars.
