2015-2017 Mercedes-Benz S-class Cabriolet (A217) AMG S 63 V8 (585 Hp) 4MATIC MCT

The Mercedes-Benz S-Class Cabriolet (A217) AMG S 63 4MATIC MCT, produced from September 2015 to 2017, represents the pinnacle of open-top luxury and performance within the A217 S-Class generation. Positioned as the flagship variant of the Cabriolet range, it combined the opulent comfort expected of an S-Class with the formidable power of Mercedes-AMG’s 5.5-liter V8 engine. This model catered to buyers seeking an uncompromising grand touring experience, blending exhilarating acceleration with sophisticated refinement. It was a relatively short-lived production run, superseded by updated models in subsequent years, making it a desirable vehicle for collectors and enthusiasts.

Technical Specifications

Powertrain & Engine Architecture

At the heart of the AMG S 63 Cabriolet lies the M157.985 5.5-liter V8 engine. This powerplant, a hallmark of Mercedes-AMG engineering, utilizes direct fuel injection and twin turbochargers to deliver a staggering 585 horsepower and 663.8 lb-ft of torque. The engine’s architecture features a hot-inner-V configuration, positioning the turbochargers within the V of the engine block, reducing exhaust path length and improving responsiveness. The engine is longitudinally mounted at the front of the vehicle. The MCT (Multi Clutch Technology) 7-speed automatic transmission, developed by AMG, is a key component of the powertrain. Unlike a traditional torque converter automatic, the MCT utilizes a wet multi-plate clutch pack for quicker and more direct gear changes. This transmission is tuned for both performance and comfort, offering smooth shifts during normal driving and rapid, precise shifts in Sport+ mode. The 4MATIC all-wheel-drive system distributes power to all four wheels, enhancing traction and stability, particularly in adverse weather conditions.

Driving Characteristics

The AMG S 63 Cabriolet delivers a driving experience that is both exhilarating and refined. The combination of the powerful V8 engine and the responsive MCT transmission results in blistering acceleration – 0 to 60 mph in just 3.7 seconds. The 4MATIC system ensures confident handling, even when pushing the car to its limits. The suspension, featuring AMG’s adaptive damping system, provides a comfortable ride in Comfort mode while firming up in Sport and Sport+ modes for improved body control. The steering is precise and well-weighted, offering good feedback to the driver. Compared to the standard S-Class Cabriolet models with smaller engines, the S 63 offers a significantly more potent and engaging driving experience. While the lower-powered variants prioritize comfort and fuel efficiency, the S 63 is unapologetically focused on performance.

Equipment & Trim Levels

The AMG S 63 Cabriolet came standard with a comprehensive array of luxury and technology features. Interior appointments included premium leather upholstery, heated and ventilated front seats with massage functions, and a high-end Burmester surround sound system. Standard equipment also included Mercedes-Benz’s COMAND infotainment system with navigation, a head-up display, and a suite of advanced driver-assistance systems, such as adaptive cruise control, lane-keeping assist, and automatic emergency braking. Optional extras included carbon fiber trim, upgraded leather options, and a rear-seat entertainment system. The exterior featured AMG-specific styling cues, including a unique front fascia, side skirts, and rear diffuser, as well as large alloy wheels and high-performance brakes.

Chassis & Braking

The chassis of the S 63 Cabriolet is based on the A217 platform, but with significant AMG-specific enhancements. The suspension utilizes an independent multi-link setup at both the front and rear, optimized for performance and comfort. AMG-tuned dampers and air suspension contribute to a balanced ride. Braking duties are handled by large, ventilated discs at all four corners, providing ample stopping power. The braking system is further enhanced by AMG’s high-performance brake pads and calipers. The car features a speed-sensitive steering rack and pinion system for precise control at all speeds.

Market Reception & Comparison

The AMG S 63 Cabriolet was widely praised by automotive critics for its exceptional performance, luxurious interior, and advanced technology. However, its high price tag and relatively low fuel economy were noted drawbacks. Compared to other high-performance convertibles of the time, such as the Porsche 911 Turbo Cabriolet, the S 63 offered a more luxurious and comfortable experience, but with slightly less focused handling. The S 63 also stood out from other S-Class Cabriolet variants, such as the S 550, by offering a significantly more powerful engine and a more aggressive driving experience. Reliability reports suggest that the M157 engine is generally robust, but maintenance costs can be high due to the complexity of the engine and the specialized parts required.

Legacy

The Mercedes-Benz S-Class Cabriolet (A217) AMG S 63 4MATIC MCT remains a highly sought-after vehicle in the used car market. Its combination of luxury, performance, and exclusivity continues to appeal to discerning buyers. While maintenance costs can be substantial, the car’s robust construction and relatively straightforward mechanical design (for a modern luxury vehicle) contribute to its long-term reliability. The M157 engine, despite its complexity, has proven to be a durable powerplant when properly maintained. The A217 S 63 Cabriolet represents a high point in Mercedes-AMG’s history, showcasing the brand’s commitment to delivering uncompromising performance and luxury in an open-top format.
