INTRODUCTION
The S 600 V12, produced between 2014 and 2017, was the ultimate expression of the V222 S-Class. Built on the long-wheelbase platform (adding approximately 3 inches to the standard S-Class wheelbase), it prioritized rear passenger comfort without sacrificing driving dynamics. The V222 generation, launched in 2013, was a significant leap forward in automotive technology, introducing features like MAGIC RIDE suspension, advanced driver-assistance systems, and a redesigned interior. The S 600 V12 stood apart with its hand-built, twin-turbocharged 6.0-liter V12 engine, offering a unique blend of power, refinement, and exclusivity.
Powertrain & Engine Architecture
At the heart of the S 600 V12 lies the M277.980 engine, a 6.0-liter, 12-cylinder powerplant. This engine is notable for its use of biturbocharging, employing two turbochargers positioned within the V of the engine to minimize exhaust gas routing and improve responsiveness. The engine utilizes multi-port fuel injection and a single overhead camshaft (SOHC) valvetrain. The M277 engine family was known for its smooth operation and substantial torque output. Paired with the engine is the 7G-TRONIC PLUS seven-speed automatic transmission, a sophisticated unit designed for smooth and efficient gear changes. This transmission featured a torque converter lock-up clutch to improve fuel economy and a wide range of gear ratios to optimize performance and comfort. The transmission was tuned specifically for the high torque output of the V12 engine.
Driving Characteristics
The S 600 V12 delivered a driving experience characterized by effortless power and exceptional refinement. The 530 horsepower and 612 lb-ft of torque provided brisk acceleration – 0 to 60 mph in approximately 4.4 seconds – but the focus wasn’t on outright sportiness. Instead, the emphasis was on providing a smooth, quiet, and supremely comfortable ride. The 7G-TRONIC PLUS transmission contributed to this experience, seamlessly shifting gears and keeping the engine in its optimal power band. Compared to the S 63 AMG, which prioritized performance, the S 600 V12 offered a more relaxed and luxurious driving experience. The gear ratios were tuned for comfortable cruising and effortless overtaking, rather than aggressive acceleration. Even compared to the S 550, the V12 offered a noticeable increase in torque, resulting in a more authoritative feel.
Equipment & Trim Levels
The S 600 V12 came standard with a comprehensive array of luxury features. The interior was typically adorned with premium leather upholstery, often with extended leather packages covering nearly every surface. Wood trim, typically burled walnut or mahogany, was standard, and buyers could opt for other exotic wood veneers. Standard equipment included heated and ventilated front and rear seats with massage functions, a premium Burmester surround sound system, a rear-seat entertainment system with dual screens, and a panoramic sunroof. The S 600 V12 also included Mercedes-Benz’s advanced driver-assistance systems, such as DISTRONIC PLUS with Steering Assist, PRE-SAFE Brake System, and Active Lane Keeping Assist. Optional extras included a refrigerator compartment in the rear center console, individual rear seats with reclining functions, and a variety of customization options through Mercedes-Benz’s Designo program.
Chassis & Braking
The V222 S-Class featured an advanced chassis design incorporating an Airmatic air suspension system with Adaptive Damping System (ADS) PLUS. The S 600 V12, in particular, often included the optional MAGIC RIDE suspension, which used road surface scanning technology to proactively adjust the suspension for an exceptionally smooth ride. The suspension geometry was optimized for both comfort and handling. Braking duties were handled by ventilated disc brakes on all four wheels, providing ample stopping power. The S 600 V12 also featured ABS (Anti-lock Braking System), Electronic Stability Program (ESP), and Brake Assist. The long wheelbase and increased weight of the S 600 V12 necessitated a robust braking system to ensure confident stopping performance.
Market Reception & Comparison
The S 600 V12 was not a high-volume seller, catering to a niche market of discerning buyers. Critics praised its exceptional refinement, luxurious interior, and effortless power. However, its high price tag and relatively low fuel economy limited its appeal. Compared to the S 63 AMG, the S 600 V12 was seen as a more sophisticated and comfortable choice, while the AMG prioritized performance. Against the S 550, the V12 offered a significant step up in luxury and exclusivity, but at a substantial price premium. Fuel economy was a common criticism, with combined figures around 20-21 mpg being typical.
Legacy
The M277 V12 engine, while complex, proved to be a relatively reliable powerplant when properly maintained. The 7G-TRONIC PLUS transmission also demonstrated good long-term durability. Today, the V222 S 600 V12 represents a unique and desirable classic. Its combination of luxury, performance, and advanced technology makes it a sought-after vehicle among collectors and enthusiasts. Maintenance costs can be higher than those of other S-Class variants due to the complexity of the V12 engine and the abundance of high-end features. However, well-maintained examples continue to command premium prices in the used car market, solidifying its status as a flagship luxury sedan.
