2013-2016 Mercedes-Benz S-class Long (V222) S 500 V8 (455 Hp) 7G-TRONIC PLUS

The Mercedes-Benz S-Class Long (V222) S 500 V8, produced from May 2013 to February 2016, represents a pinnacle of luxury and performance within the flagship S-Class range. This extended-wheelbase variant, designated V222, was primarily aimed at markets where rear passenger space was highly valued, such as China and other parts of Asia, though it was also available in North America and Europe. Positioned as a high-end trim, the S 500 V8 offered a significant step up in power and refinement compared to the base S 350 and S 400 models, while remaining below the ultra-luxury offerings like the S 600. It utilized Mercedes-Benz’s advanced technology and engineering to deliver a supremely comfortable and capable driving experience.

Powertrain & Engine Architecture

The S 500 V8 is powered by Mercedes-Benz’s M278.929 4.7-liter V8 engine. This engine is a significant departure from earlier Mercedes V8s, featuring direct injection, twin turbochargers, and a sophisticated valvetrain. The M278 utilizes a spray-guided direct injection system, injecting fuel directly into the combustion chamber at pressures up to 200 bar (2,900 psi) for improved efficiency and reduced emissions. The engine employs a dual overhead camshaft (DOHC) design with four valves per cylinder, optimizing airflow for increased power output. The twin-turbocharger setup, with one turbocharger per cylinder bank, provides a broad torque curve and minimizes turbo lag. The 7G-TRONIC PLUS seven-speed automatic transmission, a mainstay of Mercedes-Benz vehicles, is paired with the engine. This transmission is known for its smooth shifting and efficiency, offering both manual and automatic shift modes. The transmission’s gear ratios are tuned to balance performance and fuel economy, with a relatively tall seventh gear for highway cruising.

Driving Characteristics

The S 500 V8 delivers a refined and powerful driving experience. The 455 horsepower and 516 lb-ft of torque provide effortless acceleration, with a 0-60 mph time of around 4.6 seconds. The 7G-TRONIC PLUS transmission contributes to this performance with quick and seamless gear changes. Compared to the S 400, which typically featured a smaller V6 engine, the S 500 V8 offered a substantial increase in power and torque, resulting in noticeably quicker acceleration and more confident passing maneuvers. While not as overtly sporty as some of its rivals, the S 500 V8 prioritizes comfort and refinement. The air suspension system effectively isolates passengers from road imperfections, providing a smooth and luxurious ride. The steering is precise and well-weighted, offering a good balance between feedback and ease of use.

Equipment & Trim Levels

The S 500 V8 came standard with a comprehensive array of luxury features. Interior appointments typically included premium leather upholstery, wood trim, and brushed aluminum accents. Standard equipment included heated and ventilated front seats with massage functions, a panoramic sunroof, a premium sound system, and a sophisticated infotainment system with navigation. The long-wheelbase configuration provided significantly more rear legroom than the standard S-Class, enhancing comfort for rear passengers. Optional extras included rear-seat entertainment systems, upgraded leather packages, and various driver-assistance features such as adaptive cruise control, lane-keeping assist, and a 360-degree camera system.

Chassis & Braking

The S-Class Long (V222) utilized an independent multi-link suspension system at both the front and rear axles. The air suspension system, standard on the S 500 V8, provided adjustable ride height and damping, allowing drivers to tailor the suspension to their preferences. Stabilizer bars were fitted to both axles to reduce body roll during cornering. The braking system consisted of ventilated discs at all four corners, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) were standard safety features. The S 500 V8’s chassis was engineered to provide a comfortable and controlled ride, prioritizing stability and refinement over outright sportiness.

Market Reception & Comparison

The S 500 V8 was generally well-received by automotive critics. It was praised for its powerful engine, luxurious interior, and advanced technology. Critics noted that the S 500 V8 offered a compelling combination of performance and comfort, making it a strong contender in the luxury sedan segment. Compared to the S 400, the S 500 V8 offered a significant performance advantage, but at a higher price point. The S 600, with its even more powerful V12 engine, provided even greater performance but came with a substantially higher cost. Fuel economy was respectable for a vehicle of its size and performance, with combined fuel consumption figures ranging from 27.4 to 25.8 US mpg.

Legacy

The M278 engine family, including the one found in the S 500 V8, has proven to be relatively reliable, although preventative maintenance is crucial. Common issues include occasional turbocharger failures and oil leaks. The 7G-TRONIC PLUS transmission is also generally reliable, but requires regular fluid changes to ensure smooth operation. Today, the S 500 V8 (V222) represents a desirable entry point into the modern S-Class ownership experience. Its combination of luxury, performance, and technology continues to appeal to buyers seeking a high-end sedan. Well-maintained examples command a premium in the used car market, reflecting the enduring appeal of the S-Class nameplate.
