Powertrain & Engine Architecture
The heart of the S 500 4MATIC is the M278.929 4.7-liter V8 engine. This engine is a sophisticated, direct-injection powerplant featuring twin turbochargers and an intercooler. The direct injection system, operating at pressures up to 200 bar, ensures precise fuel delivery for optimal combustion. The engine utilizes a double overhead camshaft (DOHC) valvetrain with four valves per cylinder, maximizing airflow and contributing to its high power output. The 7G-TRONIC PLUS automatic transmission, a seven-speed unit, was specifically tuned to complement the V8’s power delivery. This transmission offered smooth and responsive shifts, contributing to both performance and fuel efficiency. The 4MATIC all-wheel-drive system provides enhanced traction and stability, particularly in adverse weather conditions.
Driving Characteristics
The S 500 4MATIC delivered a refined and powerful driving experience. The 455 horsepower and 516 lb-ft of torque provided effortless acceleration, with a 0-60 mph time of around 4.6 seconds. The 7G-TRONIC PLUS transmission’s gear ratios were optimized for both performance and fuel economy, offering quick downshifts for overtaking and comfortable cruising at highway speeds. Compared to the S 400 Hybrid, the S 500 offered significantly more power and a more engaging driving experience. While not as overtly sporty as some competitors, the S 500 prioritized comfort and refinement without sacrificing performance. The air suspension system further enhanced ride quality, absorbing bumps and providing a smooth, isolated experience for passengers.
Equipment & Trim Levels
The S 500 4MATIC came standard with a comprehensive array of luxury features. Interior appointments included high-quality leather upholstery, wood trim, and brushed aluminum accents. Standard equipment typically included a premium sound system, a large infotainment screen with navigation, heated and ventilated front seats with massage functions, and a panoramic sunroof. Optional extras included rear-seat entertainment systems, upgraded leather packages, and advanced driver-assistance features such as adaptive cruise control, lane-keeping assist, and a 360-degree camera system. The extended wheelbase provided significantly more rear legroom, making it a particularly appealing choice for chauffeured transport.
Chassis & Braking
The S-Class Long utilized an independent multi-link suspension system at both the front and rear, enhanced by Mercedes-Benz’s AIRMATIC air suspension. This system automatically adjusted the suspension damping and ride height to optimize comfort and handling. The S 500 4MATIC was equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) and electronic stability control (ESC) were standard features, enhancing safety and control. The steering system was a speed-sensitive power steering rack and pinion, providing precise and responsive steering feel.
Market Reception & Comparison
The S 500 4MATIC was generally well-received by automotive critics, who praised its luxurious interior, powerful engine, and refined driving experience. It was often compared favorably to its rivals, such as the BMW 7 Series and the Audi A8. Fuel economy, while respectable for a vehicle of its size and performance, was a common point of discussion, with combined fuel consumption figures ranging from 24.5 to 25.8 US mpg. Reliability was generally good, although the complex technology could potentially lead to higher maintenance costs over the long term. Compared to the S 600, the S 500 offered a more accessible price point without sacrificing a significant amount of luxury or performance.
Legacy
The V222 S-Class, and specifically the S 500 4MATIC variant, established a new benchmark for luxury sedans. The M278 engine proved to be a robust and reliable powerplant, although preventative maintenance, particularly regarding the turbochargers and direct injection system, is crucial for long-term durability. On the used car market, these vehicles continue to command premium prices, reflecting their reputation for quality and refinement. The S 500 4MATIC remains a desirable choice for buyers seeking a luxurious and capable grand tourer.
