The Mercedes-Benz S 500 V8 (306 hp) represents a significant iteration within the W220 generation of the S-Class, produced between 1998 and 2002. Positioned as a mid-to-upper range offering within the W220 lineup, it bridged the gap between the entry-level S 320 and the flagship S 600 models. The W220 S-Class, launched in 1998, was a technologically advanced vehicle for its time, introducing features like DISTRONIC adaptive cruise control and an upgraded Pre-Safe system. The S 500 V8 aimed to deliver a balance of performance, luxury, and refinement, appealing to buyers seeking a powerful yet comfortable grand touring experience.
Powertrain & Engine Architecture
At the heart of the S 500 V8 lies the M113 E 50 engine, a 4.966-liter (303.04 cubic inches) naturally aspirated V8. This engine, designated with the code 113.960, is a key component of the W220’s engineering. It features a cast iron block with aluminum cylinder heads, employing three valves per cylinder (two intake, one exhaust). The engine utilizes multi-port fuel injection, delivering fuel directly into the intake ports. The M113 engine family was known for its robust construction and relatively simple design, contributing to its longevity and ease of maintenance compared to some of its contemporaries. The engine’s 97 mm bore and 84 mm stroke contribute to its strong torque output. The 5G-TRONIC automatic transmission, a five-speed unit developed by Mercedes-Benz, is paired with the M113 engine. This transmission is electronically controlled and offers smooth, refined shifts. It was a significant upgrade over previous Mercedes-Benz automatic transmissions, providing quicker response times and improved fuel efficiency.
5G-TRONIC Transmission Details
The 5G-TRONIC transmission in the S 500 V8 is a torque converter automatic. It features a sophisticated electronic control unit (TCU) that manages shift points based on driver input, vehicle speed, and engine load. The gear ratios are designed to provide a balance between acceleration and fuel economy. First gear is relatively short for quick off-the-line acceleration, while higher gears are geared for comfortable highway cruising. The transmission also includes a manual shift mode, allowing drivers to select gears manually for greater control, although this was less commonly used by S-Class owners prioritizing comfort.
Driving Characteristics
The S 500 V8 delivers a distinctly different driving experience compared to the lower-powered S 320 or the ultra-luxury S 600. With 306 horsepower and 460 Nm (339.28 lb-ft) of torque, the S 500 V8 offers brisk acceleration. Independent tests of the period consistently showed a 0-60 mph time of around 6.2 to 6.5 seconds, making it a genuinely quick sedan for its era. The 5G-TRONIC transmission contributes to smooth and seamless acceleration, masking the lack of a more modern gear count. Compared to the S 320, the S 500 V8 feels significantly more responsive, particularly when overtaking or merging onto highways. However, it lacks the outright brute force of the S 600, which featured a V12 engine. The suspension, tuned for comfort, provides a smooth and isolated ride, absorbing bumps and imperfections in the road effectively. The steering is precise and well-weighted, offering a confident feel at highway speeds.
Equipment & Trim Levels
The S 500 V8 came standard with a comprehensive array of luxury features. Interior appointments typically included leather upholstery, wood trim, and power-adjustable seats with memory function. Standard equipment also included automatic climate control, a premium sound system, and a sunroof. The S 500 V8 often served as a platform for optional extras, allowing buyers to customize their vehicles. Popular options included rear seat entertainment systems, massaging seats, and upgraded leather packages. The dashboard layout was typical of the W220 S-Class, featuring a large central display screen and intuitive controls. Exterior styling was understated and elegant, reflecting the S-Class’s status as a flagship luxury sedan.
Chassis & Braking
The W220 S-Class, including the S 500 V8, utilized a fully independent suspension system. The front suspension employed wishbones, while the rear suspension featured a multi-link design. This setup provided a comfortable ride and excellent handling characteristics. The S 500 V8 was equipped with ventilated disc brakes on all four wheels, providing ample stopping power. Anti-lock braking system (ABS) was standard, enhancing safety and control during emergency braking situations. The steering system was a rack-and-pinion setup with hydraulic power assistance, offering precise and responsive steering feel. The S 500 V8 typically rode on 225/60 R16 tires, mounted on 7.5J x 16 inch alloy wheels.
Market Reception & Comparison
The S 500 V8 was generally well-received by automotive critics. It was praised for its powerful engine, smooth transmission, and luxurious interior. Reviewers noted that the S 500 V8 offered a compelling blend of performance and comfort, making it an ideal choice for long-distance driving. Fuel economy, however, was a common criticism. The 13.4 l/100 km (17.6 US mpg) combined fuel consumption was relatively high, even for a large luxury sedan. Compared to the S 320, the S 500 V8 offered significantly more performance, but at the cost of increased fuel consumption and a higher purchase price. Compared to the S 600, the S 500 V8 provided a similar level of luxury but lacked the V12’s ultimate power and prestige. Reliability was generally good, although some owners reported issues with the electronic systems, a common trait of the technologically advanced W220 S-Class.

Legacy
The M113 engine, found in the S 500 V8, has proven to be a durable and reliable powerplant when properly maintained. While the W220 S-Class as a whole has faced some criticism for its complex electronics, the M113 engine itself is generally regarded as a strong and long-lasting unit. Today, the S 500 V8 represents an affordable entry point into W220 S-Class ownership. Used examples are readily available, and prices are relatively low compared to the S 320 or S 600. However, potential buyers should be aware of the potential for age-related issues, particularly with the suspension components and electronic systems. Regular maintenance and careful inspection are essential to ensure the continued reliability of this classic Mercedes-Benz.
