2002-2005 Mercedes-Benz S-class (W220 facelift ) S 350 V6 (245 Hp) 4MATIC 5G-TRONIC

The Mercedes-Benz S 350 4MATIC, produced from 2002 to 2005, was a significant variant within the W220 S-Class facelift range. Representing a middle-ground offering in the lineup, it slotted between the entry-level S 320 and the more powerful S 430 and S 500 models. This iteration of the S-Class, internally designated as the W220, benefited from a substantial refresh in 2002, addressing earlier criticisms and enhancing the overall refinement and technological sophistication of the flagship sedan. The S 350 4MATIC aimed to provide a balance of performance, luxury, and all-weather capability, appealing to buyers seeking a prestigious vehicle without the top-tier price tag.

At the heart of the S 350 4MATIC lies the M 112 E 37 engine, a 3.7-liter naturally aspirated V6. This engine, bearing the internal code 112.975, produced 245 horsepower at 5700 rpm and 350 Nm (258.15 lb-ft) of torque at 3000 rpm. The engine utilized multi-port fuel injection and a 10:1 compression ratio. The V6 configuration provided a smooth and refined power delivery, characteristic of Mercedes-Benz engines of the era. Power was transmitted to all four wheels via a 5G-TRONIC five-speed automatic transmission. This transmission was known for its smooth shifting and adaptive learning capabilities, adjusting shift points based on driving style. The 4MATIC all-wheel-drive system employed a sophisticated system to distribute torque between the front and rear axles, enhancing traction and stability, particularly in adverse weather conditions.

The S 350 4MATIC offered a comfortable and composed driving experience. While not as overtly sporty as the V8-powered models, the V6 provided adequate acceleration, achieving 0-60 mph in approximately 7.5 seconds and a top speed of 150.37 mph. The automatic transmission contributed to a relaxed cruising experience, with well-chosen gear ratios for both highway and city driving. The 4MATIC system instilled confidence in slippery conditions, providing enhanced grip and control. Compared to the rear-wheel-drive S 350, the 4MATIC version offered noticeably improved traction, albeit with a slight increase in weight and fuel consumption.

Standard equipment on the S 350 4MATIC was comprehensive, reflecting its position as a luxury vehicle. This included leather upholstery, power-adjustable front seats with memory function, automatic climate control, a premium audio system, and a sunroof. The interior design was characterized by high-quality materials and meticulous craftsmanship. Optional extras included features such as a navigation system, rear seat entertainment, massaging seats, and various wood trim options. The S 350 4MATIC typically featured a more restrained interior aesthetic compared to the higher-end models, focusing on understated elegance rather than overt opulence.

The S 350 4MATIC utilized a fully independent suspension system, featuring coil springs, shock absorbers, and stabilizer bars. The front suspension employed a multi-link design, while the rear utilized a semi-trailing arm setup. This configuration provided a comfortable ride quality while maintaining good handling characteristics. Braking duties were handled by disc brakes on all four wheels, supplemented by ABS (Anti-lock Braking System) and electronic brake-force distribution. The suspension was tuned to prioritize comfort, resulting in a smooth and refined ride, although it wasn’t as firm or sporty as some competitors.

Contemporary reviews of the S 350 4MATIC generally praised its comfortable ride, refined engine, and all-weather capability. Critics noted that while the V6 engine didn’t offer the same exhilarating performance as the V8s, it provided sufficient power for most driving situations. Fuel economy was considered reasonable for a vehicle of its size and class, although it wasn’t a standout feature. Reliability was generally good, although some owners reported issues with the electronic systems and air suspension components, common to the W220 generation. Compared to the S 430, the S 350 4MATIC offered a more affordable entry point into the S-Class range, while still providing a luxurious and well-equipped experience.

Today, the S 350 4MATIC (W220) represents an affordable entry point into the world of Mercedes-Benz luxury. While older examples may require maintenance to address age-related issues, the M 112 engine is generally considered robust and reliable. The 5G-TRONIC transmission, when properly maintained, can provide years of smooth operation. The availability of parts is generally good, and the S 350 4MATIC remains a popular choice for buyers seeking a comfortable, well-equipped, and prestigious sedan at a reasonable price point. Its all-wheel-drive system continues to be a valuable asset in regions with inclement weather.
