Powertrain & Engine Architecture
The heart of the S 500 was the M119.980 4.9-liter (303.47 cu. in.) naturally aspirated V8 engine. This engine was a significant evolution of Mercedes-Benz’s V8 design, featuring all-aluminum construction, dual overhead camshafts (DOHC), and four valves per cylinder. The M119 engine was renowned for its smoothness and robust build quality. Fuel delivery was handled by a multi-port fuel injection system, carefully calibrated to deliver optimal performance and efficiency. The engine produced 320 horsepower at 5600 rpm and 470 Nm (346.65 lb-ft) of torque at 3900 rpm. Paired with the engine was the 5G-TRONIC automatic transmission, a five-speed unit that offered smooth and refined gear changes. This transmission was electronically controlled, adapting to driving conditions and driver input for optimal performance.
Driving Characteristics
The S 500 offered a distinctly grand touring experience. While not overtly sporty, the 320 hp V8 provided ample power for effortless cruising and confident overtaking. The 5G-TRONIC transmission was tuned for comfort, prioritizing smooth shifts over aggressive downshifts. Acceleration from 0 to 60 mph took approximately 6.9 seconds, and the car was electronically limited to a top speed of 250 km/h (155 mph). Compared to the S420, the S 500 offered a noticeable increase in performance, while the S320 provided a more fuel-efficient, albeit slower, alternative. The automatic transmission, while convenient, did result in a slight performance deficit compared to the available manual transmissions in other S-Class models.
Equipment & Trim Levels
The S 500 came standard with a comprehensive list of luxury features, befitting its flagship status. Leather upholstery was standard, along with wood trim, power-adjustable front seats with memory function, and a premium sound system. Climate control, power windows, and central locking were also included. Optional extras included a rear seat entertainment system, a sunroof, and upgraded leather options. The interior design emphasized elegance and sophistication, with a focus on high-quality materials and meticulous craftsmanship.
Chassis & Braking
The W140 S-Class featured a robust chassis with independent suspension all around. The front suspension utilized coil springs and a double wishbone setup, while the rear employed an independent multi-link suspension. Both ends were equipped with a transverse stabilizer bar to reduce body roll. Braking duties were handled by ventilated disc brakes on all four wheels, assisted by an Anti-lock Braking System (ABS). The S 500’s suspension was tuned for a comfortable ride, absorbing bumps and imperfections in the road with ease. The steering was a recirculating ball system with hydraulic power assistance, providing a smooth and precise driving experience.
Market Reception & Comparison
The S 500 was generally well-received by automotive critics, who praised its luxurious interior, smooth ride, and powerful engine. However, its fuel consumption was often criticized, averaging around 15.4 l/100 km (15.3 US mpg). Compared to the S420, the S 500 offered a significant performance upgrade, justifying its higher price tag for those seeking more power. The S320, while more economical, lacked the prestige and performance of the S 500. Reliability was generally good, although the complex electronics of the W140 generation could occasionally present issues.
Legacy
The W140 S 500 remains a highly sought-after classic car, appreciated for its build quality, luxurious features, and iconic design. The M119 engine is known for its durability and longevity, and well-maintained examples can still provide years of reliable service. However, maintenance costs can be high due to the car’s age and complexity. Today, the S 500 represents a bygone era of automotive excess and engineering excellence, a testament to Mercedes-Benz’s commitment to building the ultimate luxury sedan.
