INTRODUCTION
The S 500 V8 Long, introduced in 1995 as part of the W140 facelift, was designed to offer a superior driving experience and increased comfort compared to its siblings. The facelift brought subtle but significant cosmetic changes, including revised headlights and bumpers, along with improvements to the interior and technology. The extended wheelbase version, the “Long,” added approximately 100mm (3.9 inches) to the overall length, dedicating the extra space to rear passenger comfort. This model competed directly with other luxury sedans like the BMW 7 Series and the Audi A8, aiming to solidify Mercedes-Benz’s position as a leader in the premium automotive segment.
Powertrain & Engine Architecture
At the heart of the S 500 V8 Long lies the M119.980 5.0-liter V8 engine. This engine, a naturally aspirated powerplant, produced 320 horsepower at 5600 rpm and 470 Nm (346.65 lb-ft) of torque at 3900 rpm. The M119 engine family was renowned for its smoothness and reliability. It featured a cast-iron block with aluminum cylinder heads, dual overhead camshafts (DOHC), and four valves per cylinder. Fuel delivery was handled by a multi-port fuel injection system. The engine’s robust construction and sophisticated engineering contributed to its longevity and relatively easy maintenance. Paired with the engine was the 5G-TRONIC automatic transmission, a five-speed unit known for its smooth shifts and adaptability. This transmission was electronically controlled, offering drivers a choice between comfort and sport modes.
Driving Characteristics
The S 500 V8 Long delivered a refined and powerful driving experience. While not overtly sporty, the 320 hp engine provided ample acceleration, achieving 0-60 mph in approximately 6.9 seconds. The 5G-TRONIC transmission was well-matched to the engine’s characteristics, providing smooth and seamless gear changes. The extended wheelbase contributed to a more comfortable ride, absorbing bumps and imperfections in the road with ease. Compared to the S 420, the S 500 offered noticeably more power and a more responsive feel. The S 320, with its smaller engine, provided better fuel economy but lacked the S 500’s effortless performance. 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 V8 Long came standard with a comprehensive array of luxury features. Leather upholstery was standard, along with power-adjustable front seats with memory function. Wood trim adorned the interior, enhancing the sense of opulence. Standard equipment also included automatic climate control, a premium sound system, and power windows and locks. Optional extras included a rear entertainment system, heated seats (front and rear), a sunroof, and upgraded leather options. The “Long” variant specifically focused on rear passenger comfort, often equipped with features like reclining rear seats and individual climate controls.
Chassis & Braking
The S 500 V8 Long utilized a sophisticated chassis design focused on ride comfort and handling stability. The front suspension featured coil springs and a double wishbone setup with a transverse stabilizer bar. The rear suspension employed an independent multi-link system, also with a transverse stabilizer bar and coil springs. Braking duties were handled by ventilated disc brakes on all four wheels, coupled with an Anti-lock Braking System (ABS) for enhanced safety. The steering system was a cone worm with recirculation balls, providing precise and responsive control. The weight distribution was carefully balanced to minimize body roll and maximize stability.
Market Reception & Comparison
The S 500 V8 Long was generally well-received by automotive critics. It was praised for its luxurious interior, powerful engine, and comfortable ride. However, its fuel economy was often criticized, reflecting the inherent limitations of a large-displacement V8 engine. Compared to the S 420, the S 500 offered a significant performance upgrade, justifying its higher price tag for buyers prioritizing power. The S 320, while more fuel-efficient, was seen as lacking the prestige and performance of the S 500. Reliability was generally good, although maintenance costs were higher due to the complexity of the engine and the abundance of luxury features.
Legacy
The Mercedes-Benz S 500 V8 Long (W140) remains a highly sought-after classic car today. Its robust construction and relatively simple mechanicals (compared to later S-Class generations) make it a relatively reliable and maintainable vehicle. Well-maintained examples command premium prices in the used car market. The M119 engine is considered one of Mercedes-Benz’s finest V8s, known for its durability and smooth operation. The W140 S-Class, and particularly the S 500 Long, represents a high point in traditional Mercedes-Benz luxury, offering a blend of performance, comfort, and engineering excellence that continues to appeal to enthusiasts and collectors.
