The Mercedes-Benz W111 Coupe 280 SE 3.5 V8, produced between November 1969 and July 1971, represents the pinnacle of the W111 series, often considered one of the most elegant and technologically advanced grand tourers of its era. As a two-door coupe variant of the W111 “Fintail” sedan, it catered to buyers seeking a luxurious and powerful vehicle with distinctive styling. The 280 SE 3.5 V8 was the final iteration of the W111 coupe, boasting a significantly upgraded engine compared to its predecessors and cementing its place as a collector’s item today. It was primarily sold in Europe and other international markets, embodying the German engineering prowess and sophisticated design that Mercedes-Benz was becoming renowned for.
The Mercedes-Benz W111 Coupe: A Legacy of Engineering
The W111 series, introduced in 1959, was a significant departure for Mercedes-Benz, featuring unibody construction – a first for the brand – and a focus on passenger safety. The coupe version, launched in 1961, offered a more sporting and exclusive alternative to the sedan. The 280 SE 3.5 V8 represents the culmination of this design, incorporating the latest advancements in engine technology and refinement. It was positioned as a premium vehicle, competing with grand tourers from brands like BMW and Jaguar, offering a blend of performance, comfort, and prestige.
Engine & Performance
The heart of the 280 SE 3.5 V8 is its 3.5-liter (3499 cm3 or 213.52 cu. in.) M 116 E 35 V8 engine. This engine, producing 200 horsepower at 5800 rpm and 286 Nm (210.94 lb.-ft.) of torque at 4000 rpm, was a substantial upgrade over the previous inline-six engines offered in the W111 coupe. The engine featured multi-port manifold fuel injection, contributing to its smooth power delivery and relatively good fuel economy for the time – 13 liters per 100 kilometers (18.1 US mpg). Power is sent to the rear wheels via a 4-speed manual transmission. Performance figures include a 0-60 mph (0-96 km/h) time of approximately 8.6 seconds and a top speed of 210 km/h (130.49 mph). The engine’s power-to-weight ratio is 7.9 kg/Hp, and the torque-to-weight ratio is 5.5 kg/Nm.
Design & Features
The W111 Coupe 280 SE 3.5 V8 retains the distinctive “fintail” styling of the W111 series, characterized by prominent fins extending rearward from the rear wheel arches. However, the coupe benefits from a lower roofline and more streamlined profile, enhancing its sporting appearance. The interior is lavishly appointed with high-quality materials, including wood trim, leather upholstery, and chrome accents. The vehicle comfortably seats five passengers, although rear seat space is somewhat limited due to the coupe body style. Safety features, while not as comprehensive as modern standards, included disc brakes on all four wheels – a significant advancement for the era – and a robust unibody structure designed to protect occupants in the event of a collision. Hydraulic power steering was standard, making the relatively large vehicle easier to maneuver. The car’s curb weight is 1570 kg (3461.26 lbs) and has a maximum load capacity of 470 kg (1036.17 lbs).
