🔍 Model Background

The Mercedes 380 SEC (1982–1983) was the earliest V8-powered coupe variant of the W126 S-Class, introducing a new era of elegant grand touring performance and luxury. As the first of the SEC models, it featured a sleek two-door pillarless design that set it apart from its sedan counterparts with a sportier and more exclusive character.

Powering the 380 SEC was a 3.8-liter M116 SOHC V8 engine, producing approximately 155–160 horsepower and 196 lb-ft of torque in U.S.-spec versions. Mated to a 4-speed automatic transmission, it delivered smooth, relaxed performance suited for long-distance cruising, though it was not the most powerful option in the SEC range.

The 380 SEC featured the advanced engineering of the W126 platform, including four-wheel independent suspension, optional ABS brakes, and improved aerodynamics. Its wide stance and long hood gave it a commanding presence, while the pillarless side windows offered a truly open and refined coupe experience.

Inside, the cabin exuded luxury with leather or MB-Tex upholstery, rich wood trim, power-adjustable seats, automatic climate control, and high-end audio options. The coupe also featured excellent insulation and ride comfort, making it ideal for both daily driving and cross-continental travel.

Today, the 380 SEC is admired for its timeless design, early-1980s charm, and the foundational role it played in the prestigious SEC lineup. Though later models offered more power, the 380 SEC stands out for its balance of style, grace, and Mercedes-Benz craftsmanship.
