🔍 Model Background

The Mercedes 400 SEL (1993) was a luxury long-wheelbase sedan from the early W140 S-Class generation, offering a sophisticated blend of V8 performance, advanced technology, and limousine-like comfort. Positioned between the inline-six 300 SE/SEL and the V12-powered 600 SEL, the 400 SEL delivered smooth power and premium refinement in a more balanced package.

Power came from a 4.2-liter M119 DOHC V8 engine, producing approximately 275 horsepower and 295 lb-ft of torque. Paired with a 4-speed automatic transmission, the 400 SEL offered strong, effortless acceleration and serene highway cruising, consistent with the W140's grand touring intent.

Built on the extended-wheelbase version of the W140 chassis, the 400 SEL provided generous rear-seat legroom, excellent ride comfort, and outstanding high-speed stability. Features such as double-pane acoustic glass, soft-close doors, and optional adaptive damping suspension contributed to its quiet and composed ride.

Inside, the cabin reflected Mercedes-Benz’s highest luxury standards of the era, including leather upholstery, burled walnut wood trim, dual-zone climate control, memory seats, rear passenger amenities, and premium audio. The 1993 400 SEL remains a sought-after classic today, valued for its refined V8 power, executive presence, and the overbuilt quality of the W140 series.
