The 1990 Mercedes-Benz 500 SEC represents the pinnacle of engineering and luxury for the C126 series coupes in the second stage of production. This hardtop model, which stands out for its elegant lack of a B-pillar, is powered by the powerful 5.0-liter V8 (M117) engine. Thanks to the advanced Bosch KE-Jetronic injection system and the presence of the 3-way catalyst, this version produces 252 hp and an impressive torque of 390 Nm . With an aerodynamic silhouette ( Cd 0.35 ) and a cabin outfitted with the finest materials of the time, the 1990 500 SEC offers an unmatched combination between the performance of a Grand Tourer and the aristocratic style that made it the world’s elite favorite car by the end of its production.
