The 1966 Mercedes-Benz 250 SE Coupe (Generation W111) served as a significant technological improvement, replacing the 220 SE model with a more powerful engine and advanced chassis. This vehicle is powered by the M129 engine, a 2496 cm3 Gasoline engine with 6 cylinders in line and the Bosch mechanical injection system, which produces 150 hp / 148 hp/ 110 kW at 5500 rpm and a 216 nm torque at 4200 rpm. Equipped with a 4-speed manual gearbox , this model reaches a top speed of 190 km/h and accelerates from 0-100 km/h in 11.8 seconds . With a length of 4880 mm and classic B-pillar design, the 250 SE Coupe combined added performance with the timeless elegance of the then S-Class series.
