The 1970 Mercedes-Benz 300 SEL 6.3 for the North American market was the car that set new standards for the performance of luxury sedans in the US, becoming a transcontinental road legend. This vehicle is powered by the massive M100 6.3 engine, a 6332 cm3 Bosch Mechanical Injection Gasoline unit, which produces 250 hp / 247 HP / 184 kW in 4000 rpm and a torque of 500 Nm in 2800 rpm. Equipped with 4-speed automatic transmission and pneumatic suspension, this model reaches a top speed of 220 km/h and accelerates from 0-60 mph in just 6.1 seconds . Although with a higher weight due to the specifications of the American market, this sedan remained one of the fastest cars in the world, combining the luxuries of the SEL series with the unrivalled power of the V8 engine.
