The 1991 Mercedes-Benz 300 SEL for the European market with catalyst represents the most refined and environmentally friendly variant of the extended-chassis limousine (V126) before the end of production. This model is powered by the reliable 3.0-liter M103 in-line 6-cylinder engine, which produces 180 hp and stands out for the perfect balance between performance and maintenance costs. With a wheelbase of 3075 mm , it offers a royal space for rear passengers, while the improved aerodynamics of the second stage ( Cd 0.33 ) ensure a smooth and efficient ride. The Lambda 3-way catalyst and sensor proves the technological maturity of this series, making the 300 SEL one of the most prestigious and sustainable limousines of Mercedes-Benz’s golden age.
