MERCEDES BENZTyp 300 "Adenauer" (W189) 1957 - 1962

　　In 1957 Mercedes-Benz heavily upgraded Typ 300 limousine, and built its new flagship model on top of a platform known as W189.

　　Mercedes-Benz's flagship model had to be changed after six years on the market. Even though it sported a similar shape, the new vehicle was built on top of a new platform with a long wheelbase and additional amenities. Still, the drivetrain was carried over from the W186, but it kept the same "Adenauer" nickname, honoring the chancellor who put Germany back on the map after WWII.

　　With its flared wheel arches visually extended over the front doors, the Typ 300 D was a luxurious vehicle. At the front, the car kept a similar front fascia as the W186, with a tilted radiator grille and new round headlights. In addition, the automaker installed parking lights on the front fenders, located between the chromed bumper and the headlights' trims. From its profile, the 1957 model featured a faux-cabriolet shape with a retractable B-post. At the back, the car sported small taillights on the large quarter panels.

　　Inside, Mercedes-Benz created a luxurious cabin with wood trims on the dashboard and door cards. At the front, there was a benchseat for two, while in the back, the bench was fit for three, even though it was profiled for just two persons.

　　The three-pointed star brand made a significant upgrade for the inline-six powerplant installed in the car, with the addition of a Bosch fuel-injection system. Thanks to this, it managed to squeeze 160 European ponies (158 hp) from the three-liter engine. Power went to the rear axle via a three-speed automatic or a four-speed manual.
