The 6.3

The Mercedes-Benz W109 vehicles were the top-of-the-line sedan in the late 60’s and early 70’s. Mercedes had a hold on the luxury car market that no other manufacturer could touch – and that hold was the legendary 300SEL 6.3. Known simply as “The 6.3”, Daimler-Benz made 6526 vehicles with the 109 chassis and equipped them with the legendary 6.3L cast-iron m100 taken directly from the 600 series. There are many fanbases and fansites dedicated soley to the m100-powered vehicles, and rightfully so. The 300SEL 6.3 was the fastest production sedan made for decades, until Mercedes-Benz outdid themselves in the early 90’s with the 500E and 600SEL vehicles. The 6.3, by conservative estimates, made 250HP and had a top speed of 220KM/H (~137MPH). More realistic figures put the 6.3 in the 300+ HP range.
