16. The First Car To Break The 400 Horsepower Mark
The late-1950s wasn’t a good era for sports car production. The combination of a recession alongside some fairly ugly designs resulted in a noticeable drop in purchases of vehicles from the Big Three. However, not all was lost from that era. In 1958, while the outside wasn’t looking great, the performance was just fine. The 1958 Mercury Marauder became the first production muscle car to break the 400hp mark. Three two-barrel carburetors sitting atop the 360-horsepower engine gave it the extra push to reach the 400hp mark.
