The XP-755 concept car, also known as the Mako Shark, was designed under the direction of GM in 1961, as a concept for future Corvette production cars. In keeping with the name, the streamlining, pointed snout, and other detailing was partly inspired by the sleek, fast-moving shortfin mako shark. The '61 Corvette tail was given two additional tail lights (six total) for the concept car. The concept was inspired by Bill Mitchell's 1959 Sting Ray XP87 which also inspired the 1963 corvette Sting ray.
