GM Design Team Shares Corvette Sting Ray Rendering From 1961

The GM Design team has shared a little-known sketch of a C2 Corvette Sting Ray concept completed by legendary designer Bill Porter back in 1961.

This sketch, which was shared to the GM Design Instagram page this week, was completed by Porter while the C2 Corvette Sting Ray production car was still in development. The GM Design team would have had a pretty good idea of what they wanted the C2 Corvette to look like at this point, as the Peter Brock and Larry Shinoda-designed 1959 Corvette Sting Ray Concept was already around for a couple of years. This would have given Porter a good jumping-off point to start his sketch, using recognizable C2 Corvette styling cues and expanding on the design with add-ons like a double bubble roof, a pointed hood and front and rear fender fins.

Porter’s sketch appears to be an early precursor to the XP-755 Concept Car, otherwise known as the Mako Shark. While the GM Design page does not reference the Mako Shark in its Instagram post, this sketch looks nearly identical to the Mako Shark show car, which was first presented to the public at the International Automobile Show in New York City in 1962. The design of the Mako Shark is attributed to Larry Shinoda, however, so it’s possible that Porter completed this sketch using a design that had already been mostly fleshed out by Shinoda.

Porter eventually went on to become the design studio chief for Pontiac, where he’d help pen iconic GM designs like the 1968 Pontiac GTO and 1970 Pontiac Firebird. Porter also lent his talents to designs for the Pontiac Le Mans, Catalina and Bonneville, among others. He retired from GM in 1996.

  • Two of my favourite designs ever. The creativity of these men and the teams should never be forgotten. Thanks for not letting that happen !!

  • The Mako Shark was even painted in shark-like colors. Was it Mitchell or Shinoda who got close enough to a shark to even know what colors a shark is...? I hope whichever one it was got a huge pay raise! Yikes!! LOL

    • The story that has gone around, is that Mitchell had caught a shark and had the head on his office wall. When the team failed several times to match the colors to Mitchell's satisfaction, they took the shark off the wall and painted it to match the car so that Mitchell was then satisfied.
