The original 1963 Corvette Grand Sports need no introduction to enthusiasts.
But while those five special racing Corvettes dreamed up so long ago by Zora Arkus-Duntov were great cars, the truth is a lot of advancements have been made over the past 58 years.
So what if a ’63 Grand Sport could be brought into the 21st century to take advantage of all that progress?
Well, it has been by a 25-year-old company named Superformance, which is licensed by GM to build replica Grand Sports built off the original GM tooling but with all the modern conveniences.
YouTube’s “AutotopiaLA” recently spotlighted one of their latest creations, and the video offers some insight into just how special these cars are.
This particular one boasts of a Mercury Racing SB4 engine that despite being naturally aspirated manages to crank out a whopping 750 horsepower and revs up to 8,000 RPM. It’s hooked to a Tremec T56 six-speed transmission.
But that’s just the beginning of the story about this car.
Let’s move to the interior, where it’s graced by leather upholstery, carpet, Vintage Air conditioning, a tilt steering wheel, power windows, AutoMeter gauges, and other civilized amenities not present in those original Grand Sports that makes it into a very livable air.
The replicas even have a trunk where the race car had an access panel to the rear suspension and differential to service those parts during a race.
All in all, we feel sure Zora would be pleased with these upgrades to his Grand Sports, which were nixed by GM before the planned 125 could be built. Fortunately, he was able to save all five actually built from the crusher and now they are some of the most prized Corvettes in existence.
