Few cars in Chevrolet history carry as much mystique as the Corvette Grand Sport, the lightweight racer Zora Arkus-Duntov developed in secret to take on Ferrari and Shelby at Le Mans before GM brass shut the program down and ordered the cars destroyed. Only five were ever built, which makes an authentic, factory-authorized continuation example like this one a genuinely special way to own a piece of that legend.
This Superformance Corvette Grand Sport, chassis CGS0031, is finished in blue with a white center stripe outlined in red and #2 roundels on the hood, doors, and rear deck. Built as a GM-licensed continuation of the original 1963 racers, it pairs faithful period styling with thoroughly modern running gear, and it is currently up for auction with bidding already underway.
Power comes from a supercharged 6.2-liter LS9 V8, the same engine that powered the C6 Corvette ZR1, here reported to make roughly 635 horsepower. It breathes through ceramic-coated headers and stainless side-exit pipes, runs a track-oriented dry-sump oiling system, and sends its output to the rear wheels through a Tremec T56 six-speed manual transmission.
The hand-laminated fiberglass body sits on a four-inch tubular steel chassis and wears all the signature Grand Sport cues, from the vented hood and front fenders to the headlamp covers, flared rear fenders, bullet mirrors, and an externally mounted rear differential cooler. Staggered 17-inch front and 18-inch rear American Racing wheels in a Shelby Cobra style wrap Nitto NT555 tires measuring 255/50 up front and 305/40 out back.
Underneath, the suspension uses tubular control arms with adjustable front coilovers and a C2-style three-link rear with a transverse leaf spring and Bilstein dampers, while Wilwood four-wheel disc brakes and power rack-and-pinion steering keep it manageable on the road. Inside, the cabin is trimmed in black leather with bucket seats, Vintage Air climate control, power windows and locks, a tilt steering column, and a center-mounted switch panel.
As a GM-licensed continuation rather than a production Corvette, the Superformance Grand Sport sits outside the standard price guides — but the comps that do exist speak for themselves. Classic.com records past sales of $145,900 and $165,000 for these hand-built recreations, putting this supercharged, LS9-powered example squarely in six-figure company among the most desirable Corvette tributes money can buy.
Showing roughly 2,000 miles, the car is offered by County Corvette in West Chester, Pennsylvania, and will include a clean Pennsylvania title listing it as a 1963 Chevrolet. For collectors who want the look and the history of one of the rarest Corvettes ever built, but with the reliability and punch of a modern supercharged drivetrain, this continuation Grand Sport makes a compelling case.
