The Corvette Grand Sport has one of the most daring stories in American racing. In 1962, Corvette chief engineer Zora Arkus-Duntov set out to build a lightweight, high-powered car that could take on Europe's best. Only five prototypes were made before the project was shut down, but those cars quickly became legends.

So, what is a Corvette Grand Sport today? 

It's a licensed GM continuation model built by Superformance — a faithful recreation of the original that combines old-school racing spirit with modern materials and engineering. It's a car for drivers who love history but don't want to sacrifice performance or reliability.

What Makes the Grand Sport Corvette Exceptional?

Authentic Chassis & Suspension

An original-style tube chassis paired with independent suspension and a period-correct rear transverse leaf spring brings the true Grand Sport driving feel to life. While faithful to the original design, the suspension benefits from refined engineering, offering both authentic handling and improved performance over the 1960s racers.

Hand-Laid Fiberglass Body

Every detail, from clear headlight covers to leather hood straps and the aggressive, wide front and rear fenders, mirrors the original racers. This wide-body design was a hallmark of the Grand Sport, giving it a commanding, race-ready presence.

Braking & Cooling Power

Wilwood 4-piston disc brakes, a stainless steel fuel tank, and an aluminum radiator with electric fans deliver top-tier reliability on track or street.

Interior Craftsmanship

Inside, you'll find a classic Corvette dash, vintage-style steering wheel, race seats, and high-end leather finishes, available with optional diamond stitching and custom piping.

Customization Options

From twin stripes and roundels to blackout packages and custom paint, the Grand Sport can be tailored to match your exact vision. While it doesn’t follow modern trim levels, Superformance offers a wide range of custom options and packages that let you personalize everything from performance upgrades to interior finishes.

Wheels & Exhaust Choices

Select from 15" magnesium wheels or modern 17"/18" Halibrand-style alloys, wider wheels for enhanced stability and performance, or striking black wheels for a bold, aggressive look. Pair them with Michelin Pilot Super Sport tires for superior grip on track or street.

Engine & Transmission Compatibility

While inspired by the original small-block V8s, the Superformance chassis can accept a wide range of modern powerplants, including LS-series and E-Rod crate engines, offering vintage looks with modern performance.

What Is the Difference Between the Original Grand Sport and the Superformance Grand Sport?

The original Corvette Grand Sport was a series of five GM prototypes built in the 1960s by Zora Arkus-Duntov to compete in racing events. These cars were never mass-produced, with only a handful ever built.

The Superformance Grand Sport is an officially licensed continuation model designed to replicate the original Grand Sport's styling and racing heritage but with modern build quality, materials, and drivetrain options. It offers more flexibility in terms of powertrain, allowing for upgrades like modern LS and E-Rod crate engines. It stays true to the original design elements like the lightweight fiberglass body, wide fenders, and classic race-inspired features.
