The Chevrolet Corvette C7 GT3-R represents an ambitious European interpretation of America’s iconic sports car, combining traditional big-displacement V8 performance with the engineering and aerodynamic development required for international GT3 competition. Built by German-based Callaway Competition, this exceptionally rare racing machine was developed specifically for FIA GT3 competition, with just eight examples produced.
This particular 2018 Corvette is finished in a distinctive yellow-and-black Kennol racing livery, complemented by extensive carbon-fiber bodywork designed to improve aerodynamic efficiency while reducing weight. Although its American origins are unmistakable, the car’s development and competition pedigree reflect Callaway’s considerable experience adapting the Corvette platform to the demands of European endurance and GT racing.
APP Racing-Built 7.0-Liter LS7 V8
At the heart of the C7 GT3-R is an APP Racing-built 7.0-liter LS7 V8, a competition-focused development of Chevrolet’s naturally aspirated small-block architecture. The engine features an aluminum block, dry-sump lubrication system and Bosch programmable engine management, combining proven mechanical fundamentals with sophisticated electronic control.
The 7.0-liter displacement provides the substantial torque characteristics associated with Chevrolet’s large-capacity V8 engines, while the dry-sump system ensures consistent oil delivery under the sustained high lateral loads encountered during circuit driving. Bosch engine management further allows precise calibration of the powertrain for competitive use.
Rather than relying on forced induction or hybrid assistance, the Corvette delivers its performance through naturally aspirated displacement and an unmistakable V8 soundtrack.
Raw Racing Action at Mugello
The onboard footage captures the car during the Gran Premio Storico d’Italia at Mugello Circuit, an event organized by HVM Racing and Masters Historic Racing. More than a static showcase of its engineering, the video provides an opportunity to experience the C7 GT3-R operating at speed, with unfiltered engine sounds and the mechanical intensity of a purpose-built racing car.
The sequence begins with engine startup and warm-up before following the Corvette through the pit lane, where acceleration provides an early demonstration of the LS7’s distinctive exhaust note. Trackside footage then captures the car at speed before the perspective moves onboard for a lap of Mugello.
The circuit’s combination of fast corners, elevation changes and demanding braking zones offers a fitting environment to appreciate the Corvette’s aerodynamic package and chassis capabilities. Additional external footage precedes a second flat-out onboard lap, allowing viewers to experience the car’s performance from both perspectives.
A Rare European Corvette
With only eight Callaway Competition C7 GT3-R examples built, this machine occupies a distinctive position in modern Corvette racing history. It demonstrates how the C7 platform could be transformed into a specialized international GT competitor while retaining the character of Chevrolet’s naturally aspirated V8 heritage.
For enthusiasts, this video is particularly compelling because it captures the car without commentary or artificial sound enhancement. The result is an authentic look at one of the rarest competition Corvettes, with the 7.0-liter LS7 providing the soundtrack.
