Here at The Coolector, we have an unapologetic weak spot for rare, high-octane vintage racers—especially when they combine the dramatic flair of Italian bodywork with the unbridled grunt of American V8 muscle.

When it comes to titan figures in sports car engineering, few names shine brighter than Giotto Bizzarrini. After spearheading legendary competition machines like the immortal Ferrari 250 GTO and refining the Iso A3/C, Bizzarrini set out on his own quest to create the ultimate open-top racing prototype.

The result of that vision was the P538, an incredible mid-engine barchetta designed to take on the world’s most grueling endurance circuits.

Headed to the auction block via RM Sotheby’s with an estimated value of $450k+ ($450,000–$550,000), this extraordinary 1976 Bizzarrini P538 represents a genuine, authenticated piece of motorsport heritage ready to conquer the track once again.

Corvette Power Meets Giugiaro Design

When the P538 concept originally debuted at the 1966 24 Hours of Le Mans, it immediately turned heads across the paddock.

Rejecting traditional Italian V12 engines in favor of Chevrolet’s bulletproof, torque-heavy 5.3-liter V8, Bizzarrini forged a ferocious mechanical hybrid.

The low-slung, sweeping bodywork was penned by none other than a young Giorgetto Giugiaro, resulting in one of the most visually arresting silhouette profiles of the era.

* Engine Core: Mid-mounted 5.3-Liter Chevrolet V8
* Designer: Giorgetto Giugiaro (Bodywork fabricated by Rosanna Bizzarrini)
* Authenticator: Marque expert Jack Koobs de Hartog & Giotto Bizzarrini
* Track Status: Transferable invitation to 2026 Goodwood Revival

Ever the creative mind, Bizzarrini cleverly interpreted FIA prototype regulations by positioning the driver centrally inside the cockpit, flanked by a passenger pod on one side and a GT-mandated luggage space on the other.

It was an audacious, performance-first layout that cemented the P538’s mythical status among racing purists.

Verified Provenance and Master Craftsmanship

Though financial troubles forced Bizzarrini’s original company to fold in 1070, the designer never truly lost his passion for the P538 layout.

Discovered in France in the early 1990s, this specific chassis underwent rigorous research to verify its origins.

In 2009, renowned marque expert Jack Koobs de Hartog presented detailed documentation and photographs of the unrestored frame directly to Giotto Bizzarrini himself.

“Upon reviewing the frame, Giotto Bizzarrini immediately recognized the unmistakable hallmarks of his own handiwork—confirming he had constructed the chassis in the 1970s and that his wife, Rosanna, had personally fabricated the bodywork to Giugiaro’s original design.”

Following this historic confirmation, the car underwent a comprehensive, ground-up restoration in 2015 to return it to its period-correct glory.

Holding both an FIA Historic Technical Passport and a FIVA Identity Card, this P538 stands out as an extraordinarily authentic, genuine Bizzarrini-built creation.

Bound for the Whitsun Trophy

Far from being a static museum piece, this Bizzarrini is built to be driven hard.

Having already proved its mettle on track at the 2023 Goodwood Revival under its current custodian, the car comes accompanied by a priceless asset for historic racing enthusiasts: a transferable invitation to compete in the 2026 Goodwood Revival Whitsun Trophy.
