The Birth of a Legend: Chevrolet Corvette EX87
In the ever-evolving world of automotive technology, test mules have always played a crucial role. These vehicles are often modified versions of existing models, used by manufacturers to test new technologies and powertrains. While many of these test vehicles are eventually destroyed or kept as private collectibles, some, like the Chevrolet Corvette EX87, capture the public’s imagination and become legends in their own right.
From Humble Beginnings to Record-Breaker
The early Chevrolet Corvette C1 was not an immediate hit with consumers, which prompted legendary engineer Zora Arkus-Duntov to take action. He proposed using the Corvette to break the speed record held by the Chrysler 300 at the time. To achieve this, Indy 500 winner Mauri Rose was brought on board. Together, they began modifying an unsold 1954 Corvette for high-speed performance.
The resulting vehicle, the Corvette EX87/5951, was equipped with a 307 cubic inch V8 engine paired with a special high-lift cam. This was a significant step forward, as it predated the introduction of the 265 cubic inch small-block V8 in 1955. The car featured a low windshield and unique underbody panels, enhancing its aerodynamic profile. The EX87/5951 reached speeds of up to 163 mph at the GM Arizona Proving Ground, setting the stage for an official record attempt at Daytona Beach.
The Retro Charm of a Historic Vehicle
Today, the Corvette EX87/5951 exists as part of the Lingenfelter Collection, occasionally making appearances at various automotive shows. The car’s body, originally paired with the 1955 Corvette frame #6903, has been restored and is now a testament to its rich history. After its original 265 cubic inch engine failed, a 327 cubic inch V8 engine was installed, and the car was repainted red in the 1970s. The odometer shows about 21,000 miles, but the true mileage remains a mystery.
The Ongoing Legacy of the Corvette EX87
Test mules like the Corvette EX87 are more than just vehicles; they are stories of innovation and ambition. The introduction of the V8 engine in the Corvette was a pivotal moment in automotive history, and the EX87 played a crucial role in that evolution. The current owner of the EX87 has acquired not only a piece of automotive history but also a collection of GM’s historical correspondence, service records, spare parts, and a formal title from California.
As of the writing of this article, the Corvette EX87 is up for auction with a current bid of approximately 70 million KRW (around $58,000 USD). The true value of such a historically significant vehicle is difficult to quantify, but as the auction concludes, its worth will be determined by those who understand its legacy.
Reflecting on Automotive Innovation
The story of the Corvette EX87 is a reminder of the importance of innovation in the automotive industry. It highlights how test mules can lead to groundbreaking developments that shape the future of cars. The EX87’s journey from a modest test vehicle to a cherished classic exemplifies the enduring appeal of the Corvette brand and its impact on the world of performance vehicles.
As we look to the future, the lessons learned from vehicles like the EX87 continue to inspire new generations of engineers and designers, ensuring that the spirit of innovation remains alive and well in the automotive industry.
