Jet-powered cars have captured the imagination of racing enthusiasts since their inception. These vehicles, powered by jet engines originally designed for aircraft, have pushed the boundaries of speed and technology in motorsports.
The concept of jet-powered cars in racing dates back to the 1940s and 1950s.
Fast forward to 1967, and the STP-Paxton Turbocar, equipped with a Pratt & Whitney turbine engine, captures everyone’s attention, challenging traditional race cars. Despite facing technological hurdles like throttle lag and regulatory pushback, these innovations left an indelible mark on motorsport.
Early Experiments
In the early 1950s, manufacturers like Rover and Fiat began experimenting with gas turbine-powered cars, marking the dawn of jet-powered racing. Rover’s JET1, introduced in 1950, was the first of these jet cars, paving the way for future advancements in turbine technology. This early experiment demonstrated the potential of gas turbines in automobiles despite challenges such as fuel efficiency and overheating.
Fiat followed with its Turbina in 1954, encountering similar issues with high fuel consumption and heat management, which hindered its competitive success. Despite these setbacks, these early experiments were significant in the history of jet-powered vehicles.
Renault’s Etoile Filante made a significant mark in 1956 at the Bonneville Salt Flats. With its gas turbine engine, it set a speed record, showcasing the impressive performance capabilities of jet cars. This achievement highlighted the potential of turbine power in racing, inspiring further exploration and development.
Throughout the 1950s, other manufacturers like GM and Chrysler also explored gas turbine technology. Their efforts contributed to the evolving history of jet-powered cars, setting the stage for future innovations in the world of racing.

The 1967 STP-Paxton Turbocar
The 1967 STP-Paxton Turbocar revolutionized the Indy 500 with its compact yet powerful Pratt & Whitney turbine engine, generating over 550 horsepower. Designed by engineer Ken Wallis, this groundbreaking racecar featured an innovative all-wheel-drive system and a distinctive electric red color. Traditionalists at the Indy 500 were skeptical of the Turbocar, which emitted a whoosh sound rather than the familiar roar of piston engines.
Driver Parnelli Jones showcased the Turbocar’s potential by leading most of the 1967 race. However, a mere $6 transmission bearing failure dashed his hopes for victory, allowing A.J. Foyt to clinch the win. Despite this setback, the Turbocar left an indelible mark on racing history.
Here’s a snapshot of the key players and moments:
| Driver | Car | Outcome |
|---|---|---|
| Parnelli Jones | 1967 STP-Paxton Turbocar | Led but lost |
| A.J. Foyt | Traditional racecar | Won |
| Ken Wallis | Designer of Turbocar | Innovation |
The Granatelli jet car’s legacy was short-lived. By 1970, restrictions on air volumes and drivetrains eliminated jet cars from competitive racing, relegating them to a fascinating yet brief technological curiosity in the annals of the Indy 500.
Technological Innovations
Jet-powered cars introduced a wave of technological innovations to the racing world, fundamentally transforming how engineers approached speed and performance. Using compact Pratt & Whitney turbine power plants capable of generating over 550 horsepower, these race cars demonstrated remarkable engineering skills. The turbines produced a distinctive whoosh sound, differentiating jet-powered cars from the traditional roaring engines typically heard on the track.
In drag racing, innovation extended beyond the power plant. Jet-powered cars featured advanced all-wheel-drive systems, significantly improving handling and stability. This enhancement allowed drivers to push speed boundaries with greater control, resulting in thrilling races. However, these technological marvels faced challenges. Throttle lag in the turbines posed issues, limiting their effectiveness on various racing circuits.

Notable Races and Drivers
Jet dragsters, with their thunderous speed and futuristic designs, captivated audiences and pushed the boundaries of automotive performance. Icons like Art Arfons and Craig Breedlove became synonymous with these high-velocity machines.
Art Arfons, with his jet dragster, the Green Monster, became a household name in the 1960s. He relentlessly pursued land speed records, continually modifying his jet-powered car to achieve greater speeds. His rivalry with Craig Breedlove fueled a golden era of speed racing at the Bonneville Salt Flats in Utah.
Craig Breedlove, another legendary figure, achieved multiple land speed records in his jet-powered cars, breaking the 400, 500, and 600 mph barriers. His achievements weren’t just about numbers; they represented human determination and innovation. He set a world land speed record of 407.447 mph in 1963, a record that he would continue to break, ultimately reaching 600.601 mph in 1965. Similarly, Art Arfons’ Green Monster set multiple records, including a top speed of 576.553 mph in 1965.
Meanwhile, Lee Breedlove, Craig’s wife, set a speed record for women in a jet-powered vehicle, highlighting the inclusivity of the racing world.
These drivers and their incredible machines brought jet-powered cars into the limelight, leaving an indelible mark on racing history. Their achievements continue to inspire awe and admiration among racing enthusiasts worldwide.
