Presented in 2010, the Jaguar C-X75 could have turned the Holy Trinity into a Holy Quaternity. It was approved for production, canned, sent to Hollywood, and largely forgotten about until recently. Ian Callum, who designed the coupe while running Jaguar’s design department, unveiled the first street-legal C-X75 earlier in 2024, and his company Callum Designs has just presented a second example with additional improvements.
Built for a customer, the second street-legal C-X75 started life as one of the stunt cars that survived the 2015 James Bond movie Spectre. Beyond the long list of modifications required to make the coupe legal for road use, Callum made numerous changes to the drivetrain, the active aerodynamic system, the styling, and the interior to bring the C-X75 closer to what it would have looked like had it reached production.
The C-X75 concept’s drivetrain consisted of two diesel-powered turbines that generated the electricity required to zap four electric motors into motion. That’s highly innovative but horribly complex and ultimately not very well suited to road use, so Callum replaced the entire system with a supercharged V8 engine linked to a seven-speed dual-clutch automatic transmission. Performance numbers aren’t available, but the company notes that it went through the trouble of developing two driving modes to ensure the C-X75 feels equally at home on the road and the track.
Although the low-slung proportions haven’t changed, Callum added a speed-activated air brake and an active aero package that provides downforce above 37 mph. The C-X75 should be easy to drive at lower speeds too, thanks to a front-axle lift system that ensures the one-of-four bumper doesn’t have a costly encounter with a speed bump. Willow Green paint and gray wheels add a finishing touch to the look.
There wasn’t much of an interior in the stunt cars, so Callum pretty much started from scratch. Peek inside and you’ll see an unbranded steering wheel machined from solid billet, an analog instrument cluster with a cool-looking gauge that tells the driver which gear the transmission is in, and a pair of sport seats upholstered with Bridge of Weir leather. Modern features that weren’t fitted to the stunt cars, such as a digital rear-view mirror, a wireless charging pad, and Apple CarPlay connectivity, are included. It looks like a tremendous amount of work went into the project.
Callum Designs hasn’t announced pricing, but it’s probably not cheap. Then again, we’re not talking about a run-of-the-mill hypercar: six units were built and only two are street-legal. The C-X75 makes low-volume cars like the Ferrari FXX-K look a little bit mundane, doesn’t it?
