Legendary British designer Ian Callum has transformed the Jaguar C-X75—originally a concept supercar and James Bond stunt vehicle—into a fully road-legal, high-performance machine. Built on one of the four C-X75 models created for Spectre, this re-engineered vehicle, known as Car 001, marks Callum’s second customer commission. Equipped with a supercharged 5.0-litre Jaguar V8 engine and a seven-speed dual-clutch gearbox, the C-X75’s modern iteration delivers both power and exclusivity. Callum’s design firm has enhanced the car with hundreds of modifications, including active aerodynamics, a revamped contemporary interior, and an all-new drivetrain, ‘producing a capable, refined and elegant supercar.’ A Thousand-Hour Overhaul in PrecisionThe Callum-commissioned C-X75 underwent over 1,000 hours of precise bodywork refinements, transforming the former stunt car into a fully functional supercar. Key exterior modifications include reducing panel gaps and applying a bespoke Willow Green paint. The team added brushed aluminum window surrounds, a polished metal grille, a custom filler cap, and carbon fiber accents on the diffuser and intake. The taillights now feature improved light diffusion, with a C-X75 emblem etched onto the tailpipe. Original grey alloy wheels—20 inches at the front and 21 inches at the rear—complete the car's updated look. Inside, the original bare stunt car cabin has been reimagined into a luxurious green and cream interior. Custom Bridge of Weir leather seats, selected by the commissioner, add a sense of opulence. The cockpit features a billet aluminum steering wheel, two dials housed in a custom binnacle, and a roof-mounted console for key controls, including the engine start button. Rotary controls aimed toward the driver enhance ergonomics, while amenities like Apple CarPlay, a wireless charging pad, and a bespoke sound system bring modern comfort. Cupholders are integrated within the sills, blending practicality with design. Reflecting on the project’s technical challenges, CALLUM’s engineering boss Adam Donfrancesco explained, “Integrating features including aircon and premium audio whilst also balancing the NVH, refinement and hygiene factors such as engineering the door seals to keep the elements out, all whilst ensuring it still sounded mega, was a formidable but thrilling challenge and the results speak for themselves.” Performance UpgradesThe Callum-commissioned Jaguar C-X75 has the Spectre-sourced supercharged 5.0-litre V8 engine, now paired with a seven-speed dual-clutch transmission that delivers power exclusively to the rear wheels. Callum’s engineers refined the powertrain with new software, enhancing its responsiveness for daily use and introducing a dual-mode system. In standard mode, the car provides a balanced, predictable drive, while the dynamic sport mode sharpens throttle response, accelerates gear shifts, and amplifies exhaust acoustics, tuned by an acoustic expert for a richer, more engaging sound. Suspension adjustments were also a focus, with extensive testing leading to a setup that balances stability and agility. A hydraulic front lift system, newly integrated into this model, allows the C-X75 to navigate urban obstacles like steep ramps and speed bumps with ease. Callum’s active aerodynamics package, designed specifically for this C-X75, activates above 37 mph, deploying additional downforce for increased stability on open roads. The rear air brake further enhances control, helping to manage deceleration at high speeds. The One That Got AwayReflecting on the C-X75, Ian Callum describes it as “the one that got away”—a groundbreaking concept from 2010 brimming with “unfulfilled potential.” With this second bespoke commission, Callum and his team have now brought that vision to what he calls “the thoroughly satisfying conclusion it always deserved.” While the cost of this transformation remains undisclosed, such extensive modifications clearly don’t come cheap. With only two of the original four Spectre stunt cars remaining, there is the potential for further bespoke builds, should their owners choose to undertake a similar project with Callum’s UK-based firm.
