The Jaguar C-X75 concept from 2010 may have never reached production, but there are four surviving examples from the 2015 James Bond movie Spectre in the hands of collectors. UK-based firm Callum, founded by the designer of the C-X75, undertook the makeover of a second movie car, including exterior refinements, active aero, a re-engineered drivetrain, and an overhauled cabin. The new project follows the first commission from February 2024, meaning that two of the four C-X75 prototypes have already received the Callum treatment resulting in a street-legal status. The new build – based on the Car 001 – is said to be the most refined yet, thanks to a wide range of modifications.

Ian Callum described the Jaguar C-X75 as “the one that got away”, adding that it is “brimming with unfulfilled potential”. As for the new conversion, the designer said: “We’ve combined the customer’s wishes with carefully engineered solutions to bring C-X75 to the thoroughly satisfying conclusion it always deserved.” The team spent over 1,000 hours perfecting the bodywork. The panel gaps were reduced, and the car was repainted in Willow Green. Other details include the brushed aluminum window surrounds, the polished metal grille, the bespoke filler cap, and the carbon fiber accents at the rear. Finally, the taillights have been enhanced in terms of light diffusion, and a C-X75 emblem has been etched on the tailpipe. Callum’s tweaks didn’t only make the supercar more beautiful. A new active aerodynamics package is said to increase stability and handling while adding an air brake function. The 20-inch and 21-inch alloy wheels of the prototype are carried over.

 

Moving on to the interior, the spartan cabin of the movie car has been transformed into a luxurious, modern, and comfortable space. The dashboard, center console, and switchgear have been redesigned, along with a custom steering wheel and new bucket seats. The latter are upholstered in Bridge of Weir leather, featuring dark green and cream tones. The tactile rotary controls on the inclined center console feature integrated touchscreens, with all other functions controlled by a roof-mounted panel. Technology has been upgraded with a wireless charging pad, Apple CarPlay integration, a bespoke sound system, and a digital rearview mirror. More importantly, Callum engineers added an air-conditioning system and improved the NVH levels of the supercar.

The Jaguar C-X75 retains the original supercharged 5.0-liter V8 engine, which is now mated to a new seven-speed dual-clutch automatic transmission, sending power to the rear wheels. New software and electronics make the supercar more usable in everyday driving, with a more dynamic sporting mode available on command. The latter sharpens the gear shifts and throttle response while making the exhaust louder. The suspension setup has been tweaked following extensive testing. Furthermore, a hydraulic front lift system was added, allowing the supercar to go over steep ramps or speed bumps without scraping the underbody.

Callum didn’t reveal the cost of the upgrades for the second Jaguar C-X75 prototype, but those things don’t come cheap. It remains to be seen if the owners of the remaining two movie cars will also pay a visit to the UK-based firm for a similarly bespoke treatment.
