Jaguar C-X75 Reimagined: CALLUM’s Ultimate Makeover Of A Lost Masterpiece

CALLUM has achieved the extraordinary by bringing a Jaguar C-X75 concept car to life in a one-of-a-kind bespoke commission. This supercar, which never made it to full production, is now transformed into a road-ready masterpiece with tailored enhancements, striking design, and exhilarating performance. A symbol of engineering prowess, this unique Jaguar C-X75 showcases CALLUM’s dedication to realising unfulfilled potential in one of the most admired car designs of the last decade.

A Dream Realised: The C-X75 Brought to Life

Originally conceived as a concept, the Jaguar C-X75 was intended to represent the future of performance and design for Jaguar. Despite its promise, it remained one of “the ones that got away” – never reaching production. Enter CALLUM, a company founded by legendary designer Ian Callum, which took on the mission to fulfil the car’s unrealised potential. Their latest project goes beyond merely readying the C-X75 for the road, reimagining it as an ultimate road-going supercar.

Highlights of the C-X75 Commission by CALLUM

Here’s a look at what makes this CALLUM-commissioned C-X75 an extraordinary achievement:

  • Enhanced Performance: Upgraded drivetrain, active aerodynamics, and customised suspension.
  • Distinctive Design: A refined exterior in Willow Green with bespoke touches.
  • Personalised Interior: Luxurious, driver-focused cabin featuring high-quality materials and tailored finishes.

Bringing Performance to the Forefront

CALLUM’s engineering team worked closely with the car’s owner to infuse the C-X75 with modernised power and handling capabilities.

Upgraded Drivetrain and Transmission

At its heart, the C-X75 now houses a supercharged V8 engine paired with a seven-speed dual-clutch transmission. CALLUM developed in-house software to allow the car to seamlessly transition between road-friendly and high-performance modes. When switched to its sporting mode, gear changes are sharp, throttle response is immediate, and the exhaust roars with a custom-tuned soundtrack that provides an intense driving experience.

Active Aerodynamics for Stability and Agility

The bespoke aerodynamics package enhances stability at higher speeds. At over 60 km/h, active aero components generate additional downforce, providing more confidence during fast cornering and straight-line stability. A hydraulic front-lift suspension ensures that the car remains practical in urban environments while retaining its sporting pedigree.

Exterior: Craftsmanship in Every Detail

A key aspect of the commission was a meticulous approach to the exterior. Over 1,000 hours went into perfecting the bodywork, including precise panel alignment and a striking paint finish in Willow Green. This colour, inspired by the natural hues of willow leaves, combines earthy tones with a hint of yellow for an elegant effect.

Distinctive touches include:

  • Window Surrounds: Machined from solid aluminium and brushed for a sleek finish.
  • Carbon Fibre Accents: Featured on the quarter-light intakes and diffuser, adding a touch of performance styling.
  • Etched Emblems: A unique C-X75 insignia adorns the exhaust, while custom lighting enhances the rear for a refined, cohesive look.

Interior: A Refined and Driver-Focused Experience

Inside, the C-X75 has transformed from a functional stunt car into a luxurious, bespoke cabin that reflects both style and comfort.

Fusion of Dark and Light Tones

The cabin’s interior is a harmonious blend of dark green and cream, separated by a bold, angular “waterline” that adds visual dynamism to the space. This unique choice balances sporting intensity with comfort, creating an interior that’s as refined as it is driver-focused.

Advanced Tech and Customised Features

CALLUM has infused the interior with modern conveniences, including:

  • Wireless Charging and Apple CarPlay: Integrated for seamless connectivity.
  • Bespoke Sound System: Includes carefully placed subwoofers and a hidden centre speaker, delivering immersive sound quality.
  • Digital Instrument Cluster: A sleek acrylic cowl covers the digital display, adding to the cabin’s minimalist aesthetic.

Built for Driving Comfort and Precision

From its seats to its steering wheel, every element of the interior has been tailored for optimal driving enjoyment.

  • Custom-Machined Steering Wheel: Made from solid billet and designed to the owner’s specifications.
  • Premium Leather Seats: Upholstered in Bridge of Weir leather for support and comfort, complete with three-point seat belts.
  • Aircraft-Inspired Console: All essential controls, including the start button, are located on a roof-mounted console, a unique nod to aviation design.

Engineering the Ultimate Road-Ready Supercar

Transforming a raw stunt car into a sophisticated supercar presented challenges, but CALLUM’s team saw this as an opportunity to create something truly exceptional.

Striking a Balance Between Power and Refinement

Achieving the perfect balance between noise, vibration, and harshness (NVH) while retaining the car’s thrilling sound was a priority. The engineering team incorporated a bespoke exhaust system to amplify the C-X75’s roar while maintaining comfort during everyday driving.

Innovations in Additive Manufacturing

In partnership with Stratasys, CALLUM used advanced 3D printing techniques to craft custom interior elements that enhance both function and style. Highlights include innovative sill trim that discreetly incorporates cup holders, a detail that exemplifies CALLUM’s dedication to blending practicality with beauty.

Can a Supercar Be Both Art and Engineering?
