This road-legal, V8 Jaguar C-X75 is the C-X75 we should have got

This is a Jaguar C-X75 resuscitated and re-engineered to live its life as a proper road-going supercar. It’s the second one bespokerised by Ian Callum’s company – unsurprisingly called CALLUM – and it’s also the second one that’s utterly gorgeous.

Though where the first one Callum did was a proper James Bond stunt car with numberplates and a massive V8, this one’s a… proper car. A Real Car. With insides and outsides and upsides and everything.

There’s still the not-so-small matter of a supercharged 5.0-litre Jag V8 lurking out back to torture the rear wheels, only now that riot of a powerplant is matched to a seven-speed dual-clutch gearbox.

And in this iteration, it gets Modes. Callum’s in-house software-istas programmed in a road-focused setup that gives it a “neutral, predictable balance through sweeping turns and arrow-straight stability where higher speeds are legally possible”.

There’s also a more dynamic sporting mode that naturally ups many antes, not least delivering sharper throttle responses and a fruitier exhaust tune.

Then comes the active aero pack, activated above 37mph, while an air brake acts as a… well, air brake. There are hydraulic lifters on the front suspension to help get the nose over speed bumps and kerbs and the like, and 20/21in front/rear wheels to keep well away from kerbs and the like.

The first Callum C-X75 adjusted a few panels here and there, whereas this new one has had over 1,000 hours of work poured into its body alone. Which again involved adjusting a few panels here and there, painting it in delightful shade of green (‘Willow’), fitting brushed-aluminium window surrounds, carbon fibre accents and a polished metal grille.

Inside, the stunt car’s bones have been ripped out, and replaced with a green and cream “premium environment”. A Real Car environment. Plush one, too. No ‘deploy villainous smile while drifting’ buttons here. Instead there’s a pair of custom seats wrapped in Bridge of Weir leather, a solid billet steering wheel, digital rear-view mirror, rotary controls, CarPlay, a cracking sound system – all the better to play the 007 theme on repeat – and even some cup holders.

“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,” said CALLUM engineering boss Adam Donfrancesco.

Quite. Ian Callum – who of course led the team that penned the original Jaguar C-X75 concept car – said: “C-X75 was ‘the one that got away’ – a car brimming with unfulfilled potential.

“We’ve combined the customer’s wishes with carefully engineered solutions to bring C-X75 to the thoroughly satisfying conclusion it always deserved.” An utterly gorgeous conclusion.
