Ian Callum's design studio has unveiled a track-focused GT1 interpretation of its reimagined Jaguar XJ220.
The new concept, finished in vivid yellow, adds aggressive aerodynamic elements to the already elegant supercar.

Callum describes the GT1 as a design study that celebrates the spirit of classic GT cars while exploring what that idea could become today.
The most striking changes are aerodynamic: a large front splitter, canards, more aggressive side skirts, and a massive rear wing rising from the rear fenders.
New wheels complete the track-oriented look.
The original XJ220, which once held the title of world's fastest production car, was powered by a 3.5-liter twin-turbocharged V6 producing 542 hp and 475 lb-ft of torque.
It could accelerate from 0-60 mph in 3.6 seconds and reach a top speed of 212.3 mph.
Whether the GT1 would retain this engine or adopt a new V12—as originally planned for the XJ220—remains unconfirmed.

A Modern Take on a Classic
Callum's redesign retains the XJ220's flowing silhouette but replaces all exterior panels.
Narrow LED headlights replace the original flip-down units, while the scuttle between the windshield and hood remains as a nod to the original.
Side fenders and doors have been reshaped, side air intakes enlarged, and the rear features a new decklid without the original spoiler, along with a revised diffuser and bumper.
Ian Callum, who designed iconic Jaguars like the XK, XF, and F-Type, never worked on the original XJ220.
His studio has now addressed that gap with this modern interpretation.
The firm has previously transformed two of the four C-X75 prototypes ever built, demonstrating its capability to modify rare supercars.

However, the GT1 remains a design study, and production would require an XJ220 owner willing to hand over their car for transformation.
