Jaguar's long-awaited concept car has been leaked online ahead of its official unveiling overnight.

Images posted to online forum Coche Spias give a first look at the low, sleek electric GT car, which previews the design language that will define Jaguar's three new-era EVs, beginning with a similarly proportioned luxury saloon next year.

The concept will be officially revealed at Miami Art Week overnight tonight (2-3 December).

Clearly, it is completely unrelated to any Jaguar model that has gone before – making good on the company's ambition for its cars to be "a copy of nothing".

Its monolithic, minimalist silhouette is defined by a long, probing bonnet, which calls to mind some of Jaguar’s biggest-engined past models and lends the concept a distinct cab-rear stance.

The A-pillars are effectively invisible and the side windows narrow towards the rear, giving the glasshouse a wraparound effect reminiscent of a racing helmet.

As revealed by Autocar previously, it has a bluff front end with a prominent ‘grille’ motif and a new lighting signature comprising ultra-slim LED strips at each edge.

The arches, meanwhile, are dramatically swollen to accommodate large-diameter, wide-set allow wheels - and the new Jaguar emblem features just aft of the front wheel on a gold panel, which houses a rear-view camera on each side.

It needs cameras because there is no rear window, as had been recently previewed by Jaguar, and the back end is dominated by a large vent-style pattern - one of the four defining motifs that form part of Jaguar’s new visual branding signatures.

These cues are set to feature prominently in the Jaguar's upcoming four-door electric GT, which will be the first in a three-car line-up due from 2026.

The production car, which recently began road testing, will pack north of 575bhp and have a range of more than 430 miles. It will be priced in excess of £100,000, positioning it as a rival for the Porsche Taycan.
