McLaren may be renown for the mind-bending performance of its supercars, but the company has been working on a dedicated grand tourer for a while now. The new model, now simply called GT, will be unveiled on May 15, but until then Woking is whetting our appetites with a teaser image of the undisguised rear end.

As we’ve seen in previous official “spyshots”, the GT will get a heavily sculpted rump with the slim, blade-like lights dramatically inset into the scalloped rear grille, together with a sizeable integrated spoiler, large air vents and a pair of simple, round tail pipes mounted low down.

A separate video has also given us a view of the sides and front of the car, and while certain elements, like the cab-forward proportions, curved headlights and shark-nose front end, are familiar McLaren cues, other items like the tall side air intakes – which form part of the rear haunches – are new to the brand.

Anyway, the GT will be its own distinct product, separate from McLaren’s Sports, Super and Ultimate Series of vehicles. Said to share its DNA with the Speedtail, it’s the fourth new car to be confirmed as part of the company’s Track25 business plan and will provide increased comfort and a more luxurious interior. It will likely be powered by the brand’s 4.0 litre twin-turbo V8, paired to a seven-speed dual-clutch transmission.

It’s not the first time McLaren has gone down the grand tourer path – in 2016, the company unveiled the 570GT, a more road-biased version of the 570S with a softer suspension setup and a sideways-opening glass hatch that covers a leather-lined luggage compartment above the engine.
