Fourth new model under the 'Track25' business plan to be revealed 'in just a few months', and will be based on the Speedtail.

McLaren Automotive has previewed a new GT model that it plans to release later this year, with company CEO, Mike Flewitt, making the announcement at the Geneva motor show.

"The fourth McLaren to be introduced under the Track25 business plan will be our interpretation of the Grand Tourer. It will be a car that combines competition levels of performance with continent-crossing capability, wrapped in a beautiful lightweight body," Flewitt said.

"It’s a car that has been designed for distance and one that will also provide the comfort and space expected of a Grand Tourer. But with a level of agility never experienced before in this segment. In addition, it will be the lightest of Grand Tourers and by also having the best power-to-weight ratio, I promise it will be one of the quickest."

"In addition, it will be the only Grand Tourer to share its DNA with the 250mph McLaren Speedtail," he added.

The new model's name is yet to be revealed, along with its final design, though an image of a camouflaged prototype was supplied by the British supercar specialist (top).

Given that McLaren has confirmed the new GT will share 'DNA' with the Speedtail, expect it to be powered by a hybrid powertrain. The Speedtail combines a 4.0-litre twin-turbo V8 and electric motor for a system power output of 772kW, for reference.

Flewitt noted the new McLaren GT won't form part of any existing model 'Series', though we'd expect it to sit at the upper end of the company's line-up.

More information will come to hand in the months ahead, so stay tuned to CarAdvice for all the latest.
