McLaren Senna GTR concept: uncompromising supercar gets even more extreme track-only version

Published: 06 March 2018

► Not road-legal
► Only 75 being made
► Tech details coming throughout the year

When McLaren unveiled the Senna supercar in 2017, it was billed as the most uncompromising road car the firm has ever made. Now there's a new version, called the Senna GTR – which is so uncompromising it isn't even road-legal.

Following on from previous track-focused McLarens including the F1 GTR and P1 GTR, just 75 examples of the McLaren Senna GTR will be made in Woking.

Given McLaren is building 500 regular Sennas, this means the new car is likely to appeal to both collectors and well-healed hardcore circuit fiends.We imagine the order book is over-subscribed already.

Announcing the new car at the 2018 Geneva motor show, McLaren boss Mike Flewitt explained: ‘Excelling on the track underpins the heritage of the McLaren brand and is as important and relevant today as it has ever been.’

He also underlined the exceedingly high performance the new car will have, saying: ‘The track-only McLaren Senna GTR will have more power, more grip and more downforce – up to 1,000kg – than the McLaren Senna and post even faster lap times.

'The very limited number of customers who secure this car will be buying the closest experience you can get to a race car without actually lining up on a circuit grid.’

Any exact details of the Senna GTR's performance?

McLaren reckons the only thing faster round a track than the Senna GTR will be a F1 car. But then, Aston Martin has said exactly the same thing about the Valkyrie AMR Pro...

Technical details will be released later in the year, but McLaren says the Senna GTR features the same core structure as the 'normal' car, and will weigh roughly the same amount, too. But it will still have a considerable amount of enhancement.

As if the enormous rear wing and diffuser combination didn't give that away.

At this stage we do know that power from the 4.0-litre twin-turbocharged V8 will be increased by 24bhp to a massive 813bhp, and that McLaren will also fit a race-style transmission, Pirelli slicks, and revised double-wishbone suspension.

Is there are more aggressive rear end on any current car? We don't think so

The aggressive aero, which also includes a vast front splitter, will also form a big chunk of the performance increase, helping to produce up to 1000kg of downforce.

More info on the McLaren Senna GTR will be released throughout 2018, so we’ll update this page as we know more.
