New GTR produces at least 814bhp and 1000kg of downforce; firm claims 'only an F1 car is faster on track'

More than 150 people expressed interest in buying a Senna GTR at the recent Geneva motor show, according to a McLaren spokesman.

"With a maximum of 75 being produced, we can say with some certainty that it’s sold out", the spokesman told Autocar.

This suggests all buld slots for the car, which will be priced from £1.2 million, could be spoken for as soon as the car goes on sale.

To produce the GTR, McLaren let its racing engineers loose on its newest supercar and the result is a 1000kg of downforce-producing track-monster that’s more focused than even the P1 GTR.

Described as the fastest machine to roll out of Woking this side of a Formula 1 car, the concept is a preview for what's to come when an extreme take on the formidable Senna Super Series model is launched.

Autocar's Matt Prior has taken an up-close look at the Senna GTR. Check out this video:

In the GTR, the Senna’s twin-turbocharged 4.0-litre V8 has been reworked so it now produces “at least” 814bhp – up from the standard car’s 789bhp. It sends drive through what the brand calls a “race-style transmission”.

Opinion: Why the world needs more cars like the McLaren Senna GTR

McLaren P1 GTR review

A spokesman told Autocar that it was too early to confirm exactly what this meant, but it suggests the car will use something of higher specification than McLaren’s regular seven-speed dual-clutch gearbox, which is featured in the standard Senna.

Also unconfirmed but likely is an advanced adjustable traction control system. This technology would enable drivers of varying abilities to progressively alter an electronic safety net that controls torque to the driven wheels; such a system was used on the P1 GTR.

McLaren says the Senna GTR will out-accelerate a standard Senna but it has yet to confirm straight-line performance figures. The regular car can charge from zero to 62mph in 2.8sec and takes a total of 6.8sec to reach 124mph.

With no road regulations or pedestrian safety tests to worry about, McLaren’s aerodynamicists have extracted a further 200kg of potential downforce from the Senna’s body. They’ve gently resculpted its panels, added an enormous front-splitter and bolted on a rear diffuser that shames those used by Le Mans GTE racers. Add the Senna’s active rear wing and downforce now peaks at 1000kg, 400kg more than the P1 GTR.

To help road-holding, the Senna GTR also features a wider track than the standard car, as well as a maximised front splitter and rear diffuser.

To handle these enormous high-speed loads, the Senna GTR uses revised double wishbone suspension and Pirelli slick tyres. A carbonfibre Monocage III skeleton remains at the car’s core, but the GTR is expected to be around 50kg lighter than the 1198kg Senna when dry, because it can do away with road-specific kit such as airbags, a handbrake and an exhasust muffler, and can make use of lightweight materials such as plexiglass.

Aston Martin Vantage GTE "proves transferable tech"

This means the GTR will produce more than 596bhp per tonne, which would be 108bhp fewer than the hybrid P1 GTR. However, the Senna GTR is an more track-focused package that its makers say can lap McLaren’s test circuit quicker than anything else it has built with a roof. McLaren says only its F1 cars can clock a quicker time.

McLaren Automotive design engineering boss Dan Parry-Williams said this level of pace was possible because the Senna was designed “with the full spectrum of road and track requirements in mind” from the outset.

“The McLaren Senna GTR concept unveiled in Geneva is not the finished article but it does give a clear indication of our thinking for the car, which promises to be the most extreme and exciting McLaren to drive for many years, if not ever,” he said.

The GTR, which is the latest in a lineage that started with the 1995 24 Hours of Le Mans-winning F1 GTR, will be priced from £1 million before taxes (so that’s £1.2m including VAT in Britain) and hand built at McLaren’s Production Centre.

The GTR promises the performance of the Aston Martin Valkyrie and Mercedes Project One for around half the price.

It is the only remaining version of the Senna currently on sale because all 500 examples of the regular car have been allocated; that model started at £750,000.

A grossly excessive output of new versions, and new versions of versions.

 

The saturation of releases and launches has led to near-zero impact each time. 

 

When cars like F40 and F1 were launched, their impact was felt for years afterwards, and cultivated a clear image and idea.  I still deep down like cars, but this relentless new model of the week thing is unreadable and deeply boring.

 

Why bother today, when you know there is faster/more expensive/even uglier model coming tomorrow?

26 March 2018

Less is more. Get it right the first time and it's hard to see why repeated tweaks are anything more than a way of chiselling the customer.

"firm claims 'only an F1 car is faster on track" So this is supposedly faster around a track than a LMP1H sports-prototype like a Toyota TS050 then? 

6 March 2018

1. I thought that the original McLaren Senna was the ugliest car I'd ever seen. I was wrong

2. 'firm claims 'only an F1 car is faster on track''. Bit of a misleading headline when further down it clearly says McLaren say it is faster than anything THEY'VE built apart from their own F1 cars. So its faster than a 720S and P1

3. So if the original Senna was an extreme and brutal track car, is this an extremely extreme and brutally brutal super-track car. I'm confused

4. Despite all of its extremely extreme brutal brutality wannabe badass marketing hype, that Aston Valkyrie track car thing will just stroll over, put it against a wall, and take it's dinner money

5. Seriously just look at it. Its the kind of thing my toddler would make in Lego

1. They state it is the fastest car 'they' have built with a roof. McLaren. Not any other manufacturer.

2. The Senna is a track car legitimised for the road. The Senna GTR is a Senna Plus if you like due to removing the airbags, etc. It's track only. What's hard to understand?

3. Yes, the Valkyrie will no doubt crush it, but that is way more expensive. It might be its nearest competitior, but in no way a like-for-like competitor. Saying this car is slow is like saying I've only got 6 billion, I'm poor compared to Bill Gates. You'd still be rich and this car is still FAST!

4. Not trying to be a smart arse myself, but the moaning comments on here are what's boring. Times change, we live in a quicker-moving world for better or worse. Faster prototyping, etc. We've never lived in a better time to enjoy cars. Seriously, do you want to go back to a crank start? Why not try being positive and even enjoing the fact we have a world-class car company to be proud of?

Can't agree more, usually the sour grapes imho. 

If you don't look back at your car after you parked it, you own the wrong car.

Regardless of all that blathering. McLaren's lack the one thing cars such as this should have, and that's a soul or character. Italian cars can do it. And that name is cringingly embarrassing.

26 March 2018

Yes, stop the moaning. Imagine complaining about there being too many exciting hypercars being launched. Jeez. Some are better than others, sure. And most of us can only hope to see one, never mind drive or own one, but surely it's great to find out what's happening at the cutting-edge of performance?

I hate the fact that society is so divided with the super-rich hiding their money from the taxman etc... but these machines are designed and built by folk like us and we can all take pleasure in the incredible creations they come up with (even if they'll be mostly bought by a bunch of bams with secret bank accounts in dodgy places). 

 

26 March 2018

Most won't even be driven, most will be bought by people who don't even like driving, who employ someone to do this for them, and who probably want little more than something else to show off about before they sell it on for a huge premium (with no tax payable on the gain, of course, and no need to hide the profits offshore, because HMRC still thinks cars are a depreciating asset).

26 March 2018

The usual negative bores outwitted by a clickbait synopsis.

I don't particularly like the looks of this but I love that it exists, and others like it. With true racing cars ever more stifled by restrictive rules there'll be more cars like these with the freedom to express themselves. A modern day Formula Libre.
