The radical Senna is going racing in 2019!

LISTEN 07:17

It’s been only three months since McLaren unveiled the Senna as a successor to the P1, and the British firm has already confirmed that it will build a GTR version of the supercar. The announcement was made at the 2018 Geneva Motor Show, where McLaren also unveiled a concept version of the upcoming track car. Called the Senna GTR, it follows in the footsteps of the P1 GTR as a track-only vehicle built in very limited numbers.

The GTR was unveiled only a couple of months after McLaren chief Mike Flewitt said that the firm wants to race the Senna at Le Mans. This version of the GTR won’t be able to do that due to existing FIA regulations and the fact that it’s being designed as a customer car, but McLaren will use the lessons it learns from this model to develop a proper Le Mans entry. But, before that happens in 2020, the production version of this concept car will arrive in 2019. Let’s find out more about it in the review below.

Despite being labeled a concept car, the Senna GTR looks ready to go into production

Despite being labeled a concept car, the Senna GTR looks ready to go into production. The new features that set it apart from the regular model are by no means exaggerated and look quite common for a production race. The front end retains the headlamps and the hood of the standard Senna, but almost all other elements have been altered. McLaren developed new, wider fenders and a big splitter that extends several inches in front of the nose.

The intakes between the splitter and the nose have been enlarged too, giving the impression that the latter floats in the air. The new fenders now extend more toward the front, almost covering the LED DRLs. They also sport big winglets that improve airflow around the car.

The profile sees dramatic changes too. Not only the fenders are wider to accommodate the wider track, McLaren also revised the side skirts, which are also wider and sharper. The side mirrors are also new, as are the fuel caps in the quarter windows. The standard wheels were replaced by lighter, motorsport-spec units wrapped in Pirelli P-Zero tires.

Out back, there's a new, massive diffuser that extends further away from the body

Around back, it appears as if McLaren kept the standard carbon-fiber wing, but made modifications to the upper fenders and the engine hood. But the biggest change by far lies below the fascia, in the form of a massive diffuser that extends further back. This thing looks like it’s totally independent from the car and it helps the Senna generate incredible downforce. According to McLaren, the production model will be able to generate up to 1,000 kg. That’s a whopping 2,204 pounds!

Another big change is that the new body parts have been designed as clip-on elements to the cockpit structure, which allows for relatively easy modification and replacement. While these cars won’t become professional racers, the fact that they will be raced at private events makes the clip-on standard a good thing. The ability to replace damaged parts as quick as possible is obligatory.

Will feature that central driver layout...
based on the McLaren F1
The Senna GTR will have a more radical, race-oriented cockpit than its standard sibling

McLaren didn’t publish any photos of the interior, but it’s safe to assume that it will follow in the footsteps of the P1 GTR, which had a more radical, race-oriented cockpit than its standard sibling. Look for the dashboard to retain the shape of the production model, but don’t expect it to still feature the vertical infotainment display in the center or the rotating instrument cluster.

The steering wheel will also be replaced with a controller-type unit with many buttons and knobs. The instrument cluster will be replaced by a simpler screen that will display only critical information such as revs, speed, acceleration, tire pressure, and other data you need on the race track.

The floors and the door panels will be stripped off to bare carbon-fiber, while the already sporty seats will be replaced with even more aggressive carbon-fiber units with FIA-approved racing harnesses. All told, the Senna GTR will look like a full-fledged LMP1 prototype inside the cabin.

McLaren Senna GTR Concept Drivetrain

  • Beefed-up 4.0-liter V-8
  • At least 814 horsepower
  • Quicker than standard model
  • 0-to-60 mph in 2.6 seconds?
  • Race-spec transmission
  • Upgraded suspension

Output will increase to "at least" 814 horsepower

Just like the P1 GTR, the Senna GTR will get a few extras under the hood as well. Final specs aren’t yet available, but McLaren confirmed that the new race-spec model will be powered by a beefed-up version of the Senna’s twin-turbo, 4.0-liter V-8 engine. The mill is rated at 789 horsepower and 590 pound-feet in standard spec and McLaren says that output will increase to "at least" 814 horses. No word on extra torque, but the Senna GTR could get more than 600 pound-feet with the upgrades.

Curb weight will remain mostly unchanged, so it’s natural to assume that the GTR, which already benefits from more grip and downforce, will be quicker than the regular Senna in a straight line and will post quicker lap times. While the Senna needs 2.7 seconds to hit 60 mph from a standing start, the Senna GTR could reach this benchmark in 2.6 clicks. Top speed will probably remain the same at 211 mph.

The incredible downforce and the slick tires, combined with the race-spec transmission and revised double wishbone suspension will ensure that the Senna GTR will also post the quickest lap times of any McLaren except for the company’s Formula One cars.

The Senna GTR’s arrival only three months behind the standard model is far from surprising. While the GTR versions of the F1 and P1 took some time to develop, things are moving significantly quicker in 2018 and McLaren is acting accordingly. Sure, the new GTR won’t be here in production form until 2019, but McLaren wants to create as much hype as possible and get interested customers to empty their bank accounts. With production capped to only 75 units, the Senna GTR will probably be sold out in just a few months.

Press release

McLaren Automotive, the British creator of luxury sportscars and supercars, is to offer a track-only version of the new Ultimate Series McLaren Senna, to be called the McLaren Senna GTR.

Unveiling the McLaren Senna GTR Concept today (March 6, 2018) at the Geneva International Motor Show, McLaren Automotive CEO, Mike Flewitt, confirmed that up to 75 examples of the most extreme McLaren car ever will be hand-assembled in Woking, England, during 2019.

“Excelling on the track underpins the heritage of the McLaren brand and is as important and relevant today as it has ever been,” explained Mike Flewitt. “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.”

Expressions of interest will be taken at the Geneva Show and thereafter, with exact technical details of the McLaren Senna GTR confirmed later this year. Based around the same carbon fibre Monocage III structure as the McLaren Senna to ensure the core strength and rigidity needed for a top-flight track car, the McLaren Senna GTR will be similar in weight to the 1,198kg lightest dry total of the road-legal McLaren Senna. With more power and greater torque from the 4.0-litre twin-turbocharged V8 engine than the 800PS and 800Nm developed in the road car – horsepower will increase to at least 825PS – the car will be faster than the ‘standard’ model in a straight line. The additional benefit of a race-style transmission, revised double wishbone suspension and Pirelli slick tyres – together with up to 1,000kg of downforce – will ensure that the McLaren Senna GTR will also post the quickest McLaren circuit lap times outside Formula 1.

The ‘form follows function’ McLaren design philosophy that is at is strongest in the McLaren Senna provides – quite literally – the ideal platform for the McLaren Senna GTR. The car will have a wider track and new fenders front and rear, the changes to the carbon fibre body simplified by the fact that the fenders and other aerodynamic components have been designed as ‘clipped on’ to the cockpit structure, allowing relatively easy modification. The McLaren Senna GTR will also feature a new wheel design, developed specifically for circuit use.

The front splitter of the McLaren GTR Concept is larger than the road-car component and contributes to improved front aerodynamic performance, as does the rear diffuser which is both larger and extends further back. The rear deck is the lowest of any McLaren and aids both aerodynamic performance and cooling, as well as helping to optimise the performance of the active rear wing.

The design of the doors benefits aerodynamic efficiency, the outer skin being ‘pushed in’ as far as possible towards the centre of the car to better channel airflow. Unlike the road-legal McLaren Senna, the McLaren Senna GTR will feature a polycarbonate ‘ticket’ window.

“The McLaren Senna was designed from the outset with the full spectrum of road and track requirements in mind, so developing a GTR version is within the scope of the original project,” explained McLaren Automotive Design Engineering Director, Dan Parry-Williams. “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.”

McLaren Automotive is increasing its focus on providing customers with track-based driving experiences across its full range of cars. A single-make race series has been launched as part of the programme of Pure McLaren track events, allowing McLaren owners with the minimum of an International D-grade licence to take advantage of a full ‘arrive and drive’ package to race in a 570S GT4 car. To support this and other motorsport activities, a network of McLaren retailers specialising in selling and fettling McLaren’s motorsport models has been established; initially 10 in number, the retailers serve Europe, North America and Asia Pacific.
