McLaren’s P1 GTR has been designed strictly with track use in mind but some owners may soon be able to drive their cars on public streets thanks to plans to develop a road-legal version. In case you’ve forgotten, the P1 GTR features a more powerful, 986-horsepower version of the regular P1’s hybrid drivetrain as well as a wider body, more extreme suspension settings and some extensive weight-saving mods.

But it’s not McLaren that is developing the P1 GTR road car but rather fellow British firm Lanzante. The motorsport and engineering firm is the same group behind the McLaren F1’s original 1995 24 Hours of Le Mans victory and since then it’s served as a service center for both road and race McLarens. Now, in an interview with Autocar, Lanzante’s Dean Lanzante has revealed details about the P1 GTR road car project.

More than 40 P1 GTRs have been sold, all of them to existing P1 customers only, and according to Lanzante the modifications required to turn one of these into a road car will vary from car to car depending on where the owner wants to use it.

"We will be tackling all conversions on a case-by-case basis," Lanzante said. "What we do will depend on where the customer wants to run the car and what the regulations are in that region.”

Crucially, Lanzante explained that his company will ensure that the performance of the P1 GTR road car will still be a level above that of the regular P1, meaning it will still be “lighter, have more power, better aero and so on."

Work on the first conversion will begin later this year. Although McLaren is not involved, the project has the firm’s blessing. The result will mean owners will be able to drive out to their track of choice, have fun pushing their cars to the limit, and then head back home, all without the need for a trailer.

The 2015 Goodwood Festival of Speed gets underway today in the U.K., and one of the stars of the show will be this unique McLaren P1 prepared by the MSO personalization department. Its special livery was inspired by motorsport legend Alain Prost, in particular the Frenchman’s patriotic livery worn on his helmet, and all the surfaces were color-matched to the original famous design.

He may have his detractors but there’s no denying that Prost is one of the most accomplished race car drivers of all time and remains a motorsports figurehead even after all these years. He earned four Formula One World Championships, racked up during the 1980s and ‘90s, and three of those were secured during his time with McLaren. Prost has a total of 51 grand prix wins under his belt, which is second only to Michael Schumacher.

Just when it seems things can’t get any better for the 40 individuals taking part in McLaren’s P1 GTR driver development program, the British firm has just confirmed that one of the program’s instructors will be none other than Bruno Senna, the nephew of Formula One legend Ayrton Senna and a former Formula One driver himself.

In case you’ve forgotten, the P1 GTR, offered exclusively to existing P1 owners, comes with membership in a bespoke driver development program that includes specialist driver training, access to the McLaren racing simulator, and maintenanceand transport for the cars. And coaching the members along the way will be instructors with years of racing experience, one of which is Senna.

Much of the training will be handled at special track day events held at race tracks all over the globe. For the inaugural year, there are nine such events: Circuit de Catalunya (Spain), Sepang International Circuit (Malaysia), Circuit of the Americas (United States), Silverstone (United Kingdom), Autodromo Nazionale Monza (Italy), Red Bull Ring (Austria), Spa Francorchamps (Belgium), Bahrain International Circuit (Bahrain) and Yas Marina (Abu Dhabi).

The P1 GTR is a track-only version of the P1 supercar. It has a peak output of 986 horsepower, up 83 hp on the road car, and it also benefits from lighter weight, a wider track and more downforce. The first customer examples are being delivered now, so it won’t be long until the driver development program gets underway.

The lucky few owners of the extreme McLaren P1 GTR have just enjoyed their first track day driving experience with the cars as part of an official driver development program hosted by McLaren. The program, which includes ex-Formula One driver Bruno Senna as one of its instructors, got underway recently at Barcelona’s Circuit de Catalunya, home of the Formula One Spanish Grand Prix, and saw seven P1 GTRowners take part.

It incorporates specialist driver training, access to the McLaren racing simulator, and maintenance and transport for the cars. It also includes nine track day events like the one at Barcelona. The others will also be held at F1-spec tracks including the likes of Malaysia’s Sepang International Circuit, the legendary Silverstone Circuit in the United Kingdom and even a stop at the Circuit of the Americas in Austin, Texas.

According to McLaren chief tester Chris Goodwin, this first round of the program was to give the drivers a taste of what the P1 GTR can really do when fully unleashed. And already the training received by drivers is proving quite effective: two of them were said to have posted competitive lap times after Senna set a benchmark lap time to work towards.

In case you’ve forgotten, the P1 GTR is a track-only version of the P1 supercar. It has a peak output of 986 horsepower, up 83 hp on the road car, and it also benefits from lighter weight, a wider track and more downforce. Build slots, of which there are thought to be no more than 40, were offered exclusively to existing P1 owners and all are sold out.

It may have taken a little more than two years but McLaren has finally built its final P1. Production of the 375th and final car has just been completed, bringing the curtain down on one of the most advanced and dynamically accomplished supercars ever made.

It was at the 2012 Paris Auto Show that McLaren first rolled out the P1, which back then will still in the concept stage. The production version followed roughly six months later at the 2013 Geneva Motor Show and shortly after all 375 build slots were sold out.

After production of a series of prototypes and pre-production models was completed in the summer of 2013, work on the first customer P1 commenced. Running at full capacity, the special production line set up for the Ultimate Series cars and other bespoke projects managed to churn out one finished car per day, with each individual model taking 17 days to complete on average.

The final car was finished in a unique pearlescent orange, achieved through a special tinting process. The color echoes the shade of the 64th and final McLaren F1 road car, chassis #75. It features subtle styling elements in raw carbon fiber weave, with the finish only visible externally on the splitter, diffuser and the aerodynamic blades along the lower body, while the wheels are finished in silver.

Note, while P1 production may be at an end, the car’s more hardcore cousin, the P1 GTR, is still in production, though McLaren expects the last of these to be built in the coming weeks.

As for what comes next for McLaren’s Ultimate Series, CEO Mike Flewitt had this to say: “The McLaren P1 has already established itself as an icon and any car that is to continue the lineage of the Ultimate Series will need to be a worthy successor—a significant step change in technology or performance is required to ensure this is the case. The future is undecided at this stage, which is an exciting proposition.
