McLaren preparing 650S extreme track-bound versions

McLaren isn't a company used to standing still. It has 182 grand prix victories under its belt, a dozen Formula One titles and some of the most lust-worthy supercars ever made. So we could hardly blame anyone (ourselves included) for impatiently anticipating what the team at Woking has coming next. Of course, McLaren itself is eager to keep its customers focused on the considerable offerings it already has on hand, but speaking to a few key McLaren personalities has given us some clues. The project known internally as P13 is focusing on a rival to the Porsche 911 Turbo and Audi R8. P14 is still a mystery that no one at Woking is willing to talk about at this stage. And P15 is set to slot in between the 650S and P1 once the latter completes its 375-unit production run. But let's not get too caught up with upcoming products before we're done with the latest 650S. As our own Matt Davis will be bringing you shortly in our First Drive report, McLaren has been demonstrating the new 650S to journalists as a prodigious track weapon at the Ascari Race Resort in Spain. But before all is said and done, there will be even more track-focused versions of the 650S to follow. Speaking one-on-one with Autoblog, McLaren CEO Mike Flewitt confirmed that the new 650S is destined for the racetrack, and in multiple guises at that. First up will be the 650S GT Sprint, which could very well get a different name before it hits the circuit. This track-bound version of the 650S will follow in the footsteps of the 12C GT Sprint, a circuit toy of which McLaren has sold about 25 examples to date. Developed by McLaren's GT racing department, the 12C GT Sprint features updated aerodynamics, suspension and safety equipment, along with a set of Pirelli racing slicks to better suit it for roadcourse use. We'd expect the 650S GT Sprint (or whatever it's ultimately called) to carry over most (if not all) of the same features, plus the upgrades which McLaren Automotive applied to the 12C to transform it into the 650S – including the revised front end and upgraded engine. Flewitt tells us to expect the new Sprint track car to launch later this year. McLaren CEO Mike Flewitt tells us to expect the 650S GT Sprint track car to launch later this year. It won't be until next season, however, that McLaren GT will hit the racing circuit with its new 650S GT3.

McLaren reveals new P1 GTR ready for gentleman racers

There are race cars and there are road cars. McLaren is known for making both, but lately there's been a new class of vehicles emerging in between. They're supercars developed specifically for the track but for no specific racing series, and the new McLaren P1 GTR is the latest. Previewed in concept form in Monterey this past summer, the P1 GTR is now ready to hit the track. It's based, of course, on the P1 – Woking's million-dollar flagship hybrid hypercar – but incorporates a long list of upgrades to make it better suited towards ripping around a closed circuit than an open road. For starters, the 3.8-liter twin-turbo V8 hybrid powertrain has been optimized for track use and retuned: the internal combustion engine cranking out 789 horsepower (up from 727) and the electric motor another 197 (up from 176) for a combined output of 986 hp. The other side of the power-to-weight ratio has also been optimized, with unnecessary elements removed and many parts replaced by lighter ones: The glass roof and engine cover, for example, have been replaced by carbon fiber, and the side windows by plexiglass. There's also a new Inconel and titanium alloy exhaust that saves 14 pounds all by itself. The result of these and other measures is a drop in curb weight by a solid 110 lbs. Of course the performance-obsessed engineers in Woking didn't stop there. They also dropped the suspension by two inches and widened the track by over three, riding on 19-inch alloys with Pirelli slicks. The aero has also been revised, with a splitter jutting out the chin and a fixed wing rising a foot and a half taller than the roof, helping the P1 GTR produce 10 percent more downforce than the road car on which it's based. Hit 150 mph on the straightaway and you'd be generating 1,455 lbs of downforce, assuming you haven't activated the Drag Reduction System flap in the rear wing by then. Although it hasn't disclosed the details, and as good as the road-car's stoppers are, McLaren has hopefully upgraded the brakes as well. Like arch-rival Ferrari's XX client development program (and the path that Aston Martin is tipped to take with the upcoming new Vulcan), the P1 GTR will be part of an organized program. Participating owners will start at the McLaren Technology Centre to have their seats fitted, livery designed and fitness assessed before hitting the first track sessions at Silverstone in the UK and Catalunya in Spain.

Chris Harris brings together the 918 Spyder, LaFerrari, and P1

The Porsche 918 Spyder, Ferrari LaFerrari, and McLaren P1 show that a hybrid powertrain can make for blistering performance despite its electric assist. This trio doesn't arrive on track together very often, but Chris Harris assembled these three stars at the Portimao circuit for a nearly hour-long demonstration of their amazing capabilities. So, which one is quickest around the track? Harris provides an answer with in-car video of all three contenders. His team also goes out of its way to even the playing field by sourcing tires independently from Pirelli for the P1 and LaFerrari. With the technical part out of the way, Harris can start having fun by doing his usual slides during the driving comparison. Tiff Needell and Marino Franchitti also eventually show up to provide the perfect recipe for a track battle in these hypercars. If you don't have the time, skip about 14:25 into the clip just to see the lap times. However, those numbers only tell a tiny part of the story. The whole video is definitely worth a watch.
