McLaren P1 GTR looks ready to hit the track [w/video]

McLaren may be first and foremost a racing constructor, but it's been known to make a few road-going supercars now and then. This, though, is something in between. It's the new McLaren P1 GTR, and it's just made its live debut on the floor of the Geneva Motor Show. In case you missed our earlier coverage upon its release, or the subsequent video of it hitting the track, allow us to reiterate: It's based on the P1 – McLaren's million-dollar hybrid hypercar – but it's tuned specifically for the track. Not for racing and not for driving on public roads – like the Ferrari FXX K or the Aston Martin Vulcan we'll be bringing you shortly as well, the P1 GTR was made specifically so that wealthy enthusiasts would have a toy to play with on closed circuits. To prep it for track duty, the engineers in Woking upped the output from the 3.8-liter twin-turbo V8 hybrid powertrain from 903 horsepower (as if that wasn't enough) to 986. They ditched 110 pound of excess weight. They fitted racing slicks, dropped the suspension and tweaked the aero package. The result, as you can see from the live images in the slideshow above and the video below, is pretty badass – even if you don't dig the throwback Harrods yellow and green livery.

McLaren shoehorned the F1's V12 into a BMW M5 wagon test mule

Automakers are known to utilize preexisting vehicles as test beds for major research and development purposes. But some of the zombie mashups produced in-house can result in pretty interesting combinations. Case in point, when McLaren was developing its BMW-sourced naturally-aspirated 6.1-liter V12 for the legendary F1, the company put the engine in … a BMW M5 wagon? Yup, you read that correctly. ItÂ’s no mystery that the legendary F1 came with a BMW-sourced V12. That "M70" V12 originated from its placement in the E32 7 Series and E31 8 Series “50” models in the 1980s up through the 1990s. The version that went into the F1, however, is more closely related to the M-tuned "S70" V12 found in the E31 850CSI, which was the pseudo M-variant to the 8 Series that wasnÂ’t officially designated an M model. But it did feature full-fledged tuning from the M Division. On "Top Gear" presenter Chris HarrisÂ’ podcast, "Collecting Cars", Harris interviewed David Clark, the former director of McLarenÂ’s cars for both the road and motorsports between 1994 and 1998. Clark revealed that they took an E34 BMW M5 wagon and shoehorned the S70 V12 into its engine bay as the mule for testing the F1Â’s engine. Clark even said he drove the car himself as they were fine-tuning the V12Â’s engine output. YouÂ’re probably wondering, how the heck did that thing fit? But it isnÂ’t that surprising. The E34 5-Series was designed to house either the BMWÂ’s venerable straight-six or the new-at-the-time V8. And there was room enough to house the V12 as well, particularly since BMWÂ’s V12 was essentially two of its “M20” straight-sixes bolted together at the crank in a vee. When Clark was testing the S70 V12 in the wagon, he and his team ended up with the 627 horsepower and 479 pound-feet of torque the F1 became known for. ThatÂ’s nearly twice the power the production M5's 311 hp and 266 lb-ft at the time. Clark also divulged that the actual prototype mule still exists, but itÂ’s in BMWÂ’s secret collection of prototypes, and itÂ’s never been revealed to the public. He does, however, hope that one day, BMW will open its doors and show off the incredible mashup of an automobile. Until then, youÂ’ll have to rely on the few custom engine swaps done by owners to get a taste of what a V12-powered E34 M5 is like. Rumor also has it that McLaren could be working on a new direct F1 successor with help once again from Gordon Murray.

See the evolution of McLaren F1 cars in one GIF

If you dig racecars and history, you'll enjoy the .gif file on display below. It comes to us from the folks at automotive parts website PartCatalog.com, and it shows how McLaren's Formula 1 cars have changed from the very first one to this season's black and orange Honda-powered machine. And they have certainly changed. That very first car had scarcely an aerodynamic aid to the radically winged racer of today.It's also interesting to see how driver positioning has changed over the years. Through the '70s and '80s, the driver was pushed farther and farther to the front. Then in the '90s and '00s, the driver started to be pushed back to the middle, and longer noses became common.

It also features some of the most famous F1 cars of all time. Fans of vintage F1 racing and of the film Rush may recognize the McLaren M23 James Hunt piloted to a championship victory over rival Nicki Lauda in 1976. There's also the 1985 McLaren MP4/2B that was the last McLaren Nicki Lauda would drive, and the car that would take Alain Prost to a championship. Prost's rival Ayrton Senna also has a car in this .gif, and that's the 1988 Honda-powered car he drove to his first ever championship. There are many other cars in this .gif we don't have time to cover though, but you can learn more about them and the cars we mentioned by checking out McLaren's great history page. Each car there has a brief profile covering the stats, and lengthier articles with more background. It's a great way to spend a morning. Related Video:
