Porsche hybrids come up short at Le Mans

Two cars, one finish, zero victories. That's a brief synopsis of Porsche's hybrid-vehicle performance in the 24 Hours of Le Mans race in France. There's always next year. Porsche entered two 919 Hybrid vehicles in the race. The No. 14 car essentially limped to the finish line after encountering drivetrain problems. The other Porsche hybrid, No. 20, was driven by Germany's Timo Bernhard, New Zealand's Brendon Hartley and Australia's Mark Webber. That car ran for more than 22 hours before its own powertrain issues did that racing team in for good. Both vehicles ran towards the front of the pack at times during the race, and the No. 20 car actually led the race after about 20 hours. Still, both teams said they were disappointed in the results. Porsche sister company Audi came up big for the 13th time in the race's long and storied history. One Audi R18 E-Tron Quattro won the race, while another finished second. The Toyota that had pole-position and was winning much of the race shut down after 15 hours of racing because of electrical issues and Nissan had trouble with is ZEOD RC. Check out Porsche's press release below, and read here for a more general race recap. STRONG PERFORMANCE BY PORSCHE 919 HYBRIDS BUT NO DREAM ENDING IN PROTOTYPE RETURN TO LE MANS Le Mans. After a strong performance by both Porsche 919 Hybrids, the Porsche Team was left empty-handed after a dramatic final stage of the race. Following more than 22 hours, car No. 20 driven by Timo Bernhard (Germany), Brendon Hartley (New Zealand) and Mark Webber (Australia) suffered a powertrain problem at the world's most famous endurance race, the 24 Hours of Le Mans. Earlier in the race the LMP1 class car was leading overall for a significant period of time. The second innovative and highly complex prototype – in the hands of Romain Dumas (France), Neel Jani (Switzerland) and Marc Lieb (Germany) – likewise proved to be very competitive, but was hampered by a drivetrain problem. However, their No. 14 car crossed the finish line under its own power. After a thrilling start to the race with changing weather conditions, numerous accidents and a relatively calm night, Bernhard took the overall lead in the No. 20. The longtime Porsche factory driver returned to the top spot after 20 of the 24 hours. At 12:36 (CET) on Sunday, he handed the leading car over to Webber. Less than 20 minutes later the Australian was forced to slow down and drove solely on electric power back to pit lane.

Jay Leno puts carbon fiber wheels to the test on a Porsche 911 GT3 RS

Jay Leno's Garage usually focuses on looking at cars new and old, speaking to their owners and then Jay taking a drive to see what he thinks. However, Leno throws his usual shtick to the curb this week to do a full product test of the carbon fiber wheels from a company called Carbon Revolution. If you're not interested in hearing about wheels for 18 minutes, don't worry. They get mounted on a Porsche and are tested back-to-back with stock wheels, and Leno takes the 911 for a track test, too.
While carbon-fiber wheels aren't exactly a new idea, Carbon Revolution's goal is to create a lightweight, one-piece product that can be mass produced. The company even claims that it already has a deal with an OEM automaker to offer them on a vehicle in a few years. The key to the technology is that it doesn't need an expensive autoclave to be made.
In the meantime, the company's carbon fiber wheels are available as an aftermarket option for about $15,000 a set, according to the video. They weigh in at about 15.5 pounds each and offer OEM-levels of stiffness, so they could cut some unsprung mass off of a performance car. Watch here as Jay and his mechanic Bernard lap Willow Springs and give their feedback about what they think of this cutting-edge technology.

Porsche 919 Hybrid used 500 gallons of fuel to win Le Mans

After 395 laps and over 3,300 miles covered, Porsche claimed its record seventeenth overall win at the 24 Hours of Le Mans this year. Those, however, were only a few of the numbers that went into the German team's landmark campaign, the fourth one-two victory in the history of its assault on the endurance race. And now it has released some of the other mind-boggling figures behind its win. Over the course of 24 grueling hours of competition, the winning Porsche 919 Hybrid averaged a staggering 139 miles per hour, reaching a top speed of over 211 mph. Along the way, the winning car changed gears over 25,000 times. We can imagine the drivers worked up quite a sweat in a cockpit, whose temperature topped 80 degrees, with less than a quart of water to drink during each stint between pit stops – the longest of which lasted over ten hours. Little wonder that Mark Webber lost over six and a half pounds by the end of the ordeal. Naturally, pit stops played a huge part in the campaign, and the team – whose headcount topped 120 – carried out 90 stops (30 per car) over the course of the race. All told, the three cars went through 116 tires, each car had its oil refilled entirely, and the winning car alone swallowed up 500 gallons of fuel. And that's not even counting the energy recuperated by the electric component of the hybrid powertrain, which would be enough to power a family home for three months. Those are just some of the most notable figures, but they give us a pretty good idea of the enormity of the whole endeavor. Want to read more? There's a whole list of numbers in the press release below. Related Video: The 17th overall victory for Porsche at the Le Mans 24-Hours 395 laps to victory Stuttgart. On Sunday, 14th June 2015, the trio of Earl Bamber (NZ), Nico Hulkenberg (GER) and Nick Tandy (GBR) took the 17th overall victory for Porsche at the Le Mans 24-Hours. They were followed across the line by the sister car of Timo Bernhard (GER), Brendon Hartley (NZ) and Mark Webber (AUS). This made it the fourth one-two result for the brand after achieving this in 1971, 1987 and 1998. But there are more interesting facts and figures about the race. • The winning team completed 395 laps (5,382,82 kilometres). This year's race was only two laps short of the longest distance covered in Le Mans back in 2010. • The average speed of the winning Porsche 919 Hybrid was 224.2 km/h.
