2015 24 Hours of Le Mans live race report

Check back regularly for more race updates every few hours. No, you don't need to stay up for the entire 24 Hours of Le Mans, but if you want to catch any of the action, Autoblog friend Reilly Brennan has a handy guide. And to keep you up to speed on the latest race events, we'll be posting live from Le Mans with regular race reports.Hour 1: Five laps in, Audi breaks up the three Porsches at the front, with the #19 919 Hybrid, driven by Nico Hulkenburg, passed by all three R18s. Hulkenburg eventually took back fifth position only to fall back again after the first pit stop. Meanwhile, clutch trouble kept the #23 Nissan GTR-LM in the pits until 15 minutes into the race. The other two Nissans were forced to start at the back of the grid after failing to the meet the 110 percent qualifying speed regulation. At the end of the first hour, just 7.5 seconds separated the first six cars. Then the factory team #92 Porsche GTE car caught fire, with the the #13 Rebellion P1 car taking frontal damage in the ensuing carnage. With the safety car out, the field is once again bunched up.Hour 2: The slugfest between Audi and Porsche continues, with neither side backing off. Halfway through the second hour the #7 R18 passes both leading Porsches for the top position. After another round of pits stops Porsche regains the lead until lap 30, when the Audi overtake once again and quickly pulls out a three-second gap. Nico Hulkenburg passes the other two Audis to join his Porsche teammates. At the beginning of the third hour it's Audi #7, Porsche #17, #18, and #19, followed by Audi #8 and #9. 33 seconds separates this group, with Toyota a minute back from the front car.Hour 3: On track the action refuses to stop. Although it's early, Audi is looking strong with the overall lead in the #7. What's more is that the Audis run four stints per set of tires, while the Porsche cars have to change rubber every third stop. But after a quick refueling, the lead R18 gets a tire puncture and comes back in 3 laps later, allowing Porsche to take over the top two spots. Then as the hour closes out a yellow flag causes traffic to bunch up and the #8 Audi gets stuck with nowhere to slow down. Driver Loic Duval dives for the side of the road but hits the guard rail and careens across the track, damaging the front and rear bodywork. The rest of the car is still intact, though, and once in the pits Audi replaces the entire front and rear of that in only three minutes.

100-year-old Yellowstone ranger station now powered by Camry Hybrid batteries [w/video]

With a new project, Toyota is bringing power to the prairie and finding a way to reuse nickel-metal hydride batteries at the same time. The automaker recently completed assisting Yellowstone National Park's installation of a solar power station at the Lamar Buffalo Ranch to electrify the ranger station and education center there for the first time. Toyota's major part in the system is an array of 208 batteries that are repurposed from old Camry Hybrid sedans, and they can store 85 kilowatt-hours of energy at a time. That's as much as one 85-kWh battery pack from one top-of-the-line Tesla Model S. Toyota figures that the whole setup should generate enough annual electricity for six average US homes, which is plenty for the ranch. For a constant source of power, the site plans to install a micro-hydro turbine in a nearby stream in 2016. Prior to creating the wall of batteries to store all of this energy, Toyota disassembled and tested each one. It also installed a new management system on them to maximize their lifespan. You can get a better idea of what the whole system looks like in the automaker's video, below. This content is hosted by a third party. To view it, please update your privacy preferences.

Toyota Flips the Switch to Sustainable Power at Yellowstone National Park Lamar Buffalo Ranch Renewable, Zero Emission Energy System Is Now Online System Features 208 Re-used Camry Hybrid Batteries May 12, 2015 Torrance, Calif. (May 12, 2015) – The lights are on where the buffalo roam. At the Lamar Buffalo Ranch field campus in Yellowstone National Park, an innovative distributed energy system that combines solar power generation with re-used Camry Hybrid battery packs is now online. The result: reliable, sustainable, zero emission power to the ranger station and education center for the first time since it was founded in 1907. Announced in June 2014, the partnership among Toyota, Indy Power Systems, Sharp USA SolarWorld, Patriot Solar, National Park Service and Yellowstone Park Foundation is an innovative effort to extend the useful life of hybrid vehicle batteries while providing sustainable power generation for one of the most remote, pristine areas in the United States. Solar panels generate the renewable electricity stored within the 208 used Camry Hybrid nickel-metal hydride battery packs, recovered from Toyota dealers across the United States.

Toyota engineer warns automous cars could increase fuel use, urban sprawl

An increasing number of people are starting to consider the potential downsides of a transition to autonomous cars. The FBI is already looking at them for the potential ill effects on law enforcement, and a scientist for Toyota is raising the possibility that driverless vehicles could actually be detrimental to the environment over the long term.
Ken Laberteaux, who studies future transportation for Toyota, thinks that autonomous cars could lead to more pollution, not less, says Bloomberg. However, Laberteaux's theory isn't so much based purely on science as it is considering behavioral and historical trends. "US history shows that anytime you make driving easier, there seems to be this inexhaustible desire to live further from things," said Laberteaux during a presentation at the Automated Vehicles Symposium in San Francisco, CA, cited by Bloomberg.
Laberteaux's belief is that if commuters can make their drives easier, then they will be more willing to live farther away from the cities where they work. The end result would be more urban sprawl and increased pollution from the longer travel times.
