24 Hours of Le Mans an on-and-off love affair

There was little usual about this year's 24 Hours of Le Mans - intermittent rain in the weeks before the race meant cars didn't get on track as much as they wanted, and intermittent rain during the race meant cars went off track a lot more than they wanted. The race started with a wet track, and one of the records broken because of the random downpours was the number of times the safety car led the field - 11 times this year - although the record of two hours and 53 minutes of lapping behind the safety car, set in 2011, was not eclipsed.
None of that served to dampen the action. With little more than an hour left in the race there were cars still only a few seconds apart fighting for position, leads still changing because of pit stops and everyone drafting anyone they could.
Things didn't go the usual way up front, either - well, not exactly...

Recharge Wrap-up: Tesla seeks Gigafactory architect, Uber hails carpools

Tesla is looking for an architect to help design its proposed Gigafactory battery manufacturing facility. According to the Palo Alto-based job listing, which is titled "Architect - Gigafactory," the applicant must have, among other qualifications, over five years of experience with "high-tech infrastructure and operational facilities (semiconductor, solar, battery, waste water treatment plants, etc.)." The job also includes being away from home quite a bit, as it the listing states, "This full time role requires the flexibility of traveling when needed (up to 70 percent) and doing whatever it takes to achieve project objectives." Think you've got what it takes? See the listing for yourself, here, or read more at Silicon Valley Business Journal. Tesla has appointed Robyn Denholm of Juniper Networks to its board of directors. Denholm is Executive Vice President, Chief Financial and Operations Officer at Juniper Networks. Denholm replaces Brad Buss as chair of Tesla's Audit Committee and a member of the company's Compensation and Nominating and Corporate Governance committees. Buss will remain a member of Tesla's board as he joins SolarCity as CFO. Denholm is Tesla's first female director. Read more at Bloomberg, or in the press release below. Uber, the company behind the now famous ride-hailing app, is introducing its carpooling service, UberPool. The service matches drivers with (hopefully multiple) passengers going to similar destinations, with users paying just a fraction of the cost of a normal taxi, or even an Uber ride. If a rider can't get matched with a driver, they can enjoy a discounted Uber ride. As the company points out in its blog, "At these price points, Uber really is cost-competitive with owning a car, which is a game-changer for consumers." UberPool is currently running a private beta program, which it plans to expand on August 15. Read more in-depth about the UberPool at Forbes, or learn more at Uber's blog. For a few reasons why this new expansion might run afoul of archaic laws (put there to keep entrenched interests in play), check out Engadget. Plug-in hybrids are encouraging an evolution of transmission technology. Companies like Schaeffler and ZF Friedrichshafen are adapting their transmissions to include electric motors within them for use in plug-in hybrids. For example, the electric motor in ZF's eight-speed powers the transmission when the internal combustion engine is shut off.

Audi reveals all-new R8 ahead of Geneva debut

This year's Geneva Motor Show is shaping up to be an absolutely orgy of supercars, but though there will be many that will surely outperform it, few have been as hotly anticipated as the arrival of the all-new, second-generation Audi R8. And here it is. Based around an all-new Audi Space Frame chassis, the new R8 is constructed of a higher proportion of aluminum and carbon fiber than its predecessor. The result is a frame that weighs 15 percent less at just 441 pounds – yet is 40 percent more torsionally rigid - tipping the scales at 3,205 lbs in top spec. Into the middle of that frame Audi has installed a revised version of its 5.2-liter V10, eschewing turbochargers but incorporating new technologies. While other powertrain options are expected to follow, Ingolstadt has gone straight for the top of the range at launch: the 'base' V10 model kicks out 540 horsepower and 398 pound-feet of torque to reach 62 miles per hour in 3.5 seconds and a top speed of 201 mph. The upgraded V10 Plus, however, turns those figures up to 610 hp and 413 lb-ft to reach 62 in just 3.2 seconds, 124 in under ten and a 205-mph top speed. All the while, Audi has also equipped the new ten-cylinder engine with both direct and indirect injection, stop/start and cylinder deactivation systems to cut fuel consumption by 10 percent. It also boasts dry-sump lubrication and a variable exhaust system. Power is transmitted to the road through a seven-speed dual-clutch transmission, a mechanical diff and a revised Quattro all-wheel drive system that can send 100 percent of available torque to either the front or rear axle. Aluminum wishbones suspend it all on 19-inch wheels (or optional 20s), with available variable steering and carbon ceramic brakes (optional on the V10 and standard on the V10 Plus). Underbody aerodynamics generate more downforce and a more slippery form, aided by a deployable rear spoiler (or a fixed carbon wing on the Plus model). All those tantalizing greasy bits are cloaked in fresh aluminum sheet-metal, riding on a track that's 1.6 inches wider: the whole shebang stretches 14.5 feet long, 6.4 feet wide and 4.1 feet high, riding on an 8.7-foot wheelbase. Among the myriad new technologies developed for the new R8 are the full LED headlights with optional laser high beams (where they're legal, at least, which currently doesn't include these United States).
