Why does the Corvette Stingray have so many vents? Here's why

Just looking at the new 2014 Chevrolet Corvette Stingray, it's not hard to see that the car's design was created with aerodynamics at the forefront, but Chevrolet designers point out exactly what went into designing the iconic coupe in a pair of recently released videos. The videos show the Corvette going through early design phases, including clay models and wind tunnel tests, as well as talking to the car's chief engineer, Tadge Juechter.
Both videos help explain various aspects of the C7 Corvette, but it's the aero tuning of the car that is most interesting. This includes extra attention paid to the lower air dam and vented hood to help reduce drag and lift, while the rear quarter inlets are for differential and transmission cooling. Juechter said that some of these aero-tuned elements were inspired from GM's involvement in racing.
If you have about five minutes and you can't get enough information about the new 'Vette, then check out the videos posted below.

Can DARPA hack into a Chevy Impala through OnStar?

An ex-video game wizard named Dan Kaufman tracked a circuitous route to becoming the head of the Software Innovation Division at the Defense Advanced Research Projects Agency. DARPA normally makes these pages because of its work with autonomous vehicles and automobile technology that overlaps with military applications, but for the past five years Kaufman and his multiple research teams have been working on creating unhackable software code that could be used in military drones. Part of that work has involved hacking into just about everything else, and as a segment on 60 Minutes reveals, that includes cars. The masterminds discovered a way to hack into OnStar, the General Motors telematics system. After figuring out how to hook into OnStar's emergency communication system, they overwhelmed it with data. While the computer was busy trying to manage the overrun of data, the research team inserted code that took control of the sedan's other computers, giving it control. So while reporter Leslie Stahl tooled around in a parking lot, a DARPA researcher with a laptop would occasionally take control of the car, like by applying its brakes or, conversely, removing the ability for Stahl to use the brakes. Hacking into vehicles has been in the news for years: Car and Driver ran a feature on the various ways cars could be hacked in 2011, two hackers released a car-hacking code at the hacker-fest Defcon in 2013 and demonstrated how it worked on a Toyota Prius and Ford Escape, and German researchers demonstrated how they could hack into BMW's Connected Drive remote-services system last week via an attack on the cars' telematics units. This isn't about GM or Onstar or the future; hacking into cars of all kinds isn't coming, it's here, and it doesn't take the half-billion-dollar annual budget of a small DARPA division to do it. Check out the 60 Minutes video on the CBS site (you can watch the entire video from a mobile device without logging in). The OnStar hacking starts at 6:45, but it's worth watching what leads up to that. News Source: Jalopnik Chevrolet Safety Technology Infotainment Autonomous Vehicles Videos Sedan hacking 60 minutes

Porsche wins the 2015 24 Hours of Le Mans

The question going into this year's 24 Hours of Le Mans was whether or not the Porsche 919 Hybrid would be able to combine its qualifying pace with race reliability. After battling neck-and-neck with Audi's R18 for most of the race, the answer is a resounding yes. Not only did Porsche drivers climb the first two spots on the podium, they did so without any major mishaps on track. This win is the first overall trophy for Porsche since 1998. Audi previously won the last five races, and 13 of the last 15. Corvette also returned to the winner's circle, with the No. 64 C7.R taking winning the GTE Pro division. The victory is the first class win for Corvette since 2011. KCMG won the LMP2 class in ninth overall. With 45 minutes to go the No. 98 Aston Martin crashed out of first place in GTE Amateur, giving the class win to SMP Racing's Ferrari and second place to the Patrick Dempsey Racing Porsche 911 RSR. For the full list of official results, click here. The GTE Pro class proved to be just as exciting as the P1 class, with a four-way battle for first after four hours into the race. For most of the race, the battle at the top went back and forth between the two German manufacturers. An tire puncture in the No. 7 Audi gave up the lead to Porsche, and moments later a crash forced the No. 8 into the garage. But a three-minute replacement of the front and rear bodywork kept the Audi in contention. As the race wore into the night, Porsche maintained a slightly faster pace than Audi. Nick Tandy took the lead on Lap 253 early Sunday morning, and car No. 19 never gave up the top position. The win is the first for all three drivers of the No. 19 – Nico Hulkenberg, Earl Bamber, and Nick Tandy. A lap behind in second was the No. 17 Porsche. The Audis fought reliability problems late in the race but still finished third with the No. 7 R18. The GTE Pro class proved to be just as exciting as the P1 class, with a four-way battle for first after four hours into the race. As the Aston Martin cars dropped away, the lone Corvette Racing entry took over, followed by a charging AF Corse team Ferrari 458 Italia. The Corvette and Ferrari continued to trade places in the final hours until gearbox trouble forced the No. 51 Ferrari out of contention. It was eventually passed by the other AF Corse car, No. 71. Nissan experienced all the pain of a first-year effort with its front-wheel-drive GT-R LM Nismo.
