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.

Star Wars Car Drives To The Dark Side Of Comic Con

When it comes to designing coveted collectible toys for sale at Comic-Con, the annual celebration of pop culture lifting off Thursday in San Diego, the sky's the limit for the designers at Mattel. Fittingly, the building where Mattel's dreamers conceive of their limited-edition playthings is just down the street from the Los Angeles International Airport. Inside the colorful design center - a Hot Wheels-themed shuttle bus transports employees from Mattel's parking garage - the designers have spent the past year working on 10 toys created especially for the Comic-Con crowd, including a replica of the Batmobile from the upcoming game "Batman: Arkham Knight" and a 9-inch-tall action figure of Superman killer Doomsday. "We don't have to worry about retail. We don't have to worry about margins," said Doug Wadleigh, Mattel's senior vice president of global brand marketing for boys and entertainment. "We don't have to worry about operational efficiencies. We only have to worry about creating the coolest toys for our fans. Period." It also offers some escape from Mattel's reality these days. Like other toy makers struggling in this digital, video-centric age, the company is trying to remain relevant in the retail world. Core brands like Barbie have seen less of a demand, with a 14 percent drop in sales in the first quarter of this year. Mattel had a net loss for the first three months ending March 31 that totaled $11.2 million. But things will at least seem rosier at Comic-Con, where eager buyers for the toys await (the only other place they will be sold is on the Mattel collector's site). Mattel's exclusives this year run between $20 and $85, but elite toys can fetch much more when they're put up for auction. The crown jewel for Wadleigh and his team this year is a Darth Vader die-cast car, the first official collaboration from Hot Wheels and the "Star Wars" franchise. The car - imagine if a Chevrolet Corvette C5 and the villainous Sith lord's helmet had a baby - comes in a sleek black box and encased in a replica of Vader's lightsaber, complete with a swooshing sound effect. "We've been trying to partner with Lucasfilm and Disney on this property for a long time," said Wadleigh. A full-size working replica of the Vadermobile will be on display at Mattel's booth at the massive San Diego Convention Center.

GM under fire from safety advocates over braking problem caused by recall fix

Safety experts are lambasting General Motors over what they say is the automaker’s slow notification of owners of certain 2019 sedans and trucks that a recall fix could cause power braking to fail and increase the risk of a crash, the Detroit Free Press reports.  GMÂ’s original recall in December targeted about 550,000 Cadillac CT6 sedans and Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, all from the 2019 model year, over potentially defective electronic stability control and antilock brakes. In that case, GM said the errors would not show up as a diagnostic warning on the instrument cluster. But after GM had done recall work on 162,000 vehicles, about 1,700 owner have complained that their power brakes didnÂ’t work after they had the recall done and then used the OnStar app to start their vehicle. GM then issued a supplemental fix for customers whoÂ’d already had their vehicles serviced. In this case, a diagnostic warning should illuminate saying either “Service Brake Assist” or “Service ECS,” which GM says is a signal that a customer should not drive the vehicle and instead call their dealer, which will tow the vehicle and have it repaired. Safety advocates say the automaker hasnÂ’t gone far enough to protect customers. “The fact that you could potentially start a vehicle and not have brakes is a pretty risky proposition,” Sean Kane, president of the Safety Research and Strategies, which works on auto issues for plaintiffs and governmental organizations, told the Freep. “The fact that they wouldnÂ’t notify owners (sooner) is pretty stunning.” GM told the Freep it was required to notify the National Highway Traffic Safety Administration and file paperwork before it notified customers about the original recall, which was made Dec. 12. It then had to investigate and resolve the problem created by its original recall fix before alerting customers. GMÂ’s call center and dealers are contacting the remaining 900 customers who havenÂ’t yet had the update made to the original recall repair. GM also hired a vendor to send recall letters to the 550,000 customers affected by the original recall notifying them about the update. There are no known injuries or deaths related to the problem.
