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.

GM and Ford quarterly sales continue to slump in China

BEIJING — General Motors and Ford announced their quarterly sales in China fell, albeit at a slower pace sequentially, as the U.S. automakers were hit by a slowing economy amid the Sino-U.S. trade war. GM's vehicle sales in China for the quarter ended June 30 dropped 12.2%, while Ford's sales slumped by 21.7%. While GM also suffered from heightened competition in its key mid-priced SUV segment, Ford was hurt by the limited new models for customers to choose from. For the first quarter of this year, Ford's sales in China tumbled 35.8 percent while GM's skid 17.5 percent. Still, the numbers from GM, the second biggest international automaker in China by sales, and Ford portend more uncertainty for the industry which is trying to rebound from a downward spiral that led to its first annual sales decline last year in more than two decades. GM delivered 1.57 million vehicles in China in the January-June period this year, while Ford delivered 290,321 vehicles. China's factory activity shrank more than expected in June, highlighting the need for more economic stimulus amid higher U.S. tariffs and weaker domestic demand. Annual car sales in China fell last year for the first time since the 1990s, and they are expected to fall this year too. Sales tumbled 16.4% in May from the same month a year prior, the China Association of Automobile Manufacturers (CAAM) said. That marked the 11th consecutive month of decline and followed falls of 14.6% in April and 5.2% in March. U.S. car companies' share of total China passenger vehicles sales fell to 9.6% in the first five months of this year from 10.9% in the year-ago period, according to CAAM. Over the same period, German car makers' share has risen to 23.3% from 20.9% and Japanese auto makers' to 21.3% from 17.3%. CAAM is set to announce June sales next week, which industry analysts forecast will be negative.   New models In China, GM has a joint venture with SAIC Motor Corp, in which the Buick, Chevrolet and Cadillac are made. It also has another venture, with SAIC and GuangxiAutomobile Group, in which they make no-frills minivans and have started to make higher-end cars. Sales of GM's affordable brand Baojun dropped 31.8% for the latest quarter. But luxury brand Cadillac's sales jumped 36.6%. GM sold 3.64 million units in China last year, down from 4.04 units in 2017. Ford makes cars in China through its joint venture with Chongqing Changan Automobile Co and Jiangling Motors Corp (JMC).

Watch the National Corvette Museum sinkhole being filled in by R/C cars

Okay, so not exactly cars, but Bobcats - but still quite cool. You might remember that the National Corvette Museum had that little divot that needed to be filled in. Turns out the construction firm of Scott, Murphy & Daniel doing the work is using two remote-controlled Bobcats to fill the sinkhole with "manufactured sand," which in this case is crushed limestone. It appears that the Bobcat company has offered remote operation since at least 2007 via a wireless transmitter that works up to 1,500 feet away. So yes, that means two SMD employees stand on the edge of the pit and flick joystick levers for hours at a time, one in charge of a Bobcat with a roller-compactor attachment, the other in charge of a Bobcat with a bucket. And that, to us, is a pretty good way to earn the daily bread. Check out the video above for the latest sinkhole update.
