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 to idle car production at five factories as Americans continue CUV love affair

In case you needed another reminder that Americans have fallen out of love with sedans, General Motors today announced plans to idle five factories in January in a bid to cut its inventory to 70 days. Detroit-Hamtramck Assembly ( Buick LaCrosse, Cadillac CT6, Chevrolet Volt and Impala) and Fairfax Assembly in Kansas ( Chevy Malibu) will stop production for three weeks. Lansing Grand River ( Cadillac ATS and CTS, and Chevy Camaro) is going down for two weeks, while Lordstown, OH ( Chevy Cruze) and Bowling Green, KY ( Chevy Corvette) will go idle for a week each, Automotive News reports. GM's shutdown reflects a broader problem with the company's supply – at 847,000 vehicles, the company's supply increased unsteadily from a low of 629,000 units in January of 2016. That's more than a 25 percent increase in the past year. Citing information from Autodata, The Detroit News reports that at the end of November, GM had a 168-day supply of LaCrosses, 177 days' worth of Camaro, 170 days of Corvette, 121 days for Cruze, 119 days for ATS, 132 days for CTS, and 110 days of CT6. Meanwhile, inventory of the company's more popular vehicles is actually below the professionally accepted 60- to 70-day supply, The News reports. The Trax, Colorado pickup, and GM's full-size SUVs are sitting below 50 days and experiencing year-over-year sales increases. GM needs a rethink of its inventory levels, which is something that's apparently coming. "We're going to be responsible in managing our inventory levels," GM spokesman Jim Cain told The News. Another unnamed spokesman told Automotive News the company's day-to-day supplies would "fluctuate before moderating at year-end." But at least one analyst thinks this won't be the last time Detroit needs to stop production to level things out. "Incentives are elevated, residuals are declining, and rates are rising," Brian Johnson, an analyst with Barclays, told The News. "And while GM in particular may benefit in the months ahead from new product launches, it's important to recognize that GM's inventory is elevated at the moment, and it wouldn't surprise us if they need to announce another production cut – which could pressure the stock."

GM to make most cars LTE hotspots for 2015

General Motors isn't the first automaker to deliver in-car Internet access, but a proposed plan announced today could make the technology more widespread than any of its competitors have offered. By the 2015 model year, most Chevrolet, Buick, Cadillac and GMC products in the US and Canada will offer 4G LTE mobile broadband access. Initially, GM will just be pairing with AT&T to deliver this service, but additional carriers will be revealed in the future.
Current in-car Wi-Fi hot spots are limited to 3G, but GM says that 4G LTE is 10 times faster than 3G service and will allow for full Internet access, including streaming video for entertainment as well as services like real-time traffic updates and navigation driving directions. There is also no need for a paired smartphone with this new system, which should make it easier to use, and GM and AT&T will also be working together to develop new apps for customers.
Buyers can expect to start seeing 4G LTE in their cars starting next year, and GM is already planning to expand the service to other global markets as well. All of the information from GM's announcement is posted in a press release below.
