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.

Cadillac CT6 production ceases January 2020 as part of D-Ham layoffs

General Motors filed paperwork under the Worker Adjustment and Retraining Notification Act with Michigan's Department of Labor and Economic Opportunity this week, detailing events to come at the automaker's Detroit-Hamtramck Assembly Plant. Starting February 28, 814 salaried and hourly workers at D-Ham, as its called, will be laid off. The 753 workers represented by the UAW will begin receiving offers in January to relocate to facilities in Michigan and Ohio, or buyout offers. As the 4-million-square-foot plant winds down through April 3 to a skeleton crew, the Cadillac CT6 ceases production in January 2020, and the last Chevrolet Impala comes off the line on February 28. The loss of the CT6 represents the end of Cadillac's latest brief, and highly regarded, adventure into flagship sedans. It might also mean the end of the 4.2-liter Blackwing twin-turbo V8 engine, at least for the moment. Both casualties are calamities. The death of the Impala closes the door on a nameplate in production for 52 years since 1957, having started off as a top-tier trim for the 1958 Bel Air known as the Bel Air Impala, once advertised with the line, "Lets you know you're the boss." As part of the new four-year labor agreement with the UAW, GM is keeping D-Ham open to build a new line of battery-electric vehicles, ultimately investing $3 billion and tripling employment to 2,225 workers when fully operational. The agreement described the coming EV as a "van" that would commence production in late 2021, but various reports say what's actually coming is a range of premium EVs in pickup and SUV bodystyles under the program codename BT1. The easy predictions put an electric GMC Sierra and Cadillac Escalade among the EV fold, but not until 2023, according to auto industry forecaster LMC Automotive. Before that, LMC claims an electric van will debut in late 2021, along with a battery-powered rebirth of the Hummer brand in pickup and SUV forms, also in late 2021. 

2014 Chevy Silverado High Country spied wearing trappings of new luxury trim

Spy photographers have spotted the new Chevrolet Silverado High Country and GMC Sierra Denali out on public streets for a little testing. From the looks of things, the Silverado will receive a much-differentiated front fascia along with special badges and those honking 20-inch chrome wheels. Expect to find a more posh interior as well. Likewise, the Sierra Denali will wear a tweaked nose with the familiar Denali bling. The one of the GMC trucks spotted here rolls on 21-inch gunmetal wheels instead of the 20-inch chrome pieces of the High Country.
Word has it both trucks will go on sale after the Texas State Fair this summer. While General Motors hasn't said for certain what we can expect to find under the hood, we'd be surprised to see anything outside of the range of engines found in the standard Silverado and Sierra models. That means buyers should be able to get their hands on the efficient, 23-miles per gallon 5.3-liter V8.
