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 exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.

Chevy, Kid Rock in Confederate flag row with civil rights group

Two of Detroit's own are ensnared in controversy today. In an interview with Fox News' Megyn Kelly, mulleted musician Kid Rock told those protesting the Confederate Battle Flag to "kiss my ass." Now, Chevrolet, which is sponsoring Rock's summer concert tour, is under fire for its support. "We are committed to our sponsorship of Kid Rock's summer tour and are confident that he will provide his fans, many of whom are proud Chevrolet owners, with a spectacular concert experience that celebrates American Freedom," a Chevy spokesperson told The Detroit Free Press last week. The company also uses the Kid Rock anthem Born Free in its pickup truck advertising. The company's position is not sitting well with the Detroit chapter of the National Action Network, though, which has called on GM to pull its support for the embattled artist. "It's obvious to us that, by supporting [Rock], while he's making inflammatory statements, General Motors becomes an accomplice if they allow him their support to stand behind his statements," the Rev. Charles Williams II, NAN's Detroit chapter director, told the Freep. As controversial as Rock's comments are, it's not entirely clear when the last time he actually waved that flag was. The Freep reports that several concertgoers don't recall seeing the flag during his most recent tour, or even over the last few years of concerts. In a 2002 interview with the paper, Rock, real name Robert Ritchie, said that the flag had been used as a symbol of southern rock and a rebel spirit, saying: "It's not about hatred or being a racist. I like Southern rock music, and a lot of people died under that flag for beliefs they had, right or wrong. But it stands for rebel, and my love of Southern rock." Related Video:
