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 profit dips on truck changeover, but beats estimates

DETROIT — General Motors on Thursday reported a higher-than-expected quarterly profit despite a drop in production of high-margin pickup trucks, as it gears up for new models that are expected to boost profits next year. Like rivals Ford and Fiat Chrysler Automobiles, GM is banking on highly-profitable Chevy Silverado and GMC Sierra pickup trucks to lift profits, as consumers shift away from traditional passenger cars in favor of these larger, more comfortable trucks, SUVs and crossovers. During the first quarter, the process of changing over to GM's new pickups resulted in a drop in production of 47,000 units. GM Chief Financial Officer Chuck Stevens said the production drop had resulted in a drop in pre-tax profit of up to $800 million. Earlier this year, GM said its 2018 profits would be flat compared with 2017, but expected its all-new pickup trucks would boost margins starting in 2019. On Thursday, GM reiterated its full-year 2018 forecast for adjusted earnings in a range from $6.30 to $6.60 per share. The automaker said capital expenditures were more than $500 million higher in the quarter because of investments its new pickup trucks and a family of low-cost vehicles under development with Chinese partner SAIC Motor Corp. On Wednesday, rival Ford said it would stop investing in most traditional passenger sedans in North America. CFO Stevens told reporters on Thursday that GM has "already indicated that we will make significantly lower investments on a go-forward basis" in sedans. 2019 GMC Sierra View 21 Photos GM benefited from a lower effective tax rate in the quarter, but adjusted pre-tax margin fell to 7.2 percent from 9.5 percent a year earlier. Stevens said the company's profit margin should hit 10 percent or higher in the second quarter and for the full year. GM said material costs were $700 million higher in the first quarter, and it expects those costs to continue rising. The automaker said it would counter those increases with cost cutting measures. "It is a more difficult environment than it was three or four months ago," Stevens said when asked about rising commodity prices from potential steel and aluminum tariffs announced by the Trump administration. "But we are confident we can continue to offset that." The company reported quarterly net income of $1.05 billion or $1.43 per share, a drop of nearly 60 percent from $2.61 billion or $1.75 per share a year earlier. Analysts had on average expected earnings per share of $1.24.

Chevy Volt outsells Nissan Leaf for first time since October 2013

It's been a rough summer so far for both the Chevy Volt and the Nissan Leaf, the first two plug-in vehicles from major automakers that ushered in the modern plug-in era. In June 2015, sales were down from their 2014 levels. The Leaf was down 11.6 percent and the Volt was down 31.1 percent. For July 2015, things didn't get much better. July 2015's Volt sales of 1,313 were down 35 percent from July 2014 and are down 34.8 percent for the year-to-date. Nissan, on the other hand moved only 1,174 Leafs last month, down 61.1 percent. So far this year, Leaf sales are down 30.2 percent. What's interesting with this steep decline in Leaf sales is that allowed the Volt to outsell the Leaf for the first time since October 2013. Back then, the Volt sold 2,022 compared to the Leaf's 2,002 units. So far, Nissan has sold 83,312 Leafs in the US since the EV went on sale in late 2010. Chevy has sold 80,292 Volts. Even though Tesla doesn't release monthly sales figures, there's a good chance that the pricey Model S was once again the best-selling EV in the US in July, as it was in the first three months of 2015. At that time, Tesla delivered an average of just under 2,000 Model S EVs a month. We might get some insight into more recent numbers during the quarterly investor call on Wednesday. As we've said before, the low sales for the aging plug-ins can be explained by the fact that both the Leaf and the Volt are due for upgrades. The second-gen Volt is coming in a few months. Nissan is being cagey about when the updated Leaf will arrive, but given these latest sales figures, we wouldn't be surprised if the undisclosed timetable gets move up somehow.
