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.

MotorWeek looks back at 1995 Chevy Tahoe, GMC Yukon

MotorWeek's Retro Review series gives us a nostalgic look back at some of the best sports cars and luxury sedans available in the 1980s and '90s. For its latest clip, the show shifts gears to remember the 1995 Chevrolet Tahoe and GMC Yukon. Similar to the success of crossovers today, SUVs were tallying big sales and making big money for automakers in the mid-'90s. The Tahoe and Yukon filled slots in the market as steps down from the larger Suburban. These twins weren't wanting for space, though, with plenty of room to haul around a family. MotorWeek came away generally impressed too, and called the models some "of the better riding sport utilities we've ever experienced." This review comes with some jazzy, electric guitar licks to enjoy in the background.

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.
