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 raises 2023 guidance on strong sales, higher profits

General Motors beat first-quarter profit estimates and raised its full-year earnings and cash-flow guidance after vehicle demand at the start of the year surpassed expectations. Its shares rose in premarket trading. GM made $2.21 a share in adjusted profit in the first quarter, compared to a consensus forecast of $1.72 a share. Revenue rose 11% to $39.99 billion, it said Tuesday, which was more than the $39.24 billion analysts expected. The stronger results stem from rising sales in the US, even in the face of higher interest rates and inflation. GM executives said demand was strong enough to revise 2023 guidance upward, boosting profit estimates for the year by $500 million to between $11 billion and $13 billion. “We did it with strong production and inventory discipline and consistent pricing,” GM Chief Financial Officer Paul Jacobson said on a call with journalists. “All in all, weÂ’re feeling confident about 2023.” The Detroit automaker raised per-share full-year guidance to between $6.35 and $7.35, up from $6 to $7 a share, and said free cash flow would also increase by $500 million to a range of $5.5 billion to $7.5 billion.  GMÂ’s shares pared a gain of as much as 4.4% before the start of regular trading Tuesday, rising 3.5% to $35.50 as of 6:55 a.m. in New York. The stock was up 1.9% for the year as of the close on Monday.  North American Strength The automakerÂ’s sales were particularly strong in North America, where first-quarter earnings rose before interest and taxes rose to $3.6 billion. Vehicle sales rose 18% to 707,000 in the region. Jacobson said the company originally expected to sell 15 million vehicles in the US this year, slightly less than the 15.5 million annualized rate automakers foresaw in the first quarter. North American demand was enough to offset a weak performance in China, GMÂ’s second-largest market. The automaker continues to struggle in the country, where its vehicle sales fell 25% to 462,000 vehicles in the quarter. Profits from its joint ventures in the market slumped 65% to $83 million.  The market has struggled overall in the wake of Covid-19 restrictions and foreign automakers have had to overcome a growing preference for Chinese brands by competing on price, squeezing profit margins. The situation in China probably wonÂ’t significantly improve until the second half of the year, according to Jacobson. GM remains on target to sell 150,000 electric vehicles this year, the CFO said.

2017 Chevy Bolt EV arrives in late 2016 with 200-mile range

For those keeping track, the production 2017 Chevy Bolt that was just revealed at CES in Las Vegas is, well, pretty much just what we were expecting. As promised, GM claims the EV crossover-ish hatch will have a 200-mile range, and be "affordable." While pricing hasn't been announced, we've posited in the past that "affordable" is code for around $30,000 after incentives. The Bolt will use a couple of features, both novel and expected, to enhance range. The EV is expected to use information on the owner's driving history, the weather outside, the terrain, and even the time of day to help manage and predict range. The nav system will optimize routes to conserve range, if needed, and show nearby charging stations. That should ease, if not eliminate, range anxiety. Another range-conserving feature is a low-draw Bluetooth system. Speaking of charging stations, there's no word so far about how long it'll take to recharge a Bolt, or the capacity of the battery pack. Inside, the large center-mounted MyLink screen measures a full 10.2 inches, and provides a display for the wide-angle rear camera with a birds-eye view capability. OnStar provides 4G LTE and a wifi hotspot to occupants, and the sorts of efficiency and driving habit apps you'd expect will be available. It seems like remote start and cabin preconditioning will be standard. Interestingly, the Bolt will feature "Gamification" features intended to promote efficient driving by pitting Bolt drivers against each other for green driving awards or rankings. Details on are sparse on this feature, but then again, information on the Bolt in general is a little sparse right now. If you want to know things like detailed specs, the specifics of chassis componentry, or even trims and options, you'll have to wait. Check out our first quick spin of a prototype Bolt in Las Vegas for a preview of what GM's EV is like on the road. Chevrolet Introduces 2017 Bolt EV First long-range, affordable EV with customer-focused connectivity LAS VEGAS – Chevrolet is introducing the 2017 Bolt EV at the Consumer Electronics Show, fulfilling its promise to offer a long-range, affordable electric vehicle for the masses. The Bolt EV, which will go into production by the end of 2016, will offer more than 200 miles of range on a full charge. It also features advanced connectivity technologies designed to enhance and personalize the driving experience.
