GM uses wind power to build SUVs, trucks

This week started with a chill, as the Intergovernmental Panel on Climate Change issued a dire report with scientists warning, "The world we know today is not the world we will see in 50 years," with temperatures rising at their current rates. In the meantime, the trend toward purchasing more SUVs and crossovers continues. Most automakers, though, have set goals toward more sustainable production. That includes General Motors, which, somewhat ironically, plans to use wind power to produce many of its vehicles, including pickups and full-size SUVs. As the Detroit Free Press reports, several wind farms are coming online to support cleaner production as part of a partnership between GM and energy producer CMS Enterprises. At the beginning of October, the 100-megawatt Northwest Ohio Wind Farm began producing energy, supplying GM operations in Ohio and Indiana, where manufactured vehicles include the Chevy Cruze, Chevy Silverado and GMC Sierra. Hilltopper Wind Farm in Illinois will begin producing another 100 megawatts for GM manufacturing in the region. In Texas, where GM builds the Chevrolet Tahoe, Chevrolet Suburban, GMC Yukon, GMC Yukon XL and Cadillac Escalade, the automaker is getting 50 megawatts from Cactus Flats Wind Farm beginning October 9. Using wind power isn't just about being green, but also for the sake of price stability. As Rob Threlkeld, GM's global manager of renewable energy told the Free Press, "You don't get the price spikes this way, like you do with fuel, and it reduces the environment footprint of the vehicle you're driving." Threlkeld said that renewable energy has already meant "millions of dollars in savings" for GM. GM plans to power all of its global operations with renewable energy by 2050. This week, the automaker was ranked 76 on the EPA's "National Top 100 List" of green manufacturers. It was the only automotive company listed.

2014 Chevrolet Corvette Stingray Convertible gives us a couple of looks

Put away your pixel paintbrushes, kids. Pack up your Photoshop. This is the real-deal 2014 Chevrolet Corvette Stingray Convertible in its first official images. The droptop Chevrolet will roll into the bright lights of the Palexpo exhibition at next week's Geneva Motor Show, a four-wheeled statement of intent that General Motors is serious about taking its Corvette franchise global.
Chevy isn't providing anything in the way of further details with these two shots, but we've learned at least a couple of things about the car shown here. First off, the example seen in these images is fitted with the optional Z51 Performance Package - something that isn't immediately evident because there's no sign of the coupe model's prominent ductwork on its rear haunches. In order to accommodate the power folding hard tonneau cover, the vents that feed the transmission and differential coolers have been relocated to the underside of the car. The dark paint color on this example also does a good job of muting the contrasting black front fender vents and hood opening - Z51-spec design details that have proven to be somewhat controversial.
One other thing to note: These two shots also display the Stingray wearing different alloy wheels than the split five-spoke design shown at the hardtop's Detroit Auto Show unveiling in January. The simpler, thin five-spoke wheels should do a good job of showing off the Z51's upgraded brakes, and they'll be optional on the coupe as well.

First 2015 Chevy Corvette Z06 engine blows up at just 891 miles

You've waited and watched and waited some more for the arrival of your 650-horsepower, $78,000 Chevrolet Corvette Z06. Finally, that joyous day arrives and you eagerly, but gingerly, begin to break-in the 6.2-liter supercharged V8 monster under your hood. Then 900-odd miles after delivery, your excitement grinds, quite literally, to a halt. That's what the owner of one 2015 Z06 claimed happened to him when a simple break-in drive resulted in a lunched engine. The owner, known as Lawdogg149 on Corvette Forum, says he was out breaking-in his car ahead of a January track event when it happened. "While making a pull from 35 miles per hour, I accelerated and shifted short of redline, and boom - the car began knocking. I pulled over and popped the hood. I could hear a loud knock coming from the No. 6 cylinder area along with a serious, grinding, metal-on-metal sound coming from the supercharger area," Lawdogg wrote. A subsequent trip to the dealer confirmed his concerns, with the service facility telling Lawdogg that the No. 6 valvetrain had failed. The dealer couldn't research the issue further, though, as General Motors requested the engine be returned for a more thorough evaluation. The good news for the Z06's unlucky owner, at least, is that GM will be covering the engine replacement under warranty, an expense that Corvette Forum estimates is a nearly $24,000 procedure. At this point, the two leading theories behind the engine's detonation involve a manufacturing defect – which could be why GM is so keen to tear the blown powerplant down – or a mistake on the part of Lawdogg. As Motor Authority points out, such an error could be something as simple as the Z06's owner accidentally shifting to first rather than third during his 35-mph pull. If, however, there's a deeper manufacturing problem with the Z06's engine, this might not be the only case we end up hearing about.
