2014 Chevrolet Corvette C7 Convertible offers a few more views before reveal

Over the weekend, Chevrolet released its first images of the new 2014 Corvette Stingray Convertible. Now, ahead of the droptop's official introduction tomorrow at the Geneva Motor Show, the automaker has given us a few more shots of the softop C7 showing off the car's rump albeit from a high, strategically positioned angle.
From this angle, it's hard to get a sense for how long and flat the decklid really is, but we can easily see that, like the rest of the C7's design, the new convertible's decklid and tonneau cover are far more detailed than the current car. We also get a better look at the rear haunches sans brake vents, which have apparently been moved to underneath the car in order to accommodate the top's hard cover.
As for the overall styling of the C7 convertible, with the top erected, we get some idea of what a coupe design (as opposed to the Stingray's fastback shape) would look like on this car. The C5 Corvette most recently had a coupe model that did away with the large glass hatchback, and we recently reported on a low-cost "coupe" model potentially being added to the C7's repertoire.

Chevy Volt replacement battery cost varies wildly, up to $34,000

There's a growing hubbub in the plug-in vehicle community over what looks like some ridiculously cheap replacement batteries for the Chevrolet Volt going up for sale. GM Parts Online, for example, is selling a replacement Volt battery with an MSRP of $2,994.64 but, with an online discount, the price comes down to $2,305.88. For the 16-kWh pack in the 2012 Volt, that comes to a very low $144.11 per kilowatt hour (kWH). But is it a real deal? How can it be, when a Chevy dealer may quote you a price of up to $34,000 to replace the pack? For a 16-kWh Volt pack, $2,305.88 comes to a very low $144.11 per kWh. But is it a real deal? Battery packs in alternative propulsion vehicles are usually priced by the kWh and, historically, they've been thought to be in the range of $500-per-kWh for OEM offerings. Since automakers are understandably secretive about their costs, we still don't know what the real number is today, but we do know it varies by automaker. Tesla, for example, has said it pays less than $200-per-kWH at the cell level but, of course, a constructed pack would be more. Whatever is going on, li-ion battery prices are trending downward. So, $144.11 certainly sounds great, but what's the story here? Kevin Kelly, manager of electrification technology communications for General Motors, reminded AutoblogGreen that GM Parts Online is not the official GM parts website and that, "the costs indicated on the site are not what we would charge our dealers or owners for a replacement battery. There would be no cost to the Volt owner if their battery needs replacement or repair while the battery is under the eight year/100,000 mile limited warranty coverage provided by Chevrolet." A single price tag also can't be accurate for everyone, Kelly said. "If the customer needs to have their battery repaired beyond the warranty, the cost to them would vary depending on what needs to be replaced or repaired (i.e. number of modules, which specific internal components need replacement, etc.)." he said. "So, it's hard for us to tell you exactly what the cost would be to the customer because it varies depending on what might need to be repaired/replaced. As a result, the core charge would vary." But, is the $2,300 price even accurate for anyone? Thanks to a reader comment, we see that this similar item on New GM Parts makes it look like the lithium-ion modules that Kelly mentioned – where a lot of the expensive bits are – are not included.

Chevy's low-cost pedestrian avoidance to debut on 2016 Malibu

The mainstreaming of safety technologies that began on luxury vehicles will get a big boost from General Motors later this year. The General says it plans to offer 22 driver assistance systems across its product portfolio of 2016 models, starting with the redesigned Chevrolet Malibu - the one that we know will keep tabs on teenagers for the benefit of parents. Pedestrian avoidance will be another of its available options. Instead of kitting the sedan out with numerous and expensive radar arrays, the GM system uses the camera mounted next to the rearview mirror that is already used for the lane-keeping function. New software lets it detect pedestrians, and when it detects a potential collision with one, it can alert the driver and brake autonomously if the driver doesn't react. Eventually, engineers want to give it the ability to do the same with cyclists. Because it uses existing hardware updated with new code, GM says the application costs "a few hundred dollars." GM demonstrated the Front Pedestrian Braking preventing a crash with a dummy pedestrian at speeds up to 15 miles per hour. Automotive News reports that it will reduce the severity of impact up to 40 miles per hour, but "may not be of much use in collisions at higher speeds." That feature will also join the options list of the Cadillac CT6. The press release below has more on GM's driver tech soon on the way.

Safety engineers will develop and test these and other safety technologies for products around the world at GM's new, 52-acre Active Safety Test Area at its Milford Proving Ground near Detroit. The $14 million facility officially opened Friday. "Our comprehensive safety strategy of helping customers before, during and after a crash continues," said Jeff Boyer, vice president of GM Global Vehicle Safety.
