Chevy Bolt EV's battery shows big improvements over Spark's

Plug-in vehicle battery technology moves fast, and all you need to do to see this in action is to take a look at the new 60-kWh lithium-ion pack inside the 2017 Chevy Bolt EV. Well, you need to do that and then compare it to the battery packs inside of GM's other plug-in vehicles. And you don't even to go as far back as the EV1 to see progress. Let's start with what we know about the new Bolt's pack. It is supposed to drive the Bolt EV over 200 miles on a full charge. It weighs 960 pounds and is made up of 288 cells. Chevy's other all-electric car, the limited-availability Spark EV, had a 19-kWh pack and offered 82 miles of range. It had 192 cells and weighed 474 pounds. So, in the few years since the Spark EV was released, GM engineers have figured out how to get three times the energy capacity and almost two-and-a-half times more range out of a pack that weighs only about twice as much. And that doesn't even get to the price drops. GM has figured out how to get 3x the energy capacity and almost 2.5 times more range out of a pack that weighs only twice as much. Speaking of those 288 cells, that number might sound familiar to regular readers because that's exactly how many are in the new Chevy Volt. But the packs in the Volt and the Bolt are entirely different beasts. For one thing, while the Volt cells are made by LG Chem in Holland, MI, LG Chem will make the Bolt's cells in South Korea. The cell chemistries are also different. We spoke with GM engineer Tim Grewe (again) and while he declined to answer some of our Bolt battery pack questions until more details are unveiled at the SAE World Congress in April, he was able to explain a few things. "The cell inside the Chevy Bolt EV was specifically designed for EV range so it's up on energy," he said. "That's a different cell chemistry than on the extended range Chevy Volt, which is a smaller pack, smaller energy but more power per cell. We work with all of those vehicle requirements and customer demands and we say how do we meet this and we change the chemistry to make it all work." Comparing the 60 kWh in the Bolt and the 18.4-kWh pack in the Volt is really one of those apples to oranges issues, he said. "If you look at the Volt battery pack, how it went from where it was and where it's up to, from 38 miles to 50 miles, that was basic, overall industry improvement. Now, the 18 [kWh] to the 60 [kWh] is extended range vs. EV.

2016 Chevy Volt sneak peek at CES

Here it is, folks – your first real glimpse at the 2016 Chevrolet Volt. The gasoline-electric sedan will officially debut at the Detroit Auto Show next week, but Chevy gave us a sneak peek of its redesigned Volt at a media event in Las Vegas late Sunday, as part of its CES festivities. There isn't a ton to see here, and sorry about the low quality video (and for us not standing front and center during the reveal). But we can clearly see the car's redesigned front fascia – something recently previewed at a fan event in Los Angeles. For another view, check out a high-res photo of the new Volt from our friends at The Verge, here. Chevy even tweeted a photo of the Volt's new nose on its official Volt Twitter account, which you can see below. The automaker didn't divulge any details about its new Volt, but we already know quite a bit. For starters, the Volt will use a new, 1.5-liter gasoline engine and won't require premium fuel. It'll have more EV range and a bigger battery, too. We'll have a whole mess of information when the 2016 Volt is fully revealed in Detroit in about one week's time. In the meantime, here are some more looks at the Volt, courtesy of the Twitterverse. We're so excited about #NextGenVolt we brought it out early at #CES2015!

GM recalling 15k midsize pickups over leaky brakes

General Motors has announced a recall in coordination with the National Highway Traffic Safety Administration related to the brakes on the 2015 Chevy Colorado and GMC Canyon. In the 14,838 units in the United States estimated to be affected, the front brake calipers may be leaking fluid. Needless to say, that could make them less effective, which could hinder the vehicle's ability to stop in time to avoid a collision. The affected units were all manufactured between January 6 and December 24, 2014. The fix seems simple and straightforward enough, with dealers being instructed to inspect the front brake calipers, and replace them if necessary. See below for all the details from NHTSA. RECALL Subject : Brake Fluid Leak Report Receipt Date: MAY 12, 2015 NHTSA Campaign Number: 15V278000 Component(s): SERVICE BRAKES, HYDRAULIC Potential Number of Units Affected: 14,838 Manufacturer: General Motors LLC SUMMARY: General Motors LLC (GM) is recalling certain model year 2015 Chevrolet Colorado, and GMC Canyon trucks manufactured January 6, 2014, to December 24, 2014. The affected vehicles may experience the front brake calipers leaking brake fluid. This is due to air pockets, an imperfection in the metal caliper body. CONSEQUENCE: If the vehicle experiences a brake fluid leak it can increase the stopping distance, increasing the risk of a vehicle crash. REMEDY: GM will notify owners, and dealers will inspect and replace the front-brake calipers if necessary, free of charge. The recall is expected to begin July 10, 2015. Owners may contact GM customer service at 1-800-222-1020 (Chevrolet), or 1-800-462-8782 (GMC). GM's number for this recall is 14888. NOTES: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
