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.

Chevy might've pulled out of NASCAR if it weren't for new Gen 6 car

We've been on the fence with NASCAR for some time now. On one hand, it's some of the closest racing anywhere in motorsports, with actual passing and door-handle-to-door-handle action as a matter of course. But on the other, it's become template racing - a personality-driven sport more about the drivers than any sort of loyalty to a particular automaker. The Car Of Tomorrow format really rammed that message home, with a racecar's identity coming down to little more than headlamp stickers slapped on the nose. That's not necessarily a bad thing in and of itself, but we've wondered for some time what's in it for the automakers, who pay big money to stay in a series that has had little increasingly little do with street car sales, let alone innovation.
Apparently General Motors was beginning to wonder the same thing. In a new ESPN report, Rick Hendrick, team owner of Hendrick Motorsports, suggests that GM would have seriously considered leaving NASCAR if it wasn't for the move away from the COT to the new Gen 6 racer. According to Hendrick, GM North America boss Mark Reuss spearheaded the charge away from the 2007 COT and toward a racecar with clearer automaker ties - cars like the new Chevrolet SS racer shown above.

Now, if we could just get more rear-wheel drive V8 coupes into showrooms....

Best-selling vehicles by state

America loves trucks. According to Edmunds, which has tracked the best-selling vehicles by state based on new vehicle registrations, 40 out of 50 U.S. states’ best-selling vehicle is a pickup. Most often, thatÂ’s the Ford F-Series, but occasional Chevy, Ram and even Toyota top the lists. Here, weÂ’ve compiled the best-selling vehicles by state, including the four runners-up for each state. Interestingly enough, only one EV shows up in a stateÂ’s top five (Tesla Model 3 in California). Read on below to see whatÂ’s most popular in your state.
