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.

Autotrader picks best cars for 2015's college grads

Summer is here and the school season is winding to a close. That means millions of students will be graduating college and (hopefully) entering the workforce. For many, that will mean buying a new car suited to the new stage in life into which they will now be embarking. That can be a bewildering choice, especially for someone who's never bought a car before. Fortunately, Autotrader has come up with a short list of recommended cars – new and used – which it recommends to the graduating class of 2015. Among the site's top choices are some compelling crossovers and hatchbacks, including the Buick Encore, Chevy Trax, and Jeep Renegade, as well as the Honda Fit, Nissan Versa Note, Mazda3 and Fiat 500. Can't stretch to buying new, or don't see the point? Autotrader has also identified the Toyota Camry, Ford Fusion and even the Lexus IS as smart buys in the certified pre-owned category. "Any time someone goes through a major life change, such as graduating college, they need to determine if their current ride makes sense for their lifestyle, from both a financial and functional perspective," says Autotrader editor Brian Moody. "For example, while that hand-me-down SUV from your parents was nice when you turned 16, you may want to opt for a safer, more fuel-efficient car as you transition into the working world." Autotrader Names 10 Best Cars for Recent College Graduates ATLANTA, May 28, 2015 /PRNewswire/ -- For many, graduating college is a milestone like no other – it represents a new chapter, a proud accomplishment and, fortunately or unfortunately, financial independence.

This 450-hp electric Lotus Evora is powered by Tesla and Chevrolet

When someone mentions an electric Lotus, the first thing that comes to mind is the Tesla Roadster, the California-based automaker's first vehicle. That car started life as an Elise before being heavily massaged and adapted by Tesla's engineers. In a similar spirit, the people at Onpoint Dyno are close to finishing Blue Lightning, a track-ready all-electric Lotus Evora. Blue Lightning uses a Tesla drive unit and a Chevrolet Volt battery pack, both mounted in the middle in place of the Evora's 3.5-liter Toyota V6. It's putting down about 450 horsepower at the wheels. The car was built for time attack sessions, so power is fed through custom forged wheels and super sticky Pirelli PZero Trofeo R tires, the same ones found on the last Chevrolet Camaro Z/28. There is a custom digital instrument cluster in place of the Lotus gauges. There's also a regen paddle on the left side of the steering wheel. With a full charge, Blue Lighting should go about 120 miles. While the car runs under its own power, it's only about 90 percent complete. It has no power steering, no firewall in between the seats and the motor and battery pack, no A/C, and a large hole where the shift lever used to be. Other final touches include fine-tuning the brakes and suspension. There is also a custom rear bumper coming that should make it look more like the new Lotus Evora 400. Onpoint Dyno expects the car to hit the track in the next month or so. Related Video:
