2015 Chevy Spark will have lighter, smaller battery

As General Motors gets ready to release the 2015 Chevy Spark EV, it is retooling the Brownstown Battery Assembly to build a new battery system for the chirpy little electric car. The new Spark will lose a few pounds and kWh from its lithium-ion pack, but it will keep all of it's performance specs. The current Spark EV uses a 21-kWh lithium-ion battery pack with bits made by A123 Systems (known as B456 Systems during bankruptcy). For the 2015 model, GM is going to build a 19-kWh battery system in-house that will use 192 LG Chem cells. Losing a bit of energy capacity means that the battery system for the 2015 Spark EV will be 86 pounds lighter but it will keep the EPA-rated 82-mile range and 119 MPGe. The 2015 Spark EV also keeps its $26,685 (plus destination) starting price from the 2014 model. The car will once again qualify for a federal tax credit of up to $7,500. LG Chem also supplies the cells for GM's other plug-in vehicles from its facility in Western Michigan. The Brownstown production line currently builds the battery packs for the Chevy Volt, the Opel Ampera and the Cadillac ELR. You can read our first drive of the 2014 Chevy Spark here. Brownstown Battery Assembly Expands Capabilities Will build battery system for 2015 Chevrolet Spark EV 2014-05-14 DETROIT – General Motors will bring all its electric vehicle battery building capabilities in-house with production of battery systems for the 2015 Chevrolet Spark EV at its battery assembly plant in Brownstown, Mich. "Using our in-house engineering and manufacturing expertise enabled us to deliver a battery system that is more efficient and lighter than the 2014 Spark EV without sacrificing range," said Larry Nitz, executive director of GM global transmission and electrification engineering. "Our successful working relationship with LG Chem has allowed us to deliver a new battery system for the Spark EV that helps us to better leverage our economies of scale." A newly designed battery system features an overall storage capacity of 19 kWh and uses 192 lithium ion cells. The cells are produced at LG Chem's plant in Holland, Mich. The battery system weight of 474 lbs. is 86 pounds lighter than the system in the 2014 Spark EV. The Spark EV battery is built on a dedicated production line at Brownstown, which also manufactures complete battery packs for the Chevrolet Volt, Opel Ampera and Cadillac ELR.

Driving McLaren's Sports Car and 'The Best Corvette' at the M1 Concourse | AutoblogVR

There's nothing better than a track day. Great cars on a great track are always great fun. Recently, we had the opportunity to check out the new M1 Concourse in Pontiac, MI, with two of the coolest cars in the game; a McLaren 570S and a Corvette Grand Sport. Driving the 570S was Autoblog senior editor Greg Migliore, and he didn't hold back. Getting behind the wheel of the McLaren, Greg explains that although this is McLaren's idea of a sports car, "it's all relative." Topping out at 204 miles per hour with 562 horsepower, there's no two ways about it: this thing is a monster. While the 570S was fantastic, we had another sports car we wanted to drive and editor-in-chief Mike Austin was just the man for the job. Enter the Corvette Grand Sport. Mike pushed all 460 horses of the 'Vette to the limit and came away impressed with the car, even calling it "the best Corvette." Comparing it to its more powerful sibling, the Z06, Mike goes so far as to say the Z06 has too much power, while the Grand Sport seems to be the third bear's bowl of porridge in the Corvette family... It's just right. We captured all the action of the day with 360° cameras so you can feel like you're right there in the car sitting shotgun with us! You can check out the McLaren and Corvette laps above, but the best way to view them is through the AutoblogVR app, where you can watch the videos on your VR headset or in a nice swivel-y office chair so you can take in the sights all around you. Each month, new episodes will launch on the AutoblogVR App. We'll be posting them here on Autoblog, but for the best experience, head over to the app, which you can download for free from the App store and Google Play. Be sure to try it with a cardboard viewer, too!
