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.

It's possible to go 111 miles on electricity in the new Chevy Volt

Wayne Gerdes at CleanMPG put the 2016 Chevrolet Volt in Premiere trim through a few closely watched on-the-road tests over a few days. One of them was a run from full charge to EV-only exhaustion, and at the end of the trip Gerdes had traveled 111.0 indicated miles on a single charge, 111.9 according to his Garmin. What's the catch? He guessed his average speed was about 20 miles per hour, which was 15 and 20 mph around town and "a few miles" at 50 mph on the highway. The EPA says the new Volt should go 53 miles on battery power. In the 2011 Volt, rated at 38 electric miles, Gerdes got 75.5 miles on a charge. The upshot is that at urban driving at average speeds should get drivers the EPA rated 53 e-mpg without fuss. He wasn't so impressed with performance in Charge Sustaining Mode, though. During one run that covered 101.2 actual miles in CSM, using 1.691 gallons, the Volt got 59.8 mpg. Speaking of driving in CSM only, Gerdes said it's less efficient here than in competitors from Toyota, Honda, and Hyundai, but that's one of the few performance-related complaints he had. Elsewhere around the PHEV, Gerdes liked improvements to the eight-inch display and rear-view camera, build and design quality, the much quieter ride, and the switch to regular fuel. The six-foot Gerdes found the cabin space still cozy, especially in the back where ingress and egress could be a challenge for people of a certain stature. He lamented the fact that he couldn't find instantaneous fuel and energy consumption or among the many readouts, and would prefer the sedan kicked into glide mode sooner. In spite of that, he declares the Volt II "a full blown electric car." Head over to CleanMPG for the rest of his assessment.

1983 Motorweek showdown pits Porsche 928S vs. Chevy Camaro Z28

Last month, Motor Trend threw the Camaro Z/28 and Porsche 911 GT3 into the bear pit and let them fight it out. Way back in 1983, MotorWeek had the same idea, comparing the Camaro Z/28 to the Porsche 928S. At the time, the Camaro was America's best selling sports coupe, the 928S was Porsche's top-of-the-line model that also had the highest top speed of any car sold here. And the price differential was even more stark then: $13,600 for the Camaro, $45,000 for the Porsche. That put the Z/28's cast-iron, 5.0-liter V8 with 190 horsepower and 240 pound-feet of torque against the all-aluminum 4.7-liter V8 with 234 hp and 263 lb-ft in the 928S. Even with that and the Camaro being 14 inches longer than the Porsche, the American was a surprising 40 pounds lighter than the German. The show took them to Summit Point Raceway in West Virginia to see how close a relative performance bargain could hang with a the German GT. Both had five-speed manual transmissions, but the high-speed corners and tight sections of Summit Point would test other handling variables, including the "bone-rattling" Camaro's solid rear axle and disc and drum brake setup vis-a-vis the four-wheel disc brakes and independent suspension on the "firm-but-smooth" Porsche. Paradoxically, the larger disparity 22 years ago resulted in a closer result. Check out the video to see how the Summit was won.
