The 2015 Chevy Spark EV uses a new battery pack, compared the previous model year of the small electric car. For 2015, General Motors brought assembly of the Spark's battery pack in-house to its plant in Brownstown, Mich. That’s where GM builds batteries for the Chevrolet Volt, Opel/Vauxhall Ampera, and Cadillac ELR.

The move represents improved manufacturing efficiencies. The pack for the 2014 Spark EV, produced in a small run of about 1,000 units, had been assembled by Compact Power Inc. in a Michigan plant—but then shipped to South Korea for installation in the EV.

The new pack is smaller, lighter and more efficient—with a drop in energy storage from 20 to 19 kilowatt-hours, while shedding nearly 90 pounds. Yet, the net result in terms of range (at 82 miles per charge) and efficiency (118 MPGe) are not changed. GM switched suppliers, now using LG Chem instead of A123 Systems.

The chief selling point for Chevy Spark EV is its high torque. The 2015 model swaps out a 3.17 final drive ratio axle for a 3.87 version, a move that retains torque but, as described by GM engineers, provides a benefit to city driving range.

The list of other miscellaneous updates include cosmetic items, such as no longer offering the Titanium body color, and the use of a large EV Eco badge. In the 2LT version, the interior’s Electric Blue trim and accents are dropped and replaced with Silver. For both 1LT and 2LT trim levels, the instrument panel cluster surround changes from Electric Blue to Piano Black, while stitching on shift boot cover and leather-wrapped steering wheel changes from Electric Blue to Black.

Like the gas version of the car, the Spark EV model in 2015 adds OnStar 4G LTE with Wi-Fi hotspot capability.
