2015 Chevy Spark EV gets battery overhaul after only a year on the market
Since its launch as a 2014 model year, the Chevy Spark EV has for the most part drawn rave reviews. The heart of the 2014 Spark is its 140-hp motor that makes an incredible 402 ft-lb of torque; the miniature powerplant rockets the little EV to 60 mph in just 7.5 seconds.
Update: The 2015 edition gets a reduction in torque to 327 ft-lb.
Unfortunately, the diminutive EV has only been built as a compliance car in small numbers. With the recent announcement of changes for the 2015 model, however, the possibility arises that production volumes could be increased.
The most significant change for the one-year anniversary of the Spark EV is a major upgrade to the battery. It will be reduced from 21 kWh to 19 kWh while shedding 86 pounds, bringing the pack weight to a more reasonable 474 pounds. The new smaller pack is comprised of 192 individual lithium ion cells. Most interesting is that MSRP of $27,495 and EPA-estimated range of 82 miles at 119 MPGe are expected to remain unchanged.
These upgrades were largely made possible by a transition from A123 battery cells to those made by LG Chem, which also supplies the Volt and ELR. The new battery pack will now be assembled at GM’s Brownstone Battery Assembly Plant alongside Volt and ELR packs.
