2015 Chevy Spark EV

2015 Chevy Spark EV gets battery overhaul after only a year on the market

Just a year into its life, the Chevy Spark EV will be updated for 2015 with an entirely new battery pack. The change will reduce costs and is indicative of GM’s sincere interest in building quality electric vehicles.

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.

Luke, buddddy.. You're tripping man. You mention a MSRP in the article but don't state it. You refer to a final drive ratio with the number 8 ? huh, whaaat? Please provide the estimated MSRP and clarify the final drive ratio. With out a doubt, EV has a viable place in personal transportation development. Will G.M. step up to the task, who cares? We still have a very wide price gap between viable( general application) and what is considered in the working world as affordable transportation. Wishing you a fantastic weekend and thanks for the good read.
Final drive ratios are a bit different in the battery EV world, Parks. Electric motors can spin up to 12,000 RPM, and with typical BEVs the only gear reduction comes in the form of a single final drive ratio. The Model S, for example, has a single fixed speed 9.73:1 reduction ratio. The LEAF is about 7.94:1. That is why the final drive ratio of 3-something for the Spark EV is unusual. You are correct that I should have included the MSRP, though; my apologies.
Yes the final drive ratio of 3.87 might seem high at first but the motor in the car delivers an astounding 400 foot-pounds of torque so it still should perform great.
I notice no mention of the torque rating decreasing considerably on the Chevy Spark EV. The 2015 model is listed as having 327 ft lbs right out on the Chevy site vs 402 ft lbs for the 2014 model.
Good catch, Craig. That wasn't up there when I wrote this article but I made a note of it in the first paragraph.
