New battery pack was designed in-house and uses LG Chem cells

General Motors is looking to quickly advance its efforts in battery development and production for its electric vehicles. The company is capitalizing on those efforts this week with the announcement that the 2015 Chevrolet Spark EV will receive a lighter lithium-ion battery pack.
 
The current Spark EV makes use of a 21-kWh battery pack that was developed by A123 Systems. This time around, however, General Motors designed the battery pack in-house using 192 lithium-ion cells provided by LG Chem. Weighing in at 474 pounds, the new battery pack is 86 pounds lighter than before.

 
Despite the slight downgrade in storage capacity from 21-kWh to 19-kWh, General Motors says that the Spark EV’s EPA-rated range and MPGe remain steady at 82 miles and 119 MPGe respectively.

The Spark EV is priced at $27,495 before a $7,500 federal tax credit. Depending on where you live in the United States, that figure could drop even further thanks to state credits and rebates. For example, residents in California could qualify for a $2,500 state rebate on the purchase of a Spark EV. That would bring the overall cost of the vehicle down to $17,495 compared to $12,170 for the base, gasoline-engine version of the Spark.

It really does not compute. If you decrease the weight, you increase the vehicle efficiency thus MPGe should be affected. If you increase the depth of discharge (use more of the battery), then the kWh rating should rise. They should stop reporting actual capacities, and start reporting USABLE capacities of batteries.

Or even better, both total and usable.

Well there's your answer. They don't do that, and I doubt they ever will.
