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.

The next gen Volt is what has kept me from simply buying an EV now. The rumors say its only going to be a slight improvement with slightly better range on battery. If that's so I'll pass and get a full EV (maybe the Mercedes). But if they pop it up to an 80 mile range and have the generator and still keep it under $40k before rebates, I'm sold.

One thing I do not understand is why battery capacity is not an upgradable option. Most cars give us various engine sizes, why not give us larger battery options? Tesla does it, I'd love the option to buy out my range anxiety. That Toyota Rav4e has fantastic range (125+ miles in testing) but you can't find it anywhere but Cali. I'd love to get a commuter car with range around 100 miles...

No way in hell will the next Volt have 80 miles range. 50 if we're lucky.

The priority for the Volt needs to be cost reduction, performance, and looks (basically the fundamental pillars of any car). There are a lot of PHEV competitors coming with far less range, so it's the other metrics that GM needs to win on.

There is no point in simply bumping the specs on a crappy, ugly car that nobody will buy anyway.

A larger battery would be nice but not necessary. If you charge at work, the Volt already offers 80 electric-only miles every single day. That means there's also no real need for a more efficient engine. The Volt already gets 37mpg and 90% of your driving will already be electric anyway.

What they really need is to make it look better, and add a fifth seat. There's no reason the Volt couldn't have looked like a smarter Chevrolet Cruze, instead of one with Down syndrome.

If they get the MSRP under $30k, with the federal rebate alone, that's only $22.5k. For a car that can do 15,000+ pure electric miles per year, while still carrying a gas backup.

The Volt isn't ugly IMO. My eyes nearly bulge out of their sockets whenever I see one! Red or blue is the best colored Volts. I wish the belt line wasn't quite as high though.
