Any particular reason you think GM means EPA/Real world miles rather than city/LA04 miles ?
Chevy Spark EV
General Motors is developing an electric car that has a range of 200 miles, according to Dan Akerson, the company’s chief executive.
Akerson asserted that breakthroughs in breakthrough technology could change everything. “We’re actually developing a car today which is really anathema to the way the auto industry works,” said Akerson today during a presentation at the IHS CERAWeek energy conference in Houston. He explained that G.M. is evaluating two types of technology—one that could yield 100 miles of range and the other with 200 miles. Akerson also said that G.M. is "aggressively investing" in new lightweight materials and technologies such as carbon fiber, nanosteel and resistance spot welding for aluminum structures.
During his speech, Akerson called on President Barack Obama to develop a 30-year energy policy with diverse set of technologies and fuels. Akerson referred to the expanded use of CNG for commercial fleets and trucking as a “huge” opportunity. Building more infrastructure for CNG fueling is an important step, according to Akerson. "Everywhere you look there are opportunities to seize the energy high ground," he said.
The higher ground will apparently not rule out the use of V8 gasoline engines. Akerson said that G.M., by using technologies such as turbocharging, direct injection, variable valve timing and cylinder deactivation, can keep vehicles with eight cylinders alive and well. He said that news about the death of the V8 engine has been “greatly exaggerated.”
G.M.’s effort on a longer range EV represents something of a departure for the company, which has focused its plug-in efforts on the range-extending system used in the Chevy Volt (and others plug-in hybrids that will follow.) As opposed to emphasizing the role that pure electric cars can play in serving the lion’s share of driving needs, the company for the past two years has marketed the idea that electric-drive vehicles need to have the same range capabilities as gas-powered vehicles. Its own Chevy Spark, due out later this year in limited numbers, has a range of about 75 miles.
The evaluation of an EV with 100 miles of range, alongside a 200-mile vehicle, is somewhat odd, considering that many of today’s electric vehicles already have nominal range ratings of more than 100 miles using current battery technology.

OK, Bermin, we get it you are not a GM fan - 'more V8 gas cars' in the headline of your thread is an out of context cheap shot at what he said.
I don't think it's odd at all for GM to be dabbling with long range BEVs, just as Ford has its Focus EV, its hybrids, and its PHEVs. The Volt is becoming a success story, leading the way down one electric avenue, but thanks to Tesla, pure BEVs don't have to be defined by their limitations and therefore it is smart for GM to be exploring just where the sweet spot is where BEVs belong in the mass marketplace.
The Spark on the low end, maybe a 150 mile BEV on the higher end. I salute GM for acknowledging what Tesla is opening up in the marketplace, and perhaps we'll see a Tesla Model S compete with a Cadillac BEV in the 150+ mile range class in the near future.

I may be odd man out here, but I have always thought 200 miles in a BEV is kind of a minimum Goal Post, such as, oh ok if it has to be as little as 200 miles I'll take it.. Thats why I jumped on the Tesla Roadster.. (244 miles ideally - sometimes you can even do better than that).
Companies to satisfy people like me have to keep pushing the battery size goal post down the road. Lead Acid technology was pretty stagnant after 120 years , and the needs of Laptop computers and cell phones are what pushed the battery industry to develop lithium ion. This pressure needs to continue so that 50 years from now your grandkids aren't still buying 60 mile range cars.

I managed to get 82miles regularly with 100%charge on my '12 LEAF. Now with my '13 VOLT I get around 26-30miles on battery before it switches over. It stays plugged in over night too. Temperature I believe is the major factor on my range. A slighlt larger battery pack and/or the ability to suck down more battery than the current level (understanding this is a protection by GM/Engineers on the battery life)
So with that being said, I guess the only way is to boost up the battery from 16.5-20kWh.
a 200mile EV + Gas would be ideal in any situation. I feel an honest (worst case scenerio) hard 50 mile EV + Gas is the sweet spot

The exact optimum of EV range will be different from person to person but every EV car would benefit from an on board Rex. Even a Tesla could use a Rex to improve its overall performance in cold weather, its energy flexibility and its overall range, especially on the cheaper 45 KWh version.
One should be able to buy an EV with the EV miles of his choice and with the Rex of his choice. EV miles from 30 to 300 miles and Rex from 5 KW to 200 KW. My own sweat spot would 75 miles/15 KW but everyone should be able to choose his own just like for a standard car choice of 1000cc or 8000 cc L4 or V8.

+1. We need the manufacturers to come up with models that have REx and battery options.
BTW, that 15KW generator would be too underpowered to go on the highways. BMW i3's 25 KW is not good enough to up on slight inclines at freeway speeds, though it can do flat 70mph on freeways.

An REx (range extender?) isn't just an REx. With a 'pure' EV like the LEAF, the vendor has no choice but to give you access to 'too much' of the very expensive battery's capacity - at the cost of its longevity. A REx gives the designer more latitude in adding features to protect the EV owner's battery investment.
It seems pretty clear to me that, absent some major development in 'breakthrough' EV technology, GM with its Volt has hit upon the winning formula. I have about 1300 miles on my Volt and have used 1.7 gallons of gas. My longest drive is 30 miles - up a 6000 foot elevation gain. It would have been nice to be able to stay with my 'pure' EV LEAF. But after 14 months those climbs and the Arizona heat were beginning to take their toll.
Apparently quick-charging doesn't take as big a toll on battery life as deep cycling. IF this is 'the answer' then as soon as somebody plunks down a couple of million quick charging stations 'pure' EVs may be viable.
In the meantime, I hope GM has the good sense to stay with Volt technology.

Maybe he meant "real world" miles. NOT those "fake ideal miles".
The only car that has more than 100 miles range for sale is the e-Rav4 and Tesla. Both are built by Tesla.

200 miles BEV would cost probaly $10k more than the 100 miles EV. That is significant price difference. And it will weigh more as well... There is NOTHING wrong with giving consumers choice...
