GM offers no details on Spark at this point

GM has been offering the Chevrolet Volt for the past year and the car has proven to be reasonably popular, even if the price keeps some away. The Volt isn't a fully-fledged EV, and has a gasoline engine/generator onboard to extend the range of the vehicle when the battery pack is exhausted.

GM announced today that it has plans to start selling a pure electric vehicle (EV) in 2013. The EV will be called the Spark and it will be a complete electric powered mini-car that is aimed at drivers in big cities. The first markets to receive the Spark EV are likely to be the same ones that welcomed the Volt.

“The Spark EV offers customers living in urban areas who have predictable driving patterns or short commutes an all-electric option,” said Jim Federico, global vehicle chief engineer for electric vehicles at Chevrolet. “It complements Chevrolet’s growing range of electrified vehicles, including the Volt extended-range EV and the 2013 Malibu Eco with eAssist technology.”

At this point GM isn't offering hard details on the Spark. We don't know the driving range, price, or anything about its performance. All we know for sure right now is that the Spark will use battery packs from A123 Systems. Those battery packs will be nanophosphate lithium-ion packs.

“Our global demo fleets continue to provide insight into the needs of electric vehicle customers living in urban environments,” said Federico. “The Spark EV is another step in Chevrolet’s plan to provide customers with a variety of electrification solutions to address the lifestyle and transportation needs of people around the world.”

It would be easy to expect the Spark to target the Nissan Leaf which has an EPA estimated driving range of 73 miles or less depending on the conditions.

That's not right. The Volt IS a fully-fledged EV that just happens to have an onboard generator.

How does taking the generator away make it more fully-fledged??

Actually that's not quite true, at high speeds and low charge, the gas engine actually does provide motive force directly to the wheels.

There's two electric motors, one of which does double duty as a generator. The two motors together have the power to drive the Volt no problem but if the charge gets down and the secondary motor is needed to charge the battery the primary motor doesn't have enough power to maintain highway speeds. At that point the gas engine kicks in and turns the secondary motor to generate charge for the primary, but it also provides mechanical power through the secondary motor to the wheels.

If it wasn't so complicated I'd call it brilliant. It might still be brilliant, but I'll be waiting at least a couple more years to hear how maintenance goes for the early adopters before I can give a full opinion of it.

You only confirm what I'm saying. The Volt is a FULLY capable EV when it is fully charged. When the generator kicks in it behaves as a hybrid to extend the range. Up until that point it is, without question, a full EV.

Removing the range extending generator and all the complexities associated with that does NOT make it more of an EV. It just makes it only an EV.

Well, by the same argument you could call a plug in Prius a fully electric car; it's true as far as it goes but doesn't tell the whole story. I suppose it's like arguing about whether a shape is a square or a rectangle. Both the Volt and the new Spark are electric vehicles, but the Volt is so much more that I have difficulty putting them in the same category.

No, not really.

The Prius PHEV is unable to complete the EPA testing cycles without turning on the gasoline engine.

The Volt is an EV until the charge is depleted. Regardless of the usage. Then it becomes a Serial/Par. Hybrid.

The Prius PHEV is an EV provided you stay below ~27 hp requirement. If at any time you exceed 27 hp, the gasoline engine turns on. This makes the Prius PHEV always a Serial/Par. Hybrid, just one with a very large reserve of initial electricity.

People seem to forget the initial NA Prius (which was already Prius 1.1) was a B-segment car that would get ~41 MPG combined on post 2008 EPA testing. Compared to the initial Prius, the initial Volt is a significant advance. Hopefully future versions of Voltec (by GM or others) shows the similar rapid advancement as the Prius platform (which is possible for "new" technology)

Yeah, I got into this argument over a year ago - any vehicle which can move via electric power is by definition an "electric vehicle". The purists disagreed and claimed that only vehicles powered entirely by electricity 100% of the time could be called electric vehicles.

Really makes no sense to me. California's definition is better (before they scrapped them). The Prius and Volt are hybrid electric vehicles. The Volt and Spark are ZEVs - zero emissions vehicles. But apparently that upset the purists too since hydrogen-powered vehicles are also ZEVs.

Factor in that over 2/3rds of our electricity comes from fossil fuels, and over 2/3rds of the remainder comes from nuclear, and I don't understand why it's so important to some people if a vehicle can only be powered by electricity.

2009 U.S. electricity generation
67.7% - fossil fuels
21.9% - nuclear
7.4% - hydro
1.9% - wind
0.4% - geothermal
0.4% - biowaste (i.e. methane from landfills)
0.2% - biowaste wood (i.e. sawdust from lumber mills)
0.02% - solar

One in which you no doubt lost.

Not if it has a gas engine. Then it's classified as this thing you might have heard of lately called a hybrid.

If by purist you mean 99.9% of the total population, then you you would be correct.

I'm not sure what's so hard about this to understand. Battery only = electric vehicle. Battery and gas engine = hybrid. End of discussion.

Battery only = electric vehicle
Battery + gas engine = hybrid gas and electric vehicle.

"Hybrid" is just an abbreviation.

I think when you define things so literally your run into the American Cheese Issue. IE, while the product may meet the literal defination of the words, it does not hold up to reasonable market expectation of product so labeled.

For example, I've owned some cars that could move due to the starter motor. Would these cars then be electric vechiles as well? Would my currect car by BioFuel car, even though it would be destroyed within a few thousand miles if I tryed to use E85 or E100?

Clearly some kind of standards need to be maintained

All "EV" labeled cars (IMO) should be
1.) Able to perform to maximum capabilities under electric power alone
2.) Be able to complete each EPA/EU testing cycle under electric power alone

If one and two are met, its really an EV then. If a Leaf owner hooked up a trailer or brough along a generator would thier "EV" suddenly be less of an EV?

Erm.. how could you argue about that, its quite well defined. All squares are rectangles, and any rectangle with all 4 sides the same length is a square.

Seems like a ruler would end your "argument" pretty quickly. :)

????

This is the dumbest logic I have ever heard of. So I guess the Boeing 747 is a "full" glider because if you cut the engines off it then becomes a full glider...

Seriously, actually think about how dumb your position is on this. Then get back to me with the proper attitude.

How so? The Volt even with an empty fuel tank perform all the functions of a "fully qualified" EV.

Just because it can use fuel to extend its range doesn't mean it has to.

If anything it is a more qualified EV.

The Prius can not operate at highway speeds and travel for 40 miles with out consuming fuel and thus would not be a full EV. The Volt however can.
