Chevrolet Volt
General Motors' all-electric Volt to reach consumers in late 2010

General Motors is quite confident these days. The company recently priced its highly-anticipated full-size hybrid SUVs and showed off a concept version of its full-size hybrid Chevrolet Silverado. GM CEO Rick Wagoner also noted that his company will release one hybrid per quarter for the next four years -- lofty goals indeed.

Likewise, the company's brand new Chevrolet Malibu mid-sized sedan has been generating an overabundance of praise and its new $32,000 second-generation Cadillac CTS just walked away with Motor Trend's Car of the Year award.

GM is hoping to use this momentum and high level of interest in its vehicles to push the electric motor-powered Chevrolet Volt to customers by the end of 2010.

GM vice chairman Bob Lutz has heard all of the critics who question GM's aggressive ramp for the Volt, but is still committed to moving forward.

"There is a lot of skepticism within the company about the timeline," said Lutz. "People are biting their nails, but those of us in a leadership position have said it has to be done."

GM is hoping to use the Volt as a halo car to further strengthen its brand and its commitment to fuel economy. Dodge used the Viper to enhance its image for performance and styling in the 1990s. Toyota used its Prius at the turn of the century to shroud the entire company with a green image despite the fact that gas guzzlers like the Tundra and Sequoia share the same showroom space.

"When they think of GM, the iconic brand is, unfortunately, the Hummer," continued Lutz. "That perception needs to change.

The GM Volt features a 1.0 liter, 3-cylinder gasoline engine which is solely used to recharge the onboard lithium-ion battery pack. The battery pack, which will be manufactured by Compact Power and Continental Automotive Systems, powers the Volt's electric motors for forward propulsion.

GM says that the Volt can travel for up to 40 miles on battery power alone. After the 40 mile threshold has been reached, the gasoline engine kicks back in again to recharge the battery pack.

The entire industry has its eyes on GM and its Volt. Toyota took a big risk with its Prius and it has paid off dearly for the company.

"We have since realized that letting Toyota gain that mantle of green respectability and technology leadership has really cost us dearly in the marketplace," Lutz added. "We have to reestablish GM's leadership and the Volt is, frankly, an effort to leapfrog anything that is done by any other competitor."

The small electric generator on this vehicle can run at a constant RPM keeping the design very simple and efficient. The estimate from GM is that it should get 50mpg on the gas generator, which is quite exceptional, especially when considering that it has a 160hp electric motor driving the wheels.

As for you 55mpg vehicle, that is most certainly NOT modest! That mileage is not matched by ANY current production vehicle in North America (the Prius at 46mpg is the best available). Is that a European model? And if so, are you talking diesel or gasoline? US gallons or imperial gallons?

As a bit of a side note to this, the small generator in the Volt would be OUTSTANDING as a diesel generator rather than gasoline.

Was thinking the same thing about using a diesel generator instead. Typical GM thinking however using the gasser instead of using diesel. Even Neil Youngs biodiesel/hybrid project will get better mileage.

55mpg is not that uncommon, the OP might have a Insight or a VW TDI (I own TDI.) Even biodiesel conversions have been getting around 60mpg. The Mini Cooper D (UK) gets around 70mpg (imperial gallons).

Yes, there are very exciting things to come with diesel/hybrid cars.

In North America it is!

The North American VW TDI (1.9L 4 cylinder on the Jetta, Golf and Bug) gets 33mpg on the new EPA test or 38mpg on the old test. The Mini Cooper D doesn't exist on this side of the pond, only the gasoline version. The Insight is the only mass-produced car sold here that could manage 55mpg+ in recent times, and it's been discontinued.

Keep in mind that that we're talking about U.S. gallons and not imperial gallons (1 US gallon ~= 0.8 imperial gallons). Also remember that even the old EPA fuel economy test was more stringent than the U.K. rating system.

Getting 50 miles to the U.S. gallon is definitely NOT the norm here and while it might happen in Europe sometimes, I'd challenge anyone to find a mass-produced car anywhere in the world that gets that fuel economy off gasoline with a 160hp engine.

1. There is a whole world outside of the US, hope you are not just realizing that now. Typical American thinking! Just because the US doesn't offer it means it can't be done? My original post was to show 55mpg was not using some exotic experimental car but ones that were purchased off the shelf.

2. While I might come across as biased since I own a 06 TDI Jetta, all of VW TDIs are well recognized by actual owners for consistently achieving better than government tests for 2006. Our record with mostly highway driving is 54.3mpg and we average 44mpg combined since owning (23,000 in one year with 75% highway). That calculator on the website just takes the numbers and reduces them by an estimated percentage. Why would the government test a car in 2007 when it wasn't produced that year?

3. When the new VW TDIs come out, current road tests have shown them achieving 65mpg on the highway in the US.

I'm well aware that there IS a world outside of the U.S. and in fact I'm not even American and have lived in Europe.

Of course better than 55mpg CAN be done, but these cars don't generally sell to North American customers, and that's who this Chevy Volt is going to be marketed towards. It doesn't matter that a Peugeot 106 diesel can get better mileage because the two are unlikely to even sell in the same country, let alone directly compete against one another.

Last I heard GM was considering Hydrogen/Gasoline/Ethanol/Flex-Fuel/Diesel generators. That's the beauty of serial hybrids - they're much more modular in this respect than parallel hybrids.

It may be true that no production car is EPA rated at 55 MPG, except maybe the Insight, but I haven't looked at the new rating for that vehicle. What you need to realize though is that while the new EPA tests are more rigorous to match what drivers actually get, that's not how someone should drive to begin with. I'm sorry that my old model Prius, 2002 model, can beat the old EPA ratings on the new Prius, 60 MPG, but it can. 55 MPG may be pretty uncommon in general, but with the Prius and Insight it's pretty average unless you drive like the new EPA tests. I've seen mileage as low at 35 MPG in a Prius, not mine, but I've also seen over 90 on a Prius, lifetime average. I'm sure, more like hoping, that at least some of you have seen the world records for the highest MPG in a production car. They've driven an Insight over 2000 miles in one tank of gas and the world record for MPG is like over 150 MPG on a non-modified mass produced vehicle.

The numbers I get are only uncommon for those who drive like dumbasses and race to red light. If patience is a virtue then less than 1% of the American drivers have it.

Lets make a big realization here, some people are speaking imperial gallons and others are speaking US gallons which are very different measurements.

55mpg Imp = 45.8mpg US
55mpg US = 66mpg Imp

The Prius is slated around 41mpg (US) real world average with high mpg around 54 and low at 31. This is with EPA estimate of 60 City and 51 Highway (all US measurements).

Taken from here:
and US/Imp gallon conversions from here:
