GM says Volt to get 230 miles per gallon in city

In this Wednesday, Aug. 5, 2009 file photo, Vice President Joe Biden looks over a Volt concept vehicle after addressing an audience in Detroit. General Motors Corp. said Tuesday, Aug. 11, 2009 that its Chevrolet Volt rechargeable electric car should get 230 miles per gallon of gasoline in city driving, more than four times the mileage of the current champion, the Toyota Prius.
DETROIT General Motors Corp. said Tuesday its Chevrolet Volt rechargeable electric car should get 230 miles per gallon (98 kilometers per liter) of gasoline in city driving, more than four times the current champion, the Toyota Prius.
GM came up with the figure in early tests using draft guidelines from the U.S. Environmental Protection Agency for calculating the mileage of extended range electric vehicles, said Tony Posawatz, GM's vehicle line director for the Volt.
If the figure is confirmed by the EPA, which does the tests for the mileage posted on new car door stickers, the Volt would be the first car to exceed triple-digit gas mileage, Posawatz said.
The Volt is powered by an electric motor and a battery pack with a 40-mile (65-kilometer) range. After that, a small internal combustion engine kicks in to generate electricity for a total range of 300 miles (480 kilometers). The battery pack can be recharged from a standard home outlet.
Most automakers are working similar plug-in designs, but GM could be the leader with the Volt, which is due in showrooms late in 2010.
Toyota's Prius, the most efficient car now sold in the U.S., gets 48 miles per gallon (20 kilometers per liter) of gas. It is a gas-electric hybrid that runs on a small internal combustion engine assisted by a battery-powered electric motor to save gasoline.
The first-generation Volt is expected to cost near $40,000, making it cost-prohibitive to many people even if gasoline returns to $4 per gallon. The price is expected to drop with future generations of the Volt, but GM has said government tax credits and the savings on fuel could make it cost-effective, especially at 230 miles per gallon (98 kilometers per liter) .
"We get a little cautious about trying to forecast what fuel prices will do," Posawatz said. "We achieved this number and if fuel prices go up, it certainly does get more attractive even in the near-term generation," he said.
GM was to present details of the mileage figure on Tuesday morning at an event at its technical center in the Detroit suburb of Warren.
Figures for the Volt's highway and combined city/highway mileage have not yet been calculated, Posawatz said. The combined mileage will be in the triple digits as well, he said, but both combined and highway will be worse than city because the engine runs more on longer highway trips.
The EPA guidelines, developed with input from automakers, figure that cars like the Volt will travel more on straight electricity in the city than on the highway. If a person drives the Volt less than 40 miles (65 kilometers), in theory they could go without using gasoline.
The mileage figure could vary as the guidelines are refined and the Volt gets further along in the manufacturing process, Posawatz said.
GM is about halfway through building about 80 Volts that will look and behave like the production model, and testing is running on schedule, Posawatz said.
Two critical areas, battery life and the electronic switching between battery and engine power, are still being refined, but the car is on schedule to reach showrooms late in 2010, he said.
GM is simulating tests to make sure the new lithium-ion batteries last 10 years, Posawatz said.
"We're further along, but we're still quite a ways from home," he said. "We're developing quite a knowledge base on all this stuff. Our confidence is growing."
The other area of new technology, switching between battery and engine power, is proceeding well, he said, with engineers just fine-tuning the operations.
"We're very pleased with the transition from when it's driving EV (electric vehicle) to when the engine and generator kick in," he said,
GM also is finishing work on the power cord, which will be durable enough that it can survive being run over by the car. The Volt, he said, will have software on board so it can be programmed to begin and end charging during off-peak electrical use hours.
Chrysler LLC, Ford Motor Co. and Daimler AG are all developing plug-ins and electric cars, and Toyota Motor Corp. is working on a plug-in version of its gas-electric hybrid system. Nissan Motor Co. announced last month that it would begin selling an electric vehicle in Japan and the U.S. next year.

How is GM going to sell a $40k car? My guess is, an enormous federal subsidy for buying any car fitting the exact description of a Volt. Wait for it...

Any specification of fuel MPG in a plug-in hybrid is VERY misleading and quite silly. If the Volt can get 230MPG, then a Tesla is guaranteed to get (infinity symbol)MPG. That said, it's still a pretty cool car!

thekid3477... a standard Prius derives ALL of its energy via its internal combustion engine. In any non-plugin hybrid vehicle, the electric portion of system is nothing more than a giant flywheel --storing energy generated by the internal combustion engine for later release at a more convenient time. Any stored kinetic energy used to recharge the batteries via braking was originally stored by accelerating the Prius under power of its internal combustion engine and all of the energy stored in its batteries was originally stored in the form of gasoline.
Energy out can never exceed energy in. So, if a hybrid doesn't have an electric plug, solar panel, wind turbine, etc, then ALL of its stored energy must come from its only available source(s) of input. In this case, gasoline.

Hey Andy:
Ever hear of a little conflict called the Revolutionary War? Do you buy anything British? How about the Civil War? The Battle of Gettysburg alone cost more lives than nearly 5 Pearl Harbors. If you’re from the South, do you buy anything made in the North, or vice-versa? How about the Korean War? The PRC was a huge backer of the North Koreans. Many US lives were lost in that conflict. Do you buy anything made in China? Take off the blinders and learn some history. Wow.

gary the prius does not 'get all of its energy from burning gasoline and converting it into electricity'. there is a gas motor and an electric motor on the yota prius and the honda insight. the electric motors are powered by battery packs that are re-charged by the energy created from braking. BOTH vehicles WILL operate on electricity only at lower(in town) speeds, burning ZERO drops of gasoline.

Warcraft; sure I'll answer that for MrBlack - Ever heard of Cap & Trade? Why do you think this was shoved down our throats so quickly. They know that with the standards being set so high on automobiles, gas consumption will drop & they NEED every penny of tax revenue they get from it - so they increase something else - oh, and just wait, the price will come down - way down - just wait - the next program will be to lower the cost of the electric cars so everyone can buy 1 & the Gov't will own the batteries & you will "lease" them (yes, another tax thats not called a tax).Try this link:

Its only a matter of time, look at OK, they already want to impose a surcharge on miles driven NOT consumption of gas.
Listen, all these standards & being green sound great but come on its NOT in the Governments best interest. Think about it.

I think it's great that the Volt is finally being rolled out next year. The obvious problem with this vehicle is the price tag. The economics simply don't work. It would make more sense to buy a $15,000 vehicle, and then have TWENTY FIVE THOUSAND DOLLARS (!) left over to spend on gas. Not to mention the fact that most people would finance the purchase, thus spending even more money on interest and fees.
But the economics will change in favor of the Volt if and when the sticker price falls, and as the price of gas continues to rise under Socialism.

GM was concerned much more about building these big vehicles (such the American way of doing things) than making changes (appeal, quality, and better gas mileage) to compete with Toyota, Nissan, and Honda. Foreign cars are not cheap but when you build a car than is going to last a while with no problems you can charge whatever you want.

We should all remember that electricity is not free and is not in unlimited supply. Does anyone know how much electrical power a plug in hybrid will consume? We need some sort of miles per kilowatt measurement. If everyone were to switch to electric, would we have the capacity in our power grid to supply that energy and what would happen to the cost if demand were to increase by that much? The price of all electricity will rise, not just what is used by cars and don't forget that most electricity is produced by burning fossil fuels.

The current Prius is not a plug in hybrid, but a gas powered hybrid. It gets all of its energy from burning gasoline and converting it into electricity. The Volt gets a large part of its energy from your wall socket and only uses gasoline when the batteries run low. It is quite possible that you could drive a Volt and not use any gasoline at all if you only made short low speed trips. The Volt is not getting 230 mpg from gasoline. Your Honda probably was probably lighter and probably had a smaller engine, maybe fewer emission controls. I'm just guessing on that one. I find the article misleading at best. Prius is coming out with a plug in hybrid this year and that is the one that should be used to compare with the Volt.

Jymontywi,
Too little too late. I personally hope the volt is very successful. At $40K+ how many unemployed GM line workers will line up to buy one? Will the GM employee discount apply? Probably not. Unfortunately, GM is late to the dance, even Obama owns a Ford Escape hybrid.

"Toyota's Prius, the most efficient car now sold in the U.S., gets 48 miles per gallon (20 kilometers per liter) of gas."
I owned a 1992 Honda Civic that regularly got 45+ MPG. On one trip (all highway driving) I actually got 52 MPG. If a straight gas car built 17 years ago could get this kind of mileage, why can the hybrid Prius ONLY get 48 MPG????
