Default GM says new Volt to get 230 mpg in city driving

Quote:
WARREN, Mich. – General Motors Corp. said Tuesday 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.

The Volt is powered by an electric motor and a battery pack with a 40-mile range. After that, a small internal combustion engine kicks in to generate electricity for a total range of 300 miles. The battery pack can be recharged from a standard home outlet.

GM came up with the 230-mile 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.

GM has produced about 30 Volts so far and is making 10 a week, CEO Fritz Henderson said during a presentation of the vehicle at the company's technical center in the Detroit suburb of Warren.

Henderson said charging the volt will cost about 40 cents a day.

"The EPA labels can and will be a game changer for us," he said.

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 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.

"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.

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, 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 nearly 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.



I guess Obama got his point across about America not falling behind to foreign Car company's cause they've been working hard lol
