slashdot - "General Motors, emerging from bankruptcy, today announced that its upcoming plug-in hybrid vehicle, the Volt, will have an EPA rating of 230 mpg for city driving (about 98 km/L). The unprecedented rating, the first in triple digits, is the result of a new (draft) methodology for calculating the 'gas' mileage for vehicles that operate primarily or extensively on electricity. The Volt, due out late next year, can drive approximately 40 miles on its Li-Ion battery pack, after which a gasoline engine kicks in to provide additional electricity to charge the battery. Running off the gasoline engine yields approximately 50 mpg. Of course, the devil's in the details, because the conversion of grid-based electricity to gasoline-mileage is imprecise."
Math hurts, as it is reality based- Haase
Update:
CNN agrees with Haase?
You won't save enough on fuel costs to compensate for the likely higher sticker price.
And then the truth comes out:
GM admits Volt doubts
General Motors has cast doubt over the long-term future of the Chevrolet Volt by claiming it may not be commercially viable and other rivals may overtake it with superior and more advanced technology.GM submitted a regulatory filing report to the US Treasury yesterday and CEO Fritz Henderson claimed its “disclosures are consistent with our commitment to remain transparent and to keep the public informed of our progress”.
