Chevrolet Volt window sticker
93 mpg on battery power, 37 mpg on gasoline power

After a cluster bomb that was unleashed yesterday when the Nissan Leaf was rated for an EPA estimated 99 mpg -- even though it is a "battery only" vehicle -- General Motors is dropping a bunch of digits on us when it comes to the EPA rating for its Chevrolet Volt.

According to the window sticker that will be plastered on all new Volts sold in the U.S., the vehicle is rate at an equivalent of 93 mpg when running on electricity, and a more sedate 37 mpg when the gasoline engine kicks in after the battery is depleted. This two figures combined give the Volt a "composite" rating of 60 mpg.

And here are some more numbers -- the Volt will have an official "battery only" range of 35 miles, while the total driving range (taking into account the batteries and the gasoline tank) will be 379 miles.

When the Volt was first announced, GM said that the vehicle would have a 40-mile range when running on battery power. The company recently revised that figure to 25-50 miles.

The Volt will go on sale later this month with a price tag of $41,000 before a $7,500 federal tax credit.

Any electrical engineers out there?

I have a basic question following a known statement:

The electrical infrastructure of the US and Canada is old and has shown signs of inadequacy.

So here's the question: If people start buying these electric vehicles in great quantities, how much more electricity would be required of power plants to generate? Would the infrastructure be able to handle a much greater quantity of drain? As far as I can tell, we're talking a huge amount of electricity for each car. Anyone with sense care to comment on that?

The current grid can support 84% of all cars in the US since most charged at night. Power plants can not be shut off willy nilly so at night plants are running but little of the electricity produced is sold. Electricity rates should go down as more and more electricity is sold at night instead of wasted.

In the future with lots of electric cars plugged in power companies could use the cars batteries to handle peak loads instead of firing up small plants as they do now or store solar or wind excess power. Of course were a long way from that.

I don't know what powerplants you're talking about. Hell, I watched a show about how electrical engineers have to anticipate tea time in England to get the right amount of juice flowing through the pipes.

I know that demand drops, and the cost of energy at night is less than in the day. However, I am sceptical that your analysis is accurate.
