# GM's Figure of 230MPG For The Volt Was Wrong

Posted on 11

Remember when GM claimed that the Volt could get around 230 miles per gallon? Well, think again. It was calculated using a government formula that never got final approval.

"We just don’t know right now" what the new number is likely to be, Micky Bly, executive director of global electrical systems for GM, said Wednesday at GM’s battery factory in Brownstown, Mich.

The Volt is an electric car and we’re sure most of you already knew that. It can go 40 miles on its batteries alone, but it also has a gas engine that is used like a generator. To find out the mileage for that would take a mathematician and the government doesn’t appear to have one.

The gas engine’s mileage is dependent on how charged up the battery is, which can vary based on each car’s charge. The Society of Automotive Engineers is currently working on a way to calculate mileage stuff for plug-in hybrids and electric cars. The organization expects the government to use its new standard for all future plug-in vehicles.

Lesson learned from this issue: never released an information that is not accurate; otherwise, it will create confusions on the public. This is a perfect example of rushing things that doesn’t get any proof basis. Are you still willing to drive this one? Absolutely, NOT.

well to be honest, what was an over speculations. By operating the Volt the way as I have described, it’s impossible to give a single number mpg.

So the Volt is getting 5 miles per kWh in city and in highway driving according to GM testing, or 4 miles per kWh according to EPA combined test cycle.

so what’s the real MPG rate of the volt?

hey just exaggerate it too much, it’s just recent that they develop a 65MPG system.

i guess they over estimate the capabilities of the chevy volt.

Well am happy to see that, another Prius beating car, but the rating system does seem a little arbitrary. Also, the wheels seems really not
appropriate on that concept, its too small,

The 230 mpg figure was wrong? Gee, you think?

The issue for me, and most others out there is "range," and not so much "mpg." Also, "charging time" is critical. In fact that will be the deal-killer for most people.

This article seems like a bit of an over reaction. The calculation was correct, just the government takes a while to approve things and never moves as quick as industry does. So technically we don’t really know if this figure will be considered too high or too low yet. And since it all depends on the batteries charge level it seems you would need to have 2 sets of mileage, one on just battery power and then the other assuming the battery is completely drained.
