2011 Chevy Volt - Click above for high-res image gallery

Apparently, we're not the only ones trying to figure out the exact methodology that was used to determine the supposed 230 mile per gallon city rating claimed by General Motors for the upcoming Chevy Volt. In response to a query from the boys at Green Car Advisor, the EPA issued the following statement:
EPA has not tested a Chevy Volt and therefore cannot confirm the fuel economy values claimed by GM. EPA does applaud GM's commitment to designing and building the car of the future - an American-made car that will save families money, significantly reduce our dependence on foreign oil and create good-paying American jobs. We're proud to see American companies and American workers leading the world in the clean energy innovations that will shape the 21st century economy.
Although it deserves noting that GM CEO Fritz Henderson didn't exactly say the 230 mpg rating was an official figure from the EPA, it sure is being bandied about as if it were gospel in the huge marketing campaign launched ahead of today's announcement.

When contacted for comment, GM told AutoblogGreen that the EPA is not backing away from the 230 numbers and that it's unlikely that the EPA will come out with a much lower number when they actually get to run a Volt through the official cycle. Further, GM believes that coming out with the 230 rating at this point in time is one way to change people's perception of what kind of car the Volt is.

      GM didn't lie about the number, but it's misleading as people who won't read the fine print (which I suspect would at least be half) won't figure out that that figure drastically dwindles when you drive more than 50 miles.

      I never saw the economic value of this car. Environmental, maybe. Ecological, questionable (those giant batteries aren't the most ecologically friendly to make nor to dispose). If you wanted affordable fuel economy, you'd just get a Golf TDI at likely half the price--and you don't need to restrict your driving to under 50 miles to get the fuel economy, either.

        Once again... at the end of their life the batteries do not need to be "disposed" they will be recycled into new batteries. It is not the toxic catastrophe that people often make them out to be.

      GM only said they applied EPA's methodology. Ant, of course the EPA isn't going to vouch for a vehicle they haven't gotten their hands on yet.

      I'll agree its a silly approach. But not enough negativity in the last thread, so we need to recast it to imply something devious on GM's part? Like implying they claimed the EPA certified it when it never made that claim?

      Traffic not good enough?

      stupid volt haha!!

      well, GM is designing the car, not the EPA. I think they would know how efficient the engine is,

      FAAAAAAAAAAAAAAAAIIIIIIIIIIIIIIIIIIIIIIIIIIIILLLLLLLLLLLLLLLLL

      lift it up higher so it falls harder right? =/

      ...and then get Obama to pass a huge "plug-in"/Low emissions credit for Volt purchases to once again pay people to buy cars

      wtf is wrong with this picture?...I hope im wrong

      im just gonna go toke a up a bit more

      This sounds as only a PR stunt. They do not have a pre-production model to prove it. I think this only is achieved when the car is pulled by two horses.

      At least it got GM a lot of publicity.

      The EPA never denied that the Volt will attain those numbers; they simply haven't gotten a hold of one yet to verify the test.

      Q: How many miles per gallon will the Chevy Volt get?
      A: A bit of a trick question. For the first 40 miles it will get infinite mpg, because no gas will be burned. When the generator starts, the car will get an equivalent of 50 mpg thereafter. One can calculate the average mpg per for any length drive starting with a full battery: Total MPG = 50xM/(M-40)

      It's really, really simple, guys! Plug the formula into Microsoft Excel and punch in any distance in miles to find the fuel economy for the trip. The lowest the mpg will get is at the full range of 300 miles, in which case it averages 57.7 mpg. For more realistic distances for daily driving situations, like 50 miles, it gets 250 mpg. Either way, the car is still incredibly efficient!

      Punch in your trip odometer tomorrow morning on the way into work and see how much you drive. Then plug that number into the equation and see how high your fuel mileage would be if you were driving a Volt.

      GM is just Pathetic!
      • 5 Years Ago
      I don't have high hopes for this car and I think it is just ludicrous to announce an MPG of 230.
      Why not put out something more reasonable like 60-70 which sounds more believable and then if it gets higher, bonus.

      More lies from Government motors what a surprise first get the car on the road before you spit out more BS, GM. What is it 2012 when it finally hits dealership lmao.
