Volt Birth Watch 185: EPA Still Not Buying 230 MPG Number

Production of Chevy Volt “integration models” began last week, as Hamtramck tools up for final production of GM’s wundercar, but GM still isn’t saying anything about the car’s two most important features: the pricetag and EPA rating. The General has hemmed and hawed on the Volt’s price over the last several years of hype, but it hasn’t ever been shy about touting an “expected” 230 MPG rating. Because apparently it’s the EPA’s job to clear up GM’s misleading marketing claims. So what is the deal with that 230 MPG number, anyway?

Inside Line reports the latest on “negotiations” between GM and the EPA over the Volt’s testing paradigm and eventual MPG number.

“The 230 mpg number talked about a few months ago was based on some preliminary discussion with the EPA,” said Andrew Farah, the vehicle chief engineer on the Chevrolet Volt and Opel Ampera, when asked if the number is still relevant. “Those conversations have been continuing and have not yet come to a conclusion.”

After the media conference call, Inside Line asked Rob Peterson, GM’s Volt spokesman, if the Volt’s fuel economy is still up in the air.

“I couldn’t have said it any better,” he replied.

“The discussion continues to go on between the EPA and GM,” Peterson said. “[We’re] working together to come up with a number that works best for the consumer.”

Now, try to imagine the case for the 230 MPG number being a good thing for consumers. Sure, miles-per-gallon is the standard measure, but the idea that consumers will ever be able to drive 230 miles on one gallon of gasoline is simply laughable. But the Volt project has always started with a big eco-marketing number (it started with “40 miles without burning a single drop of gasoline”) with the car being built to suit. So, will the EPA stick to its guns? One thing is for certain: if the Volt goes on sale with a 230 MPG window sticker, the Government Motors conspiracy theorists are going to have a freaking field day. Especially considering that the Volt’s rating appears to come down to “negotiations” between GM and the EPA.

UPDATE: The Detroit News paraphrases Chief Engineer Andrew Farah as saying that “road testing shows the Volt is meeting its targets, including achieving a 40-mile range on batteries alone and the goal of 50 miles per gallon when the range-extending gasoline engine kicks in.”

    It's a simple "slap in the face" to the EPA's standardized test. Every vehicle is to follow this standardized test, given by the EPA, and the final mpg number is calculated. Over the years, the EPA standardized test for mpg has been criticized by the industry for not being applicable to real-world driving. By following the standardized test, with the Volt, and legitimately reporting the number (230 mpg), it forces the EPA to finally reconsider its standardized test. Since the Volt is so new in concept, and with the Leaf (among other electrics) coming to market, the EPA has to reevaluate its testing procedure for mpg and realize that there really is no such thing as a "standardized test" for all vehicles.

    To all those that think 230 mpg is too high: If I drive a Volt 30 miles a day for a year and never refill it, what is my mpg? The problem is not the number. It's the EPA thinking it needs a single number.

      A single number is good, if it's the right number. Problem is that the EPA is the wrong part of government. Protect the environment by buying a car full of batteries that moves the pollution from 10 feet behind me to a power plant 10 miles away? Please... I want a single #. "Total Cost per mile" Include depreciation, unplanned maintenance based on history of the vehicle, insurance costs, gas, routine maintenance based on the owners manual, tires, brakes, etc. Anyone of us could build the spreadsheet in an hour and would just need some raw data from Consumer Reports run the model.

  • Ltcmgm78 It depends on whether or not the union is a help or a hindrance to the manufacturer and workers. A union isn't needed if the manufacturer takes care of its workers.
  • Honda1 Unions were needed back in the early days, not needed know. There are plenty of rules and regulations and government agencies that keep companies in line. It's just a money grad and nothing more. Fain is a punk!
  • 1995 SC If the necessary number of employees vote to unionize then yes, they should be unionized. That's how it works.
  • Sobhuza Trooper That Dave Thomas fella sounds like the kind of twit who is oh-so-quick to tell us how easy and fun the bus is for any and all of your personal transportation needs. The time to get to and from the bus stop is never a concern. The time waiting for the bus is never a concern. The time waiting for a connection (if there is one) is never a concern. The weather is never a concern. Whatever you might be carrying or intend to purchase is never a concern. Nope, Boo Cars! Yeah Buses! Buses rule!Needless to say, these twits don't actual take the damn bus.
  • MaintenanceCosts Nobody here seems to acknowledge that there are multiple use cases for cars.Some people spend all their time driving all over the country and need every mile and minute of time savings. ICE cars are better for them right now.Some people only drive locally and fly when they travel. For them, there's probably a range number that works, and they don't really need more. For the uses for which we use our EV, that would be around 150 miles. The other thing about a low range requirement is it can make 120V charging viable. If you don't drive more than an average of about 40 miles/day, you can probably get enough electrons through a wall outlet. We spent over two years charging our Bolt only through 120V, while our house was getting rebuilt, and never had an issue.Those are extremes. There are all sorts of use cases in between, which probably represent the majority of drivers. For some users, what's needed is more range. But I think for most users, what's needed is better charging. Retrofit apartment garages like Tim's with 240V outlets at every spot. Install more L3 chargers in supermarket parking lots and alongside gas stations. Make chargers that work like Tesla Superchargers as ubiquitous as gas stations, and EV charging will not be an issue for most users.
