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.

  • Bkojote Allright, actual person who knows trucks here, the article gets it a bit wrong.First off, the Maverick is not at all comparable to a Tacoma just because they're both Hybrids. Or lemme be blunt, the butch-est non-hybrid Maverick Tremor is suitable for 2/10 difficulty trails, a Trailhunter is for about 5/10 or maybe 6/10, just about the upper end of any stock vehicle you're buying from the factory. Aside from a Sasquatch Bronco or Rubicon Jeep Wrangler you're looking at something you're towing back if you want more capability (or perhaps something you /wish/ you were towing back.)Now, where the real world difference should play out is on the trail, where a lot of low speed crawling usually saps efficiency, especially when loaded to the gills. Real world MPG from a 4Runner is about 12-13mpg, So if this loaded-with-overlander-catalog Trailhunter is still pulling in the 20's - or even 18-19, that's a massive improvement.
  • Lou_BC "That’s expensive for a midsize pickup" All of the "offroad" midsize trucks fall in that 65k USD range. The ZR2 is probably the cheapest ( without Bison option).
  • Lou_BC There are a few in my town. They come out on sunny days. I'd rather spend $29k on a square body Chevy
  • Lou_BC I had a 2010 Ford F150 and 2010 Toyota Sienna. The F150 went through 3 sets of brakes and Sienna 2 sets. Similar mileage and 10 year span.4 sets tires on F150. Truck needed a set of rear shocks and front axle seals. The solenoid in the T-case was replaced under warranty. I replaced a "blend door motor" on heater. Sienna needed a water pump and heater blower both on warranty. One TSB then recall on spare tire cable. Has a limp mode due to an engine sensor failure. At 11 years old I had to replace clutch pack in rear diff F150. My ZR2 diesel at 55,000 km. Needs new tires. Duratrac's worn and chewed up. Needed front end alignment (1st time ever on any truck I've owned).Rear brakes worn out. Left pads were to metal. Chevy rear brakes don't like offroad. Weird "inside out" dents in a few spots rear fenders. Typically GM can't really build an offroad truck issue. They won't warranty. Has fender-well liners. Tore off one rear shock protector. Was cheaper to order from GM warehouse through parts supplier than through Chevy dealer. Lots of squeaks and rattles. Infotainment has crashed a few times. Seat heater modual was on recall. One of those post sale retrofit.Local dealer is horrific. If my son can't service or repair it, I'll drive 120 km to the next town. 1st and last Chevy. Love the drivetrain and suspension. Fit and finish mediocre. Dealer sucks.
  • MaintenanceCosts You expect everything on Amazon and eBay to be fake, but it's a shame to see fake stuff on Summit Racing. Glad they pulled it.
