Consumer Reports Said Ford's 47 mpg claim is too high for both vehicles

There are questions regarding Ford's C-Max Hybrid and Fusion Hybrid's advertised 47 mpg, and the U.S. Environmental Protection Agency (EPA) intends to check it out.

Ford's C-Max Hybrid and Fusion Hybrid both show an estimated 47 mpg, but Consumer Reports recently pointed out that neither are living up to the automaker's claims. According to its testing, the C-Max Hybrid received 35/38/37 mpg for city/highway/combined. For the Fusion Hybrid, it found 35/41/39 mpg for city/highway/combined.

"Yes, the disclaimer on EPA fuel-economy labels notes that your results may differ," said Consumer Reports. "But the overall mpg for these C-Max and Fusion models is off by a whopping 10 and 8 mpg, respectively, or about 20 percent. Our overall-mpg results are usually pretty close to the EPA's combined-mpg estimate. Among current models, more than 80 percent of the vehicles we've tested are within 2 mpg."

Ford responded to the claims, saying that mileage varies among hybrids.

"Early C-Max Hybrid and Fusion Hybrid customers praise the vehicles and report a range of fuel economy figures, including some reports above 47 mpg," said Ford spokesman Wes Sherwood. "This reinforces the fact that driving styles, driving conditions and other factors can cause mileage to vary."

While all vehicles must undergo the EPA test for fuel efficiency, the test isn't actually administered by the government agency. Instead, automakers perform the test and the EPA reviews it. In many cases, factors like temperature and speed result in gas mileage being lower than the EPA sticker.

Ford's testing found 47 mpg overall for both vehicles, and while it's common for the EPA to review such claims and discover a variation in gas mileage, Consumer Reports complained that this is a pretty big gap between Ford's findings and its own.

The EPA said it will "look at the report and data."

Back in December 2011, Consumer Watchdog called on the EPA to investigate Hyundai over its fuel economy claims. Hyundai claimed that its Elantra achieved 29 MPG in the city and 40 MPG on highway. However, the organization received a higher-than-usual number of complaints that real-world mileage was in the mid-20 mpg range.

From there, the EPA investigated Hyundai for misleading mileage claims and found that the fuel economy estimates of most of its 2012-2013 models were inflated. The same goes for Kia. Both Kia and Hyundai will be lowering the fuel economy estimates on the majority of their 2012 to 2013 models after EPA testing discovered a gap between its data and what both of the companies are claiming.

Hyundai and Kia admitted to overstating the estimated fuel economy on window stickers of about 900,000 vehicles sold since late 2010. Reports show that Hyundai alone could spend $100 million trying to fix the fiasco.

The C-Max doesn't come with a spare tire, or even have space for one. Just a can of flat fix.
I'd never buy a car without a spare tire, as I would have been stranded too many times over the years.

Yes !
Cars are now being sold WITHOUT SPARES, just to reduce weight to INCREASE mpgs. Simple.

And what will half of the car buyers do - buy a spare and put it in the trunk, thus making sure they can't get the EPA window sticker mpg number!

See how those numbers mean nothing!

But in your world those numbers are set in stone, never to be had a finger pointed at! PLEASE !!!!!! It's car mpgs. It's not about our health, of the safety of astronauts, or something really important.

The weight of a full spare tire equates to noise on mpg numbers. It doesn't affect highway mileage (weight has no factor) and would almost be imperceptible on the city mileage. If you really think a 50lb weight affects the readings, its well under what the average fat American is already carrying around their waist anyway.

Red Herring #1

Then half of car buyers throw a spare tire in. Really. Bet that number is actually less than 1%.

Red Herring #2

Finally, you still don't get it. EPA numbers have nothing to do with real world usage. That part I think you get. But they play an important role as a controlled baseline. That's the part you completely miss.

That's the basics of scientific measurement. You need a control. Without a controlled baseline, all further measurements are meaningless.

The EPA numbers give a consumer an idea of how different vehicles will perform over the EXACT same conditions. While they don't mean you'll get those exact numbers, they should be close. And when comparing, one car that gets 5mpg better than another model should get somewhere close to that same gap in real world usage.

And the final part you still don't get. If you're going to spend the money to mandate the test, you need to spend the money to enforce the test results. Simple concept.

And again, you seem fixated that I have some obsession with the EPA numbers as a real world fact. Not true. But I see their value as a measurement tool, nothing else. And when I'm measuring something, it better damn sure be equal from ruler to ruler.

More scare tactics.

Guess what, there's ton's of cars being sold without spares. Not the end of the world.

Runflat tires let you get to where you need if you have issues. Tire monitoring systems let you know if you have a flat rather than damaging a non-runflat tire. Etc, etc.

The spare tire is less about EPA numbers and more about having to design around a spare tire area, adding cost, and weight reduction, which helps.

So you'd never buy a car without a spare. Guess you're going to miss out on all the fun cars coming out. Myself, I've been quite happy with my Corvettes.
