Reporting sales-weighted Corporate Average Fuel Economy (CAFE) on a monthly basis is apparently too confusing for consumers. Therefore, Hyundai has to decided to add in some more accurate fuel economy numbers to the monthly mix.

Starting with the posting of its September U.S. sales results, Hyundai threw in average window-label fuel economy results, becoming the first-ever automaker to disclose this data. Here's Hyundai's reasoning behind giving out the additional data points:
CAFE fuel economy is based on data from fuel economy tests and does not include adjustments taken to reflect real-world driving conditions. These are used to set federal standards. Average window-label fuel economy is what is shown on the vehicle window sticker. It is calculated by taking data from fuel economy tests and applying adjustments which results in ratings that more accurately reflect what drivers will get in real-world driving.
And judging by the discrepancy between the two sets of numbers, we'd agree that window-label results are far more useful to consumers than the near-meaningless CAFE numbers. From here on out, Hyundai will publish its monthly sales results with both sets of fuel economy data points. Which automaker(s) do you reckon will be next?

HYUNDAI BUILDS ON ITS INDUSTRY-LEADING FUEL ECONOMY REPORTING

COSTA MESA, Calif., Oct. 4, 2011 – With yesterday's September sales press release, HyundaiMotor America has begun disclosing both its sales-weighted Corporate Average Fuel Economy (CAFE) results and its average window-label fuel economy results. Hyundai is the first automaker to disclose either of these important fuel economy data points.

"At the beginning of the year, we began reporting monthly sales-weighted Corporate Average Fuel Economy (CAFE) results, to allow journalist, policy-makers, and consumers the ability to judge our progress against the evolving CAFE standards," said John Krafcik, Hyundai Motor America's president and CEO. "Now, we are going one step further and sharing average window-label fuel economy results, so stakeholders can better understand the very real difference between these two metrics."

CAFE fuel economy is based on data from fuel economy tests and does not include adjustments taken to reflect real-world driving conditions. These are used to set federal standards. Average window-label fuel economy is what is shown on the vehicle window sticker. It is calculated by taking data from fuel economy tests and applying adjustments which results in ratings that more accurately reflect what drivers will get in real-world driving. Each month Hyundai will provide both sets of data to ensure that journalists, policy-makers, and consumers understand the significant differences between CAFE standard fuel economy values and real-world fuel economy values.

"CAFE values, since they are unadjusted for real-world driving conditions, are more than 30 percent higher than the real-world adjusted fuel economy values shown on new car window stickers," said Krafcik. "It's important to continue to make this point so the dialogue around fuel economy standards, which are based on CAFE values and not real-world values, can be put into the appropriate context."
