Is this just the tip of the iceberg? Fyidriving.com hears that Hyundai’s recent woes with its fuel-economy claims on certain models could possibly extend to other automakers and might even change the way these tests are conducted. The buzz around the Los Angeles International Auto Show that wraps up Dec. 9 is that others are busy checking and rechecking their numbers to ensure they would hold up if the U.S. Environmental Protection Agency were to audit their results. (Each manufacturer tests its own vehicles, according to the EPA’s prescribed method). Particularly worrisome are the numbers claimed by a number of gas-electric hybrid vehicles that appear to be less than real world. Our source thinks that, should other companies be forced to do an about-face on their vehicle’s fuel ratings, the process might very well wind up being handled by an outside, independent testing firm, or possibly the EPA itself.
