Jeff Alson, senior EPA engineer, expects that more audits will be done in the future to ensure that automaker fuel consumption claims are accurate and the agency will continue to evaluate the best way to educate consumers on how fuel-economy ratings are established.
Ford is currently under fire for its mpg claims on several of its hybrid vehicles, including the C-Max Hybrid. Some owners are complaining that it doesn’t come close to achieving the 47 mpg it advertises. Currently, the U.S. government wants to raise fuel economy targets to 54.5 mpg by the end of the 2025 model year, and Alson expects that to remain the case.
“Everybody wants a label that tells you exactly what you’re going to get, but obviously that’s not possible,” Alson said. “A good general rule of thumb is that real-world fuel economy is about 20 percent lower than the lab numbers.”
