According to Consumer Reports magazine, the fuel claims for Ford’s Fusion and C-Max hybrids fell about 20% short.
Consumer Reports said that the Fusion offered 39 miles per gallon both on the highway and in city driving, and the C-Max delivered a combined 37 miles per gallon. But according to Ford and the Environmental Protection Agency’s estimates the models were supposed to achieve about 47 miles per gallon.
“These two vehicles have the largest discrepancy between our overall-mpg results and the estimates published by the EPA that we’ve seen among any current models,” Consumer Reports said in a blog post on its website.
Offering models with improved fuel efficiency was of utmost importance for Ford’s strategy over the past 6 years, as it expects to wind up with 11% of the US market for EVs by the end of this year. Ford, and other automakers are required to meet by 2025 the U.S. government’s target for corporate average fuel economy of 54.5 mpg, which means 36 mpg or higher in real world driving.
But fuel economy highly depends on aggressive driving and other factors. Several C-Max and Fusion hybrid drivers reported various fuel economy figures, including several over 47 miles per gallon.
“This reinforces the fact that driving styles, driving conditions and other factors can cause mileage to vary,” Ford spokesman Wes Sherwood said.
