DETROIT (Reuters) – Ford Motor Co’s C-Max and Fusion hybrids fell about 20 per cent short of its fuel economy claims, Consumer Reports magazine said, after running real-world tests on both models.The influential magazine said the Fusion hybrid delivered a 39 miles per gallon both on the highway and in city driving, while the C-Max hit a combined 37 miles per gallon. Both models were expected to command about 47 miles per gallon, according to estimates from Ford and the Environmental Protection Agency.
“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 web site.
Driving aggressively and other factors can undercut the fuel economy estimated by the EPA. In a statement, Ford said C-Max and Fusion hybrid drivers reported a range of fuel economy figures, including some that surpassed 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.
But Consumer Reports said among current models, more than 80 per cent of the vehicles it tested were within two miles per gallon of the estimates. The Fusion hybrid fell short by 8 miles per gallon, while the C-Max was off by 10 miles per gallon.
The Fusion hybrid still has the best fuel economy of any family sedan tested by Consumer Reports. The C-Max hybrid is second behind Toyota Motor Corp’s Prius V.
“Make no mistake; both the Fusion Hybrid and C-Max Hybrid still deliver excellent fuel economy,” Consumer Reports said. “But our tests show that buyers shouldn’t expect the stellar 47 mpg that Ford is promoting.”
The review comes a little more than a month after an EPA investigation showed that Hyundai Motor Co and its affiliate Kia Motors Corphad overstated their fuel economy by at least a mile per gallon.
Boosting fuel efficiency has been a pillar of Ford’s vehicle strategy for the past six years. This year the second-largest U.S. automaker expects to wind up with a record 11 per cent of the U.S. market for hybrid, plug-in hybrid and battery electric vehicles this year.
The Fusion, which competes in the bread-and-butter midsize sedan segment of the market, is a particularly important model for Ford. Earlier this year, Ford passed out T-shirts imprinted with the Fusion hybrid’s fuel economy figures at an event in New York with Chief Executive Alan Mulally to promote the Fusion.
Last week, the Fusion won the coveted Green Car of the Year award at the Los Angeles Auto Show.
