Earlier today Ford announced that it will reduce the stated fuel-economy rating of its C-Max Hybrid. Edmunds.com has been tracking this story closely ever since consumers on our forums complained late last year that the vehicle does not come close to the advertised 47 mpg.
Edmunds.com Green Car Analyst John O’Dell offers the following take:
“Ford wouldn’t take such a drastic step if it didn’t feel that it was absolutely necessary, even if it’s just a move to protect its image. Edmunds.com’s own testing found that the 47 mpg mark is achievable in the C-Max, but that was under controlled driving conditions. As we all know, our own driving styles rarely reflect the perfect behaviors needed to reach peak fuel economy. Additionally, hybrids perform best in slow, stop-and-go city traffic while for many people the daily drive is spent mostly on the freeways. These are two areas where the disconnect between EPA testing and real-world driving experiences come into play.”
Just last month Edmunds.com worked with KNBC in Los Angeles to test a C-Max Hybrid that one local couple claimed fell far short of its advertised gas mileage, and over the course of a 105-mile loop, Edmunds.com achieved a rate of over 50mpg.
