During the 2013 NAIAS preview, Raj took the opportunity to respond to CR's claims on EPA hybrid mileage, 8:00 minutes in at livestream.com/ford. Meanwhile, CR has backpedaled and suddenly discovered how the C-Max and FFH earned the EPA mileage that they did. CR realized that the CR test isn't the same as the EPA test. Raj has a great powerpoint graphic that shows CR's city testing revealed that the Prius and Prius C diverged from the EPA city rating more than any other hybrid models, a "whopping" 19mpg in the case of the Prius. The Ford hybrids diverged 12 mpg, the Prius divergence was more than 50% worse. http://livestre.am/4g1wl
Consumer Reports today: "Ford should be congratulated for producing some of the most fuel-efficient vehicles on the market. However, customers who look for 47 mpg may need to readjust their expectations. When the EPA revamped its testing cycles in 2007, it made significant strides in bringing its estimates more in line with what drivers can expect to get themselves. The EPA is looking into this latest discrepancy and may again need to address new challenges in predicting fuel-economy for emerging technologies.
