Ford fails to deliver on promised efficiency again

If you're a fan of green vehicles or are shopping for car promising lots of fuel economy, you may be familiar with the Ford C-Max Hybrid and the Toyota Prius V. These vehicles are two of the most popular hybrids in the segment. Ford has been at the center of allegations from several publications that had reviewed the C-Max claiming that the vehicle does not meet the fuel economy promised.

Previously, the EPA had stated that it was ready to investigate Ford over allegations of improperly stated fuel economy numbers for its C-Max and Fusion Hybrid. A recent test conducted of the C-Max Hybrid and the Prius V by reviewer Wayne Gerdes found that the Ford C-Max didn't achieve fuel efficiency suggested by the EPA's numbers.

The EPA shows that the C-Max gets 47 miles per gallon in all three EPA test categories (city/highway/combined). According to Gerdes, in his testing the C-Max managed only 35.537 miles per gallon over 360 highway miles. However, he does admit that in the city he was able to achieve 52 miles per gallon over 22.8 miles of driving, which is better than the EPA promises.

He also tested the Prius V along the same driving route and achieved 40.768 miles per gallon on the highway and 55.8 miles per gallon in the city. That means while the EPA lists lower numbers for the Toyota (44/40/42) compared to the C-Max, it actually outperformed the C-Max.

Gerdes isn't alone in finding that the Prius V posted better real-world efficiency numbers than the C-Max, Motor Trend came to the same conclusion during its tests.
As with any review that tends to focus heavily on miles per gallon for hybrid vehicles, you have to have a saltshaker ready. Driving style and conditions greatly affect fuel efficiency numbers for hybrid and electric vehicles. That means the results from one person won't necessarily be the same for the next.
However, real world numbers from fuel economy conscious C-Max and Prius V owners on Fuelly back up the claims that the former lags far behind its EPA numbers while the latter hits them right on the mark.

I owed a Prius for a short while, sold it because the seat hurt my back pretty badly. Now have a Mazda 6, the Prius was an absolute mistake that I will be paying for for quite a while, but at least the Mazda is worlds better in every way except gas mileage.

When I had the Prius it does get to you watching that mileage gauge, I actually wish cars did not have them, I had to force myself never to have it display.

I have a feeling the whole 'getting a hybrid' novelty might have blinded you to some of the things you would have normally been more critical about in other vehicles (I am most certainly critical of the comfort of the driver's seat!!).

For sure a Lexus is going to have a way more comfy driver's perch than a Prius :D

On the other side I owned a Mazda 6 (V6 GT Sport)before and dumped it about 2 years later due to its poor build quality (that didn't manifest until about owning for about a year) and super laggy engine. Seats were fine in it though.
