Real world MPG not even close to Ford's Hybrid EPA MPG claims

CleanMPG's head-to-head test of Ford and Toyota's hybrids: Ford’s 47 mpg City/Highway/Combined Hybrid Ratings Ring Hollow - CleanMPG Forums

The real kicker is the steady-speed test. Real world cruise control test shows the C-Max falling short of the V and well short of the standard Prius.

Fuelly.com shows an even bigger discrepancy (and a much larger sample size).

Prius V:





C-Max:

Wonder why the EPA rating image Mechman600 posted shows 42 MPG combined, but the one Daox posted shows 43 combined...

On the same topic:

Most following this thread are probably aware Ford released a software update for the C-Max hybrid meant to help it get better "real world" mileage. Among other things, it increased the speed at which the car could drive with the ICE off.

Now we learn they've also been modding the physical car itself. 2014 versions ...

• include a "more efficient" ratio for the final drive,
• updates to reduce aerodynamic drag from the hood seal, tire air deflectors, windshield-pillar moldings, and tailgate.
• Ford will also use lower-friction engine oil in 2014 C-Max Hybrids.

Having all of a week under my belt with a fully broken-in C-max, pre-PCM upgrade, I find it easy to get 50 mpg as long as I stay off the highway. Most of the car's early life was with a "conventional" driver and most of its recent usage on interstates, so lifetime mileage is 38.2, consistent with many reports.

The analysis of the physical system shows the vehicle is larger cross-section, heavier, with more ICE displacement, but with the next generation of batteries and presumably some degree of technology advantage over an older design. In some usage modes, it may have a FE advantage, but it won't happen very often...

I like recumpence's POV....
"So, I am driving the way this car shines best... that is precisely why I bought this car. It has the perfect amount of interior space, is quite powerful, and excels at exactly what I need from it, mainly town to town driving."

And I like the moderator replies to radioranger... it's a better place this way.

HAve fun,

I'd really like to drive one and just see what the difference is between it and a Prius.
