I received delivery of my 2013 C-Max Energi plugin hybrid ten days ago and have been enjoying it ever since.

Last week I posted my first early experience and compared it to longer term two year experience driving the Chevy Volt.  I offered to take your questions in the comments.

For the most part people were interested in fuel economy, so I will focus on that.

Recently there has been a lot of press surrounding the the fact the non plugin C-Max got lower mpg in Consumer Reports real world driving than the automaker reported.  Ford claims 47 mpg combined and CR found 37 mpg combined.

Ford claims 43 mpg combined in the plugin C-Max when in battery depleted engine mode.

I have experienced a range of fuel economy in gas mode.  The car is particularly sensitive to driving style, terrain, and climate, more so than other mainstream hybrids like the Prius.

Ford notes this to be the case because the car has 50 more horsepower so has the potential of faster acceleration which can cause steeper drops in economy.  They also claim a 5000-6000 mile break in period is required to get to maximal economy.

In my testing, driving freestyle and including about 75% highway driving, over 20 miles I will generally see fuel economy of about 34 mpg.  In the same drive, I found also I can get above 40 mpg if I am careful and use some mild hypermiling techniques.  This is in below 40 degree temperatures, with headlights on and 72 degree cabin heating.

Presently my car only has 200 miles on it.

I have found the maximal EV range from a full charged battery is 15 miles.  This includes driving carefully.  I have no doubt that in the warm spring climate the EV range will increase, as will the gas mode fuel economy.

Of interest, I have also noticed the gas engine goes on to condition the battery at 39 degrees or below, even if you set the car to EV now (see photo above).  The gas engine will run for several minutes.

All things considered I am  very satisfied will the vehicle's fuel economy considering its large crossover design and three seat rear bench.  It also has a wide range of driving capability and a very high degree of sensitivity to driving style, which can be fun to experiment with.  Drivers need to understand their role in fuel economy.
