The C-Max is an appealing all-around package, combining the fuel efficiency of its standard hybrid powertrain with the practicality of a five-door hatchback design. Based on the Ford Focus, the C-Max packs an impressive amount of room and utility into a small footprint. Its tall stance and low entry height make for easy access, and the cabin is airy and spacious.
With the C-Max Hybrid, Ford takes direct aim at the Toyota Prius and its extended family. At 37 mpg overall, the regular C-Max isn't as fuel efficient as the Prius models, nor is it as roomy. But it's much quieter inside, making the C-Max feel solid and substantial. And it's more fun to drive, with precise steering, responsive handling, and a luxurious ride.
Transitions from gas to electric power are smooth and unobtrusive, and the engine isn't really loud unless you're pushing it hard. Even then, active noise cancellation keeps it from being offensive. We found that the C-Max can drive up to about 35 mph before the gas engine starts. When you need full power, the engine will come on at full throttle or highway speeds above about 70 mph.
Stopping distances were good. But we found that the regenerative braking, which helps recharge the battery, can make the brakes feel touchy.
The C-Max's tall stance and low entry height make it easy to get in or out, and the cabin feels airy and spacious. Large windows give a great view of the road, though the driving position is a bit narrow. The rear seat is a bit flat and low but roomy enough. The optional Sync 3 infotainment touch screen is easy to use, and a backup camera is standard.
Similar to the Prius Plug-in model, the Energi version of the C-Max is a plug-in hybrid that lets you spend more time driving on energy-saving, cost-cutting electricity than the regular C-Max. With its larger battery, the Energi lets you go about 18 miles on electric power before the conventional hybrid mode kicks in. However, the battery significantly cuts into the Energi's cargo space.
We got the equivalent of 94 mpg overall with the Energi running solely on electricity. Once it reverts to normal hybrid mode, we measured the same 37 mpg as in the regular C-Max. Two handy buttons on the center console let you choose whether to run the car on electric power only or in the regular gas/electric hybrid mode. "EV Now" activates electric mode (as long as the battery is sufficiently charged); "EV Later" lets you save the electric-only miles for later use. That could be a big benefit if you expect to, say, drive in congested city or rush-hour traffic, when EV mode will be most efficient.
The Energi takes 6 hours to charge on a normal 120-volt household outlet, or 2 1/4 hours on a 240-volt electric-car charger, which is also a little more efficient. Either way, if your commute fits within the Energi's 18-mile electric range, you can drive for about 70 cents per day (based on the 11-cents-per-kWh national average) and skip the gas pump altogether.
