We are towing a Ford C-Max Energi. Bought to tow but now our daily driver while the bigger gas guzzlers stay in the driveway! Tows great with no restrictions except you do need a charge line.
Roomy interior with lots of headroom. Also has a great Federal tax credit! With the electric miles for daily errands and plugging in at campgrounds our overall average went over 140 mpg last summer!! :) We are down to an overall average of 120 now because the electric battery has less range in the colder months.
Our favorite car ever!!!! :)
