Our next towed will probably be an electric car. We are considering a Nissan Leaf or a Tesla Model 3 (if it ever comes out and is actually cheaper than the Model S). Has anyone on the forum ever towed...
As noted above, the Ford C-Max Energi is towable 4 wheels down as is the Ford Fusion Energi. These are both plug-in hybrids with larger lithium ion batteries than the standard C-Max and Fusion hybrids.
