While I am going through the same thing, I am thinking new Malibu vs Fusion which among the 2017 is limited - Base Malibu with the 1.5 engine only, and Fusion Hybrid (or Hybrid Energi) only for 4 down. The good news is that the 2015 Malibu owner's manual is online at Chevrolet.com (links at bottom of their web page in the owners section) and there was no engine/transmission restriction for 4 down or dolly tow the front wheels of the 2015. Just instructions on fuse pulls, typical of GM toads, and limit to 65mph.
