2018 Chevy Sonic Front Wheel Drive...

Not sure the exact nature of the question, but yes you can tow a Chevy Sonic on a dolly, some models can be towed 4 down. If you’re concerned about weights, the combo of a dolly and sonic (unless loaded with rocks) should be well below your max tow numbers.

I had a 2013 Sonic w/automatic and towed it 4 down. Good car. Newer ones have more electronics and such so consult your manual on the exact procedures required to tow it.

If you use a tow dolly, I would suggest a couple things.
Get one with brakes. Surge brakes saves installation of wiring and brake controller in MH.
If possible, get a small hitch for Sonic to enable you to move dolly around.

Nice to hear from you Bagman. It has been a long time since I read anything from you. chevman retired from rving
