It's worse than that.
Yes, SOME Malibu models are Towable
BUT, Not All. The MoHo Magazine Guide says
Only 1.5 Liter Models Without Active Shutters can be Towed
See Page 356 Here.
Chevy has an odd way of expressing this, but several models are excluded from towing, a model called Premier for one. Not clear if 1.5 w/out shutters also means non-turbo, but I'd guess it might.
