What about tow ratings of passenger cars ? Though i have pulled 2 ton tractors
(loaded trailer 2500kg or 5500lbs) with my 2.5TDI, it is legally allowed to pull 1600kg or 3500lbs.
In the USA passenger cars arent allowed to pull that much ??
It's the subject of a whole 'nother thread. It is a long one on TBN if you can find it.
Manufacturers set the tow limits, and you have to dig for them for cars. After-mkt makers make
most hitches (Draw-tite, Curt, etc.) and they set limits, too. Hitches are made for most vehicles,
even if the car maker is mute on towing, or specifies no towing.
The car makers have arkane or arbitrary limits on the tow capability of cars, though there seems
to be an industry spec that applies limits on towing based on how fast you can go up a certain
grade.
Seems to me that virtually any car can tow a trailer if you can make or have made a hitch that
attaches properly to subframe members. Indeed I helped my bro get a hitch for his 2010 MX5 Miata.
US car makers seem to discourage towing with cars, steering buyers to pickups and vans. In the
old days, car towing was common here. Indeed, in the 60s, my dad towed a travel trailer that must have
weighed over 4T with a Ford wagon with large V8 engine and weight-distributing hitch.
