To a degree yes, and to answer the other post, a lot of lowly medium size 2wd SUVs will have a higher towing capacity than estate cars which often struggle to top 1800kg.
An Audi A6 all-road is 2500kg and they cost a fortune compared to something like a Skoda Kodiaq capable of towing the equivalent . You could have a Audi Q7 on lease for a similar price to the A6 and tow even more, generally above 3000kg
This doesn't make them better at towing. Just means they can tow more weight as towing is down to the weight of the vehicle.
An estate towing a 1500KG caravan is going to be better than a SUV towing the same weight as it will have a better power to weight ratio and a smaller mass to slow down.
