No replacement for displacement....

Yes there is - it's called engineering.
My tow vehicles have always been 2L turbocharged diesels (Saab & BMW), and for the last 12 years with 6 or 8 gear automatic transmissions.
Towing trailers from 1100 kg to 1500 kg in alpine terrain over thousands of kilometers - never any worries.
Never checked the oil or water. Never had the auto mindlessly shifting around. Just drive and listen to the music.
