Who the BYD Sealion 6 suits
The Sealion 6 Essential suits a buyer who wants an SUV with a plug at a lower price, at $42,990 (RRP excl. on-roads). As a PHEV with a 60L fuel tank, it also suits someone who can't always charge at home or on the road. It has a braked towing figure of 1,500kg, so it's the one of the two with a braked towing number on record.
Who the Zeekr 7X suits
The Zeekr 7X RWD suits a buyer ready to go fully electric and spend more, at $57,900 (RRP excl. on-roads). It has 310kW, a 539L boot and a WLTP range of 480km. Max DC charging of 450kW makes it the pick for people who plan on long trips using fast chargers.

Practicality
Both cars are SUVs with 5 seats. The 7X is 4,787mm long and 1,930mm wide on a 2,900mm wheelbase, against 4,775mm, 1,890mm and 2,765mm for the Sealion 6. The BYD has the tighter turning circle at 11.0m versus 11.6m. For towing, the Sealion 6 is rated at 1,500kg braked and 750kg unbraked, while the 7X is rated at 750kg unbraked and we have no braked towing figure for it.
Cost to tow
The real fuel/energy cost once you hitch up. Pick a trailer and trip.
⚠ PHEV: the rated tow capacity is legal, but once the battery is depleted it tows on the petrol engine alone — expect noticeably lower speed on highway climbs and much higher fuel use (real-world tests hit ~30 L/100km near capacity on a flat battery). Keep some charge in reserve for hills.
Estimate only: consumption rises as range falls; real use varies with terrain, wind and load.
Will it fit in the boot?

BYD doesn't publish boot dimensions for this car, only 425 litres. Litres can prove something won't fit, but never that a rigid item will - so the best this car can score is "May fit".
