Towing capacities are obviously (seeing these numbers) very dependant upon government regulations, based on... different criteria depending on where you live.
There are a few things I see here though :
- About the Tow group vs non Tow group ratings : I recall that Aussie KLs all have a tow prep package, so perhaps some European KLs have them as well, meaning they already have the coolers and anti-sway programming ready to go even if the windows sticker doesn't say "Trailer Tow Group". Yeah I know it's a stretch, but who knows...
- I4 vs V6 having the same capacity : that's a strange one for sure, strange from a North American perspective anyway. But when you think about it, the frame, brakes, tires and tranny are the same, it's just less engine power, really. So perhaps they aknowledge something our regulators refuse to see : 100 less ponies doesn't mean less towing capacity for vehicules otherwise identical (nearly identical).
Off on a tangent here : I remember the look of disbelief on my favorite FCA salesguy's face when I told him a few years back that the Journey had gone from 3,500lbs towing capacity down to 2,500lbs in 2011 (IIRC), with a more powerful engine than the previous model years (3.6 Pentastar) mated to a 6-speed. Even for the AWD trims, 2,500lbs is the upper limit. He didn't believe me at first, so off he went to his computer... and then he saw it... And then he admitted telling one or two customers that 3,500lbs was still the number. Oopsy.
Why ? Even a FWD Cherokee with a 3.2 can tow 4,500lbs and it isn't really *bigger* than a Journey. Good question. I still don't have the answer (haven't looked that hard though). Maybe because of brake problems on the Journeys..? Ok I'm done now..
