I would absolutely complain (if you haven't already) about being given a PHEV as a hire car with a flat battery!. Very poor show, if they aren't going to supply PHEV's charged, they should stick to HEV's or MHEV's.
Yes, a PHEV will use brake regen to put power back in the battery in the same way a HEV does, but because its battery is so big (relative to a HEV), you'd never get more than a very small percentage of charge back in. The battery on a HEV is much smaller and designed to discharge its power and recuperate it quickly.
If HJ says the Kuga is nimble, I suspect that may be relative to other PHEV SUV's (as traditionally Fords do tend to handle pretty well). But I doubt I'd class the (circa 1850kg) Kuga PHEV as nimble!. I believe they mustered 225bhp originally or 243bhp now (presumably a facelift), so should be reasonably swift in a straight line with power in the battery (but that has nowt to do with nimbleness). Not sure what the power is using only the ICE, but I'd guess maybe 170(ish)bhp, which isn't that much to be lugging around all that weight.
That car's nigh on 50% heavier than my (albeit 19yo) Mazda3 saloon, a car with a similar overall footprint and interior/boot space.
I suppose that's part of the problem with PHEVs - they aren't really a full EV or ICE car, just about 66% of both, but lugging around a hefty sized engine or EV motor & battery combo that for most of the time, one of them does nothing but take up space and weigh a lot.
That plus the car's default chassis / sub-frame and especially suspension is really designed for a lighter ICE-only or at best an MHEV car's weight, and presumably has needed beefing up to cope with the extra weight of the EV traction motor and battery pack.
To me, they are rather too much of a compromise vehicle, even in 'range extender' form where the fuel tank and ICE engine are much reduced to save weight and space.
That so many of such cars seemingly require (or at least only take) wide, low profile large diameter tyres which require a month's salary to replace (and are likely to need it more often because of the higher chance of damage) as well as suspension parts that take a 'hell of a beating' as a result with that extra car weight and lumbering handling, never mind the firm ride quality this doesn't enamour me to ever buying one.
As much as I don't think EVs are (yet) our saviour, at least they are just one tech and in theory simpler to look after, if designed and implemented properly.
Note that my dad's newish (2020) MHEV Fiesta MHEV weighs just 60kg shy of my bigger and older Mazda3 saloon. Newer cars have seriously put on weight.
