I will add my tuppence worth here too as a month ago I part-exed my lovely 5 for a second hand Kona too.
I agree with
@Tweed98 comments but will add some of my own thoughts and for reference I swapped the PFL LR Exclusive (top of the range) for a Kona Ultimate facelift (also top of the range).
On the downside, the ride on bumpy A/B roads is not quite as good, a bit more bouncy/jittery, but OK unless you are boy racer.
Also the speedo overreads like 'normal' cars. I have become so used to the speedo being accurate on the 5, and ZS before, that I don't like it overreading. By 2mph. I checked it with OBD attached using Car Scanner while driving showing the 'real' speed which is accurate but the displayed speed is adjusted up by 2mph. Grrr.
It has 3 trip meters but only one is useable/resettable, not good. The first shows current drive, much like the 5 and resets each time the car is turned off. The second, although I can reset this one, it resets itself every time the car is charged anyway. The third , the accumulative is the only one fully under my control.
There is a lot less space than in the 5 or the ZS, this is a small crossover. This isn't a problem for us, there is only the 2 of us and only rarely carry passengers any distance.
There are many more similarities however between the cars in terms of features and gadgets than there are differences really. Probably applies to all EVs it's just the way they are implemented/controlled.
KERS/regen, I like the flappy paddles and played with them a lot initially until I turned on smart regen, whereby the car chooses how much depending on 'things' such as speed, cars in front, incline etc. It seems to work well so rarely touch them now, but I can still use them to temporarily override if I want.
As above the LKA I hardly notice if I forget to turn it off, which is simply by pressing a button on the steering wheel, lovely and easy.
The MG pilot equivalent works very very well, smooth lane keeping and distance management, although as in the 5 I like to steer myself so generally just use ACC.
One of the reasons for me changing was the getting in and out of the car. Now the car itself might not be that much higher than the 5 but the seating position is more sit up and beg style than the legs straight out in front style. I used the seat in the lowest position in both the 5 and the Kona.
Mine also has a sunroof, not a panaromic but the old fashioned tilt or retract type. Nice open so long as the sun isn't shining.
Economy: Wow this thing covers some distance. The useable battery is 64kWh and the efficiency is incredible. Pootling around town I can get anything up to 7 or 8 m/kWh not just over a mile or two but 10 miles. Not all the time of course sometimes it does go as low as top 3 point something.
On the motorway I have no hesitation in cruising at 70 (68 - see above) whereas in the 5 I tended to stick to 63/65.
The other weekend we did a day trip to Southport and back for a food festival, which was very good, and M62/M61 was a 110 mile part of a total journey of 160 miles. Now I've always regarded the M62 over the top of the Pennines a bit of a range killer. The journey was done with ACC set at 70 for the whole motorway part.
The final figures for the day was 158 miles travelled, 4.9miles/kWh and 48% SOC left after starting at 100%. This is a true 300 mile range car.
The other outstanding feature was the GOM which showed a range of 317 at the start. Google maps showed journey of 79 miles to our destination. On arrival the GOM showed range remaining of 239 - bang on. I have no idea how it did that. It's not always that pinpoint accurate but is very much more so than anything I've had before.
I like the way things just work. I plug in my phone and Android Auto just works, I had to buy an AA Wireless to guarantee connection in the 5.
The app. Never had one before so can't really compare, but it works and I can do things with it. I didn't need to contact anyone to connect with it, I just downloaded the app. When picking up the car, the dealer showed me the reset option in the infotainment to clear previous user and I registered my app in there and the car in my app. Job done before we drove off
There are other differences, but that's all they are. I wouldn't say one car is better than the other, just different.
P.S. Regards the trip meters, the accumulated has never been reset since the car was new and it shows the lifetime m/kWh as 4.8. As a November 2022 reg, that's 2 winters and 1 summer, I don't think that's too bad.
