I was under the impression that when using the normal brake pedal, that it still uses regen if possible. The meter over on the left of the cluster shows regen where the amount depends on how hard you press the brake pedal.
Try using the "electricity use" menu while driving. Under "drive train" it will accurately display regenerated power in kW and is a good reference for efficient driving.
I described the test you can do to prove that no hydraulic gets used except in extreme conditions. Apply the pedal slowly and try to use even braking force all the way into your stop. It takes a bit more prediction and paying attention to traffic sometimes. _H*
I use regen level one and use brake pedal to stop, applying even pressure. My range in summer was over 480 km and yesterday I charged to 100% and the range was 450, so I think that is good considering 85% of my driving is on highways at 100+ km, and temperatures are lower now.
I have an easy fairly flat 50km circuit in town, flowing light traffic off-peak, which I have done twice, more or less the same conditions, one at level 3 regen and one today at level zero. So for both the Kona returned 9.0kWh/100km (6.9ml/kWh), averaging 40kph (25 mph), stock tyre pressure. The last 10km (flat waterfront) was at a steady 8.8. An impressive vehicle, but I'll leave the regen 0 to you, I find 2-pedal driving so retro after getting used to L3...
I'm back I'm glad I just drive my car as normal regen 3 then when the battery gets low I plug it in. That way I don't have to calculate every KM I drive. I bet if some people here just got in there car started it and just drove normally(what ever that is for you) you would enjoy your Kona Better. Also by doing that you probably wouldn't notice more battery use then you did by diddling around. This is just my thought.. I say diddle away to your hearts content if you like to.
We "diddlers" post in these forums precisely because we enjoy discussing all the technical aspects of our cars. If that doesn't turn you on, then you know what to do...
To each their own as far as making the car slow down, but thanks for doing the comparison and I'm glad you got the [unchanged!] results that you did. I'd have to work at it to pull a 6.9 mi/kWh segment; nice going! We can almost do no wrong with these cars with a modicum of attention paid. _H*
