The AutoCar reviewer states "The driving experience suggests that IONIQ Electric is positioned for normal driving, but without a sporty feel:".
I can't argue against this because I never tried to drive the car other than normally. If 'fun to drive' is what you are looking for then it seems there are better choices than the IONIQ Electric. It seems rather dull but perhaps the best review of the IONIQ Electric would be to state that it is 'well positioned for normal driving'.
I will argue against the AutoCar reviewers poor understanding of regen.
You can alter how much the car decelerates when you lift off by using what look like gearshift paddles behind the steering wheel. The Ioniq starts with fairly weak regenerative braking initially, but this can be ramped up to slow the car faster and increase the amount of energy that goes back into the battery pack.
Although this does improve range and allows you to avoid pressing the brake the majority of the time, the regenerative braking is much more sudden than in a Nissan Leaf, for instance. We soon turned it back down again to make smoother progress.
It is regen zero (coasting) that increases range on the freeway; regen three (max regen) is useful when driving slowly down a steep, windy mountain road. (regen 1 is the same as 'D', regen 2 is the same as 'B')
Kia copied the Nissan Leaf when developing the Soul EV. The system of having 'D' and "B' modes is a halfway house for drivers who are new to EVs coming from ICE cars. Am glad Hyundai dropped this concept for a more sensible EV based system.
