Having driven a Chevy Bolt EV in Canada for 2 weeks recently, with a very similar spec (60kWh and 150kw motor - also from LG Chem - and 400km real world range) , the Kona will be an awesome car.
This is Auckland to Wellington with one 45 minute stop along the way for a meal and charging.
My longest, single leg in Canada was Port Severne to Azilda (west of Sudbury) and was just under 300km. I had only charged to 85% at Port Severne......and still have 21% left at Azilda. So 64% got me 300km of actual highway driving.....
I'm still hanging out for the Tesla Model 3 so I can use the 120kw superchargers......but the Kona is available right NOW.
I may get a Kona and switch to a Model 3 next year........having driven a 400-450km EV already and LOVED it.
