Hi everyone. I have a BMW I3 Jan 2018 model (94ah Rex) and I just received my company car tax statment for 2020. It has me in the 8% tax BIK bracket which covers CO2 1-50g and electric range 40-69 miles. Whereas I am sure the range is a lot more than 70 as I always get between 100 (winter) and 150 (summer) on pure electric. My question is, does anyone know where the govt gets the electric range figures from as there are so many different measures that I am not sure which they go with.
