As far as range is concerned I would personally sacrifice 40/50 miles of distance per charge in exchange for greater stability and safety. It’s easy for me to say though because I average just 80 miles a week with very occasional longer journeys, and I am usually the only person in the car so I only have to think about myself. Those of you who have much higher mileage to cover and passengers with their own needs will probably have different opinions.
As I’ve mentioned before, I also think the 20″ wheels look superb on the ‘6’, and complete the eye-catching look.
