Was away on holiday last week so a couple of 80 mile journeys completed. Definitely quieter than the NX, more relaxed ride (possibly due to longer wheelbase) and certainly a Lexus where you simply waft along. Seat comfort similar to NX.
Definitely a bit thirstier (as expected). Hopefully temperatures will rise which should improve ev range.
660 miles on the clock and still got quarter of a tank. Once I refuel and calculate the electricity consumed I will report on overall mpg.
