Heated seats won’t make a blind bit of difference to the range, neither will heated steering wheels but they both make cold weather driving so much more enjoyable.
Using the heater may reduce the range, accelerating away from a standstill quickly will, driving too fast certainly will, driving in heavy rain does cause it takes a lot of energy to push through those puddles.
Carrying lots of passengers or heavy items in the boot has very little effect on range.
Don’t pay too much attention to having only “134 bhp”, electric cars are rapid off the line so drive one and see.
Go onto YouTube and look for “Fully Charged” for an honest assessment of both cars but if I had one I’d expect to get 150 miles minimum range.
