One of things I don’t like about the MPG figure on phevs is its based on petrol only and assumes that electricity is free.
Ive got one of these on order so not been negative by the way.
We borrowed one again for a few days and we live in a hilly area and couldn’t get 20 miles out of the battery only and on one occasion at an higher speed only achieved 12 miles which is poor and more expensive to run in pure than petrol on that occasion
