Also it’s no surprise that company car drivers benefitting from BiK and paid mileage, will rarely charge their car after the novelty has worn off. So it’s no surprise they’ll be less efficient.
I average 120mpg each way on my 22 mile commute in the 330e when I charge at work (120mpg/60mpg when I can’t), so it shows that when purchased for the right reasons/journeys, there’s nothing wrong with them. 780 miles from one tank fill? Yes please.
Though I certainly wouldn’t have one as the main family car doing long distances, the Nissan Xtrail does that job. PHEVs are notoriously inefficient on long motorway journeys (though in my experience it drops to around 40mpg).
