Blank cells below mean we don't have that figure, not that the car scores badly on it. We leave them empty rather than estimate, so any row where one car is blank isn't a like-for-like comparison yet.
Plug-in hybrid fuel economy is shown as a hybrid (battery depleted) so it compares fairly with the other car. A PHEV's official "combined" figure assumes you start every trip fully charged, so real-world economy depends on how often you plug in. Electric range shows how far it goes before the petrol engine is needed.
