New Hyundai Ioniq vs Toyota Prius

Our verdict

Both cars are genuine alternatives to regular diesel hatchbacks. The Toyota Prius, particularly, makes sense if you do a lot of town driving, where it’s really frugal, while the Hyundai Ioniq is a closer match to a diesel’s economy on the motorway. By a narrow margin, though, the Ioniq triumphs.

It is disappointing that it’s pricier to run as a company car and to lease, but the differences are relatively small, so we feel this is outweighed by the fact it’s quicker, more fun to drive and better equipped.
