Fourth-generation Yaris has a frugal hybrid system that’s punchy enough even out of town while the interior is solidly constructed. It’s decent to drive, but rear seat space is average and its boot is a bit on the small side. It’s also pricier than rivals, but it’s worth bearing in mind that there’s no cheap, simple engine in the range and equipment levels are pretty generous. However, the Fiesta is more fun to drive and the Polo still the consummate all-rounder.
