Toyota GR Yaris review – MPG and running costs

Short gearing, a big turbo and the tiny fuel tank will make trips to the bowsers a common game

Evo rating

A side effect of having so much performance and short gearing to access it is that despite its economy car cylinder count, each uses a quite astonishing amount of fuel. Official figures suggest as much as 34.3mpg is possible, but over the life of our long-termer we averaged a stunning 25.6mpg over six months of admittedly, erm, full use.

The performance to consumption ratio doesn’t feel out of whack, mind, because as mentioned above, the GR is insatiably quick across the ground.

What reinforces a feeling of thirst is the tiny fuel tank; concentrate hard and you can almost see the needle drop under acceleration. Other than fuel use, though, Toyota’s usual reliability factors ring true, with our six months coming with not a single unforeseen cost – it even held on to its rubber despite multiple track days over some 5000 miles.
