Toyota Yaris review - MPG, CO2 and running costs

Toyota has designed the Yaris with low running costs firmly in mind.

MPG, CO2 and running costs Rating

4.2 out of 5

  • Great economy
  • Good looks
  • Entry-level models well-equipped
  • Not as spacious as rivals
  • Noisy CVT transmission
  • Firm suspension

A supermini with a starting price of around £20,000 doesn’t sound like particularly great value, although the Yaris entry price is pretty much on-par with the Renault Clio E-TECH and Honda Jazz hybrid that use similar hybrid technology.

You will, however, save money at the petrol pump, as Toyota claims average economy on the combined cycle of between 57.6mpg and 68.8mpg. During our own test over a mixed route we saw an average of 65mpg, with the high economy figures unusually maintained though town centre driving. 

CO2 emissions range from 92g/km to 98g/km, depending on which trim level you choose. The Honda Jazz isn’t quite as green, with CO2 emissions starting from 102g/km, while Renault’s Clio E-TECH supermini can’t quite match the Yaris either, with emissions of 98-99g/km. 

Company car users will incur a 21% BiK (Benefit-in-Kind) tax rate, which means a cost of £829 a year for 20% taxpayers.

Insurance groups

No matter which trim level you opt for, the Yaris shouldn’t incur expensive insurance premiums. The entry-level Icon sits in group 13, while all other versions are in group 14. In comparison, the 107bhp Honda Jazz starts from group 19.


Residual values for the previous Yaris, calculated over the standard three-years and 36,000 miles of ownership, softened over its model lifecycle to under 40%. Its Honda Jazz rival holds onto around 44% over the same period and, although it’s too early to establish definitive figures, we’d expect the fourth-generation Yaris to perform equally well.
