A low-powered 68bhp, three-cylinder 1.0 VVTi petrol props up the range in smooth and sonorous fashion, but the 98bhp 1.33 VVTi installed in our test car, has been replaced with a new 1.5-litre naturally aspirated engine producing 110bhp and 100lb ft of torque , while a hybrid version with 99bhp completes the range.
Kicking off proceedings is the 1.0-litre three-pot. The pleasantly thrummy unit serves up 68bhp - and a torque figure to match - but its leisurely 15.3sec 0-62 sprint means it is left wanting when leaving the safety of slow urban traffic.
Downsized petrol engines are a natural accomplice to the supermini breed, and it’s no surprise that Toyota’s familiar 1.33-litre engine slots into the new Yaris neatly enough. The compact four-pot forgoes the current vogue for forced induction with its long-established Dual VVT-i variable valve timing system, now with minor internal revisions to boost fuel economy.
This engine can sometimes feel breathless and flimsy at very low revs – indicative of efforts made to keep the Yaris as parsimonious as possible around town – but with a maximum 92lb ft of torque available at 4000rpm and the full 98bhp at 6000rpm, it does eventually pull with some vigour, making conservative overtaking a realistic prospect.
