The 2009 Toyota Yaris features a range of new and revised engines that benefit fully from the technical advances delivered by Toyota Optimal Drive. The line-up comprises a new 1.33-litre Dual VVT-i petrol unit with a Stop & Start system and improved versions of the award-winning 1.0-litre VVT-i three-cylinder petrol unit and the 1.4-litre D-4D diesel. A new six-speed manual transmission also debuts in the Toyota Yaris. Matched to the 1.33 VVT-i and 1.4 D-4D engines, it is smaller, lighter and more efficient than the five-speed gearbox it replaces.
Applying Toyota Optimal Drive technologies gives the engine superior emissions and fuel consumption performance compared to the previous 1.3-litre unit, reducing CO2 output by 22g/km and improving combined cycle mpg from 47.1 to 55.4 (both figures for manual transmission with Stop & Start). The Toyota Yaris engine is also smaller and lighter, but produces greater torque.
Stop & Start Technology
A new Stop & Start system is featured as standard on the Toyota Yaris 1.33 Dual VVT-i engine with six-speed manual transmission. This automatically stops the engine when the gear shift is moved to neutral and the clutch pedal is released; the engine restarts as soon as the clutch is depressed again.
Immediate restarting is made possible by a permanently engaged gear mechanism and there is no hesitation in a rapid stop and start sequence - the engine does not have to stop fully before firing into life again. The system reduces fuel consumption and CO2 emissions, and operates smoothly and silently.
