The Yaris, Toyota’s best-selling car, has been substantially re-engineered for improved fuel consumption and lower emissions. The new 1.33-litre Dual VVT-i engine with automatic Stop & Start system gives best-in-class fuel economy with 55.4mpg.

No model in the new 2009 Toyota Yaris range emits more than 120g/km of carbon dioxide, thanks to the adoption of Toyota Optimal Drive across the entire range.

Toyota Optimal Drive, introduced at last year’s Paris motor show, covers a range of technologies that promote greater powertrain efficiency. Toyota’s engineers have improved combustion efficiency, reduced engine and transmission weight and reduced friction to produce engines that deliver more power and are fun to drive, yet at the same time are more efficient and economical.

The 2009 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 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.

Toyota’s 1.33-litre petrol engine is new to the Yaris range, having made its debut in Auris and new iQ at the end of last year. It features state-of-the-art Dual VVT-i (variable valve timing – intelligent), produces 100bhp (101 DIN hp) and has the highest compression ratio of any petrol engine on the market at 11.5:1. The in-line four-cylinder unit produces 132Nm of torque at 3,800rpm and returns 55.4mpg in combined cycle driving, with both six-speed manual and MultiMode transmissions.

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 engine is also smaller and lighter, but produces greater torque.

Advanced engineering was applied through the development of the new engine, with streamlining of the intake channel, and smoothing of surfaces and rounding off of all angles and edges inside the block to improve airflow and reduce turbulence.

A new Stop & Start system is featured as standard on the 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.

Within the B-segment the Yaris 1.33 Dual VVT-i is also the only model in its class to fall within band B for Vehicle Excise Duty, giving an annual road fund licence bill for 2008/9 of just £35.

Toyota’s three-cylinder VVT-i petrol engine has twice been a category winner in the sub-1.0-litre category of the International Engine of the Year Awards and enters 2009 with even better fuel consumption and emissions performance. Toyota engineers have worked on the unit to deliver the following improvements:

* A new cut-off system to save fuel during gear changes
* Improvements to the Electronic Fuel Injection (EFI) management
* Use of low viscosity oil for less engine resistance
* Adoption of an exhaust gas recirculation system and cylinder block water jacket spacer to increase efficiency

One of the lightest engines on the market today, it delivers class-leading specific power and torque, with 68bhp (69 DIN hp) at 6,000rpm and 93Nm at 3,600rpm.

TR versions of the 2009 Yaris ride on low rolling resistance tyres, further contributing to lower fuel consumption and CO2 figures. Together the measures achieve a reduction in CO2 of close to 10 per cent compared to the previous model.

The 1.4 D-4D diesel engine features latest-generation common rail technology and an intercooled turbocharger.

Official combined cycle fuel consumption is substantially improved, cut from 62.8 to 68.9mpg with manual transmission, 67.3 with the MultiMode (M/M) gearbox. Likewise emissions have been reduced, falling from 119 to a class-leading 109g/km (110g/km with M/M).

As part of the Toyota Optimal Drive technology applied to the new 2009 Yaris a six-speed transmission has been developed for the 1.33 Dual VVT-i and 1.4 D-4D 90 engines. This new unit delivers world-class efficiency and improved fuel economy, thanks to a wider ratio for sixth gear.

Styling changes for the 2009 Yaris are evolutionary, designed to strengthen the car’s dynamic and sophisticated qualities.

The Yaris grade structure has been revised with two new focus grades, TR and SR, plus the established T2 and T Spirit trim levels.

Yaris continues to be built at Toyota’s Valenciennes factory in France. Toyota Motor Manufacturing France (TMMF) has achieved a three-year plan target to recover and recycle 100 per cent of the waste products from industrial and housekeeping processes. Having achieved zero waste to landfill since the site opened in 2001, and a 50 per cent reduction in the amount of waste generated, the company has now gone even further by sending no waste for incineration.

Manufacturing a Yaris produces 9.5kg of waste, more than 4kg of which is directly recyclable (cardboard, metal, oil solvents, etc). The remaining 5.5kg are used as substitute fuel, for example in place of oil, in industrial processes.
