Toyota Optimal Drive is a new concept in powertrain engineering and design that is being applied to all new Toyota models. Toyota Optimal Drive means no compromise on performance, emissions or specification. On the Toyota Avensis, it brings new engine technologies and advanced transmissions, with low friction components, lightweight compact design and enhanced combustion efficiency.
New 1.8 and 2.0-litre Valvematic Engines More Power for Less Fuel
Valvematic is an innovation based on Toyota's proven dual Variable Valve timing - intelligent (dual VVT-i) technology. In addition to the variable timing of the inlet and outlet valves, Valvematic adds a lift control system that continuously varies the lift of the inlet valves to better control the volume and speed of the intake airflow. This provides a breakthrough in combustion efficiency that ultimately delivers more power for less fuel.
Across the range the new 1.8 and 2.0-litre Valvematic petrol engines achieve a reduction in CO2 emissions and fuel consumption of between 10 and 26 per cent, while at the same time increasing power by between three and 20 per cent, compared to the VVT-i engines used by the previous generation Avensis.
Revised D-4D and D-CAT Diesel Engines Up to 10% Lower Emissions
The new Toyota Avensis offers customers one of the most comprehensive ranges of diesel engines in the D-segment, all of them benefiting from Toyota Optimal Drive technology. Entry point is the 2.0-litre D-4D 130, followed by the 2.2-litre D-4D and D-CAT 150 as mid-power options, and the 2.2 D-CAT 180 as the higher power unit (the D-CAT 150 engine with automatic transmission will join the range in spring 2009).
The challenge was to develop these engines to give excellent performance and low CO2 emissions and fuel consumption, while at the same time achieving a substantial reduction in the level of particulate matter (PM) and nitrogen oxides (NOx) emissions. Together the new diesel engine technology features deliver a reduction in CO2 and fuel consumption levels between one and 10 per cent compared to the previous generation Avensis; the 2.2-litre D-4D 150 and 2.2-litre 150/180 D-CAT engines all meet Euro V emissions standards.Published 4 December 2008
