4th generation hybrid technology optimised for weight, package and efficiency
Includes new 1.5 Dynamic Force petrol engine with 40% thermal efficiency
Toyota’s recognised leadership in self-charging hybrid technology is built on more than 20 years’ experience. With billions of kilometres of driving experience around the world, Toyota hybrids have also proved their outstanding quality, durability and reliability. It is estimated that Toyota hybrid vehicles collectively drive over 500 million kilometres around the world every day.
Since the introduction of the first Prius back in 1997, Toyota Motor Corporation has sold more than 14 million hybrid vehicles worldwide – including 2.5 million in Europe – constantly improving the technology and introducing new models across a wide range of market segments. The Yaris Hybrid, the world’s first full hybrid B-segment model, was introduced in 2012, since when more than 500,000 have been sold in Europe, establishing it as a key product in creating wider public awareness and appreciation of the benefits of Toyota’s hybrid technology.
The 4th generation Hybrid system has been tested in different cities around Europe such as Rome, Paris, and Darmstadt. Results show that when it is used in an urban area, almost 80% of the time is been driving in Zero Emission Vehicle.
Those outstanding results are made possible thanks to the architecture of Toyota Hybrid System, basically providing all the elements of an electric car with high power motors and high voltage components and at the same time very efficient engine following the Atkinson cycle.
Toyota’s new, fourth generation hybrid technology makes its debut in the principal powertrain for the new Yaris. This 1.5 Hybrid Dynamic Force system is directly derived from the larger, 2.0 and 2.5-litre systems that were introduced in the new Corolla, RAV4 and Camry models and has been developed with the same level of scrutiny on component size and weight in the quest for ever-better fuel and emissions efficiency.
The hybrid system features the new 1.5 Dynamic Force three-cylinder Atkinson cycle petrol engine with variable valve-timing. As with its four-cylinder 2.0 and 2.5 counterparts, it benefits from detailed measures to reduce internal friction and mechanical losses and optimise combustion performance. In fact, the engine has the world’s fastest combustion speed, supporting high torque at low engine speeds and fuel efficiency. It is also fitted with a balance module, which helps reduce engine noise and vibration.
As a result, it achieves a 40% thermal efficiency, higher than typical diesel engines, helping secure a more than 20% improvement in Yaris’ fuel economy and CO2 emissions. At the same time, system output has been increased by 15% and power delivery refined to give a confident and natural feel.
The hybrid transaxle has been fully redesigned, adopting a new dual axis structure that makes it more compact (9%) The result is a low-loss gear train with smaller overall dimensions that improves performance and easily packages within the new Yaris’ GA-B platform.
The system also adopts a new lithium-ion hybrid battery with an increase in output that enables quicker vehicle acceleration. As well as being more powerful, the new battery is 27% lighter than the nickel-metal hydride battery it replaces.
The new Yaris will also be available with 1.5 and 1.0-litre three-cylinder petrol engines in selected markets. More details of these powertrains will be released at a later date.
