On September 24, Toyota Motor released the “Development of Environmental Protection Technology and Future Plans”, announcing that it will commit itself to the development of emission reduction and consumption reduction technologies, extensive use of electric energy, hydrogen fuel and Other new energy, and will release 21 hybrids by the end of 2015. car.

In addition, Toyota said that due to the misjudgment of the market demand for automotive battery technology, it will abandon plans to sell eQ compact electric vehicles on a large scale, and the focus of new energy vehicle business will increasingly shift to hybrid vehicles.

Energy Saving Technology

1、Gasoline engine

Toyota will develop an enhanced gasoline engine for hybrid vehicles based on a 2.5-liter AR engine using Atkinson cycle and D-4S4 direct injection system. The engine will achieve the highest global thermal efficiency in its class, reaching 38.5%, taking into account high power output and high fuel economy. The hybrid car equipped with this engine will be released from 2013.

From 2014, Toyota plans to release a new car equipped with a 2.0-liter turbocharged AR engine, which is also based on a 2.5-liter AR engine. The new engine reduces the displacement and improves fuel efficiency, while the turbocharger system improves power output.

2, diesel engine

Toyota took a number of improvements for the 1.4-liter ND diesel engine, such as increasing the pressure of the fuel injection system and adopting a compact high-efficiency turbocharger to achieve high power output and high fuel economy. The engine is also fitted with newly developed exhaust gas purification technology to meet the world's most stringent Euro 6 emission standards. The passenger car equipped with this engine will be released from 2015.

The 3.0-liter KD diesel engine is used in commercial vehicles. The engine is equipped with the world's first fuel injection system that maintains high-precision injection under high-pressure conditions, reducing emissions and improving fuel efficiency. Toyota first used the engine for Hilux pickups, and it was listed on the Brazilian market in April 2012.

3, transmission system

Toyota's newly developed Super CVT-i continuously reduces the size and weight, has high fuel economy and high ride comfort, and improves engine control performance. The transmission system was first equipped with the Corolla model of the Japanese market in June 2012 and is expected to be used in more models, especially compact cars.

Toyota's new front-wheel drive eight-speed automatic transmission weighs about the same as an ordinary six-speed automatic transmission, providing smooth shifting and responsive response, accelerating high-capacity, and providing excellent fuel economy. The transmission was equipped for the first time with the Lexus RX 350 F Sport SUV, which was launched in North America in August 2012.

4, hybrid vehicles

Toyota expects that the global sales of hybrid vehicles will exceed 1 million in 2012, and plans to introduce 21 new hybrid vehicles by the end of 2015, of which 14 models are new designs. The company expects to maintain the momentum of sales of hybrid cars this year. The sales volume of hybrid vehicles will reach at least 1 million vehicles/year from 2013 to 2015.

According to remarks made by Reuters, Toyota’s Vice Chairman Takeshi Uchiyamada, Toyota launched the eQ pure electric version of the iQ mini-vehicle in 2010. It had been expected that the car will have annual sales of several thousand units; It was found that the vehicle has a shorter mileage, a longer charging time, and a relatively high cost, and cannot meet market demand. In the future, Toyota will only sell about 100 eQs in the United States and Japan through leasing.

The focus of Toyota's future new energy vehicles will increasingly shift to hybrid vehicles, and will focus more on research and development of hybrid technologies. The electric version RAV4 jointly developed by Toyota and Tesla Motors will become the only large-scale pure electric vehicle in the product lineup, which will be available for sale in the United States this month. Toyota expects its electric SUV sales to reach 2,600 units in the next three years.
