Summary
Reducing CO2 and fuel consumption is one of the major challenges for car makers nowadays. In 1997, Toyota introduced the world premiere Toyota Hybrid System (THS) as one of the most effective solutions to improve powertrain efficiency. The THS technology has been continuously improved to increase its efficiency while being expanded worldwide as a global technology. Recently, Toyota has renewed its 4-cylinder engine series for Hybrid Systems to increase thermal efficiency and to reduce CO2 emissions. In 2009, the 1.8L engine was launched as first engine of this new series, followed by the 1.5L and 2.5L engines launched in 2011. This new engine line-up is now integrated in a wide range of B, C and D-segment vehicles.
