Improvement of a Highly Efficient Hybrid Vehicle and Integrating Super Low Emissions 2000-01-2930

A new hybrid system has been developed which features a highly efficient, clean gasoline engine, and a high performance exhaust catalyst system. The new system meets the strictest low emission standards in the world, while realizing a major reduction in CO2 emissions.
The Toyota Hybrid System (THS) has improved engine performance, transaxle transmission efficiency, and various vehicle improvements for improving fuel consumption. It also employs a high performance catalyst, a rapid catalyst warm-up strategy, Toyota HC Adsorber and Catalyst System (Toyota-HCAC-System) and a Vapor Reducing Fuel Tank System. These combined technologies allow for the achievement of U.S. California SULEV, European Step 4 and Japanese J-ULEV emission requirements. It has also lowered the CO2 level to less than 120g/km in EC European mode.
