Toyota is conducting research and development for cutting-edge technologies in various fields to provide appealing products and services that meet the needs of customers around the world.
Toyota Hybrid Synergy Drive®
Toyota is carrying out efforts to contribute to the preservation of the global environment by helping to create social systems and developing technologies, in pursuit of a recycling-based society.
Hybrid Synergy Drive® (HSD) is the concept behind the new generation of hybrid vehicles from the Toyota brand, including the Toyota Prius, the world’s best-selling hybrid vehicle. HSD combines driving pleasure and performance with fuel economy, low emissions and silent driving. The word “synergy” extends to the higher synergy between the petrol engine and electric motor to power the vehicle. The electric motor is now more powerful, allowing a higher ratio of electrical/petrol usage. The results are more performance with greatly improved efficiency.The benefits of Hybrid Synergy Drive® in the Prius
- Excellent driving performance: acceleration similar to a mainstream D-segment diesel engine.
- Low fuel consumption: 4.3 litres/100 km – equivalent to a B-segment diesel car.
- Lower emissions: CO2 emissions of 104 g/km in the combined cycle, down from 120 g/km for the previous generation.
- Silent driving: HSD can run on the electric motor only, offering a completely silent driving experience. B-segment cars are compact cars like the Toyota Yaris. D-segment cars are larger, more powerful cars such as the Toyota Avensis.
The Toyota Prius has already captured 90% of the world market for hybrid technology, having been on the market since 1997. The Prius was voted the 2005 European Car of the Year – a strong endorsement for environmentally beneficial hybrid technology.
VVT-IComputer control for a more efficient and powerful engine.
An intelligent computer optimises the engine’s oxygen intake by varying the timing of the intake valves. The result is a more responsive car with
- Engine flexibility that reacts like a larger capacity engine
- More power at high engine speeds
- More torque in the lower speed ranges
- A more efficient engine with enhanced fuel economy and lower emissions.
The ZR engines are known as the “Fuel efficient engines” for better performance and less impact on the environment.
Previously we used to have the E engines(1980s), thenA-FE engines (1990s) and lately the NZ-E engines (2000s). Variable Valve Timing is a technology which lifts and close engine valves as and when required. ZR engines are dual VVT-I with both intake and exhaust valves are controlled electronically.
In this way it ensures optimal performance based on engine operational condition, giving high fuel efficiency and driving performance. As a rule, controlling the exhaust gases and intake air allows better Torque, which translates to the engine power going to the wheels. Two pictures below shows the difference in the mechanism.
D4-DExcellent fuel economy from a regular diesel engine.
The secret of the Toyota D-4D’s outstanding performance is an electronic control unit that accurately balances fuel injection pressure, timing and volume according to the demands being made on the engine. As a result, the engine always
- Works at maximum efficiency
- Delivers the optimum in power and torque
- Provides excellent fuel economy
Derived from world leading safety technologies, all Toyota vehicles provide dependable safety.
Automotive safety is one of the factors that must be given top priority in car making. To this end, Toyota is working on R&D activities to produce vehicles that will perform at the highest level of safety and ensure comfortable driving under various conditions.
As Toyota vehicles are delivered to customers around the world, safety technologies must be developed from a global perspective.
Based not only on the vehicle safety standards around the globe but setting our own exceedingly high targets, Toyota is working hard to develop world leading safety technologies.
Toyota's concept of a safe car is one that must achieve both high level passive and active safety. Passive safety is the concept of helping to protect occupants in the event of a collision while active safety is the concept of helping to prevent accidents from occurring.
