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-segment¹ diesel engine.
  
• Low fuel consumption: 4.3 litres/100 km – equivalent to a B-segment¹ diesel car.
  
• Lower emissions: CO2 emissions of 104 g/km in the combined cycle², 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.  

¹ B-segment cars are compact cars like the Toyota Yaris. D-segment cars are larger, more powerful cars such as the Toyota Avensis.
² City and highway driving.

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.
