- More Accurate Engine Calibration: For the fifth generation system, Toyota experts have refined engine calibration. Better drivability, smoother performance, and more power output follow from this.
Two Engine Options
- 1.8-liter engine: This choice offers 140 horsepower (hp) of overall system output and lower CO2 emissions than the fourth generation system.
- 2.0-liter engine: With its 196 horsepower, the 2.0-liter engine provides a more potent driving experience.
Benefits over 4th Gen Hybrid System
Here’s how the 5th generation system surpasses its predecessor:
- Increased Power and Performance: Both engine options offer more horsepower, leading to quicker acceleration and a more responsive driving experience.
- Improved Fuel Efficiency: The 1.8-liter engine boasts lower CO2 emissions, indicating better fuel economy. The electric drive ratio improvements likely contribute to this as well.
- Enhanced Drivability: Smoother power delivery and better engine calibration lead to a more enjoyable driving experience.
- Compact Design: The smaller electric motors contribute to a potentially lighter overall weight for the vehicle, impacting handling and efficiency.
