Prius Fuel Efficiency
Outstanding energy efficient hybrid vehicle
At 4.3ℓ/100km Combined (5ℓ/100km Urban, 4.2ℓ/100km Extra urban)*, fuel consumption of Prius is among the best in the world. Prius has one of the best aerodynamics for production passenger cars in the world and incorporates many weight saving features, which all combine to realize this outstanding fuel efficiency.
1. Superb aerodynamics, Cd=0.26
- Unique roof panel form for streamlining effect and reduced frontal projected area
- 3D curvatures of the side windows for lower drag
- Built-in rear spoiler to streamline airflow aft the rear-end
- Flat bottom floor design for smoother under-body airflow
- Air spats (front and rear) to reduce drag from air flowing around the tyres
2. Weight-saving design, approximately 140 kg lighter in total vehicle weight than if conventionally designed.
- Redesigned light-weight parts, right down to individual bolts.
- Extensive use of aluminum to replace steel.
- Extensive use of high tensile steel sheets
For USA: 65.7mpg Combined (56.5 mpg Urban, 67.3 mpg Extra Urban).
* The figure is for cars weighing less than 1,260 kg in total vehicle weight. In addition, the fuel consumption figure is for driving under specific testing conditions. Actual driving conditions (weather, road, vehicle, driving, maintenance, etc) may differ, resulting in variation in fuel consumption.
