Toyota Prius Hybrid Engine Wins Green “International Engine of they Year” 2010 Award

Since its launch, the Prius has been a regular feature in the International Engine of the Year Awards. It is the fourth victory in five years for Toyota’s acclaimed Hybrid Synergy Drive system in the prestigious International Engine of the Year awards. Thanks to the improvements to the 1.8-lit drive-train, Toyota’s hybrid technology has finished 2010 with another victory.

A panel of 72 motoring journalists from 35 countries, tested and judged the engines for the 2010 awards, which were presented at Engine Expo 2010 in Stuttgart, Germany.

The latest four-cylinder engine features a larger and more powerful 1.8-litre Atkinsoncycle and produces 98hp at 5,200rpm in the new, award-winning Prius. Together with its electric motor, the hybrid system generates a combined 134 net horsepower, an improvement of 24bhp over the previous generation.

Not only the new, larger engine improves performance, it also helps improve highway mileage. The 2010 Prius can accelerate from zero to 60 mph in 9.8 seconds. By producing greater torque, the new engine can run at lower average rpm on the highway, thereby using less fuel.

In the Prius, Toyota has extended its record of continuous improvement in fuel economy, with the model’s fuel efficiency having gone from 6.89 l/100km (41mpg) in the first generation, to 6.1 l/100km (46mpg) in the second-generation, to now an EPA combined 5.65 l/100km (50mpg) in the latest incarnation.

Use of an electric water pump and a new exhaust gas recirculation system also contributes to the engine’s efficiency. The 1.8-litre engine is the first Toyota powerplant that requires no accessory drive belts, helping enhance powertrain efficiency and also potentially reducing maintenance costs.
