For the third year in succession, the 1.5-liter gasoline engine of the Prius Hybrid Synergy Drive powertrain has won both the International Engine of the Year Award in the 1.4– 1.8-liter category and the “Best Fuel Economy” category. The awards were made at the Engine Expo in Stuttgart, Germany.
The 1.5-liter, four-cylinder, Atkinson Cycle gasoline engine with Variable Valve Timing with intelligence (VVT-i), produces 76 hp (57 kW) and 111 Nm of torque on its own. With the 50 kW electric motor, the Prius drivetrain produces a combined 110 hp (82 kW).
Since 1997, Toyota has sold 613,300 hybrid vehicles around the world. In Europe, Prius sales have rocketed, climbing from 8,136 units in 2004 to 18,886 in 2005—an increase of 132%—and are forecast to exceed 25,000 units this year.
The results of the International Engine of the Year Awards 2006 were decided by a panel of 61 automotive journalists from 29 countries. The awards have been held since 1999 and reward the best engines available on the market. Every engine in mass-production installed in a production car on sale in more than one country is eligible. There are 12 categories to distinguish engines by size, fuel economy and performance.
