TOKYO (AP) -- Toyota has developed an efficient gasoline engine using technology fine-tuned with gas-electric hybrids, where the Japanese automaker is an industry leader.
Toyota Motor Corp. said Thursday the engine will be rolled out in 14 models this year and next year.
The technology is common in hybrids, such as Toyota's Prius and Ford's Fusion, which switch back and forth between an electric motor and a gas engine for better mileage.
Bu it is relatively rare in vehicles running on gas engines alone.
Japanese rivals Mazda Motor Corp. and Honda Motor Co. have developed similar engines.
Toyota said the new engine will deliver 10 percent better fuel efficiency than comparable current engines.
It uses an old-style engine type called the Atkinson cycle. Toyota said its development achieves efficiency without sacrificing power.
