Toyota has developed an efficient gasoline engine using technology fine-tuned with gas-electric hybrids, in which 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 the Toyota Prius and Ford Fusion, which switch back and forth between an electric motor and a gas engine for better mileage. But it is relatively rare in vehicles with 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.
