Toyota said on Monday it expected to have 21 hybrid gas-electric models like the Prius in its line-up by 2015. Of that total, 14 of the new hybrids will be all-new, the automaker said.

Toyota has previously said that it expects to have a hybrid variant available for every vehicle it sells. In a gas-electric hybrid like the Prius, a battery captures energy from the brakes to provide a supplement to the combustion engine, boosting overall mileage, particularly in stop-and-go city traffic.
