According to Toyota CEO Jim Lentz, you won’t have to wait long to see the next generation Prius.

Lentz wouldn’t give specific timing about the debut of the new hybrid, but was clear that the car will be unveiled very soon. This comes as a slight surprise as some have suggested that the new Prius would be delayed in order to accommodate a last second redesign.

The Toyota exec explained that the last three generations of the Prius have averaged a six-year life cycle and the current model was introduced in 2009, suggesting that the fourth generation is coming in 2015. Expect it to debut this fall at the Tokyo or Los Angeles auto shows.

“I have driven it. It’s fantastic,” Lentz said, adding the new Prius will feature a stylish new design and handling due to a lower center of gravity.Interestingly enough, Lentz said that while the 2016 Toyota Prius will indeed achieve better fuel economy than the outgoing model, the estimation of a 15 percent improvement is a bit too optimistic.

Developed in Japan, the 2016 Toyota Prius will be the first vehicle from the automaker to use its new Toyota New Global Architecture or TNGA.
