“The current Prius has held America’s fuel economy crown for many years,” said Ogiso. “In its three generations, Prius MPG has improved on average by about 10 percent, each generation. The challenge to continue to improve at this rate — to beat your own record — becomes very difficult, but makes it all the more motivating. We are very motivated to beat our record.”

The next Prius will feature improved batteries with higher energy density – the relationship between the battery’s output and dimensions. Toyota, already a leader in advanced drive battery technology, has stepped up its research, development and production capacity of both nickel-metal hydride and lithium-ion and will use these technologies where appropriate in its expanding focus on electrification of the automobile. Toyota has also ramped up development on new battery technologies like solid state and lithium air, as well as devoting resources focused on chemistries beyond lithium, such as magnesium and other low-valence materials.

The next Prius will also feature electric motors that will be smaller in size. He noted that the current Prius motors have four times the power density of the first model and that “the next will be even higher.”

In addition, the thermal efficiency of the gasoline engine in the current Prius is 38.5 percent. The next-generation will boost that level to more than 40 percent – a world best.

The next Prius will also utilize Toyota New Global Architecture (TNGA), featuring a lower center of gravity and increased structural rigidity, which will contribute to greatly improved driving dynamics.

Improved aerodynamics will contribute to an all-new exterior design. Ogiso promised a roomier interior and significant refinements in design, layout and ease of operation.

Ogiso also said the next-generation Prius Plug-in (PHV) is being developed in parallel with the standard Prius model.

“We have been listening very carefully to Prius PHV owners and are considering their requests for additional all-electric range. We have also heard from owners that they would like a more convenient charging operation,” Ogiso said. “In response, we are developing a new wireless/inductive charging system that produces resonance between an on-floor coil and an onboard coil to transmit power to the battery, providing charging without the fuss of a cable.” He said verification work on the system will be conducted in Japan, the U.S. and Europe in 2014.
