In August 2013, Toyota Managing Officer Satoshi Ogiso, who was chief
engineer for the Prius line, announced some of the improvements and key
features of the next generation Prius, expected to be introduced as early as
2015.[66][67]

The next-generation Prius is being designed to deliver significantly
improved fuel economy in a more compact package that is lighter in weight
and lower in cost. These objectives are being achieved through the
development of a new generation of powertrains with significant advances in
battery, electric motor and gasoline engine technologies. The next Prius
will feature improved batteries with higher energy density; smaller electric
motors, with higher power density than the current Prius motors; and the
gasoline engine will feature a thermal efficiency greater than 40% (in the
current Prius is 38.5%). The Prius fuel economy has improved on average by
about 10% each generation, and Toyota has set the challenge to continue to
improve at this rate. The next Prius will feature the Toyota New Global
Architecture (TNGA), which provides a lower center of gravity and increased
structural rigidity. These features, along with other improvements will
allow for gains in ride-and-handling, agility and aerodynamics. The improved
aerodynamics will contribute to an all-new exterior design, which includes
a roomier interior.[68][69]
Ogiso also explained that the next-generation Prius plug-in hybrid vehicle
is being developed in parallel with the standard Prius model. Toyota is
developing a new wireless or inductive charging system that produces
resonance between an on-floor coil and an onboard coil to transmit power to
the battery. The company plans to begin testing of the wireless battery
charging system in Japan, the U.S. and Europe in 2014 for a future plug-in
Prius. Toyota is also considering requests from Prius PHV owners for
additional all-electric range.[68][69] | y****3
