Toyota today released more information on the redesigned-for-2016 Prius, shedding a bit more light on how the best-selling hybrid intends to achieve that anticipated 10 percent fuel-economy boost. Though official EPA figures are still not out, Toyota said the new Prius’ body and powertrain components are lighter.

The new Prius uses a re-engineered version of its 1.8-liter four-cylinder gas engine, from which the automaker promises better performance and mileage. The transaxle and electric motor have also been redesigned to be more compact and, as a result, lighter, while a 20 percent reduction in friction losses and reconfiguration of the gears has enabled an improved power-to-weight ratio, according to the automaker.
Two newly available batteries — a lithium-ion battery pack and a nickel-metal-hydride one — have increased energy density and are more space efficient than the outgoing units; Toyota says they now fit beneath the rear seat, increasing cargo space.
Horsepower figures have not yet been announced, but Toyota says much of the gas engine’s purported performance boost is achieved through temperature control measures. For example, a new exhaust gas recirculation system provides more thermal efficiency, and a redesigned air intake port improves airflow inside the combustion chamber. In addition, friction between sliding engine components has been reduced. Toyota also said software updates will improve acceleration feel.
