Sedan to Get ‘Highest Fuel Economy of Any Vehicle Without a Plug’
With a re-engineered 1.8-liter engine boasting “unprecedented” thermal efficiency of 40% and a new full hybrid powertrain, the 2016 Toyota Prius will have the “highest fuel economy of any vehicle without a plug,” the automaker said today, releasing additional detail on the new sedan model.
“Full hybrid system components have been made smaller and lighter, including the electric motor, transaxle, power control unit and hybrid battery,” Toyota says.
A planetary gear arrangement has been replaced with parallel gears, and there is a 20% reduction in mechanical losses through friction.
Collectively, the driveline improvements generate “an expected 10% improvement in EPA estimated MPG on core models, with an Eco model that will achieve an even greater improvement.”
The 2016 car will have newly developed lithium-ion or nickel-metal hydride batteries. They employ established technology, Toyota says, but energy density has been improved so more power can be obtained from a smaller unit, relocated beneath the rear seat to increase cargo space.
“Prius, which means ‘to go before,’ changed the way we move about the world, and changed the automotive industry forever,” Toyota says.
Today, after more than 8 million Toyota hybrid sales worldwide, “the all-new, no compromises 2016 Prius stands side by side with its sibling, the hydrogen powered Mirai, poised to change the game yet again.”
The new Prius is to arrive in dealerships early next year.
Toyota has yet to release details of the plug-in version of the 2016 Prius sedan. Next year’s larger Prius V and smaller Prius C vehicles will remain largely unchanged.
