All-New Prius Boasts More Advanced Technology
What’s going on with the new Prius’s technology? For starters, Toyota says the all-new Prius has the highest fuel economy of any car without a plug. The 1.8-liter four has been redone and now has 40 percent better thermal efficiency. The hybrid system (electric motor, transaxle, power-control unit, battery) is smaller and lighter, and Toyota says it expects a 10 percent mpg* improvement, minimum.
Prius Engine Redesign
The displacement stays the same, but the engine is redone with improved combustion efficiency, a redesigned air intake port for better combustion-chamber airflow and lower-friction pistons. Fuel economy is also boosted by an active grille shutter — it opens and closes as needed, depending on temperatures. Toyota didn’t give system-horsepower numbers, but we hear it’s in the 145 to 150 range, up from today’s 134.
Toyota says the redesigned transaxle and electric motor are lighter for a better power-to-weight ratio. Parallel gears replace the planetary gears in the reduction gear, and the power-control unit is smaller.
Prius Small, More Powerful Batteries
The Prius is available with either a new lithium-ion or nickel-metal hydride hybrid battery. While the batteries’ technology carries over, Toyota says it increased their energy density for more power from smaller batteries. Being smaller (again, it didn’t say how much), they’re now relocated under the rear seat, increasing cargo space.
Prius Improve Handling
Toyota says the new Prius handles better thanks in part to a 60 percent stiffer chassis. The platform is laser-screw welded, and there are more structural adhesives throughout the frame. High-tensile-strength steel use is up from 3 percent to 19 percent.
The all-new Prius has a lower center of gravity. It’s three-quarters of an inch lower in height, and the nose is almost 3 inches lower. Combine these changes with the car’s new double-wishbone rear suspension and hybrid-system software updates for better throttle response, and Toyota says the result is a sportier Prius.
