Toyota has released technical specifications of the fourth generation 2o16 Toyota Prius. The 2016 Prius is built on the Toyota New Global Architecture (TNGA) platform. It has dimensions of 4,540 mm (+60 mm), 1,760 mm (+15 mm) and 1,470 mm (-20 mm) in length, width and height respectively; the wheelbase is measured at 2,700 mm.
The TNGA architecture results in the car having a low center of gravity that further results in more stability and minimal sway while driving. Toyota has also increased the amount of high-tensile strength steel used from the previous 3% to 19%. This is expected to make the car safer with better collision safety performance.
The Hybrid Synergy Drive hybrid powertrain will continue with the same 1.8-liter VVT-i (2ZR-FXE) inline four-cylinder petrol engine. It has been comletely re-engineered for improved performance and fuel efficiency though. Power output is now 75 kW (98 PS/97 hp) with peak torque rated at 142 Nm. The electric motor assisting the combustion engine churns out of 53 kW (72 PS/71 hp) and 163 Nm of torque.
The reworked engine is claimed to have a maximum thermal efficiency of 40%, which is the highest in a mass-produced gasoline engine. This became possible by using a large-volume exhaust gas recirculation (EGR) system, a redesigned air intake port, redesigned coolant passages and friction reduction between moving parts. Low-viscosity oil takes care of lowering friction between sliding parts.
The two all-new motor-generators have a higher output density and feature an innovative rolling-coil structure. For the first time, the Prius will come with two battery options – Nickel-Metal Hydride or Lithium-ion; positioned under the rear seats.
Another first, is the E-Four (electronic four-wheel drive) system, which uses a high-output rear motor to assist the engine and front motor. This ensures better grip and drivability under bad-weather or slippery driving conditions. Models equipped with the E-Four system have a luggage carrying capacity of 457 liters, which is the same as the 2WD model.
Safety systems such as Toyota Safety Sense P and Intelligent Clearance Sonar help to avoid collisions or reduce the amount of damage resulting from them. The 2016 Prius also features the latest ITS Connect safety package that allows vehicle-to-vehicle or vehicle-to-infrastructure communication resulting in information that cannot be picked up by onboard sensors such as traffic signal information and presence of vehicles or pedestrians in the blind spots.
The 2016 Toyota Prius will go on sale in Japan in December. U.S. sales will commence in early 2016.
