While its range and efficiency have grown, so have the Prime’s exterior dimensions. Based on the redesigned Prius, the Prime is 2.4 inches longer and 0.6 inches wider than the previous Prius plug-in; it also sits an inch lower. Toyota says the new dimensions improve cargo space and handling, while aerodynamic shaping and automatic grille shutters reduce wind resistance. Moreover, weight savings come courtesy of an aluminum hood, carbon-fiber elements on the rear hatch and high-tensile steel in other areas.
Inside is a cabin-dividing center console, standard 60/40-split folding back seats, standard heated front seats available in synthetic leather, automatic climate control with targeted airflow for maximum efficiency and a smartphone-activated climate-control mechanism that enables the driver to cool the cabin remotely before getting in the car. Other interior features include an 11.6-inch touch-screen for the Entune infotainment system, dual 4.2-inch color displays in the gauge cluster and sound-insulating-laminated glass to reduce wind noise.
The Prime will be available with intelligent parking assist, which parallel parks the car or backs it into a space automatically when activated. Advanced safety features will be packaged in the Toyota Safety Sense suite, which includes emergency auto braking with pedestrian detection, lane departure warning with lane keep assist, adaptive cruise control and adaptive high beams; other safety features include a backup camera, blind spot monitor and rear cross-traffic alert.
