All Prius Prime models
combine the same front - drive layout, an 8.8 - kWh, 265 - pound lithium -
ion battery pack with an EPA range of 25 miles, two electric motor -
generators, and the «bridled fury» of a 95 - hp 1.8 - liter Atkinson - cycle inline - four gas engine (descriptor courtesy of Car and Driver).
