This is the 2010 Toyota Prius, featuring 1.8-liter inline-4 with variable intake valve timing — 98 hp at 5,200 rpm and 105 pound-feet of torque at 4,000 rpm. More pictures and a video after the break.

“Running on the Atkinson cycle, the 1.8-liter is the single biggest factor in the 2010 Prius’ climb to the coveted 50-mpg combined rating (from 46 mpg in 2009).”
