Since 1997, ore than two million Toyota Prius hybrids have been sold and more than 97 percent of them are still on the road. Two electric motors and a 1.8-liter four-cylinder engine deliver a combined 134 hp through a final-drive ratio changed from the standard Prius's 3.27:1 to 3.70:1. Estimated combined-driving gas mileage falls from 50 to a still-impressive 42 mpg. A maximum of 34 cubes of stuff will fit behind the second row, nd 67 can be accommodated with those seats folded. Extra-long rear doors and a roof raised by 3.3 inches provide ready access to back seats that slide 7.1 inches and fold on a 60/40 split. The second-row backrests adjust 45 degrees. The V's structure is sound, hrewdly tuned dampers do a commendable job of managing body motion, nd new dual-path front-strut mounts eliminate some of the standard Prius's impact harshness. Awesome audio sound and bluetooth enabled to take control your phone upon entering the car. Oh, an keep your keys in your pocket with its keyless ignition.
