The all-new 2010 Toyota Prius offers no surprises, just significant improvement. It's sleeker and better looking, and more powerful while delivering an EPA-rated 51/48 mpg City/Highway, up by 3 miles per gallon.
The hybrid mechanicals are lighter by 65 pounds, while being more
efficient and presumably stronger. The 1.8-liter gas engine is also
new, producing more horsepower while being more efficient. Top speed
has flown to 112 miles per hour from 103 mph, slam-dunk evidence that
the Prius is a lot slicker package at half that speed.
