Spy shots of the redesigned Prius, plus a rendering

Ever see a car smile? It sure looks like that's what this redesigned Prius is doing testing out in Death Valley, as captured by KGP Photography and posted to Jalopnik. The vehicle as seen is not all that different from the current Prius model, just with a grinning grill and some changes to the headlights. Toyota is working on a redesigning the current model before the (delayed) next-generation Prius hits the streets.
While this smiling tester gives us a glimpse into the near future, ABG reader David has give some thought to what the next-gen Prius will look like. Click on the photo at right to see Jalopnik's gallery of new Prius spy photos.
