2012 Toyota Prius v Wagon Five 4dr Wagon (1.8L 4cyl gas/electric hybrid CVT)
Trip To The Grand Canyon From San Anotnio
 I bought my Prius V Five in April. My son and I drove to the Grand Canyon from San Antonio this summer, in one week we added 2,500 miles to the car odometer. Highway speed limit at places are 85MPH and driving in the park 20MPH. I averaged 42.5 MPG on this trip. By the way I had no trouble driving at 85MPH on IH10 or IH20 in West Texas. The car handled very well and kept up with all the other traffic on the highway.
