10.6 Perth to Dunsborough (Margaret River). Peak traffic on the freeway southbound 110km limit after. XC 90 no better. Would suspect Prious slightly better but no comparison on the drive and zero overtaking ability. Kids enjoyed M3 audio. Very loud. No fighting and no eating. Xc 90 always a mess. My point fuel nit really a factor unless on the track. Kids love it. Fantasic drive any conditions. Conclusion: don't by a Prius or anything recommended by greens.
