I'm in a Prius taxi. This company operates a fleet of Prius taxis, running 24/7. The driver tells me they get 45-50 mpg. No Prius in their fleet has needed a new traction battery before 250K miles. A replacement battery costs them $1800, or they may change the whole drivetrain. The highest mileage Priuses in the fleet have 400K miles. There are a few 2010+ models in the fleet too.
