I bought this car 2010 prius few days ago. I reset trip to see my results.currently iam driving in london city area.iam not happy with mpg 39 avg.
39 isn't much below average. stop and go traffic takes a tremendous amount of energy to repeatedly get the car moving from a standstill. best to measure your mpg's at the pump and calculate average over many tanks. what types and pressures? clean air filter? hvac use? 12 volt and hybrid battery condition?
Ensure you're all updated on maintenance and try the pulse-and-glide method. I can get 65 mpg in both our Prius and my wife's Corolla Hybrid. Ahmed (The Care Care Nut) explains it in this video:
It seems like you are not getting enough speed to produce good regen. It seems like most of the engine power is going to move the car so u are burning more gas and not enough to charge the HV battery high enough to get better mpg. Try to get the battery bars to full. Like driving it on the highway (motorway) for a while until bars are at full. Or drive it somewhere at stop and go speeds above 25 mph. Your trip data is showing 6mph and a distance of 12 miles. Which means you drove at a joggers pace for 2 hours? You could also be sitting in traffic a lot or parked while the car was on ready mode for quite some time which would drain the HV battery fast. The car used it all it's EV charge and then went only on gas. Not enough to charge the HV battery to full. But still you got 39 mpg which is still good for your driving situation.
