T1,
I make that 19.7km/litre.........

(unless I did the division wrong way round, in which case it’s 0.052km/litre

) And you’ll probably improve on that by keeping the battery charged and in use.
That’s even better than our Baleno’s consistent 17.4!
Ours is a 1.1litre turbocharged 6-speed Auto.
What’s the Prius’ engine/gearbox configuration?
1500cc petrol throttle body injection Atkinson cycle engine, single speed 2 electric motor/generator all permanently coupled to a planetary gear set. The computer determines what sections turns at what speed depending on conditions. Above 38km/h it spins the engine to avoid over speeding number 1 motor/generator but only supplies fuel when there isn't enough drive available from the electric motors/battery. Fascinating watching the display that shows just what is doing what at any given time, it will switch between 2 electric drive on battery power to 2 electric drive plus petrol engine power under high load, then change motor/generator 1 into a generator to use excess power developed by the engine while operating at its best efficiency, then cut the petrol and run on 2 electric motors again, then turn both electric motors into generators for regenerative braking if there is a slight down hill run or when slowing the vehicle.
The latest acquisition will actually travel in all electric as an option, recharging the in vehicle battery from the added battery pack until that battery pack is depleted, then it returns to normal hybrid operation.
The fellow we bought from had 1865km recorded from half a tank of fuel or 1.07ltr/100km because he had a relatively short commute as far as distance, but an hr or some actual travel time, so the majority of the time it ran in electric vehicle mode, only using the petrol engine where a hill start from traffic lights or out of a corner was involved.
I got to drive it today in electric vehicle only mode, it made it up the Mannum memorial hill while still maintaining the 50km/h so I'm really happy with that. Margaret drove it yesterday and took the back road that has a long hill immediately after a sharp left hand turn. It drove over the hill but struggled to hold 25km/h on the steep bit. The 2 electric motors can only produce around 20kW of drive power and although that is from a stand still start through to 86km/h I believe (haven't tried that out yet) it isn't a steep hill climber without a bit of a run up

In blended mode as they call it, it eats any hill and overtakes like a much more powerful engined vehicle.
