Today I managed to do this - 50% of it is in city traffic. 20% on the autobahn - because of heavy traffic (regulated by electronic speed limit indications) and short distance, never drove faster than 100km/h. It was a nice 18C. It includes this morning commute as well, and though I got lucky with a pair of traffic lights, I was also a couple of times in a traffic jam. Well - what to say? with the fuel prices we have here...thank goodness I have a Prius!!!
I got 64.1 mpg (MFD) on my round trip commute and I'm trying to see if I can get this tank to be a real 60 mpg calc'd. My last tank was 58.9 calc'd.
