First Toyota, hybrid or PHEV. Must say, the car is absolutely fantastic. Comfortable, all necessary accessories, quiet, smooth and most of all, unbelievable economy. The picture shows the MPG figure (Hybrid mode) after 120 miles. The cruise was set on the motorway (highway) for 70 and that was 35 miles into the journey. I even forgot to change it to ECO.... Simply amazing stuff.
74.4 miler per imperial gallon, in use in UK? That would convert to 62 miles per US gallon. Still excellent. And I believe with Gen 5 Toyota has overcome their propensity to exaggerate the mpg?
I’m guessing that your car is a PHEV Prime? I am super happy with my Prime - I have driven 3,000 km after my last fill up 2 months ago and there’s still 1/2 tank of gasoline remaining!
ECO mode isn't going to change mpg much at 110km/h, although at 12C degrees ambient the HVAC settings you used might have contributed some to your amazing picture of your mpgs. Thanks for the picture, it's extremely focused, especially when taken at speed. I ended an 800 mile trip with 72 mpg showing 8 years during springtime too. And after 8 years I'm still happy with our Gen 4 Prime. Even though now at 97k miles it doesn't show mpgs that high any longer sadly, but mpgs are still good, IMO anyways !
