I was quite happy that I could get 41 MPG "combined" given it was the first time I was in a hybrid vehicle and all.Figure about 36-37 mpg (my experience at those speeds over long distances, varying terrain) x 14.8 gal (US) = 532 to 547 miles to empty.
Perfect conditions that you describe, my experience is about 40+ mpg, so 592 give or take.
Your mileage may vary.
Love the radar cruise control feature. Not sure if that or regular cruise control is better for mpg, but cruise control in general seems to give better mpg overall. I suppose the radar cruise control might be a little better because you aren't disengaging/re-ingaging so much so it's a little smootherI'am gonna warm the engine with an electrical heater before every ride also.
This will be my first vehicle with ACC also (fantastic system btw), generally speaking is it fuel efficient to use ACC or should I revert to normal CC or just manual throttle control?
