I heart boat tails:
That's one way: secondary highway route, cruising at/near the limit of 80 km/h / 50 mph, going through 2 small cities, with lots of engine-off coasting to stops turns, plus speed zones through multiple small towns.
(Yes, I'm such a nerd that I'm posting my fuel economy from a cottage in the middle of the weekend... though in my defense, it's raining at the moment. We just beat the rain back to the dock!)
My previous best for this leg of the trip is high 90's, if memory serves. Will confirm when I get back.
EDIT: wrong - previous best was 103. See below for more details on best & average MPG for this trip which I've been taking for several years in the Insight.
