2018 Ridgeline Touring
It sounds like my 2018 is doing pretty good, judging by this thread. I live in the country and it's almost entirely highway. Mixing backroads, occasional in-town and highway, right now in the winter when it's averaging like -10C, I get around 19.8-20.5 mpg. On highway driving, even when it's this cold, the dash says 25 mpg. I know the dash can be a little optimistic, but this makes me feel good for when it's warm out, I might even get below the hallowed 9.0 L/100km!
