We just returned from a 900 mile trip from the bay area to LA area this past weekend with 4 people in our HCHII. The trip was long enough to test out the capabilities of a fully loaded civic on a very long stretch of interstate (I-5) and then some steep climbs and declines. The trip down to LA was in the morning on a Saturday (light traffic) and the return was the middle of the night. Temps were between 40 and 50.

We averaged for the entire trip 39mpg. We averaged down (41+) and up (37). As far as comfort, I'm used to a large Odyssey ride but this trip proved out that the seats were comfortable - though a bit cramped for our rear seat passengers. The return trip was 6 hours solid with one stop for a double shot at Star bucks.

I'd have to say, 39 mpg is darn good for 900 miles at roughly 73mph. I used cruise control for a lot of the trip. My alternative vehicle would have been a 04 CRV which likely would have averaged 23mpg fully loaded so no complaints here! This civic handled the windy conditions over the pass north of LA and the long cruise - though rough highway bounce the car around - but again, this is no 4000 pound v6!

I'm happy!
