I'm averaging about 19.5 with no highway driving. I drive the heck out of it. No compaints from me. I LOVE the way this car drives. I have tried Eco mode but the car is a temptress; it make me feel like a young man again. My wife drives our BMW now which gets about the same gas mileage without near the performance.

The system tells the owner how many miles the tank has left in it. Fill up the car and look at the fuel consumption screen on your nav. "Cruise miles" tells us how many miles are left in the tank.

Added the photo with all the detailed info. Keep in mind this was only a 184 mile trip, it might of gone up if it was all highway. Also keep in mind this is the AWD model.

My only problem is I don't have one yet. Still tring to choose between the 350 and 450h. So, what are people getting in terms of miles to the tank???

I average a little under 300 miles per tank on 100% city driving, but I fill up early usually.

Take the mileage and multiply by the size of the tank.

yeah, is it very congested these days. COE is at record high now though

I'm still on my first tank of gas (new from the dealer w/ 8miles), and have racked up around 220miles, and still have about a 1/2 tank left. Granted I drive on ECO about 85-90% hwy @ 65-70mph on cruise, although I've put it in Sport+ and have given it a few punches. So I'm guessing it's pretty good so far!
