Low mpg

I would say yes. I have been driving manual for over 15y and was very ineficient (and in a way still am getting used to this new car), also listening to loud music messes up my mpg because I'm not tuned-in to the engine revs. I find that being able to listen to the engine helps you gauge shifting timing better.

I found out that my range goes from 300km to 400km (25% increase in mpg) just by doing a long distance trip (hwy driving in 6th at around 3k)..

I have come to terms with the fact that, a) I do a lot more city driving than I want to, and b) Im really enjoying this car so I'm holding back or trying to be ultraconservative, but I am efficient in using the manual transmission tho. Can't comment on how automatic fares. One thing I am dissapointed with this car is the range, wish the tank was large enough to accommodate 500 clicks. Curious what median and avg ranges other people are getting.

I have only 2600 miles on my car and my MPG is also 24.2

Ive seen it do 25 MPG doing a consistent 125mph for about two hours.

My understanding is that the two systems work in complex synergy. There is no strict cut-off when one is working and the other isn't, except at the lowest speeds. I agree though that their is something about the system that causes the engine to have a huge differential between highway-only driving and ordinary 45-50mph back road cruising.

Try turning your efficiency indicator on which has an arrow flash on the LCD screen when you should shift for the best efficiency.

What Husker741 said. You will see the arrow around 2K. Takes away some of the fun factor but in daily commuting you can only get there as fast as the traffic will allow anyway so alot of the fun factor is gone anyway.

i'm averaging about 22 mpg - 4 miles each way, spirited drive to and from work in traffic. i do no freeway/highway driving.

If you want to see improvement you have to completely change how you drive. Here are some beginner tips:
(1) Don't be in a rush.
(2) Ease away from stop lights. Who cares if you're not the first car across the intersection?
(3) Shifting at 3-4K and you think that's good for F/E?? Try shifting at 2K.
(4) Fuel economy goes down w/ speed *over simplified* so try doing the speed limit or "just" above it if you have to. (PROTIP: police will go after the chumps going by you in the passing lane)
(5) Learn to coast to your advantage. Try and minimize the loss of speed. If you see a slow down ahead, don't fly up to it and slam on the brakes, instead COAST (or use the brakes minimally). Instead of hitting the bottle-neck and coming to a complete stop you may only lose half your speed, etc.
(6) Find a friend who is a F/E whore and ride with them. I'm sure you think you know how to "drive for F/E", but the fact you're doing so poorly tells me that you don't (not to say that you "drive" poorly).

Best of luck! F/E driving can be addicting in its own way.
C'MON BABY GIMME ANOTHER TENTH A GALLON!

Averaging right around 20 MPG I'd say. I like it that way. A few extra bucks a week doesn't matter.

I can get very good highway mileage too at 65-70mph while in 6th on flat highway (35+mpg). The best mpg I got was during my break-in period when I was trying to stay under 4000k.

I can understand that it uses more gas but it also has a variable timing difference at the point D4S kicks in, it seems like an efficient driving style to also let the engine breathe in some cases, as the engine and drivetrain seems to get smoother in a higher rpm range (at the cost of being really freakin loud sometimes.

Shifting below 2500 rpm usually sucks for me because I get a lot of syncro-feel and clicking in the transmission.

Thanks for all the input! And yes, I use the indicator on the car.

I got 26mpg doin 126mph for 2 hours. Got you beat.

I dont even try to drive "light footed" and still get 30 mpg. (all premium gas in my area is 93 octane 10% ethanol)
