Fuel Economy

Anyone else surprised by the fuel economy on the sport/n-lines? They advertise 9.2L/100km combined fuel economy (30 ish MPG), but I've been getting closer to 7.2L/100km (39MPG) with mixed back road driving and some stop and go. I didn't buy the car because of its fuel economy, but nonetheless happy/impressed with it.

According to the onboard computer I'm averaging right around 30-31mpg. I've never validated these numbers.

Wow. I wish I got anywhere near that combined. On highway I do see 31-32MPG, but my average is closer to 21MPG. I do mostly stop and go city, though. I don't baby it anywhere, either, so that doesn't help.

I had calculated my last tank. Computer was reading right around 32mpg. I calculated 31.6mpg. Mostly local driving and I'm a bit heavy on the gas pedal. Better mileage than I expected. I have the DCT trans.

At just over 10k miles I've averaged 29.5mpg according to the computer. I drove a mix of highway (with 30% stop and go traffic) and urban city (stop signs every block, traffic, lights, etc.). I've noticed that when using the smart cruise control over long distances, the economy is quite good on the highway, even at higher speeds (~33mpg). I have a DCT sport with tech.

I consistently get 37 mpg on the freeway. That's the on board computer number. Even if that number is high, which I'm sure it is by a couple mpg, real world mpg in the 35 range is a nice bonus.

I mostly commute in dense urban rush hour traffic.

About 100km a day in Toronto.

I'm sitting around 8.5/9L per 100km

I'm also WOT throttle whenever I can be, and it doesn't seem to change these numbers too much.

How many miles are on your Elantra GT?

Hopefully over time MPG's still stay consistent with the recommended maintenance.
