I didn't see an MPG thread for Q50 Gassers so thought I would start this one. If there is one, pls move this post.

Just finished a 2500 mile road trip from San Diego to Estes Park, CO and back. The outbound portion took us to Monument Valley and Arches National Park in UT. The trip back was more direct but had 6 hours of challengingrain.

The trip involved all kinds of highway traffic including high power passing on 2 lane roads and over mountain passes (Rocky Mountain National Park in CO) as well as sight seeing slow speeds.

The final number is 30.36 MPG. Pretty good for a 3.7L gasser.

Intelligent cruise control and lane departure control used extensively.

Thats alot better than what I got on my 1150 mile trip. I was averaging around 23-26 mpg. But then again I was fluctuating alot between 65 and 85 mph since our speed limit up here is only 65 upstate. 55 in the boroughs of NY.

What grade fuel were you running?
Was running 91 octane from 1st and 2nd rate gas stations. I didn't want to chance a lower octane knowing some of my driving was going to be at 10000+ ft altitude.

I am kind of surprised the car did as well as it did. My driving was hardly optimal in several different conditions (rain, lots of hills, slow/passing traffic, over mountain passes, etc.).

hwy no traffic. best i can get is 31
That is pretty good for a 330 HP engine. I am pretty happy with 30.3 over 2500 miles.

Even though I tried not to top-off any of my fills, some stations fill up the tank a little more than others. That is why I wanted to test over several fill-ups when I knew I was going to be doing 85-90% highway miles.

Most of my driving recently has been stop and go rush hour traffic. I'm at 18.8 mpg this tank according to the computer. Pretty disappointing. I haven't even been driving it hard.

That's what I have since I bought it early October (20 - 23 mpg). I now have around 1500 miles. My driving is mostly highway but during commute time is stop and go traffic for 25 miles.

Mostly I set it to standard and try to set it to Eco. I do notice that the mileage went to 23 once when I set cruise to 75.

Does the break-in period have anything to do with it?

Good to hear there is someone who gets to 30 mpg. That is amazing this size of engine.

On a trip from Miami to Orlando, I averaged 28.4 mpg, with an average speed of 75 mph. Icc was set between 75 and 80. Though I did have a few burst of 100+ mph.
This car is really decent on gas if you aren't too hard on it. On the contrary, the worst I've gotten was 16.8 mpg on a tank. btw, I have a fully loaded gasser.

I'm travelling daily in almost constantly stop and go traffic and see about 16.8 - 18 mpg, usually in ECO mode.

My thinking is that ECO mode just shifts earlier to work the engine less (ie keep the rpm low), but I'm not sure how much extra mpg you get above standard mode in stop and go traffic.

I think you might be right. It shift quicker to 7 when in ECO mode.
My mileage is similar to you when I am driving in heavy traffic in Highway (under eco mode). Good to know that it is not only me.
