19.2, I drive pretty aggressively and on sport plus most of the time. Currently running an Intake, Catless Downpipe, JB4.

I'm thinking there must be something wrong with my M235i. Its my first tank and driving 95% in Eco-Pro mode and 5% in Sport mode it shows an average of 13.6MPG. I do live in Los Angeles and my whole 8 mile (each way) commute is up and down hills and all 'light to light' but that seems extremely low. I also have all systems checked with regard to Eco-Pro efficiency settings. Anyone else in LA driving all city streets?

I drive in "fun" mode too, but interestingly enough, here up in North Scottsdale, we have straight stretches of road at 50mph speed limits... I'm getting 26.5 mpg ...

@turnstile ... It's the hills that really mess you up. I think the way the car gets great mileage is from coasting(Car goes neutral and also picks up crazy speed downhill) and also from Start/Stop(but this never adds to your mpg because you are not using gas nor are you moving). I drive from Santa Clarita to El Segundo daily and I get incredible mileage. Next time to help you out, make sure Coasting is on and complete release your foot off the gas when you're going down hill. This will help you tons with mpg. Take advantage of those hills! Let me know if your mileage increases.

Thanks for the tip. I do have coasting turned on, and I do remove my foot from the gas pedal so... My previous M3 got 12.5-13 around town, which was one of the main reasons I decided to go with the M235 instead of an M3/M4. I'd be happy getting 18MPG around town, which I thought would be very realistic for a car that stated 22/city. Perhaps its lousy fuel the dealer filled it up with? Im going to fill it up with 91 and run another tank and see what that amounts to.

Start/stop may not improve instantaneous MPG (because you can't measure it), but it does improve average MPG.

Up to just under 25mpg now, avg, 90% highway.

I'm sure that will go down a bit for a while given that I gave the car some goodies

It shows an average of 13.6 mpg you say.. but have you actually computed it when refilling? I have been brutal on the car and I have never dipped below 18mpg (over a tank).. the instantaneous average would be something else!

[kerm1t]

same. eco pro or not theres literally only 1-2mpg difference. i avg 22mpg. im in socal as well

I did, and the calculation came to 13.7mpg. I just filled it up recently, drove a 1/4 tank (all Comfort mode), and am getting 15.4mpg so far. Thats with a very light foot. This seems incredibly low.

[HX_Guy]

Yeah that definitely doesn't seem right. What was your average MPH? Are you doing a lot of stop and go or idling?

I got 14.5 my first tank and then it kept improving. I'm up to 19.6 avg now and 80% city in sport mode with manual transmission.

My whole drive is stop and go surface streets. Up and down hills. I guess I'll have to run a few tanks and see if the mileage improves. I'd drive it in manual/sport 100% of the time as long as I could get 16+ mpg. My previous M3 got around 12.5mpg with the same commute. EPA city estimate for that car was 14mpg. Go figure.

No. I got around 178 miles from my first full tank. That was using Eco-Pro most of the time.

[pikcachu]

I'm getting around 23 after 3000miles... not much freeway but not stop and go city either

[ciwhamc]

I have had a full commute week. I am getting about 31 mpg on my way to work and about 25 on the way back. (More city on the way back). If I can keep this up it will save me about 130 a month in gas over my last BMW.

[Glassjaw047]

after 1,100 miles, average mpg is 19.7 with an avg mph of 25.6. I just reset my mileage gauge in the odometer area. The Average MPG # keeps going up and up since getting the car. It's started at like 13.4 mpg on avg.

[XxDanoxX]

Surely you don't buy a 3 litre, 6 cylinder, twin turbo, petrol car ....and then start talking about MPG??

In the UK we pay the equivalent of $2.20 a litre ($10 a gallon) for petrol too!

Just to get in on this particular action though, 325 miles Eco, 230 miles Comfort/Sport driving and having fun.

My take on this, unless it's nose to tail or you're in a built up area don't sit in Eco all your lives, think of the amount of money you've spent on a car you now drive like Miss Daisy!

I'm getting about :

-22-25mpg with sports chassis mode
-20-22mpg with sports+ mode


90% highway 10% city driving
