Hey everyone,

I just got back from driving my car, and I'm averaging 25.4 mpg with mixed freeway, city, and stop and go traffic with the Mazdaspeed 3 2.3L Turbo. Best I've ever seen for average on my car is 27.8 mpg, after driving for about 1 hour on the freeway at 55 mph!

What do you guys and gals average with your cars?

 

That's not bad, really, because I'm sure no one who owns a Speed3 is going to drive it like a grannywagon and expect 40 MPG.

My 3i Touring is almost to 2000 miles and is averaging a shade over 31 MPG city/highway. Oddly, the harder I drive it the better my mileage seems to get. The engine must be more efficient above 3500 RPM. [sm=icon_rofl.gif]

 

Iagree w/Greg. The harder I seem to drive my 2.3L (within reason of course,) the better the mileage.Weather, and air density seem tohave an affect on that though too.
I average 26-28mpg w/o the A/C (more on long trips... 32-33,) and 24-26 w/the A/C and whenever traffic allows, shiftingat +4~5K!!

 

My 4dr 2.3 getsabout 22mpg. I drive fast,and it's the winter, so i have the heat on, and the colder air gives you better performance but sucks up more gas. The car feels more torquey, which i love. I live inpretty much a country settingwith roads that are 55mph withfew traffic lights.I do commute to school about 15miles away, and there is a lotmore traffic in that area,so i'd say a mix of highway and city. I tend to have a heavy foot and i go about 70-90mph on a few of the roads to school (I know where cops hide.) They're two lanes, so i have room to do it. When i get on the interstates, then I'm between 80-100mph, so it's better for me not to drive on the highway. I know this sounds bad, but i can't help it. The car handles and drives amazingly at these speeds. SometimesI look at the speedometer and see how fast I'm going and don't realize it. In the summerI get about 25mpg, same driving habits.

 

With less than wonderful winter gas out there, and my engine going through warm-up-from-cold cycles, my mileage has slipped the last few months, down to the 27-29 range (mix of city/hwy, not a whole lot of stop and go). Outside of winter, I do 1-3 mpg better, without A/C usage.

 

I'll have to pay a little more attention to the temp/humidity from now on to see how it affects my car. Though I don't think it's changed much over the last month; the car actually turned in its best tank (just under 32) when we had our coldest weather. But still within the break-in period, so that counts as anecdotal evidence. The car really does seem to have a "sweet spot" where higher revs don't hurt the MPG, until you get above 70 MPH and air drag starts to bring it down again.

 

because of all the highway driving im doing rightn ow its looking like 4.7L per 100 KM. then i hit kitchener and the 401 and it ends up going to hell from the traffic lol

 

I'm not a metric expert, so these calcs could be wrong ... 4.7L is 1.24 US Gallons ... 100 KM is 62 miles ... 62 miles divided by 1.24 US Gallons is 50 miles per gallon. Your getting 50 miles per US Gallon? Are you driving downhill with a tail wind?

 

Lol, no one ever said Jaimie would win the Nobel Prize for mathematics....

 

IDID the conversion/calculation and Uber is right!! 50.05mpg.

Jaimie, Jaimie, Jaimie. That's impossible.You're doing something wrong w/you calculations. You ain't driving a Prius y'know... and they only get around 45(?) iirc.

"Are you driving downhill with a tail wind?"

Yeah, Ube, he must be!! BOTH ways!!Or, he's got the slickest 3 sedanI've ever heard of. How many coats a' wax you got on there, Boy?? [sm=lol.gif][sm=lol.gif][sm=lol.gif][sm=lol.gif]
