If I drive a lot in towns and cities, my '21 Turbo gets like 21.5 MPG or 22 MPG (what the EPA states). If I drive on the highway and leave cruise control on, my gas mileage will shoot up to 27 MPG (what the EPA states). The other day I was able to achieve 28 MPG on a 1.5 hour drive home using cruise control. With the turbo your either in it all the time, or out of it. It's kind of like the Ford Ecoboost where either you are in Eco or Boost, not in between. I drive pretty aggressive especially when people drive slow or are not being safe, and I still get fantastic gas mileage.

 

What is the long term average on your dash readout? My "trip b" was reset 9500 miles ago. It currently sits at 23.5 MPG over that time.

 

For the last roughly 3500 miles it says 22 MPG. I always keep Trip B for my oil changes, and I reset Trip A every time I grab gas.

 

I wanted the turbo, but the wife wanted better gas mileage.
I can say we get way better mileage in the NA than the turbo.
I'm happy enough with power as well, especially in sport mode with the paddle shifters.
Money saved in gas, keeps my wine collection fully stocked for free

 

Not sure why so many don't seem to at least get the same or very close MPG comparing the N/A to the Turbo. MY friend that has one gets almost the same as my N/A . I do notice when I drive his that it goes into boosted psi (very low 1-3lbs at a very short degree of throttle peddles angle. My thought would be to change the input information on the PID form the throttle peddle % position to delay it more. This would make the engine respond more like a N/A for most normal driving but still tip into the boost when your go to a higher throttle peddles %? Just a thought. Maybe This summer I will do a data logging of his ECU and see more information.

 

It's honestly the city driving that kills the mileage in my car with a Turbo. My girlfriend has the NA motor and without even trying it gets 25 MPG in the city, and like 30+ on the highway. However on my Turbo the city mileage barely hits 22 unless I feather the throttle. I will say on the highway with cruise control it did get 28 MPG the other day, which was awesome.

 

This may actually reduce your MPG
The ECU Programming in the MADZA Skyactiv engine is partly developed because most drivers do not drive to attain the best MPG so feather actually cause changing in fueling and timing to achieve a constant engine speed that is mostly using more fuel then simply driving without thinking about trying your best to get the highest MPG. Does that make sense??
Mazda's selling point is the performance of the TURBOCHARGED engine, and they really did not want a N/A feeling on part throttle which may affect review in the negative and results lower sales of the Turb models.

Even the instant MPG is scaled and not actual because you only see up to 99mpg and that is not what the ECU see and could report. It also has a slight delay incorporated which is ever so slight but none the less there. If you monitored only a few PID and retrained your driving technique based on the observation of those PIDs in the ECU you would be likely posting some of the highest MPG with your MAZDA than any other Mazda forum.

For other reading you will not see the MPG average until the engine in the Mazda is fully broken in which is about 25K miles for the Skyactiv engines.

 

I've posted before that I average about 32MPG locally and up to 36 on the highway.
The Mazda MPG digital readout is pretty spot on with my actually calculations, never been more than .1 to .2 off, at least so far.
But my "city" driving is limited to the 25-35MPH in the local city of 7000 people.
Most everywhere else in the state is 45MPH or more and "the city" is only 5 miles away.
I get better mileage with the Mazda than I did with my Honda CRV or Accord.

 

That's interesting. I don't feather it too much but I meant that I try to drive lighter spirited if I'm trying to go for economy lol. I'll try to avoid feathering the gas and see if I notice a difference.

 

Who did you use for your aftermarket remote start? My wife does not like having to log into the Mazda site to remote start her 2021 CX5 Signature.
