I agree with you to a point. Most of the time I'm thinking about what needs done and the time to get that accomplished so time = money. One day I hope to move to the right lane and be carefree but not now. I do the like power of the CX5 for a daily driver but with all the R&D I find it hard to believe they can't get better mpg. Prior to this I had a 2018 F150 with the 10 speed TTV6 as summer truck
2 years in a row I drover from PA to OBX and got a displayed reading of 25.5mpg. It would have been even better if I did it by hand I bet. The kicker is for fun I ran it at the strip and ran 14.9 @ 92 with a 2.0 60' time. Sometimes I think if I would have kept the truck I'd get better mpg overall for daily driving.
25.5 MPG on the LOM is good on a truck. Did you ever hand calculate your F150? My Dodge Ram LOM varies up to 5 MPG! The Mazda 1.5 MPG is the most I've observed so far. Normally it's .5 less than hand calc. Yesterday I drove my 2500 truck 180 miles. LOM said 30.1. Hand calculated said 24.9. Popped my balloon! Still not to bad for a 6500#, old technology, 2006, brick.
I use to justify fast driving in the name of making a buck. I used it as my excuse to drive fast. Latter, I ran out the time savings over a 100k mi on my truck. Stuff like going a 100k mi on brakes instead of 40K and 80k mi vs 40K on tires. The time I lost taking my truck in to get tires, do brakes and so forth off set my fast driving many times over. My long haul truck driver gets to his destination as soon as the faster drivers. He goes 30% further between fill ups. He catches the faster drivers just on fill ups. When I looked at the time/cost over 1 year or more, slow driving saves $$, I have more time and feel better. It definingly requires conscious and deliberate driving habits.
We get 23 to 25 MPG in town driving with our CX 5. Lots of short trips less than 10 miles and over steep hills. As mentioned, 31 to 33 highway.
From what I've read, our Cx5s FE is inline with the other crossover gas burners. Like you I was surprised when I put a pencil to HP/Liter on our NA 2.5l. It's not as efficient as a Dodge 6.4l push rod Hemi. That is, our 2.5s make less HP per liter than the Detroit push rod V8. Popped my Mazda balloon. I STILL like our CX 5 and baby 2.5l engine. The over all package is good.
I've done a few bolt on mods and bought a tune. The mods are simple stuff I made. Turning vane in the fist elbow off the air filter box. CAI with back flow damper on the side of the air filter box. Grounds on the cylinder head and trans. I logged WOT before and after on each of these mods to confirm the gains. FE shows these mods work.
The ECU tune helped FE and added 60 HP. It added power right were it's useful. Even with the tune, the car is no hot rod. I don't get any pleasure dogging it. My last street legal hot rod would spin the tires on a down shift at 60 MPH. It was a handful, begging to be mistreated.
We lowered the car about 1.5" with coilovers and put lighter, spun forged wheels on it. The wheels are about 30% lighter than the factory wheels. Both help FE and handling. It has a look but doesn't scream tuner car.
I swapped out the factory sway bars and bushing for aftermarket. This holds the car steady going down the road. It handles much better and less sway translates into better FE.
Today we got a block heater kit. I'll install it next week. Pre heating will help FE and reduce engine wear. I found a surplus Mazda kit on eBay. $60.
All the mods turned it into this CX 5 into a fun sport crossover that is FE.
