I have an early 24, built 11/23, Turbo. No i stop. I can't tell if it has CD.
We took a 1500 mile trip in the CX 5 T last week. 80% interstate through hills and mountains. The remained was combo small towns, windy mountain and some gravel roads. We drove from Birmingham, AL to Charlottesville, VA. and returned through Blue Ridge, GA. Endured Atlanta traffic.
We averaged 31.5 MPG, hand calculated over this trip. The stick says 22/27 MPG.
We ran 93 oct fuel, drove mostly on CC at 67 on the interstate when posted 70. On secondary roads, mostly without CC. Ambient was 65 to 85F over the trip. We let it "eat" up the mountains on CC. Dealing with traffic required slow downs and speed ups. So it wasn't steady state for long periods of time. Drove in the rain the last 250 miles.
I don't remember passing a single Mazda on the trip. Many a CX 5 flew buy me. I smile and remember it wasn't that long ago that was how I drove.
Mods: DRTuned ECU tuning, lighter wheels (40 #s lighter than stock), grounded cylinder head. Tire pressure 36 PSI with OEM Toyo A36s.
I got a revised tune 2/3s into the trip from DRTuned, installed and made a few WOT tests. This tune picked up FE about 1 MPG over the "starter" tune. I requested for David to tune CD OFF.
I've noticed a nice increase in town with the revised tune, +25. 25 MPG in town requires restraint. The tuned 2.5l T is ready to rock!
Conscious driving is good for about 30% increase in FE. Long haul truck drives get a bonus based on their FE. The best drivers get 30% better than the average drives. They drive under the speed limit, stay out of the packs, avoid braking, slow to accelerate, plan their stops and use CC.
I increased FE in my 06 2500 Dodge with a Cummins 5.9 by 30% using the above methods and adding a few bolt on mods. I developed a driving log. On trips I note how many times I have to brake, times I stop, ambient temp, wind (head, cross or tail wind) and so forth. When towing, stops eat into FE. Planned stops where it's easy to enter and exit improves FE.
One mod we added to the Turbo Inlet Pipe, turning vanes. Many owners, myself included, removed the OEM TVs. Latter I tested with and without and saw a nice gain with TVs. A member tested a 2nd set to TVs in the first 90 deg bend and saw a gain. I copied and confirmed his tests.
I plan to experiment with TVs in the TIP in the next week or so on the Cx 5. The air path to the turbo inlet is a way less than efficient. UGH
We also ran road tests with CAIs vs stock airbox/filter. We found no gains in a CAI at partial throttle or where we operate 99% of the time. Further the stock air filter filters air much better than CAI filters. I could write a chapter on air filters but will reframe. We found the aftermarket TIPs were LESS efficient than stock at partial throttle too. CAIs and aftermarket TIPs market showing gains at WOT. I don't race or plant to race our CX 5. Partial throttle test data is meaningful to me.
These 3rd Gen Rams mostly are high mileage trucks. Mine has 265K on the clock. We spend the money and time to have tight suspension like ball joints and shocks so the trucks track. Tire choice is important. We maintain stuff like belt idler and tensioner parts before as soon as we detect them. Lastly, we run fuel additives to keep our fuel injectors clean.
Most of these items apply to our Cx 5s.
