Thanks for ruining my day Chris. I thought my Forester was doing good to average 37.7 mpg over the last several K miles. But the Forester is bigger and with a 2.5 l instead of your 1.8 l. My wife’s CRV averages around 34 mpg. But we all know that the drivers have a lot to do with fuel mileage.
Amen! I can get better mileage by controlling the gas pedal as well. Cruise control has only one prime objective, maintain NN MPH above all else. You will notice when traveling up even the slightest incline the trans will change ratios and engine rpms will increase to maintain NN. When I control the throttle and I approach an incline, I don't mind the speed dropping a few mph when I keep the throttle plate in the same position. Also, when travelling in hilly country, I will let let the vehicle gain a few mph on the downhill slope which offsets the mph you lose on the incline. I pretend I have an egg under the accelerator and apply only gentle pressure.
Cross trek is normally aspirated 2.5. accelerates briskley. To over 110. Maybe impreza has a 1.8. your average is fine. Milage dropped a tad now that I am at altitude and dry air but I am happy. I would question your belief about gas peddle. Even though I have 7 "gears" at any given speed, there is a small bit of hunting due to small hills. A Ford engineer at Oshkosh told me engineers HAtE sticks. Worse emissions and fuel economy. I don't use the radio but I sure love the glass cockpit and upgraded lane holder. One button for nav and I can talk to nav lady and she says, BUTTE MT. Let's Go! Another button and I see .my car on My Radar. Another and the car sticks like glue to the center of the lane for 15 seconds before telling you to rest your hand on the wheel. Great for finding that lit cherry bomb you dropped between your legs. I guess I use the volume knob for phone calls? When Bitchin betty tells me there is a cop ahead or road debris I can't turn down her voice. One bizarre thing. I filled up today and couldn't hear the engine was still on. So I looked at the tac and sure enough....
Mobile gas economy run said the same thing! When I ride, I make a game of trying to not touch the throttle lock. IF and only if one is allowed to let the speed vary, it would be interesting to see if it's man or computer who wins. When the computer was getting 40+ it was gently rolling Wisconsin. An SAE paper is in order. IF the computer were allowed a variance I still would not bet against it. If man were not allowed a variance, I would bet against him. In flying, we have a prop/engine rpm, a manifold pressure gage and an EGT gage. In a car, the computer controls many things and I just tell it the speed and how fast I want to get to that speed.
No tail wind. Slight side wind
Hummm. I guess things changed. My son’s wife has a Crosstrek with a 1.8. My Forester is a 2.5. Both are naturally aspirated.
The 2025 base model, which no one buys due to lack of some safety features, is a 2.0. Dont know the rear end gear ratio but dont get the Wilderness. Designed for towing...low rear gear...
