Numbers very possible depending on HOW you drive. To get my numbers you have to limit acceleration to 2 bars, wait for the car to get to speed on the highway might mean like 1 minute if you're climbing at the same time, brake efficiently 100% brake score every time, unless some other reason causes it to not be 100%, someone stepped out in the road or the light turned yellow at the last minute.
I'm attaching a file today from my drive. I went from Franklin where I live, to Norfolk, to Walpole, to Patriot place in Foxboro, to Wrentham Premium Outlets in Wrentham, and back to Franklin. Its a 31.7 mile drive burning 5.5 kwh of battery, with some little ups and downs in the road not talking major steep hills but normal inclines. I did recharge it at Patriot's place back up to 65% but MFM did not log that event. In any case, this driving was up to 45mph max speed in EV mode, I would say high 30's on average. No cruising at any point was at 25mph, that's just waaay too slow. generally speaking I'm at least 35mph when I drive most of the time between that and 40.
At the rate I was going its about 32 miles per charge, you can calculate each trip individually or add them all up and confirm for yourself.
On the engine I can net high 50's I've seen it as high as 60.7mpg in the summertime driving city streets in Boston in hybrid mode with mass pike or storrow drive or I93 speeds of around 55 mph on average, max speed say 62mph. This car does really well when you slow down a bit. If you punch it to 75mph you're going to cut your mpg numbers from high 50's to low 40's maybe even high 30's depending on if the terrain in flat of hilly like Vermont. That makes a difference also.
Levi suffers severely from low mpg numbers and EV range due to the fact that he lives in hilly areas. His case is not the usual case, but the extreme duty case. Plus he drives on dirt roads which worsen the range and mpg rating as its harder to roll on those. Those cause him grief because the backup camera gets covered in mud and/or dust.
Also below I've attached the RAFE (running average fuel economy) of the ICE only in hybrid mode which translates to the gas range when you fill up the car. First picture was taken June 15th, at 58.6 when you fill the tank the multiplier is 14 gallons so the range would be 820 miles in this case. This number goes up and down depending on if you drive faster or slower in hybrid mode (not affected while driving 100% EV in EV now or Auto with a charged HV battery). Let me go down to the car now and power it up and take a picture of the current RAFE...
OK, a picture or several pictures are a 1000 words. Let me explain what you see below:
First picture is the RAFE as of today, 6/26 of 59.9 mpg. Filling the tank means a predicted range of 838 miles. Note that I drive with alot of thought content about what power to use when (EV or ICE) and how much power (try to not go over 65 amps on the battery and 2000 rpms on the ice) and I plan ahead alot so I never waste brake pads unless out of my control.
2nd picture is showing you the amount of fuel remaining in the tank. Looks like a little over 1/4 tank to the right, but the actual number is 386. A full tank is 1004. So 386/1004 x 14 tells the amount of gas left in the tank. In this case 5.38 gallons.
Range on gas is showing 282 miles, on the battery 7 miles. 282 miles / 5.38 gallons = 52.41 mpg. Not in line with RAFE but RAFE is an average that goes up and down, on the last drive I used more gas than normal and my range dropped faster than the miles I drove and RAFE should be averaging down. In fact it did, I did see it a couple of days ago at an all time high for me of 60.7. Like I said depends on how you drive, the last day I went to Boston then to Malden then back to Milton and back to Franklin. It was more % high driving and less city roads.
The battery is showing 7 miles range on 20% HVB remaining. This would equal to about 35 miles per charge. Last picture shows predicted range on next charge to 34 miles. Note my driving style is full green, better today than the highway roads I took last trip, I didn't use climate, last time it was raining and I HAD to use the AC as the windows were constantly fogging from rain / 100% humidity otherwise, and the outside temp today is slightly warmer (70's) than the 60's it was while raining the other day.
As you can see, its possible to get much better numbers. Note the blue coach bars in one of the pictures below, all full blue. What you want to aim for especially in EV only mode. When running the ICE one the highway long distance I bring the cruising bar to 1/2 just barely blue (less than half its yellow) at a cruise speed of 66mph.
And please go and search here you will see many posts about my long distance trips to VA, FL, Indiana, etc, with at least 48mpg at a constant cruise control speed of 66mph.
There is alot of proof of what can be done, but it really does depend on you and your driving.
