The onboard MPG calculation during the run through the Colorado mountains with a loaded down car.

Image


It maxed out at 199 mpg and stayed there for quite a bit of time, but I didn't get a shot of it. At least we now know what it maxes out at.
 
Mount Umunhum ("Resting Place of the Hummingbird" in the Ohlone language) is 4th highest peak in the Santa Cruz Mountains, near San Jose, CA. The 2-lane road goes from 3,486-foot elevation at the summit down to sea level in only ~3.8 miles of steep, twisting curves.

There's an 84 foot tall radar tower at the top built in 1962 during the Cold War to watch for incoming boogie-people. The area is now open to the general public and the Ohlone are allowed to plant gardens and hold religious ceremonies up there.

EDIT: That works out to about a 17.4% downhill road grade.
 
Yesterday I was looking at Tesla Model 3 Extended Range models and comparing the "savings" with the Accord. My 2014 has averaged 30 mpg over it's first 200k miles (i do 10k mi trips and the mileage over that distance only varies based on season, with winter and remote start idling bringing it down to 29 and spring/fall being 31). Tesla has a calculator to determine how much money you save on fuel. For the first 6 years of ownership, It says i'd save $12k in fuel assuming 20k miles a year, 30mpg, and current gas prices. Given that it's a $65k car, i'm not sure you ever even break even when buying a <$30k Accord since you'll be replacing batteries in the Tesla before that point. I also don't expect that you'd offset the carbon footprint of an EV with something as simple and efficient as a US made Accord. Of course, there's also the benefit of having a new Tesla that really is the car of the future. FWIW, I have a 2023 Camaro 1SS V8 on order... so not buying a Tesla.

Even 200k miles in, I will still consistently average 40mpg when driving 55mph and I average 34mpg when driving 70mph. I think that's pretty impressive for a NA 2.4L non-hybrid. This car has been an awesome value and I still enjoy driving it.

@keep_hope_alive Since you mentioned the lifetime average, here's some detailed stats that I've been keeping on mine from very first tank filled (bought the car new). Had been noticing the mpg's dip a bit of late, but having done the CRC intake valve cleaning recently, this has restored mpg's quite a bit. Should average a little over 32 mpg by 200k.

That's great information. Excellent job keeping track.

Make sure you look into the cost of insurance on that Tesla. They average about triple of your accord. There goes your fuel savings $$$[emoji3446]

Our Accord does well. But, our 2018 Dynamic Force 2.5L Camry beats my 2014 LE Accord handily. Camry has 200+ HP from a NA 4 cylinder engine, averaging over 40 mpg even with my "not driving for economy" wife operating it. Just drove to Chicago and back, almost 800 miles each way. Got just over 40 mpg with three adults and a week's worth of luggage plus photography equipment packed in it. Averaged 74 mph on the return trip, including 3 stints of stopped traffic. I was going nearly 90 mph at times. I can get just over 40 mpg on the Accord when I'm by myself and paying close attention at slightly higher-than-posted interstate speeds...I'll be at the fastest speeds at the bottom of hills, and the slowest at the top of hills. I get better mpg this way than when using the cruise control. With the Camry, not paying close attention to fuel efficiency, even with three adults, I'll get a bit more than 50 mpg when about 25% of the roads are highways with 60-65 mph speed limits and the remainder is Interstate with speed limit of 70.

Best way to get the best MPG's in bold.... (y)

Agreed. Those that get better MPG's by using cruise control are not attentive drivers. I beat cruise control numbers by several percentage points on any car I've had that offered cruise control. My wife complains I drive too fast, yet, I ALWAYS get better MPG than her by anticipating braking and acceleration as well as when to let-er-roll down the hill...and I don't have to be as fast as the speed limit at the top of the hill. I don't get in the way of traffic flow, but, on a 70 mph interstate at the top of a hill, I may only be going 65...I'll perhaps be close to 80 at the bottom of that same hill on the other side. Let inertia help you when it will, and don't fight it when it's against you. Love the practical physics.

Accord (cvt) isn't really the best for mountain driving. You can't force it to hold a lower gear going down. Sure there's the "sport" mode but that's probably not enough.
Disagree ... Mine is a CVT and just came off of some high altitude mountain runs earlier this month. Put the shifter down from D and the transmission logic does a fine job. Don't CVTs technically have an infinite ratio in terms of gearing? So optimized in this regard I'd think...
