You are correct that dyno charts don't show turbo lag. But if you're at 2k or above in the 2.7 (my only reference) it's very, very minimal. And then once you have boost it's much more powerful than a coyote from like 2k to 4k ish.
Not saying either engine is better than the other...
I was prepared to "well acksually" you but yeah looking at that chart it is so flat before 5.5 and falls off so hard after, you're better off just shifting at like 5.5k
I'm not sure I see the value in a dipstick. If you're going to crawl under there and mess with it you could just drain and refill in the same time for a few bucks.
That hybrid design doesn't work well with rock crawling, unfortunately. At least in the way it's been implemented in other vehicles.
I'm sure there is a way to get around that, maybe pairing it with an automated two speed transmission or a crazy deep transfer case, idk.
The Prius has been possibly the #1 most reliable car since it's launched.
Also consider your accessories are all electric (and more yes, more reliable)
No belts to change
Your brakes last forever because they're barely used.
No starter to go bad.
Etc etc.
Comparing the f150 powerboost to the 2.7 is apples and oranges. The f150 is set up for capability, not efficiency. It can do things the gas f150 can not do.
430hp and 570ftlb, it should be compared to the mileage of the 5.0 or the 3.5 HO.
Hybrid vehicles currently are the most reliable and lowest cost to own cars. The Prius in general is insanely reliable. I took a cmax to 220k miles and there was not a single issue with the powertrain and in fact you save on things like belts, brakes, and other accessories.
