Yeah I really wonder how much longer the Raptor will stay ICE. I mean if you want to go a certain way with propulsion and get people interested and accepting its durability you dont do that with a blob mini crossover. You show the smooth underside of the electric truck flying through the air. Right?

My preference on engines, 7.3 or 5.0, 3.5 powerboost, 3.0powerboost, 2.7 powerboost, 3.5 ecoboost, 3.0 ecoboost, 2.7 ecoboost, 2.3 hybrid, 2.3 ecoboost.

With the powerboost I would probably get it just because of the improved generator output.
Im already fantasizing about that generator. Im thinking hot tub trailer for camping on the mountain. It gets cold up there.

Side note, who wants to be the first one to make a redneck tarp hot tub in their f150 bed and electrocute themselves in style?

Rivian posted this AWD launch and I've seen it probably 50 times now. It's just awesome.

If you make the payments I’ll gladly drive that truck and experiment!

updated chart. Hard to read a little. But dark is Hp. Light is torque.
Sorry for getting off track, but these curves have errors. Torque is a direct function hp and rpm.

Just looking at the curves, it is easy to see issues at 2000 rpm. If the Diesel has the highest torque at 2000 rpm, it should have the highest hp at 2000 rpm. If the 5.0, 2.7 and PHEV have essentially the same torque at 2000 rpm, they should all have the same hp at 2000 rpm.

What's correct?

HP = (Torque X RPM)/ 5252
So as you up RPM, HP increases.

that’s the main reason why.

As for 2.7 and 5.0 it’s very close. And these were taken from a dyno. So I’m sure there is definitely a little wiggle room for errors.

So the 2.7 and 5.0 hp/tq curves are reasonably good data. Then the PHEV and Diesel curves are considerably off.

As you know, HP = (Torque X RPM)/ 5252

Example points:

Diesel at 2000 rpm, if 440 ft-lb per curve, hp=440*2000/5252=168 hp. Curve says 100 hp.
PHEV at 3000 rpm, if 500 ft-lb per curve, hp=500*3000/5252=286 hp, Curve says 200 hp.
PHEV at 2000 rpm, if 315 ft-lb per curve, hp=315*2000/5252=120 hp, Curve interpolates ~70 hp.

This is more than a little "wiggle room".

PHEV is 100% guesstimating. Combining a Chevy Bolt with the 2.3

but the diesel I took from fords website

Fair enough. Then I would suggest to note the guesstimated torque for the PHEV and back out the hp using the formula. This at least keeps the hp/tq consitent.

As for Ford's curve on the website, it appears to be a marketing cartoon. There are dynos available for accurate info, if needed.

Just a note, whenever you plot hp and ft-lb torque on the same numerical Y-axis, you should see that the hp/tq curves intersect at ~5250 rpm. Again, back to the hp/tq formula. This is a good "stink" test for dyno data.
