Rho mpg

[MT755]

I looked on fueleconomy.gov and they change the rho's mpg ratings
City 14
Hyway 16
Combined 15
It was the same as the regular ho before

Honestly the combined mileage is maybe 1 mpg less than we get with our Hemi powered 2020 Limited. But for anyone that's concerned with fuel economy there are lots of better choices than an RHO. I don't see anyone buying them for fuel economy.

37% more horsepower for a 1 mpg hit - seems like a decent trade off to me.

If you're buying a RHO, you're not concerned with fuel economy...

Funny thing is, if you want pure power (and don’t give a hoot about mpg), then you’re not buying a RHO.
But with that said, here are the calculations on the never-before-heard-of horsepower to mpg ratio:

5.7L Hemi (assuming 16 mpg):
395/16 = 24.68 Hp/mpg

3.0 Hurricane HO (using 15 mpg):
540/15 = 36 hp/mpg

6.2L SRT (TRX, using 12 mpg):
702/12 = 58.5 hp/mpg

I therefore conclude that the TRX is the most efficient engine out there lol

It's just an observation. I could care less about my TRX's mpg.

The best part about the analysis is that the numbers get better as the mileage gets worse.

I get more like 10 mpg in my TRX.
702/10 = 70.2 Hp/mpg
That’s even more efficient!
