Throttle response: 2014 vs. 2023

[thatoneguy]

We have a 2014 with 340K miles on it. It regularly goes back and forth between Southern California and Montana. It has never posted more than 19+ mpg on the highway. Experience says best mpg is between 60 and 70 mph. Go above 80 mph and the mpg drop into the 18 range.

We have a new 2023 ORP and it’s posting the same mpg figures. There is no difference in performance between the two.

This, of course, makes complete sense. The 2010 4Runner has a 4.0L V6, 5-speed automatic, and 31.6" tires. The 2023 4Runner has the same. No performance difference, no real-world MPG difference between the two.

The EPA ratings dropped through the years because the EPA test methodology itself got tougher. Chances are, the 2023 4Runner's test was subject to much harder acceleration, more changes in speed, and more idling time than the 2010 was at the time of 2010 testing.

I've gotten 25mpg on my 2023 on multiple 200+ mile runs; probably because I find it really relaxing to cruise 65mph on two-lane rural highways, and I really let speed bleed on steep uphills rather than holding 65mph at 3500RPM. :biggrin1:

Not helpful, different color might have made a difference.

Old dying cats. My 2010 cats went bad at 100 thousand. You can definitely tell that the power is decreasing and gas mileage going down. Assuming you've maintained the truck.

This is a known fact. The EPA changed calculation method for MY2017+.

2017 Ratings Changes

Most vehicles saw a drop of 1-2 MPG due to the change.

Blah, blah, blah. You sound like Joe Isuzu claiming 25 mph going downhill in the slipstream of a big rig.

No change:

Er, did you get served divorce papers? 401k doing poorly? Favorite fast food sandwich get discontinued? What else could cause someone to be this cranky and abrasive without reason?

You've been told you're wrong on this subject by like three different people on this page. Whatever, case closed, have yourself a phenomenal day, keep that bootyhole clear of any swinging doorknobs.

Just in case there was any confusion, I'll restate: The 2023 4Runner is rated lower on EPA MPG than the 2010 4Runner is. This is an objective fact, links available on demand. Since virtually zero hardware changes happened, this is probably because EPA tests got stricter, with more idling, harder acceleration, more changes of speed, et cetera.

Thank You for pointing this out. Cutthroatslam is a "know it all". I think that he is jealous because Jeremy has more miles on his 4R than slam does.

I don't even know how many miles Jeremy has.
