That's about what I expected. 1 mpg better than my 2023 Pilot TrailSport haha I'll take it!

 

[Boobajoob]

Not what I envisioned for a hybrid years ago, but I'll take the power for towing.

I wonder how the hybrid will handle in our Canadian winters here in the Rockies. We're good for a week of -40 every year while at 3500ft in the city.

 

[et2041]

I'll gladly take that on a TRD Pro. My 2012 Trail edition with M/S tires averages ~17 mpg city and ~ 19 mpg Hwy.

Nice improvement compared to the 2024 4Runner 5th gen

• 2024 Toyota 4Runner SR5: Up to 16 mpg city/19 mpg highway*
• 2024 Toyota 4Runner TRD Sport: Up to 16 mpg city/19 mpg highway*
• 2024 Toyota 4Runner SR5 Premium: Up to 16 mpg city/19 mpg highway*
• 2024 Toyota 4Runner TRD Off-Road: Up to 16 mpg city/19 mpg highway*
• 2024 Toyota 4Runner TRD Off-Road Premium: Up to 16 mpg city/19 mpg highway*
• 2024 Toyota 4Runner Limited: Up to 16 mpg city/19 mpg highway*
• 2024 Toyota 4Runner TRD Pro: Up to 16 mpg city/19 mpg highway*

Really solid, IMO. It will be nice to not have to drive like there's an egg under the accelerator to just get 18mpg highway like my 5th gen Pro.

Personally, I'm disappointed with the expected MPG compared to my 4Runner V6 and "old fashioned" simple transmission. Why 4WD rather than AWD, for non-off road versions, it adds complexity to the diff and probably weight.

It’s over 30% increase over the V6 on the highway and nearly 20% increase in the city. That’s massive.

AWD adds drag, weight, and cost which hurts gas mileage. Part time 4WD is why the Sport gets better highway gas mileage than the Full Time 4WD Limited.

 

[BG1]

OK, I misread the spec for the TRD Sport, its 2WD and part time 4WD that makes more sense. Limited and above get the fulltime 4WD. The sticker of our TRD Sport V6 with a 5 speed is 16 city and 19 highway. We get 19 locally where it's very hilly and 24+ on the highway.

Sorry, but I don't see 19/25 as a massive improvement, in fact my money says the turbo will need to be pushed harder locally. I'll take any improvement, but I suspect we will miss the V6

I expected more of a difference between gas and hybrid. Is the tank smaller in a hybrid? What is the weight gain for the battery. Not sure its worth the $3K for the hybrid

A few reasons --

The gas engine models are the only one available with 2-wheel drive, which is more fuel efficient than 4WD.

Also, the i-Force Max Hybrid is reserved the upper trims (TRD Pro, Trailhunter), which have a lot of off-road features (4WD, extra ground clearance, bigger/knobbier tires, etc.)

Toyota's approach with the hybrid tuning in the new Tacoma and now the 4Runner was to focus more on power delivery than efficiency.

To build on this, the hybrid is not meant to a be a fuel sipper option versus the standard model. It is the performance powertrain... which we didn't have on the 5th gen. Toyota had 2 basic choices when making a higher performance 4Runner option. The V6TT would be one and adding an electric motor and battery to the turbo 4 would be the other. If Toyota had done the V6TT in the 4Runner, that hypothetical vehicle would have maybe done 1mpg better than in the GX due to saved weight and would have been a similar cost up as the hybrid. We will compare the Limited trim because that is the only 4Runner that has FT4WD like the GX to give apples to apples MPG comparison.

Model	Trim	Engine	Power / TQ	4WD	City MPG	Combined MPG	Highway MPG
4Runner	Limited	2.4T	278 / 317	Full Time	20	21	24
4Runner	Limited	2.4T HEV	326 / 465	Full Time	23	23	24
Lexus	GX 550	3.4TT	349 / 479	Full Time	15	17	21
4Runner	Limited	3.4TT	349 / 479	Full Time	16	18	22

IMO, Toyota made the right choice. The V6TT is kinda close on the highway, but local driving is a massive difference. And, TBH, the hybrid is probably a lot more pleasant to drive around the city and suburban driving because the electric motors provide instant torque.

 

[kekecarioca]

It's a massive improvement considering weight, tires, poor aero.... I was really hoping for high 20's, but that was clearly a dream I was aware of. Also the LC 250 already kinda burst that bubble sooner.
I've been trying to find some results online on "granny diving" in the city and hiper mileage on the Taco I-force max. but no luck yet.
I suspect you could milk the mileage pretty well on low speeds considering the EV propulsion... Feel free on your 2cents.

When we put our 4Runner in 4WD, unless the road is wet or snowy the wheels shudder since they don't want to turn at the same speed when steering left or right. Thats normal.
So does the fulltime 4WD version have a different differential set up, I guess it does.

Yea, with FT 4WD -- like the Limited and Land Cruiser have -- the vehicle can be in 4WD on all surfaces without risking damage to the transfer case. This is because there is a differential between the front and rear prop shafts allowing them to turn at different speeds. Part time 4WD systems don't have that center differential.
