How's everyone's hybrid MPG stats looking lately?

Still hanging in at 14.9 combined on the Trailhunter.

1100 miles and so far mixed sensible driving and it hasn’t climbed above 17.0. Curious how some of you are in the 20’s by the 2nd fill up.

Do you drive over 70MPH a lot, I noticed my MPG's really drop once I get up there in speed in both Hybrids.

 

[SouthCoast]

TRD Pro. 2k miles. Eco mode driving. Live on a mountain. Home to work downhill 21 MPG. Work to home uphill 14 MPG.

Average 17 MPG.

Lightweight Volk wheels 19 lbs each vs 29 lbs stock. Reduced 40 lbs rotational weight. Stock 265 tires. No heavy offroad mods.

How are you getting 21mpg going downhill? I get 26+ on the flats...

We're averaging 22.08 over 4962 miles. I can manage 26+mpg on the highway anywhere between 70-75mph. How are you not?

No clue. It’s about 14 miles to and from work. 3 miles of which is mountain. 11 miles is flat. The trip odometer says 14 mpg home. 21 mpg to work. Eco mode.

I get that our hybrid motor and drivetrain are geared for power and torque. That makes sense in lower gears for offroad. But… I would think they would make it similar to their Highlander or sienna in higher gears to conserve fuel.

I’m now over 19 mpg average and have hit 22 briefly several times. I’m rarely over 70 Hwy and mostly lazy speeds around town. I leave adrenaline driving for the Porsche.

 

[Widnere12]

I’m averaging about 85% city driving and avg just under 19mpg

 

[Wagzilla]

Hi I have TRD Pro 4-cylinder turbo hybrid 1,460 miles and average about 20.3 mostly freeway driving @78 to 83 miles an hour.

Now that I've run several tanks with bigger tires I'm ready to summarize my data.

Bottom line:
Before: TRD ORP: OEM wheels/tires/air dam; normal mode; 80% hgwy (by distance); 39# pressure (except offroad); 93 Octane: 22.3 MPG. (average of 7 Tanks with those conditions)
After: TRD ORP: TRD Pro wheels (18"x8.5"); 285/70R18 Toyo A/T III; no air dam (rubs); normal mode; 80% hgwy; 39# pressure (except off-road); 93 Octane: 18.5 MPG (average of 4 tanks)

This is a substantial difference in range on the 19 gal tank: ~425 vs 350.

A data point: Similar highway trips compared before and after - 3+ MPH better before loss of air dam and bigger (and heavier!) tires. The impact around town (for my 1.8 mile "commute) is MUCH worse. (15-18 MPG vs 12ish MPG).

BEFORE: all highway (stop and go on I95):

AFTER: all highway (stop and go on I95):

And some details (bolded rows are tanks that include substantial time (and 10-20 miles) in 4LO off-road:

This is EXACTLY what I've noticed with our 4Runner still stock and my Tacoma with same wheels as you and 275/70/18's. It's made me rethink the upgrades I was going to do to the 4Runner, I think I'm going to stay with what's on there stock and just level it with better 265's now.

 

[papadop88]

TRD Pro on 295/70/18 Recons (53lbs per tire), Prinsu Pro Rack (all this matters...)

The tires definitely throw off the calculations because of the bigger diameter. I would say in reality I'm probably getting 1-1.5 mpg higher than what the computer or the gas pump tells me.

Lifetime Average (3100 miles so far): 17.0.

Depending how I drive I range between 13-22 mpgs.

I had AI summarize the i-Force Max Hybrid MPG figures reported in this thread so far, broken down by driving style:

Driving Style / Condition	Typical / Common MPG Reports	Notes / Extremes
Moderate / mixed driving (city + highway, moderate speed, ECO mode / gentle driving)	~ 20 to 22.5 mpg	One user: averaging 21 mpg over ~40% highway / 40% backroads / 20% town. (4Runner6G.com)
	~ 22.0 – 22.1 mpg	Report from “MikeLSV” on his second tank: “22.07 … mix of highway @72 mph (70 %), city (most of rest), and 4HI off road (15 NM).” (4Runner6G.com)
	~ 22.9 mpg	Report in ECO / town driving: “I’ve seen … 22.9 while driving around town in ECO mode” (4Runner6G.com)
Primarily highway / cruise / favorable conditions	~ 19 to 20 mpg	One user did CC at 77 mph and got 19.4 mpg (3 passengers + light bags). (4Runner6G.com)
	~ ~20.3 mpg	Round trip average from one user including highway: “21.2 reading … round trip avg was 20.3” mpg (4Runner6G.com)
Mixed, moderate (with hills / backroads)	~ ** ~21 mpg**	“Been averaging 21 mpg … 40 % highway, 40 % 45 mph backroads with long hills, ~20 % town” (4Runner6G.com)
Towing / heavy load	~ 12 to 14 mpg (much lower)	One user towing ~4,000 lb box trailer got ~14 mpg in TOW/HAUL mode. (4Runner6G.com) Another: “in TOW/HAUL … averaging 12-13 mpg” with similar mix of roads. (4Runner6G.com)

Observations & Comparisons vs Non-Hybrid Thread

1. Higher baseline in many cases
   For non-hybrid 4Runners, many values clustered in the high teens to low 20s mpg for mixed driving. The hybrid thread shows that under moderate driving, many owners are achieving ~20–22+ mpg fairly reliably — an improvement, especially under favorable conditions.
2. Greater sensitivity to speed / load / conditions
   Even with hybrid, high speeds (e.g. CC at 77 mph) drag mpg down, and towing or heavy loads dramatically erode efficiency. The delta is large (e.g. 12–14 mpg when towing).
3. Reporting / instrumentation caveats
   • Most of the reported numbers are from the dash / instantaneous / average fuel economy readings (rather than independent tank math).
   • Some comments suggest the vehicle is still in “break-in” period, so early numbers may not reflect eventual steady state. 4Runner6G.com
   • A few users express disappointment at not matching advertised highway MPG (e.g. setting CC at 77 mph, expecting highway rating, but getting ~19.4 mpg). 4Runner6G.com
4. Spread is wide
   The spread in real-world performance is large (from as low as ~12–14 mpg when towing to around ~22.9 mpg in light ECO mode). That level of spread is consistent with how much load, terrain, speed, and driving style matter.

 

[RogueWarrior65]

I had my 5000 mile service done and added an oil change. I could be nuts but it seems like the MPG is better after that.

That said, the EPA in its infinite wisdom does highway mileage testing at 60 MPH. I don't know anyone in the southwest who drives that slowly on the highway.

 

[spyder40]

In notes on each tank is mode and what dash showed. I reset everything on fill up. ORP with air damage still and TRD Pro rims with Michelin LTX Trail tires it came with
