Got that!
I was only referring to the fact that the Trail, is NOT AVAILABLE with full time 4WD. As far as the MPG ratings, I'm completely naive.

2013 4Runner EPA mpg rating lower than 2010-2012 4Runner?

The 22 hwy for the 2013 SR5 and LE is for the 2WD model. The 2012 2WD SR5 and LE were rated 23 hwy.
The mileage figures for the 2WD and 4WD models are listed at the bottom of page 17 in the 4Runner brochures.

I looked at your data specs; 2012 & 2013. And the only difference between the two model yr vehicals, is the mpg publication; the S.U.V's mechanical design has not changed at all (according to the two "Owner's Manuals", 12 & 13).
The other thing that I was looking at was, how they never tested the T.E. in 2WD mode, as they did the others; perhaps just to produce a more realistic result, with that particular 4Runner being 'more or less' designed for "off-road" venturing.
As far as the mysterious "1 mile per gal loss, well....it could be anything: fuel quality, human error, even "Lazar malfunction" (distance calibrations),etc...
The main thing is (imho), that the 2013 4Runners, have not changed from the, now trusted 2012 models, so... "Buy With Confidence"!!

I think you are misinterpreting the brochure. If you look at the "Specifications" page, you will see that the SR5 and LE come standard with REAR WHEEL drive. Models equiped this way are designated "4X2" which accounts for the higher MPG. Four wheel drive (4X4) is indicated in the brochure as "Available" for the SR5 and LE, and Standard for the TE, which is why they all have the same "17/21/18" rating.
The difference is between rear wheel drive models and four wheel drive models, not that they "...never tested the T.E. in 2 WD mode..."

Hi STLDAVE,
I agree with MOST of what you are explaining, No problem!
But in the brochure, spec page, Look down where it say's, "Drivetrain", just below "Transmission". The rear wheel drive, with "Automatic Limited Slip Differential", is Not Available NA, with the Trail. But, "Part time 4WD with active traction control" (A Trac) is standard equipment on the Trail model.
It never say's that the Trail only comes with 4WD. it say's, part time 4WD is standard. Part time....which means that it has a 2WD mode as well.
Now, if you look down at the bottom of the page, "Mileage Estimates". And you look over underneath the Trail column, on the 4x2 line, under "Trail", it say's NA, for, not applicable, or 2x4 testing was not implimented during this test procedure.
Under 4x4, it published 17(street)/21(Hwy)/18(avg). We know that they could have tested the Trail model in 2x4 mode, because it doesn't have "Full Time 4WD". They just opted not to test the TE in 2WD. Hope we're on the same pg now!

Rigtec maybe I can help convey what the others are trying to say. Go try to buy a 2wd Trail Edition 4Runner.

With that said, the parasitic drag of 4x4 is there whether or not 4wd is engaged. That's why the 1mpg difference, almost all 4x4 vehicles I've ever seen receive roughly 1mpg lower EPA than their 2wd counterpart.

Ok listen,
I get that you cannot buy the "Trail model" with only 2WD, I get that. It's clearly not offered (I'm not addressing that again).
But our brochure, mpg section clearly reports a different set of numbers, between vehicals while driven in 2WD vs the same vehicals, when driven in 4WD. These trucks can NEVER consume the exact same amount of fuel in either mode.
They always use more fuel, after being swicthed into 4WD; that's why the chart shows results in both modes, and every year.

I don't know what brochure you're reading but you're reading it incorrectly. The 2wd EPA estimates are for 2wd only models, the 4wd estimates are for 4wd models. Your 4Runner's hubs are locked the front axle is always turning, that's constant parasitic drag. If you had manual locking hubs and left them unlocked and transfer case in 2wd then you wouldn't have that drag, that is where the 1mpg EPA estimated fuel economy comes from.
It's not two different estimates for a vehicle driven in 2wd and then driven again in 4wd.

If what you are saying was correct, there would be THREE rating for the SR5. One for the rear wheel drive version, one for the four wheel drive version in rear wheel drive mode, and one for the four wheel drive version in four wheel drive mode.
The reality is, the EPA tests are conducted in on road testing as the vehicle is typically driven. They tested the rear wheel drive version to get the results for that model only (4X2), then test the four wheel drive versions in the mode they would be driven on the street, not off road. For the 4X4 versions of the SR5 and the Trail Editions that would be in the rear wheel drive mode. There's no difference in the LE ratings with its full time FWD and the other two because of other factors such as the lower rolling resistance of the narrower 20" tires.

true gas milage??
I am in the process of buying a new 4runner. Either a 2012 leftover or 2013. Probbly a Trail edition, and I plan on installing a lift and slightly bigger tire.
You guys that are running lifted 4runners, what kind of gas milage are you seeing?
Thanks in advance for the help.

Wow -- don't know what you are doing, but my 2012 LE is averaging about 18 and I'd bet 80 percent of it is highway driving. If I granny drive at 60 mph, I might get 20-21. Never touched 22 average.
That's with pretty much just me commuting to work.
Anybody else experience similar? How on earth does one get 22+ mpg in this thing?

Few things I can see making it possible:
-his truck is 2WD
-he drives on a lot of suburban roads 40-55MPH
-he has a very long commute, cancelling the warm-up fuel economy lost
-he lives in a low traffic and flat area.
-...
I think 22 is doable if you stay under 65mph highway driving if you are kinda lucky with traffic, but you ain't gonna wait 10 minutes for your hamburger at mcdonald drive-through while your engine is running.

I noticed today on a 4 hour trip between I-65 and I-20, my 2012 Limited was getting between 18-19 on the highway. I was going 73-80 mph average. What happened to the 22 mpg advertised on the highway? 
I guess they meant a highway no more than 55mph.

You have 31% more aerodynamic drag at 80mph than 70mph. Aero drag makes up something like 75% of your total system drag (rolling resistance and drivetrain drag are much lower at this point) at those sorts of speeds. The EPA test really doesn't hit those speeds other than a supplemental test that is just there to help make the numbers a little more real world. The drag difference between 55mph and 80mph is a whopping 112%! My best advice to save gas is to slow down and use your brakes less. The less you use your brakes, the less energy you are converting to heat in your brake pads and rotors.
I have averaged 22.12mpg over 29800.0 miles (1346.93 gallons; $4,544.90) in my 2010 4Runner since July 10, 2010. Max = 24.99mpg, Min = 19.64mpg.
I drive 95% interstate (65mph, 70mph) and highway (55mph). The highway driving is my short, 6 mile commute where the vehicle doesn't warm up until I'm pulling into the parking lot at work. Few stops, but I see a decent drop during the winter when the vehicle is mostly driving in a rich condition. I do NOT let the vehicle idle before leaving for work, I don't go through drive-thrus, etc.
My Prius wagon/van has averaged 41.30mpg (max 43.20, min 39.74) in pretty much the same driving conditions other than a lot of idling in school traffic and baby-in-the-parking-lot-with-wife-while-i-run-into-the-store.

I am chalking it up the difference in mileage between the Trail and others to 0.6" extra ground clearance, and a bigger roof rack. I just removed my RR to see what my Trail would look like and I can not believe how much quieter it is on the highway! That wind buffeting with the RR attached has to account to something.

As pointed out above, I neglected to notice that the TE only comes in 4WD while the SR5 and Limited have 2WD models. The 22 is for the 2WD models. They were previously rated at 23. Ground clearance is listed at 9.6" for the SR5, TE, and Limited (all 4WD). All 2WD models are listed at 9.0".
