Doublecabs come standard with a V6, so it's a moot point.

 

You can get a double cab with a 4 cylinder. They aren't popular but that do exist.

 

Well that's news to me. When we were shopping, they were not available. And I don't recall hearing that ever changed, but it wouldn't be the first thing I missed.

Frankly, with the extra weight of a doublecab, I'd think the 4-cylinder would be working too hard -- which can hurt fuel mileage. But to each his own.

There are several mileage threads. Shouldn't be too hard to find some info, just take most of it with a grain of salt. An awful lot of factors affect mileage, and not everyone actually keeps accurate records.

 

Just remembered something that may be relevant. We only considered a 4x4, and it came only with a V6. Maybe a 2WD doublecab can be had with a 4-cyl -- I don't know, as we never looked at a 2WD.

 

According to 2014 Tacoma brochure, 2.7L I4 is standard on Double Cab 4x2 and Prerunner. 4.0L V6 is standard on Double Cab 4x4. Manual transmission is not available on 4-cyl Double Cab.

4-cyl Auto MPG is 19/25 for all 2WD, even my Regular Cab
6-cyl 2WD Auto MPG is 17/21
6-cyl 4x4 Auto MPG is 16/20

4-cyl rear axle is 3.58, 6-cyl is 3.73
Double Cab weighs about 400lbs more than Regular Cab.

Driving style has a larger affect on MPG than any configuration.

My "around town" MPG is about 22-23, still less than 2K miles on odo, but 0W-30 full synthetic oil now factory standard.

MPG is the same as my '06 was, highway mileage, sometimes hit 28mpg.
Figure on 6-cyl MPG to be about 10% less than 4-cyl. 50% more power for a 10% reduction in MPG says get the 6-cyl.

They need to get the Tacoma around 25/30 MPG ratings.
Look at the F150 MPG (17/23), higher than Tacoma. 302HP on their base V6.
If the 2015's get direction injection, this could happen.
However, some body configurations are expected to be eliminated, i.e. Std. Cab.

 

I filled up last night, and I got 19 mpg. I was astounded - my best so far had been 17.6, and that was almost all highway driving, while my 19 was almost all city driving. I'm getting close to 17,000 miles, so maybe it's finally loosening up.

Remember that above 75mph, your gas mileage drops like a rock.

If you can keep your foot out of it in the highway, you can get up there. My V6 4x4 got 21.9, on a leisurely drive south on 101 from SF toward LA.

Using the scangauge cruising around 75, I saw it drop 3mpg above 75, and gained 3 back below 72

Got 25mpg on the last half tank. Mostly rural driving & some in town, no speeds above 60mph.

 

Very little stop and go mostly suburban, 19.5 -20 mpg
Last trip avg 75 MPH = 21 mpg

2014 V6 Double Cab...

 

I remember Toyota came out with a double cab 4 cyl. a couple years ago that was a 5 lugger. I have never seen one in real life so they weren't real popular, but I think that was the only model you could get in double cab 4 cyl. combination. It looked a little weird but so does my access cab.

 

When I bought my truck and I was looking at different millages I also factored in what I was going to use the truck for. If I wanted to haul trailers, move dirt or use my truck to its capabilities did it matter if I lost a little millage. If you just want something for the occasional light house work than I think it makes more sense to buy a more fuel efficient vehicle and than either get a light duty trailer or buy one of those mini trucks everyone is importing now.

 

I hit another new high this weekend - I filled up on Saturday, and got 19.6 mpg. So, it's 19, then 18.6, then 19.6. Hopefully a new and permanent trend. Beats the crap out of 15.5 to 17 (what I was getting for the longest time). Up to approx. 17,400 miles on the odometer.

 

2005 Double cab v6 4x4 mpgs

I've had my Tacoma over 5 years now. It's got almost 200k on the odo now. I have a scangauge and also hand calculate mileage on every tank. In the summer when it's warm I can still get over 21mpg highway. Around town, if I baby it, I can get 18. My best tank was over 22.7mpg. I run the stock 245-75-16 tire size...no other mods.

 

Another new high - I filled up last night, and got 19.8 mpg (339.6 miles, 17.11 gallons), and 95% city driving. Awesome!

 

'09 PreRunner AC, 4 with 5 speed manual. 265-70x17s, speedo reads within 1/2 mph. )vs. 2 to 4 off with stock tires). Work is 11 miles one way, mostly freeway, but a couple miles streets. I usually get 19.8 or so.

Highway trips, maybe 23.5.

Might want to compare your odometer accuracy to mile markers/GPS - if you got your speedometer correct, but your odometer is probably off more than it was before tire change.

Also, as tires wear, odometer error increases, and it gets reflected in miles per gallon being higher.

 

Well, I just finished a trip involving almost all high way driving. After following this thread I decided to slow it down just a bit from my usual 75+. I set the cruise control on 71 per the GPS, trucks speedo was indicating about 73/74. Heading north on Hwy 99 here in CA's central valley(meaning against the wind) and after 215 miles I got 19.5 mpg. Outside air temps were 111* indicated, meaning the A/C ran the whole time. Traffic was very heavy, with lots of slowing to 55 - 60.
That is the best I have ever done going north.
The return trip should be better, since any wind would be behind me. But, it was cooler, late at night, and speed was much more consistant. 65 zone most of the way, cruise set on 68 per the GPS. In the 70 zone, speed set on 71. I will gas up later today to see how I did.

 

You're right. :thumbsup:

You're right. :thumbsup:

I probably could have worded it better originally - just glad we agree. :thumbsup:

 

I have a 2008 X-Runner, and I drive it fairly easy. I get about 18mpg around town, ~23 on interstates rolling 70mph, and ~25 mpg rolling 55-60mph.
