Why does Toyota list the Prerunner 4x2 with the same MPG as the 4x4??

My 4x2 2007 gets better MPG than the 2007 4x4's Why are they listing the 2008's with the same MPG 16-20 C/H.-Rich

 

who knows, when i bought my v6 prerunner, the sticker said 19/22, then last month they switched the prerunners at the same dealership to 16/20, so i have no clue whats going on. the good news is i just averaged 17mpg on my last tank and i think thats the first time i ever got over 15mph, i usually barely hit 300 miles when the needle almost touches the E lol, this time i got 345 miles

 

I get normal average 19-20 around town and 20-22 on the highway. I see that most of the 4 wheelies here get about 1-2 MPG less?

 

how the hell slow do you have to drive to get 19-20mpg in the city?? are you just rolling down hills all day or what?

 

That's average I don't carry anything but I have a shell and I try to stay at under 2K and I keep my tires at 32-33PSI Cold (coldest part of the day fill them) When my wife drives it the average is about 1/2 mpg lower. If I get stuck on the freeway behind a wreck or some other hassle of course it is lower then. I get the same MPG regularly. Somebody said here drive like there is an egg under your foot....LOL

 

2007 and 2008 use differing test methods, and that is why the mileage figures differ.

 

I believe they're using new methods across the board for new cars, trying to get more real life numbers.

 

Why would the 4x2 have the same numbers in 2008 as the 4x4 when in 2007 they were different. Both numbers 4x2 and 4x4 should not be the same, different methods or not. They should be lower then 2007, but in the same ratio...Rich

 

I drive like I just took a Geratol, and I avg 19-20 mpg in a V-6 4x4.

 

i drive it like i dont wanna get pulled over again now haha, already got 2 tickets in 2 weeks

 

---------------------------------------------------------------------

Me, You, and even Toyota have absolutely nothing to do with those numbers, nor how they are derived, The EPA does the test, and doles out the numbers. They are only a guidline.

 

Reason being....the pre runners and the 4x4's both have 4.10 gears in the rear differential. The power drain from the 4x4 is 2wd is pretty non-existent and the only real issue is the extra weight which doesn't affect it much highway mileage at constant speeds although it woudl affect it accelerating.
I have a 2007 4x4 2.7 and I get 25mpg consistently on the highway going 70. I've gotten as good as 26.5mpg before. I usually get around 21-23 in town driving normally shifting at about 2500-3000rpms

 

Well, why wouldn't they list them as the same? I mean, if they really are the 4x4 numbers, and they just put those numbers on the 2wd trucks, everybody wins. The 4x4 drivers think, "hey, I get what they said I'd get and that's the same as the 2wd." The 2wd drivers think, "hey I get better mileage than they said I'd get." It's a win-win...until, that is, somebody points this out...

 

From what I've read here both 4x4 and 4x2 get about the same MPG. I'm averaging 18.5 MPG with 90% city/traffic. Like Mudbug said, it's all in the gearing.

 

Once I get more data collected from this thread... http://www.tacomaworld.com/forum/performance-tuning/4052-volumized-gas-mileage-trending.html
I'll be able to tell you how much of a difference (if any) there really is. In theory.

 

I try not to let my rpms get above 2k and i dont drive like i'm trying to win any races. My last tank was 20.5 mpg. I was happy with that

 

My last tank was my best ever. I got 17.7MPG, all city driving. My current tank is going to be way less though, and I am driving the same way. I usually average 15-16MPG in the city. I have been using premium (91) for the past couple months.

 

i friggin didnt go above 2k rpms for a whole damn tank and i only got 17 mpg and that was my best tank ever on 93 octane, i think i must have a 7.8L v6 or something

 

The other thing you have to consider is how many miles are on the truck and how well he engine has been broken in. If I keep mine below 2K RPMs in pure city driving (surface streets only) 18 mpg is the highest I've seen. My truck has 2600 miles on it. I'm hoping that by 10K miles I'll be able to squeeze 20 mpg out of it. Also, with winter coming on that should help. Cooler air in the intake and less AC usage.

 

i NEVER use the a/c and i have 15,400 miles...
