Toyota Tundra EPA MPG ratings

Why does the Toyota website show 14/17 for the 4.7 and 14/18 for the 5.7? How can the 5.7 deliver better mpg as it has way more torque,hp and a lower rear end ratio?

Are these the new (supposedly) more accurate EPA figures?

    I believe the mpg differences are related to the fact that the 4.7L has a 5 speed transmission, while the 5.7L comes with a 6 speed.

    ANOTHER REASON COULD BE THAT WITH 100 +/- HORSEPOWER WITH THE NEWER V,/8 THE ENGINE IS WORKING MUCH LESS TO PULL THE TRUCKS WEIGHT AND THEREFORE IT USES LESS GAS. :)

    My 2000 2wd 4.7L access cab gets 19 mpg no problem. Maybe the truck is now heavier, did you check that out?

    I very much doubt that you are getting 19mpg with a 2000 model 4.7 V8 - unless of course you are driving downhill everywhere you go.

    I owned the same truck for 2 years. I averaged 14.6 mpg on the hwy. Which was only about 50' above sea level. No Hills.

    Welcome to edmunds forums tommy1234!
    Here's the governement window sticker EPA mileage link that says 18 mpg.

    Maybe 1 mpg better is way out of line as time passed, I don't know. Could've ham fisted the calculater buttons maybe too - I guess. Not too worried as I have a '91 Toyo pickup with the 4 cyl 22re now.

    79K miles, just broke in! Tundras are great trucks though.

    FYI, I just completed a 6500 mile trip to/from Texas. Drove 75 mph typical on Interstate and did ~95 mph for ~2 hours of the 4-month trip. My 2000 SR5 4.7 liter V-8 averaged 17.7 mpg over the whole trip. I carried about 1250 lbs load at all times and did considerable off-roading in West Texas hill country. (Ran circles around two 2006 Chevy trucks by the way.They kept hanging up because of lower ground clearance.) Around Lake Tahoe (6000-6500 ft. altitude) I routinely get 17 mpg, but it has been as high as 20.5 mpg. Most of my driving is in the 60-80 mph range.

    Sounds like you had a great trip mikon. I used to 4-wheel around the Pacific Northwest a lot. There's a ton of mountain roads. But I really seldom needed it. I got through everything with 2wd and only got stuck in a 4wd. Couldn't resist going where I shouldn't have.

    My 2wd Tundra never failed me.

    Wished I had a 4wd Tundra once- towing a trailer up a gravel hill to a MX track once. That was nasty.Toyota sponsors MX and Supercross events, and that aint nasty.
