Someone mentioned in another sttring below that Toyota rates gas mileage for both of these engines about the same. That's true. In fact, some figures show the 5.7 to actually get a mile-per-gallon better than the 4.7. Go figure.
With that being the case, why offer the 4.7? Is it purely a cost issue (cheaper to manufacture and therefore cheaper for the customer to buy)? Or could it be that Toyota feels that its 4.7 is a proven and reliable engine and wants to keep it in the line-up.
I cannot see where the 5-speed vs. 6-speed tranny would factor into it. All things being equal, who wouldn't want a 6 speed? Nor do I see an issue with the bigger ring gear being fitted for 5.7 models. If gas mileage is just as good or better, why not have that monstrous rear end gear?
I'm sure the 5.7 has been tested thoroughly, but we won't know the real verdict on that engine until about a year into production.
Well, the 5.7 probably gets *slightly* better mpg during normal driving thanks to the extra overdrive gear with the 6-speed transmission. But those drivers with a heavy foot will get better mpg with the 4.7 than the 5.7, because if you get on the gas hard, the 5.7 will start consuming lots of fuel.

I think the 5.7 was also made to be more efficient as it has a different intake and exhaust set-up. I agree though that someone who doesnt need the extra power can buy the 4.7 and get better gas mileage than someone like me who would get the 5.7 and drive it a lot harder.
I'm just wondering how quick a 4WD 2007 Tundra Shortbed Regular cab would be with the new 5.7L V8. If the larger, and heavier, CrewMax gets a 6 second 0-60, would the lighter and smaller regular cab be much faster?

I heard on the Speed Channel that the a new Tundra 4WD 4 door with the 5.7 did the 1/4 Mi. in 14.8 sec. Eng. is rated 381 HP & 401 Lbs. of torque. Now thats what I'm talking about!!!

Hells yeah!! If I WERE to get a 2007 Tundra, it would likely be just the regular cab shortbed 4x4. I don't use my backseat much and the new Tundra is wide enough across to seat three reasonably comfortably. Plus, like the new F-150, there is extra space behind the seat to hold stuff.
