4.6 or 5.7 ???

[sskingquad]

Would like some serious input regarding my question please. I am going to buy a trd tundra and have driven both the 4.6 and 5.7. Obviously the 5.7 has more power but I found the 4.6 to work very good as well. The price isn't much different only $1000 bucks but the 4.6 is going to give me better fuel economy. Imostly am leaning toward the 4.6 but most of the forums are leading toward the 5.7! Therefore i am 2nd guessing myself. Is it just a guy thing to lean toward the most powerful animal or am I missing something.

I have a 08 crewmax, 2wd with the 5.7. As long as I'm doing around 55 to 60 I stay around 18 to 19mpg. In the city it stays around 16/17mpg. When I'm eating fords and chevy's it goes to around 14mpg. It's all about the power baby.

Eat this.....bring your wallet.

Don't think you'll find a big difference in gas mileage. The 5.7 has a 6spd trans, and some other pluses. If you're even thinking of towing anything, get a 5.7. Resale down the road.......if none of that is important and you get a big discount, then get the 4.6

Real world gas mileage, you won't notice the difference at all. I'd go for the 5.7, and I'm a chick

So VMAX2007, would you like to be breakfast or lunch?

I have an 09 Crewmax 5.7 4x4, an SR5 with 18 inch wheels. I have managed 18.7 all highway, very easy on the throttle, cruise at around 60-62 mph. I imagine 19 would have been doable had I kept it closer to 55 mph but I just can't stand going that slow.

Alot of people took the window sticker as gospel and snapped up 4.6 trucks as soon as they started coming out. A good number of those people ended up complaining on the various boards about how when you drive them like most people actually drive in the real world instead of how test drivers do to calculate EPA ratings, you end up on the lower end of the range of EPA ratings and they don't consistently return the stellar numbers everyone has been led to believe. In the real world with comparably equipped trucks a gently driven 5.7 can match or almost match a 4.6 for fuel mileage. It probably has to do with the fact that the 5.7 works so effortlessly that it's barely breaking a sweat on light throttle.

So look at it like this...depending on how I drive the bigger engine I can get the extra 2-3 mpg. Once I pick a 4.6 that 70 extra horsepower is gone and it's not coming back no matter what I do.

I almost always hit 18mpg hwy on every fill-up for our 2011 5.7L 4x2 Double Cab. This is very close to what we were getting (19-20) on the 2003 Honda Pilot V6 we traded in. We don't do much city driving, but when I've tanked up after SOME city driving, the fill-up computed out to around 16mpg per tank.

We went through the same angst when we bought in December, and while a 4.6L will easily tow our 3600 lb camper, spending $1k more for a better (IMHO) and stronger engine, was worth the 1-3mpg difference in savings. Since the rated gas mileage differences for a double cab are only 15/20 vs. 14/18, you’re only saving 1mpg in the city by taking the 4.6L. The tank holds 26 gallons, so even if gas hits $4/gallon, you’re going to pay $104 per fill-up with EITHER truck; you just get to drive 26 miles less on that $104 fill-up. That's what...one trip to work? Having the bigger engine was worth 26 miles less out of a tank that I figure I can get 400 miles on (haven’t tested that yet, as I always top-off at close to 325 miles).

I wonder which he bought if anything

I have found the above site to be pretty good. I lists the EPA mileage estimates, and individuals can also input their real world mileage.

Get the 5.7 or fail
