I wouldn't call it horrible. When I pull a load or haul something, my mileage doesn't drop near as much. It's comparable to my buddy's Hemi Ram and my brother's Ecoboost 150 when they work theirs. Besides, I couldn't care less about fuel mileage in a pickup truck. If I was worried about mileage I'd drive a Prius and just rent a truck when I needed one. I prefer reliability and durability. I've owned gas trucks by every manufacturer except Nissan and no gas engine made by Ford, Garbage Motors, or Fiat compares to the 5.7 Toyota.


You can't get more than 20 mpg on the highway in the Tundra (with the 5.7). The 5.3's in the Silverados will easily do mid 20's with the AFM active and if you keep them at or below 70ish mph.

Yeah you don't buy a truck for mg-that being said 25mpg is better than 20mpg.
 
For reliability reasons Toyota likes to stay under 100 hp / liter in their mass produced offerings so expect some sort of supplemental power with this configuration. Plenty of space for an electric motor.

The Tundra V-8 is a great engine. Smooth, powerful, sounds awesome when you open the throttle. I can tow a 7,000# trailer and the engine barely notices that it's there.

The Hemi makes more HP, but it's 395 vs. 381 for the 5.7. And 420 vs. 401 torque. Not a huge difference. The GM 5.3 is down a little at 353/380.

Yeah, the Tundra gets lousy MPG. But that's because It is a heavy truck. Further, it doesn't have AFM, or radiator shutters, or any other gimmickry to extract a few MPG.

And that's why I bought it - none of that stuff to fail in the years down the road.

When I was shopping a few years ago, all of the trucks were nice. I thought the Ram drove the best, but the Silverado and the F-150 were really nice, too.

I chose the simplest V-8 of them all because, frankly, that's what I wanted - a straightforward, powerful, V-8 from a company with a reputation for reliability. Let me add that I was replacing a 1990 4 Runner, which, ironically, also got terrible MPG, but is still on the road with its new owner and has 300,000 miles on the original power train.

I have no fear of turbocharging. Check my signature, there are 4 turbo cars in my household, all running original turbos and some of them with over 200,000 miles. But for my truck, I wanted a V-8. A V-8 with no gimmicks like AFM. Fuel economy was the least of my concerns.

I love the Tundra's 5.7. It's a great engine. I will be disappointed to see it go.

Fully agree, even the old school non-performance V8 engines of decades ago (GM 350, Mopar 318, etc.) would keep chugging along for that many miles, they never seemed to die even if they burned prodigious amounts of oil as they got very old. Usually the car or truck would rot away long before the engine wouldn't run anymore.

My son has an Avy w/AFM and its about to be disabled bc it causes problems. Yes the 5.3 feels and IS underpowered for that large of truck. Main reason the Tundra gets lousy gas mileage is that its made to haul and tow. That rear end ratio is a mileage killer.

Toyota should explore using the 4.6, upgrading it for better mileage and more power..perhaps a mild hybrid. Right now, my avg fuel mileage on the Tundra sits at 17.9/ Not bad

Yes the FORD v6 turbo is more powerful than there V8 but will it go 250+ without turbo repairs ?

What makes you say they won't?

True, but 95% of all vehicles are in wrecking yards or somewhere in Mexico before they hit 200,000 miles.

All I can say is, get one while you still can.



Titan V8 and RAM Hemi still old school non turbo and non DI. I think, after having driven every truck available that the Hemi 5.7 is the smoothest and best MPG V8 available. Followed by the 5.3/6.2 GM's and Ford EB motors. Titan and Toyota never came across as anything "special" but nothing bad about them either.

If they figure out how to shove one into a Fiat 500, maybe they'll get my interest

Yes, that is the reason for the change. Those wonderful V8 Toyota engines are among the most thirsty around. Every bit as bad as my Ford 5.4L 3V.

I have 3 F150's. All SuperCrew. The 5.4V8 gets 13mpg, the 3.5EB gets 18 and the 2.7EB gets between 18 and 20 depending on gas quality (winter/summer) and conditions. The 2.7 is the fastest of the 3 trucks too.

I was amazed by the 2.7 I had rented also... Crew Cab 4x4, I cued it up in 4Hi with my GTech Pro (remember those?) and ripped off a 6.2 sec 0-60 run with it. In other words, if you're in Tony Schumacher mode and not sleeping on the light, you can probably get out in front of 90% of the vehicles you encounter every day on your commute. I did mostly highway driving while I had it for about 700 miles, and hand-calculated a 25.1mpg average for my time with it. I was quite impressed by everything except the sticker that was on the wrong side of 40k. I'll buy one in a couple years when they're under 20k.

What's the ratio? we have 3.92's in the pots of our RAM sport and with the MDS, it still ticks off excellent fuel mileage unloaded. I'm sure the lovely ZF 8-speed has a role in that as well however.
 
Tundra's V8 is very durable, but that's it, and that's just not enough. Glad to see them getting with the times. Back in 2018, Dec. I was looking for a new vehicle. I checked out the 4 Runner, Taco, Tundra, and all of them got absolutely horrible mpg, while still not being fast at all within their classes. I ended up replacing my 2015 Mazda with a 2019 Mazda, and the RAV4 Hybrid seems to be a failure also, in every way EXCEPT the mpg department, so I'm still glad. This new V6 TT though...maybe it could find its way into a Supra...JS

Hint: If you pay anywhere near the sticker on a 2.7 F150, you were taken on the price. The 2.7 is a staple in XLT trim trucks - and 10-12k off of sticker is normal for an actual sales price. MY truck stickered at over 52, and I bought it for just under 38 before trade, TTL.
 
Never had the pleasure of driving the Toyota 5.7 V8 but it sure seems to be a solid motor. Toyota is making a Huge Mistake by not offering it as an option in the Tundra. There are many people who want & require a V8 in their trucks for their needs especially if you plow snow. Sure the turbo V6 will have more power but that's Not what the average truck buyer needs or wants . Most 1/2 ton truck owners tow under 10K pounds & the good ole reliable V8 suits their needs just fine! Huge mistake Toyota you just lost a bunch of customers to Ford , Ram, & GM who offer V8 options!

Ironically, that was what everyone said back when Ford started to offer the Ecoboost in the F150's. (I'll grant they at least still offer a V8). Fast forward to today and Ford sells more ecoboost trucks than V8's. Less than 25% of F150's sold today are V8 equipped ... Though that is still more V8 equipped F150's than the total number of tundra's sold in 2019 anyways...

I'm not here to bash the Tundra - it is a solid reliable truck. It is seriously overdue for some updating though - and the powerplant is one of those areas that it is time to improve upon it...

Maybe Toyota just needs an 8 or 10 spd, play around with gearing, engine management and go with direct injection.

They already have both 8 and 10 speed automatic's, plan to have them in 60% of the fleet by 2021. The 8 speed auto is already in the Lexus LX570 which has the same 5.7L UR engine, so we know the 8 speed at least can handle the torque of the V8.
