No more V8 in F150?

None of the new Toyota trucks have timing belts in their motors, they are all chains. Why does a timing belt make it not a true towing motor? My understanding is the hardest thing on the timing belts is when you start the motor. I have an 06 tundra ... 4.7 with a belt and tow with it all the time. Its not a great towing truck, but that has more to do with suspension and brakes than available horsepower.

It's about bloody time. The last time it looked at a Tundra, it was belted. Now they need to work on the crap mpg.

How many timing belts do you see in heavy duty equipment? Trucks, tractors, construction equipment? None.

All the Tundras have had chains since 2010 and the 5.7's have had them since 2007. Its been a while since you looked ... Comparing a tundra to heavy duty equipment doesn't answer my question about it not being a towing motor. Apples and oranges ... We are talking about a truck rated to tow 7000 pounds. Is there something that makes the belt unreliable under load? The only disadvantage I know of is they need replaced. But, if you follow the maintenance schedule ... they are perfectly reliable. I just don't get the argument.

And yes, their mileage does suck ...

Toyota aimed their trucks at the grocery getter/soccer mom crowd, Obviously Toyota saw the light and went the chain route. If you want to compete with trucks, lose the weak link and build it like a truck.

And my heavy equipment point is valid, belts are not used for a specific reason, they can slip under heavy compression whereas a chain won't. They exact reason for their short replacement interval.

I disagree ... back to 5.0 Fords ...

That is some of the worst logic I've seen in a while. Wow.

The one thing I like about the 5.0 Ford is that it doesn't have that cylinder deactivation crap on it.

But will it out last them? Jury is still out since it was tested in a lab with no real world numbers. Toyota is not a true towing engine, their timing belts are the weak link.

Wow, old pushrod crap, single cam in valley vs twin over head cams and 4 valves per cylinder. Not sure you know what makes a modern engine. HS

I would attribute this to traction. All else being equal, a heavier vehicle has more traction.

Not actually, it's about controlling wheel spin. I have a video somewhere of a jacked up Dmax wit stacks getting tugged around by a All Wheel Drive Volkswagen.

I see early 2011 and 2012 3.5 Ecoboost trucks for sale withe 250,000 plus miles. I would say that's as good as anything else!

I don't think you will see it any time soon.

About 10 years ago I flew a very high up at Ford named Rick. The company I worked for made glass. Anyway, I told him I loved my 07 F150 but wished it got better mpg like the GM trucks with displacement on demand.

He looked me straight in the face and said don't you think Ford could make it if we wanted? He said they tested it and looked at GM's systems, Honda's, and others. He said there were just too many issues like sticking rings, ect.
