This is the second golden age of muscle cars. We are reliving 1970 all over again. 1972 will be here before you know it.

This comment is spot on.

The transmission and "transfer case" couldn't handle the power of a truly "boosted to the max" V6 that Ford has. The ecoboost is not at its peak. Plus even if those items could handle it, then people would bitch about using 93 octane only gas and still get poor gas mileage from it and the gas guzzlers tax that would be slapped on it. Like all automakers, its a balancing act between power and meeting the EPA fuel guidelines.

If it's that big a problem for you, don't buy the V-6. Go get the Hemi. Or wait for the SRT. Or just go get a drag racer and be done with it. Expecting high fuel economy with tremendous power and acceleration out of a vehicle like this is just foolishness. Given what the competition has accomplished, Jeep has not done badly at all.
At least with Ford a few years ago, their cars needed premium or else you would get a bad case of the knocks, not now. The V6 is just as quick with normal old 87 has it is with 91 pump gas. Don't know why you would think that it would be a problem with me lol. Why would I want a 5.7L that is slow, require more maintenance, and require more fuel when you have a V6 that has more pick-up, far less maintenance, and yet can get 28 MPG on the highway.

Sorry but as much as I love Chrysler, I have to be real here, the Ecoboost is just a better engine.

Ford like to rush new things out to the market. Sometimes it work, sometimes it doesn't. When Ford was making the 4 banger Ecoboost I think it was being made for the 2012/13 Ford Focus, the now doomed Ford Ranger, and the Ford Fusion/ Lincoln MKZ. Now its going to be put in the Explorer. I'm sure when no one buys the 2.0L Ford is going to realize that the engine is too small for the car and would remove it.

I'm still not convinced. Strip off the turbos (a more equal comparison), and the Pentastar generates more power that the Duratec 35. We'll see how the Pentastar does when it gets direct injection, and maybe even turbocharging. I don't deny a turbo would help with high altitude performance, but I am not quite of the opinion that wringing all the possible power out of a small engine via forced induction is ultimately as good a method as just using a larger engine and not working it quite as hard. I've just yet to see too many turbo gas engines going 150K+ miles.

Re: test drive v6

Now you want to strip the turbos which wasn't even part of the debate lol

Ok, lets talk about the 35 which depending on the car can put down 263hp/249tq-283hp/251tq while mated to a 6 speed transmission when the pentastar put down once again depending on the car 290/260tq-305hp/269tq when only mated to a 5 speed transmission. Given the same car, odds are is that the two engines would make the same car just as quick while giving out the same about of gas mileage. However, if you want to also throw in the Duratec 37, then the pentastar would be out matched again.

Re: test drive v6

Also, Ford claims that the Ecoboost can go up to 150K.... I'm starting to think that 150K is the goal for automakers today.

Re: test drive v6

Those are crank numbers so its not "putting that down", so to speak, and the transmissions are irrelevant really. As far as ecoboost is concerned... ::yawn:: wake me up when Ford straps the turbos on their new 5.0 or 6.2 V8s

Are we talking engine vs. engine or not? Yeah, IF you run an equivalently sized and equivalently modern engine with twin turbos, it's going to outperform the naturally aspirated competitor.

But comparing a forced induction engine to an aspro and using that power difference to claim that one is somehow more advanced than the other, you are using one single metric that isn't even comparable and letting it stand in for ALL features. Weight of the engine, cost of the engine, longevity (neither has been around long enough for longevity to be properly measured), those all come into play.

The engineers I hung around with when at GM always said that trucks were engineered to go 200,000 miles before a major overhaul was required. Usually, engines meant for trucks were heavier duty (5 main bearings rather than 3 mains in the V8s, for example). Today with longer powertrain warranties and shared platform components, I'm certain the design goal is 150,000 miles across the board...minimum.

The engineer chat said that the WK2 powertrain was engineered for a 150,000 mile life.

Re: test drive v6

^^^^

That was why I thought that was the new goal. Mainly because 1st owners of cars doesn't keep their cars pass 100K.

Also, I was wrong about the 2HP gain using 91 pump gas. That was for the 3.7L in the Lincoln MKS. There is no record of the gains/loss for the Ecoboost. But I still stand by the engine running just as well with 87 vs 93 as I drove the SHO in both forms.

Re: test drive v6

With my previous GC Overland with the 4.7L HO engine, the manual states power as 265HP on 91 octane and 235HP on 87 octane. Either may be used.

This power diff according to octane was in the manual? If so, it's wrong.

10 hp difference (at best)due to the advance timing you get with the higher octane.

There's a lot more going on in the HO engine than a tune.
