Replying to: autokritiker (Apr 16, 2008 2:35 pm) The heads went from 2 to 3 valves and some sort of variable valve timing was introduced. The basic engine design and bottom end are very similar if not identical. You are right about the Toyota example though, the 3.0/3.3 have nothing in common with the 3.5. Ford's 3.5 is considered "all new" however, I do wonder how much of the "old" 3.0 was used. They share the same 60 degree architecture and similar valve layouts. |

Replying to: autokritiker (Apr 16, 2008 2:35 pm) they have little in common while I'll admit to know little about the specific components in Ford's DT engines, and generally will agree that a ~20% bump in displacement is hard pressed to yield a 30% increase in HP, my observations (in an Edge) are generally that the 3.5 is the same DT in terms of refinement as the anemic 3.0 was. This has generally been confirmed in many other reviews of this engine in multiple Ford products including the Taurus. Reference the current issue of CR where they road test/compare the new Accord along with things like the Amanti and Taurus, and you will see the same sort of comments along with a negative comment about the 'new' engine's FE. It does seem that Ford's 'new' DT3.5 while it does give the Taurus competitive power it does not really give it an overall competitive engine in terms of refinement. It may or may not be a simple bore/stroke job or it may or may not be a 'new' engine as Ford will certainly claim but the results are the same - a generally substandard engine IMO especially when you consider that it was 3 years late in coming (it was supposed to be in the original Five Hundred), and in relation to things like the Toyota 2GR, the Nissan VQ and even the Hyundai 3.3/3.8. I would be willing to bet that had Ford been able to get the production of the 3.5 up in time we would not be talking about the 'Taurus' today however - the 500 would still be alive and would have sold much better!

Replying to: captain2 (Apr 17, 2008 5:49 am) The Duratec isn't as silky as the 2GR when you listen to it, but it's also TONS better than the GM pushrods, and certainly not loud or obnoxious enough to be offensive. The top of the class is the 2GR, but that doesn't make everything else bad; just not as "excellent" as the 'Yota.

Replying to: thegraduate (Apr 17, 2008 6:15 am) as almost any DOHC engine should be - but you also forgot to mention Ford's own 4 liter pushrod V6 - recently had the experience of driving one in a rental Mustang - that engine is the one that gets my nomination as the worst of the worst with all due 'respect' to the GM 3.8. And yes, the engines in my Avalon (and my wife's Altima) have definitely gotten me to expect more out of a V6 than simply some HP.
