11,000 miles
I love this 2.7! Zero problems and pulls my Jayco Jayfeather 23RB (5K pounds) effortlessly. Averaging 22MPGs. I wouldn’t hesitate to get another one.

[QUOTE=koach;6202933]Not sure I buy into the weight vs power comparison. Inherently you're going to have X mass for any engine. Plus, not sure about the other engines, but I've read that the exhaust manifold is integrated into the block of the 2.7 so that could explain some additional weight./QUOTE]
Exhaust manifolds are built into the heads not the block. Because of this they are also water cooled keeping the the turbo temp down as well. As for weight having the manifolds integrated into the heads should save weight vs having a bolt on part. The best part of the 2.7 even though it makes it much heavier is the CGI block instead of aluminum. CGI -Compacted Graphite Iron block, offset connecting rods, bowled pistons, reinforced ring seats and more are all diesel inspired features that make the 2.7 one tough little engine. Note of interest: The Cummins and Powerstroke both have the offset connecting rods. The Duramax uses standard passenger car configuration and is not as beefy as the other two.

Does the second gen 3.5 eco have all these updates. https://cimg7.ibsrv.net/gimg/www.f15...185cf3c41d.png |

Proof you spend too much time on automotive forums.... I'm convinced this is exactly what MOST people do....drive by a random dealer, pick the pretty color.
In my day-to-day public life, I find most people pretty clueless. (disclaimer: I do not believe the poster actually did this, but I agree with his point.) |

Added more comparisons to the 3.0L diesels in the half-tonne class. The 3.0L diesels now output more torque/L than the 2.7 ecoboost.

They seem to have mashed together facts from both engines. As far as I know the 3.5 does not have CGI and the 2.7 does not have electric actuators while the 3.5 does.
