Did it ever occur to anyone that when they add something to a vehicle, it can serve more than one purpose?

Have that part right but if you don't think it has aerodynamic effects you are crazy. Why else would gm be looking at them for na cars and the future Silverado.

Then why not put them on all F150's if they improve aerodynamics?

Why don't they put hid headlights on every truck since they improve visibility.

Cost. Marketing. Etc.

I'm not claiming they won't help with the issues. They likely will. But trying to decide of they were included for aerodynamic or cac efficiency reasons is impossible. Because it will have effects on both.

Eventually they will be on the 5.0 too

I'd guess cost has something to with it. That and the simple fact that the ecoboost is where ford is going in the future.

The 2.7 Ecoboost is going to be the mpg platform for ford.

First off I know quite a bit about intercooling and turbo vehicles. 2nd I have practical hands on experience about what you happen to be talking about.

I'll ask you in return. What qualifies you to make those assumptions about "boil off" and how this is fords "solution"?

Did you ever stop to think that getting the IC hot enough to "boil off" is also going to create very high charge temps? Which can make the motor prone to detonation and reduced performance.

I'm sure that keeping charge temps low are critical to making this turbo engine run on 87 octane.

So with that I'm sure the active shutters will only be closed at optimal times that benefit economy.

Only time will tell....

Let them hit the lots and get some run time and we will see.

I remember seeing a video of the new F150 that showed a snip of the active shutters and they were only located in the space in front of the intercooler..... the opening in the bumper. The remainder of the grill in front of the radiator and a/c condenser did not have them.

Maybe boil off was a bad term.... What I was trying to get across was that they are trying to keep the intercooler hot enough so that the condensation does not accumulate to begin with.

Again....time will tell.

Take your logical, reasonable opinions and shove them right up your !

yes I'm well aware that grill shut outs and even rim shut outs are used to improve fuel efficiency however if their sole purpose is to improve fuel efficiency why on the world would they include them in their f150 with the most efficient engine and not the ones with the least efficient engine? You seem to think your pretty smart do you understand how condensation works? If you don't cool the intercooler when cooling is not needed you should be able to reduce condensation build up. Previous poster had a plausible theory or are you just a denier that thinks everyone here with condensation issues are just making up these stories to bother you?

The 6.2 is the least efficient engine, which is why Ford is dropping it.


Active shutters together with the 2.7 ecoboost probably will be the most fuel efficient combination.
