2015 Edge 2.7 only choice?


12EdgeSport

Recommended Posts

I own a 2012 Sport with a 3.7 and love it. Decided to check out the ford website and the info for the new 2015 Sport. First, I'm not a big fan of it looking so much like a Santa Fe and especially the rear design looks a little funky. A lot of times things look different in real life so willing to wait. But the real disappointment is it appears the only engine option is a 2.7, even on the Sport model......what's up with that? I checked the 2015 MKX and noticed it still has the 3.7. If that's the case, my money goes to Lincoln even though the interior stuff gets a little gawdy. Keep the green stuff on economy models dude......don't need your rockin chair or your medicare.

It's an EcoBoost 2.7L V6 that should be considerably more powerful than the outgoing 3.7L.

 

The 2015 MKX still has the 3.7 because it's the same older modern (from 2011), the new MKX, based on the 2015 Edge is expected as a 2016 model. So only the 2015 Edge will be new.

 

And don't be surprised if the 2016 MKX comes with something much better than the Edge as it is the higher end vehicle & costs more.

The engine isn't the issue, it is what is attached to it that's the issue. You could probably get a few more ponies out of it with a tune, but would have a hard time putting it to the ground. Right now, you can squeeze out 25-35% out of a 3.5L EB TT with only a tune, but then the trans has proven to hold up to it. Not the case with the Edge AFAIK. The PTU is still the weak point, so maybe going with FWD might be better for performance-seekers. The amount of fluid in the PTU is just laughable, assuming it is even filled correctly at the factory.

In case it's not obvious by now the 2.7LEB puts out close to 325 lb/ft compared to 285 on the 3.7L so that's quite an upgrade.

It's 325 hp & 375 lb/f for 2.7L EB compared to 305 hp & 280 lb/f for the 3.7L. Also note that the 2.7 EB numbers are for the F150, the Edge's are still not announced, and since the Edge has a weaker tranny (compared to the F150), torque is expected to be limited to 350 lb-ft similar to the 3.5 EB in the SHO & Explorer Sport.

My guess is product differentiation. Can't have the same trans in the Edge as in the Explorer/Flex. Why have we been limited so far?

 

Huh? The Explorer and Flex both come with the 6F50 when you don't get the EB (Explorer gets the 6F55 on the NA 3.5 if you get the tow package). And what kind of customer would ever care that their transmission was "better" than the one in a different Ford model.

 

Ford chooses which transmission to use based on torque limit and durability requirements. They've obviously determined that the 6F50 is good enough with the 2.7, so that's what you get. Perhaps they've beefed it up a little vs the older model though.

That's exactly my point. The mfr will generally choose what meets their requirements, not the requirements of performance-minded drivers. In the case of the 6F55, though, there seems to be quite a bit more headroom than on the 6F50, should you choose to modify.

 

The choice of engines really is irrelevant in the overall picture, NA or EB. Simply the mfr's choice how much they leave on the table for the owner to tinker with.

Ford would tell you that there is no headroom on the 6F55 with the 3.5EB. That's why the EBs with the 6F55 never got the upgrade to TiVCT that the F150 has.

That's exactly my point. The mfr will generally choose what meets their requirements, not the requirements of performance-minded drivers.

 

Or to say the exact same thing in a different way, the mfr will generally not require all customers to pay for something that the vast majority will never use.

Agreed. I don't know if there is a huge base of tuned Edge/MKXs or not, very rare to hear anything about these particular vehicles/transmissions. Do Fusions have the 6F50 on any trim level?

 

However, there is a fairly substantial base of tuned SHOs running 400 AWHP (290 or so AWHP is stock) or more with no changes to the transmission (6F55). This is with a tuner with very close ties to Ford. Hence my comment about headroom differences.

The performance of the 2.7 with 350 ft-lb of torque at 2750 rpm is going to vastly outperform the 3.7 in 0-60.....my guess the 0-60 times are gonna be mid 5 sec.

 

With 350 ft-lb that early in the power band, the trans in the new edge will have to be beefier than the old trans in the 3.7.

It's not all that early. On the SHO, the full torque hits at 1500 rpm :) This is way BEFORE torque converter lockup. On the Edge, I believe it would be somewhat AFTER torque converter lockup with stock programming. That should keep demand on the trans stable.

 

Don't know what the Edge's hp/tq curves will look like, but this is for the SHO:

18ncqzus8dxwqjpg.jpgThe 3.7 did not hit max torque until 4000 rpm.....so 25 % less torque and a gradual delivery would make distinctly less stress than the 2.7.

If the 6F50 can't handle it they'll just use the 6F55 from the 3.5L Ecoboost Explorer, Flex, MKT, MKS and Taurus SHO.

From the owners manual, the 6F55 is one of 3 transmissions available on the Edge. So I'd think this is a confirmation that the 2.7 comes with it.

Thanks for the info omar32

Sweet.....the order code on my 2015 sports trans is 44c.....guess the " c " was the 6f55.......i knew they would need the heavier trans with 350 ft-lbs of torque.

Actually, due to the 6F55 torque limitation (though it is still higher than the 6f50), it seems that the 2.7 is like the 3.5 Ecoboost where they have both been limited to 350 lb-ft of torque while in the F-150, the 2.7 is rated for 375 lb-ft & the 3.5 is rate for 420 lb-ft (and up to 460 in the 15' Navigator).

Good catch, omar! So the 6F55 mated to the 2.7EB should open up tuning possibilities like they are on the SHO. I wonder if there have been any changes to the PTU design though. No meaningful changes to service intervals that I can see.

 

Same spark plugs for the 3.5L & 2.7EB. Wouldn't rely on the 100,000 service interval for optimal performance in the EB, 30,000 miles is a more practical interval due to gap growth (to which turbo engines are more sensitive).

 

Waiting for comprehensive maintenance schedule data to be published:

Don't forget there are differences in the intake and exhaust in the Edge versus the F150 due to the Edge being transverse mounted. This can account for some of the power differences. But given it's exactly 350 and the same as the 3.5L EB engines I think it's safe to assume they're doing the same type of limiting.

I belive It is all in the tuning. ....since the mkx is running 330hp and 370ft- lbs of torque. Just with tuning I believe these engines have a much higher ceiling. I wouldnt Be surprised to see 380hp And 400ft-lbs + ...with just a good tune.
