2014 Track pack V6 2015 track pack Ecoboost

[FiveLiterDreamer]

I would love to see a performance pack 14 V6 v. a Ecoboost performance pack 15 comparison. I think that this would show the truth about whether Ford is intentionally crippling the 3.7L or if the ecoboost is truly a better performing engine package.

That's a big accusation against the company that pays your bills.
The EcoBoost 2.3 makes much more torque than the V-6, and maintains it across a far wider range. And more HP. And it weighs less. What's not to like?

Not really meant to be an accusation or a cry of foul play, with the money Ford throws at R&D they could make the one liter ecoboost powerful enough to play in the Mustang (profitable and reliable would be big ?????)... I just was referring to the old adage of there's no replacement for displacement. I grew up basically in love with the tuner scene and thought that cars like the S2000 240SX RX7 Miata Supra R32-R34 Skyline were trump cards and a small displacement high reving sometimes turbo motor was the way to go. Now that I have driven some of these vehicles and driven some other larger naturally aspirated motors I have found myself rethinking my stand. We haven't heard confirmation on the power of either the 2015 3.7 or the 2.3T. Nor have we heard weight specs let alone the differences between power train options.

If the new ecoboost was one pound less and had one more horsepower would you automatically take it over the 3.7L or would you be interested in the way and where the motor makes power and distributes and uses that power to/on the road/track?

The attraction of the EcoBoost motor is exactly what you suggest: the way the motor makes the power and the driving dynamics of a boosted motor. Off-boost fuel economy, and on-boost instant torque and power. That's personality.
The 3.7 was a good motor, but the market is changing away from these types of engines. I've had good experience with this engine: my track group has two Mustangs with it that are used for student instruction, so I've driven them at 100% and they've proven reliable from the standpoint of the engine (not the suspension)... but without much of a personality. Dull in fact.
I've been a big fan of boosted engines, with a 500-horse G37S and a 450 horse Supra TT. Both excellent vehicles all-around, with a lot more fun in the driving experience than my Boss.
Going back further, I had at the same time an SVO and a GT, with very similar numbers but an entirely different driving experience. The SVO took skill to drive, but was faster and more versatile all around. I remember how just a touch on the gas would produce instant passing power on the highway. The SVO was much more fun to drive.
So, yes, I expect that the EcoBoost 2.3 will be a superior engine to the V-6. Even if it weighs exactly the same and only has 1 more HP, we know it has a lot more torque across a far broader curve.

Interesting perspective. I'm the exact opposite. I really dislike the surge of torque from a turbo engine, and greatly prefer the instant response and relatively flat torque of the N/A engine. I plan to get the GT350 version, but if Ford offered a V6 with track pack I'd prefer that over the Ecoboost with track pack, simply because of the (IMO) better power delivery of the N/A engine.

Clearly the world is moving towards forced induction as a way to improve economy, but that is not a trend I appreciate.

At least the US companies still offer some good normally aspirated power.

Although I may still need to take a few test drives in the new M3, even though it does have a turbo engine.

Except there won't be an old-school type of surge with the 2.3EB. EBs use a much smaller turbo than normal and have very little lag. It will be making almost peak and constant torque at just 1700 RPM all the way to 5000+ RPM... something the V-6 can't even come close to.
Remember that we're comparing the 2.3 to the 3.7 here. The 3.7 doesn't have a particularly fun torque curve nor any kind of instant response. That's why I said it had no personality.
And this is Ford's 3.7. Nissan's 3.5 and 3.7 have a lot more personality and are more fun to drive across the rev range than Ford's 3.7 - especially when they are boosted.

S550 Boss is correct the purpose of the ecoboost motors is to deliver a flat torque curve this "tabletop" torque curve is what I believe has helped the 3.5 liter ecoboost sell so well in the F150. Unless you tow with the truck every single day the ecoboost is truly the better motor for most F150 users. the 2.3 ecoboost is a twin scroll variable turbo charger there should be little to no noticeable turbo lag and the motor should have a giant user friendly available power band. staying out of boost I believe that this motor will be a 35+ MPG vehicle. I however do hope that someone does a comparison between the vehicles i mentioned in the beginning of this thread. Obviously the streetability and efficency of the new motor will blow away the V6 but I would like to see them pitted against each other on the track. I also can't wait to see how bullet proof this motor is like S550 has mentioned before the 2JZ motor out of the Supra is an automotive masterpiece of engineering if Ford can pull off something even close to this we are in for some very exciting times.

here is the 3.5L ecoboost torque curves this motor is an absolute monster we've heard rumors of customers making upwards of 700 LB FT with simple mods and revised engine tuning
