Ford Fusion Sport’s Tuning Potential



We know the 2017 Fusion Sport is equipped with a 2.7-liter EcoBoost V6 engine and it’s paired with a six-speed automatic transmission. Producing a very respectable 325hp, the Fusion is beating its competition such as the V6 Camry, Honda Accord V6, BMW 340i (by 5hp), etc.

Respectable is great but we can do better.

The Fusion Sport shares the same engine as a few other Ford products and we can look towards those engine tunes to see what the Ford Fusion Sport is capable of with the right ECU tune and exhaust.

The Ford 2.7-liter EcoBoost V6 Lineup:
• Ford Edge Sport: 315hp @ 4750rpm / 350 lb-ft of [email protected] 2750rpm
• Ford F-150: 325hp @ 5750rpm / 375 lb-ft of [email protected]
• Lincoln MKX: 335hp @ 5500rpm / 380 lb-ft of [email protected]

Ford has tuned the same engine differently for each vehicle with the highest at 335hp. So the Fusion Sport inherently has the potential to hit that 335 horsepower but what if we want to go further? Maybe we can look towards what’s already been done to the Ford F-150. The guys at Diablosport claims to be able to squeeze out an additional 30-40 horsepower and 60-70lb-ft of torque from the 2015 Ford F-150 with their tune so we could see a similar power increase from the aftermarket.

Couple that tune with a new exhaust and you could potentially unlock around 375+ hp in your new Fusion Sport.

That extra amount of power as bolded will do us a lot of good in the Fusion Sport, a platform where we'll really feel it, more so if its tuned in favor of the low end... that's going to make city driving a lot of fun.

I've been thinking about this as well...

The 2017 Lincoln MKZ has a 3.0 turbo (bespoke to Lincoln) pushing 400hp and 400 lb-ft. The 2.7 at the same output:displacement ratio would be right at 360hp. The 2.0 and 2.7 are right at the same hp:disp ratio.

The 2.0 4cyl EcoBoost has bore/stroke of 87.5mm/83.1mm, respectively.
The 2.7 6cyl EcoBoost has bore/stroke of 83.1mm/83.1mm, respectively.
The 3.0 6cyl Lincoln may have bore/stroke of 87.5mm/83.1mm, respectively.

The 2.0 and 3.0 have a slight advantage in total hp being over-square, as the stock [email protected] and [email protected] offerings show the same HP:Disp, we should be able to tune the 2.7 to achieve the HP:Disp of the 3.0.

By the way, Full-Race had an article about a 2.0 Fusion pushing 400hp; they swapped the turbo for an otherwise identical unit with different A/R. They also added an air cooler and some non-power-adding items... I bet we could gain something in real world driving experience (even if nothing on the dyno) from a better intercooler. Unfortunately I already asked Full-Race if they would develop anything for the Sport, and they said no.

Enough rambling for now...

That's impressive, 400 is a lot for the street and fortunately with today's technology cars with 1500 horsepower can be practical even in winter! But on a serious note i'd even be happy with less than 400hp, as long as low end power delivery is taken care of.

as great as 400 hp sounds on paper, the OP's original 375hp estimate should be sufficient for me and the stock intercooler probably isn't made to handle that extra boost.

From experience and through the experience of others, it seems around 350 is the magic number for street power, anything more is either too much or a better to some.

For this group, i can't imagine any going well beyond that. If we were talking Mustangs... different story.

I went digging through some magazine tests to get a frame of reference to allow for a “guesstimate” of the performance of the 2017 Fusion Sport.

I compared the performance of the 2015 2.0 Ecoboost Edge AWD to the 2015 2.7 Ecoboost Edge Sport as tested by the same publication.

The performance increases were as follows (from 2.0 to 2.7):

  • 0-60: -2.7 sec
  • 0-100: -8.5 sec
  • 5-60: -2.8 sec
  • 30-50: -1.2 sec
  • 50-70: - 1.4 sec
  • ¼ Mile: -2.0 sec / + 12 MPH
I then did the same comparison between the 2014 2.0 Ecoboost Fusion AWD and the 2015 2.0 Ecoboost Edge AWD using the same publication.

One caveat here: The 2.0 Ecoboost in the Edge is the updated version that uses the new twin-scroll turbocharger. It features new pistons that provide a higher, more efficient compression ratio (going from 9.3:1 to 9.7:1); a newly designed, integrated exhaust manifold optimized for the twin-scroll setup; a new active oil control system; an active wastegate to more accurately manage boost and torque levels; and a new, high-pressure direct-injection fuel system for more precise fuel delivery.

If the Fusion was also fitted with the new twin-scroll 2.0L the performance differences may have been even greater in the lighter Fusion’s favor.



  • 0-60: -1.0 sec
  • 0-100: -2.2 sec
  • 5-60: -1.3 sec
  • 30-50: -0.6 sec
  • 50-70: - 0.4 sec
  • ¼ Mile: -0.5 sec / + 2 MPH
Based on the above data I would estimate the performance for the stock ’17 Fusion Sport as follows:

0-60: high 4 second range
¼ Mile: mid to high 13’s @ 100+ mph

Livernois currently has a tune for the 2015+ Ford Edge Sport.

On the same dyno the measurements were as follows:

  • Stock: 225 whp / 254 wtq
  • Stage 1 93 Octane: 329.89 whp / 369.75 wtq
Some customers have been able to do some vBox testing and/or get in some runs at the drag strip.

0-60
  • Stock: ~6.0 sec (average over several runs)
  • Stage 1 93 Octane: ~4.9 sec (average over several runs)
1/4 Mile
  • Stock: 14.7 @ 93 mph
  • Stage 1 93 Octane: 13.5 @ 101 mph
Livernois also just released an “aggressive” version of their 91 Octane tune that alters the transmission shifts, torque management, etc. It was able to decrease the 0-60 times even further. The regular 91 Octane tune resulted in 0-60 times of ~5.4 seconds. This was reduced to ~5 sec flat with the aggressive version. The expectation is that the 93 Octane aggressive tune would show similar improvements.

Livernois has already stated they are looking forward to tuning the 2017 Fusion Sport.

If they can get ~1 second increases in the 0-60 and ¼ mile times like they did for the Edge Sport we could be looking at 0-60 in the low 4’s / high 3’s with ¼ mile times in the mid to high 12’s, approaching 110 mph.

Starting to think about all the tuners that will come online and offer products and packages for this and I can't help but think about what Hennessy Performance will have to offer us, they're know for some of the best tuning packages on American cars.

Are there any negative side affects of a tune like this? Reduced engine lifespan, etc?
Yes. Something that might not have broken when set at factory parameters may now break (or break sooner) with the modified settings.

But with a good aftermarket tune it is more possible than probable.
