Spy Shots: Ford's new "Coyote" 5.0L V8 caught in F150 engine bay
by Sam Abuelsamid on Sep 30th 2009 at 5:40PM 
PickupTrucks.com has snagged photos of a Ford F-150 powertrain prototype with a brand new engine under the hood. And if the rumors are to be believed, it's the new 5.0-liter "Coyote" V8 due to debut in 2010. The Coyote is thought to be a twin cam, four-valve per cylinder motor with an output of 400 hp and 400 lb-ft of torque. The new V8 will replace the long-in-the-tooth modular V8, joining the 6.8-liter V10 it's derived from.
The 5.0-liter will be used in both the light duty F-series pickups and the Mustang, and it should be interesting to see if Ford markets the EcoBoost V6 in trucks against the V8 when they're outputs are so similar.
Pickuptrucks.com also notes that one of the trucks was equipped with seven-bolt wheels, indicating a heavy duty payload version. This fits with comments made by Ford at the launch of the new F-150 last year, where Ford's marketing people indicated that some buyers whose needs were on the edge of the Super Duty were actually moving down to the F-150 for lower cost and better fuel efficiency. A light duty truck with an enhanced payload would help bridge the gap to bigger trucks, giving buyers more options.

They need to put that engine in the mustang now.Burr Aye Okay

A 5.0 liter engine cannot make 400 torque unless it is forced induction or has about 530 hp or more.
You cannot come up with a single 5.0 liter engine that has 400 torque naturally aspirited.
If the engine makes 400hp than torque should be about 340.
I am talking from knowing a thing or two about engines. I am not anti Ford or whatever.

You are correct. 400 torque is possible from 5.0 liters but the hp will be over 500 atleast.
Jordan 5:57PM (9/30/2009)
Well to have 400 torque the engine would rev to 8000 rpm and make 519hp.
More like a ferrari engine than a truck engine. I am guessing it is a typo.
The formula for Naturally Aspirited torque is
T= 5252 X HP divided by RPM
a 5.0 from BMW M5 makes 398 torque. this is the closest example i found but it has to make 500hp at 7600 rpm to do it.
The 400hp for the Coyote is true I believe but the torque is somewhere around 330-340.

VW's W12 was 450hp and 415ft lbs torque and that's 10 year old technology... And it's tech was based on the VR series from almost 20 years go. It's not unreasonable to think that you can achieve similar numbers 10 years later with 20% less displacement and a much more advanced engine, particularly direct injection.

Engines that make 400lb-ft of torque in NA form are all over 5.6 liters:
Titan 5.6 401 lb-ft
Tundra 5.7 401 lb-ft
Sierra 6.2 403 lb-ft
Hemi 5.7 400 lb-ft
even the DOHC 32 Valve mercedes S550 V8 5.5 liters makes 382torque
ckm 6:12PM (9/30/2009)
BTW, the numbers for the W12 are at 6000 and 2750 rpms, respectively. I should point out that it's relatively easy to modify ECU maps to turn down numbers. Porsche does this to tune motors to market segments.
Patrick 6:29PM (9/30/2009)
Are you kidding me? You ranked this tool up?
Hyundai's new 5.0 Tau V8 is rated at 394hp. And that's just the first thing that came to mind to shut you up. What an ignorant comment.
ForgedInternals 6:42PM (9/30/2009)
Ford's modulars always go for more torque than horsepower. The 3v SOHC made 300hp/320 in the Mustang and the 4.6l DOHC made 310/335 in the 04 Mach 1. If this is a DOHC w/ direct injection it could make around the 400lb of torque. It should be noted that the article says thats whats it's "thought" to have so thats not official numbers, The article also claims it's a 4v twin cam and those Cam covers are not wide enough for that.
Sean 6:46PM (9/30/2009)
Patrick are you a retard?
how much torque does the Hyundai engine make? 333?
I rest my case. idiot.

You clearly have ZERO idea how power is made. HP comes from torque (as well as RPM), not the other way around. Torque is the baser unit since it is irrespective of time. The issue is if an engine can be efficient enough to offer near-peak torque over a wide range of the revs for the sake of acceleration or hauling. But as for your calculation, here's how it's done properly.
RPM*Torque = 5252 *HP => RPM = 5252*HP/Torque = 5252 *400/400 = 5252 RPM.
Since torque and HP are equal at peak (and we are just assuming peak torque occurs near the same RPM as peak HP which it should since it is at 5252 RPM that these two become equal and this isn't going to rev very high), then such a situation would occur at 5252 RPM. Not that hard. This does not mean that the engine will ALWAYS put out 400 lb ft of torque nor that it will always put out 400 HP. Peak numbers occur at different places in the rev range but for simplicity's sake, and because this is a low revving truck engine, this is how a dyno would likely figure out a spot on the engine's dyno graph.

A cross plane crank V8 truck engine won't make 80ft-lbs per liter. Ferrari's new 'claim' of 88.5 needs to be verified.
70ft-lbs / liter is probably about right.
350hp 350ft-lbs is enough with the 6 speed automatic.
Mike 8:28PM (9/30/2009)
Sorry to break up this all-knowing engineer fest here but Ford already has a 5.0L engine that makes 400HP and 400lb-ft.

Been around since 2005.

That is not a production engine, but a 'race' engine. (no emissions, durability, NVH, BSFC, tractability, cost, etc. etc. etc.)
Who verifies that quoted power/torque?
JF 9:24PM (9/30/2009)
@ Jordan: I'm a bit curious as to how you calculated your 519hp at 8000rpm to make 400ft-lbs, could you clear that up?. Maybe the coyote engine has an unusually long stroke that allows for greater torque figures when compared with other 5 liters engines but prevents it from revving high enough to produce 500+ hp.
rooster 10:19PM (9/30/2009)
Current 5.4 is 390 ft-lb, 310 HP. Making 400 in 5.0 with dual cams, etc. isn't out of the realm of possibility. And if it's at low RPM, the HP will not be 530. HP is a function of torque and RPM. Completely ludicrous post.

"The article also claims it's a 4v twin cam and those Cam covers are not wide enough for that."
Sure they are. eyeballing the photo, they look similar to the width of the cam covers on the Duratec 35. Really depends on the valve splay and the tappets.
MikeW 11:25PM (9/30/2009)
5.4 V8 is 365ft-lbs
390ft-lbs is what Ford says on E85
naggs 11:28PM (9/30/2009)
we are talking about an all new dohc v8 5.0
the old 3v 4.6 made 300hp/320 tq
if you scale that up to 5.0 you get 326/348, think about dohc full vvt heads and what they would do to those numbers. i really dont see a reason why this engine cant hit 400 tq epically if DI is on the table
Jake B 5:32AM (10/01/2009)
I think the power and torque figures are reasonable.
Hopefully it is immune to blowing spark plugs out of its heads. That would be great I might buy another F-150.
