2011 F-150 Drivetrain Mirrors the 2011 Mustang
While a lowly pickup truck is hardly of any interest to a car enthusiast, much less a driving enthusiast, they do have value as tow vehicles to get the car to the track. And because the F-150 is paying much of the engine development bills for the Mustang we’ll cover Ford’s latest announcement today.
Ford has announced a new and extensively reconfigured engine lineup for the 2011 F-150.
5 liter: (360 HP/380 torque)When the 2011 Mustang GT was announced, some elements at Ford told the press that the new 5.0 liter GT engine was exclusive to the Mustang, had been developed solely for the Mustang, etc. None of which was true – as shown by some of Ford’s own press materials at the time and by an interesting spy photo showing a 5 liter engine under the hood of an F-150 development mule. And the simple financials of it are that Ford can hardly afford to create a mass-production engine that won’t be used elsewhere. Hence, the 5 liter will show up in the F-150, the Australian Falcon (just a few months off), and probably the F-150 platform variants such as the Expedition and Navigator. And why not – it’s agreat engine (despite the whimpy ratings in truck format).
3.7 liter: (300 HP/275 torque)It’s been known for some time that F ord would supply a new V-6 engine for the F-150, replacing the very dated and lame SOHC 4.6 liter V-8 as the entry level engine. The 3.7 liter engine does that very well. But why the 3.7 versus the 3.5? What Ford needs to explain to us is what the strategy of the V-6 engine lineup is: is the 3.5 liter the base engine and the 3.7 the upmarket option? Or the Lincoln-only option (and just what are the “exclusive Lincoln engines that have been discussed – but not announced – by Ford)? When the Taurus engines are reworked for 2012, will the Taurus get the 3.7 or the 3.5? And why does the Explorer have to make due with the 3.5 when the 3.7 would have provided the same mileage along with more torque and HP (especially useful given the 4400 pound weight of the base model).
6.2 liter: (411 HP/434 torque)this is the all-new engine line that Ford originally planned to offer as a “big block” option in the Mustang. Those plans are long dead… and the engine itself was killed and resuscitated a couple of times over the course of it’s development. You get the feeling that somebody at Ford finally said “enough – it’s developed, so put it into something so that we can compete against the GM 6.2 liter engine”. Anyway, it’s here, and it’s only purpose is to provide enough power to haul a too-large truck around. Don’t expect to see this engine around for too many years. In any case, the only version that ever made it to production was thisindustrial-purpose SOHC model with cam phasing. Not too exciting, but it gets the job done. And, in another marketing mis-step, the engine has a casting inside it’s valley that says ”BOSS”.
3.5 liter EcoBoost: (power not yet announced) this is the most interesting new option for several reasons. First because Ford is positioning this engine as a premium offering, and the open question of the acceptance of the concept by less than technically savvy truckers. The jury is out on that one, so it will be an interesting couple of years. As mileage and emissions standards get further tightened over the next few years, and as the weight and shear size of the F-150 is reduced to match, this may well end up as the only V-8 offering by the end of the decade. It’s also the engine that won’t be put in the Mustang just yet. And this is very unfortunately, because it has enormous power capabilities, light weight, and would be of enormous interest to Mustang enthusiasts. Perhaps too much… because owners would start their modifications on day 1 and the durability of this engine has yet to be demonstrated.
Ye old “modular” 4.6 and 5.4 liter engines are dead and buried for the F-150. They did the job that was expected of them, but after 20 years they weren’t going to go any further and were well behind the curve. Keep in mind that GM introduced several new generations of V-8 engine in that time (and will soon switch to an all-new 5.5 liter engine), Chrysler introduced the Hemi in 2 (soon to be 3) displacements, and Toyota and Nissan brought out new and very modern engines as well. Ford desparately needed to replace the old modulars, and they needed to do it 10 years ago.
And, nice to see that 6-speeds are standard ac ross the board. Now it’s time to start looking at 7- and 8-speeds. Chrysler is bringing an 8-speed to market next year for the 300C that will probably show up in their trucks as well, once manufacturing of it is moved from German to the U.S. in th enext few years.

ALL NEW FORD F-150 POWERTRAIN LINEUP DELIVERS BEST-IN-CLASS FUEL ECONOMY, POWER AND CAPABILITY
- The powertrain lineup for the 2011 Ford F-150 features four new truck engines: a 3.7-liter V6, 5.0-liter and 6.2-liter V8s, and a twin-turbocharged EcoBoost™ 3.5-liter
- Headlining the engine lineup is a new twin-turbo EcoBoost engine with Ti-VCT that has been specifically tuned, calibrated and tested for durability and reliability
- Each new engine delivers best-in-class towing and horsepower. The entire 2011 F-150 lineup will be at least 20 percent more fuel efficient than the 2010 F-150 lineup
- Ford is the first and only automaker to equip its entire full-size pickup lineup with fuel-saving six-speed automatic transmissions as standard equipment
DEARBORN, Mich., Aug. 11, 2010 – For the 2011 model year, the Ford F-150 is getting the most extensive powertrain overhaul in the truck’s history. The 2011 F-150 has four new truck engines, all coupled to a revised six-speed automatic transmission.
Each engine delivers improved fuel economy, outstanding performance and class-leading capability. This versatile new powertrain lineup enables F-150 customers to choose the engine that best suits their needs.
Available at launch are a 3.7-liter V6 and a 5.0-liter V8, each with fuel-saving and performance-enhancing twin independent variable camshaft timing (Ti-VCT) technology, and a version of the 6.2-liter V8 that is the base engine in the 2011 Ford F-Series Super Duty. A 3.5-liter EcoBoost engine, specially tuned and calibrated for the F-150, will be available in early 2011. Each of the engines offers an unequaled combination of attributes that matter most to F-150 customers: torque, horsepower, fuel economy, performance, durability, reliability and capability. The 2011 F-150 lineup will deliver best-in-class fuel economy. When the 3.5-liter EcoBoost engine joins the lineup, the 2011 F-150 will have up to 20 percent better fuel economy compared with the outgoing 2010 F-150.
“Our new engine lineup allows greater flexibility for customers to select the powertrain choice that best suits their needs,” said Barb Samardzich, vice president of Powertrain Engineering. “We are in the midst of a powertrain revolution, with 30 new powertrains over the next two years, and our loyal F-150 customers are the next ones to benefit.”
Extensive testing program to ensure truck application
To ensure the highest quality, most reliable engines, Ford engineers studied the warranty history of the outgoing engines and developed testing procedures based on the real-world driving experiences from current F-150 drivers.
Prototype engines underwent a wide range of tests to ensure complete compatibility with truck application and truck durability, with all components and systems passing testing to the equivalent of 150,000 miles. Components such as the exhaust manifolds and the crankshaft (forged steel) were upgraded, piston-cooling jets and oil coolers were added, and engines were specifically calibrated for improved heavy-duty operation and durability in F-150.
“Truck customers demand an engine that delivers outstanding low-speed torque to help tow or move heavy payloads, and sustained high-load, low-speed operation is a key attribute they look for,” said Samardzich. “The engine lineup for the 2011 Ford F-150 has been tuned specifically for truck operation needs and optimized for fuel economy. The result is a lineup that delivers class-leading towing and payload capability with outstanding horsepower, torque and fuel economy.”
Here are the highlights of each new engine:
3.7-liter four-valve Ti-VCT V6
The 3.7-liter will be the most powerful, capable and fuel-efficient base V6 of any truck in its class. Key attributes include:
- Best-in-class 300 horsepower (estimated) at 6,500 rpm
- 275 lb.-ft. of torque at 4,500 rpm
- Class-leading fuel economy
- Best-in-class 6,100 pounds maximum trailer tow
- Ti-VCT creates precise, variable timing control of both the intake and exhaust camshafts to optimize power, performance and fuel economy
- E85 flex fuel capability
- Piston-cooling jets, which squirt oil on the underside of the pistons to keep the piston crowns cool under extreme operating conditions
- Forged-steel crankshaft for improved durability
- Built at Cleveland Engine Plant
The 3.7-liter V6 powering the base 2011 F-150 is the latest application of the award-winning Duratec® V6 engine, with additional technology and upgrades for truck application. In particular, more work was done on the bottom end of the engine, a strong point of all Duratec V6 engines.
“This is a well-designed engine with a massive amount of attention to detail around the block and the structure of the block,” said Jim Mazuchowski, V6 engines program manager. “This attention to the stiffness and rigidity of the bottom end, how the engine is fastened with four-bolt mains and two side bolts, enhances durability and NVH (noise, vibration and harshness).”
Other enhancements for durability include a forged-steel crankshaft, cast-iron exhaust manifolds and a die-cast aluminum oil pan, which supports a 10,000-mile interval for oil changes. The design of the cylinder bore and piston rings has been optimized for efficient lubrication.
In addition to engine durability, Ti-VCT leads a host of technologies that increase overall engine efficiency. Ti-VCT’s precise and variable control of the intake and exhaust camshafts optimizes performance and fuel economy. The piston squirters enable faster engine warm-up, and the polished buckets reduce friction, which aids fuel economy.
5.0-liter four-valve dual-overhead-camshaft Ti-VCT V8
The 5.0-liter V8 in the 2011 F-150 offers many class bests compared with competitors’ entry-level V8s, including:
- Best-in-class 360 horsepower at 5,500 rpm and 380 lb.-ft. of torque at 4,250 rpm
- Class-leading fuel economy
- Best-in-class 9,800 pounds maximum trailer tow
- New strengthened block and new cylinder head optimized for performance and enhanced cooling
- Unique intake camshafts, combined with Ti-VCT, composite intake manifold and optimized compression ratio for improved low-speed torque and towing capability
- Forged-steel crank and all-new oil cooler enhance durability
- Piston-cooling jets, which squirt oil on the underside of the pistons to keep the piston crowns cool under extreme operating conditions
- E85 flex fuel capability
- Built at Essex Engine Plant; Windsor, Ontario
While this 5.0-liter V8 engine is similar to the one powering the 2011 Mustang GT, it has several important differences to optimize it for the harsh duty cycle truck customers demand. First, the camshafts were tuned to improve low-speed torque, which is key to truck customers. Also, the 10.5:1 compression ratio was optimized to reduce knock tendency at lower engine speeds while towing.
The hardware added to the 5.0 specifically for F-150 includes: an additional oil cooler, which helps extend the life of the oil to 10,000-mile intervals; foam covers for the fuel injectors to reduce NVH; and cast exhaust manifolds for improved durability. The new aluminum block is 70 pounds lighter than the 5.4-liter V8, which aids fuel economy and improves handling. The engine’s forged-steel crankshaft also ensures durability.
“This engine uses proven technology to deliver a great combination of low-speed torque and fuel economy with the durability F-150 customers demand,” said Mike Harrison, V8 engine programs manager.
6.2-liter two-valve single-overhead-camshaft V8
The 6.2-liter V8 is a premium engine offering on the 2011 F-150, with an expanded offering to F-150 SVT Raptor and other specialty applications. Its attributes include:
- Best-in-class 411 horsepower at 5,500 rpm and 434 lb.-ft. of torque at 4,500 rpm
- Best-in-class 11,300 pounds maximum trailer tow
- Competitive fuel economy
- Durability of race-proven components and technology showcased in November 2008 when a 6.2-liter Raptor R not only survived the grueling Baja 1000, it earned a podium finish. The same engine went on to complete every mile of the 2009 Best in the Desert series
- Utilizes a large bore and shorter stroke. This approach to creating power has its roots in storied Ford racing engines. The large bore allows for larger intake and exhaust valves for improved engine airflow, and the short stroke allows higher engine speed for increased horsepower
- Because of the large bore size, two spark plugs per cylinder are used to more efficiently burn the fuel-air mixture in the combustion chamber, enabling better fuel economy and increased engine torque. The twin plugs also help the engine maintain a smooth, stable idle
- Built at Romeo (Mich.) Engine Plant
The 6.2-liter V8, standard on the 2011 F-Series Super Duty, is uniquely tuned for the F-150 with a special cam profile. The engine will be standard on the 2011 F-150 SVT Raptor and other specialty applications, and pumps out up to 411 horsepower and 434 lb.-ft. of torque – making the F-150 the most powerful truck in its class.
“This engine has tons of torque, and already has been proved in the field with both the F-150 SVT Raptor and Super Duty,” said Harrison.
3.5-liter Ti-VCT EcoBoost
The 3.5-liter EcoBoost is a premium engine offering available after launch with power comparable to a naturally aspirated V8 and projected class-leading fuel economy. Its attributes include:
- Ti-VCT creates precise, variable timing control of both the intake and exhaust camshafts to optimize power, performance and fuel economy
- Fuel economy improves up to 20 percent versus 2010 model year F-150 5.4-liter V8
- Improved intake and exhaust camshafts optimized for improved fuel economy and performance
- Cast exhaust manifolds for heavy-duty operation and durability
- Improved manifold and cylinder heads for improved performance
- Direct-acting mechanical bucket (DAMB) valvetrain with polished buckets to reduce friction and improve fuel economy
- Built at Cleveland Engine Plant
Transmission features customer-driven enhancements
Ford Motor Company is the first and only manufacturer to equip its entire full-size pickup truck lineup with fuel-saving six-speed automatic transmissions as standard.
For the first time, a six-speed automatic transmission is standard in F-150 on all engines. Several available enhancements have been added to the proven 6R80 transmission to help F-150 customers tow more easily, including SelectShift with both progressive range select and manual functions.
Progressive range select allows the customer to reduce the range of available gears while in Drive. When the customer taps down into range select mode, the display shows the available gears and highlights the current gear state. This feature allows the driver to limit the use of upper gears when heavily loaded or while towing on grades.
With SelectShift, customers can get full manual function by pulling the shift lever into “M” for manual mode and then select the gear desired by pressing the “+” button for upshifts or the “-” button for downshifts. The control system will hold that gear for a full manual transmission feel.
The new engines for the Ford F-150 follow the all-new engine lineup for the 2011 Ford F-Series Super Duty introduced earlier this year and highlighted by the 6.7-liter Power Stroke® V8 turbocharged diesel, which delivers best-in-class torque, horsepower and fuel economy.
“The new powertrain lineup for the 2011 F-150 will provide a wide range of choices to customers to suit their needs, each tested for maximum durability and reliability with outstanding fuel economy,” said Samardzich.

2011 Mustang and F-150: Coyote V-8 origins?
Looking thru the specs of the new engine and the slightly revised car, we have to wonder where this engine came from. How could this company come up with an all-new engine given it’s terrible financial condition? Is the Coyote engine a considerably warmed over Modular engine, or is it a brand-new “clean sheet” design?
From the specs, we see a bore of 92.2mm (3.63″) and a stroke of 92.7mm (3.65″).
Compare this to a 4.6 Modular engine with 90.2mm and 90.0. The ridiculous 5.4 has the same bore and an ultra-long stroke of 105.8mm (4.17″). Hmmm, no Modular clue here.
What Ford hasn’t supplied is the bore-to-bore center measurement. If it’s the same as the Modular engine, then this is a reworked Modular – or at least the production equipment could be reused (saving considerable dollars). But Ford doesn’t supply this important figure.
There is a very small chance that this is a heavily reworked Lincoln LS engine – that engine is basically unrelated to the Modular (some believe that seed money and technology for it’s original development came from Ford before Ford purchased Jaguar), although it’s recently been reworked into a 5 liter displacement for Jaguar and Land Rover. The effort to buiild a 5 liter variant of it started when Ford still owned both, and of course the Lincoln LS variant of the Jaguar V-8 (offered in 3.5, 4, and 4.2 liter variations) was produced in Cleveland, Ohio. This is a much more modern engine than ye olde Modular, and offered the potential for much better breathing and ultimate performance. Not that it was ever developed very highly for street use (although Jaguar did have a well developed racing version).
And what’s relationship to the also-new 6.2 liter V-8? That engine has a much larger bore of 102mm and a stroke of 95mm. As was shown during the development program, displacement can go all the way up to 7 liters (a 7 liter DOHC performance engine was dropped from production plans a few years ago). Are these engines related? No way to tell from the specs that have been released, although we tend to doubt it. This engine has a long development history, cancelled twice and then restarted as Ford’s financial and market positions fluctuated. It was developed under the code-name Hurricane and then switched to BOSS when the political ramifications of Katrina were considered. It’s likely that it’s a somewhat older and separate design.
But until Ford releases the full set of specs, or enthusiasts get their hands on a 5 liter engine and take measurements, we won’t know for sure. Some people already have their hands on the 6.2. And Ford has several engine development partners who have traditionally done a lot of the basic engineering work on it’s engines – likely one or more of them was also involved (as examples, Roush helped with development of the Modular, and Porsche did some of the design work of the original Duratec 2/2.5/3 liter V-6) . We’ll have to keep an eye on supplier press releases for more information here.
More details emerge on the new Ford Boss V-8 engine
Nothing here for Driving Enthusiasts… this is nothing more than a truck engine. An enthusiast version, with an aluminum block and DOHC heads, was cancelled a long time ago. The age of giant engines is over… it will be about less cubic inches and more efficiency going forward.
Ford Press Release follows:
![An image named FRD2009092441814_PV[1].jpg](http://www.drivingenthusiast.net/sec-blog/images/2009/09/24/FRD2009092441814_PV[1].jpg)
- The 2011 Super Duty with the all-new Ford 6.2-liter V-8 engine will deliver significantly improved torque and horsepower as well as class-leading fuel economy; it can run on regular-grade gasoline, E85 or any blend in between
- Optimization of the engine
More information surfaces about the new Ford big-block 6.2 liter V-8
Code-named “Boss”, the all-new Ford 6.2 liter V-8 will be used in variations of the F-150 pickup and the related SUVs. It will not be used in the Mustang and was never planned for use in the Mustang. Instead, an aluminum 4-valve variation was to be used but that has been cancelled – the much smaller Coyote 5 liter is the only other new V-8 engine going forward and that is also primarily a truck engine.
The Boss was cancelled out-right at one point, but then resuscitated when the economy was in a false growth curve. Now it’s in a very strictly limited production engine, and the 4-valve and 7 liter variations of it have been killed and will never see the light of day. This, the 5-liter Coyote, and the EcoBoost V-6 will replace the existing 4.6 and 5.4 liter engines – which are seriously out-dated and scheduled for end-of-life soon.
Note that this is an iron-block engine. Clearly Ford’s lack of development funding shows here. It’s also a SOHC design, with 2 valves per cylinder. Exemplary breathing was never the plan here: it’s a low-rev high torque engine. It’s competitive to GM’s 6 liter truck engines, but is not at all competitive with their 6.2 liter performance variations. The engine was designed when engines of this size were thought to be in the long-term plan – now that has changed and it’s an open question how long this engine will survive. Even to the end of the decade is a stretch.
And note how the Raptor team devised a cooling test that might actually work. This will be the first SVT-labeled product that might actually survive tough cooling challenges. After a long series of SVT vehicles that couldn’t stay cool on racetracks, maybe they’ve finally “got it”.

AutoBlog scores the first pic of the Ford Boss 6.2 SOHC V-8 engine
AutoBlog (http://www.autoblog.com/2009/02/17/6-2l-boss-v8-found-under-hood-of-2010-ford-f-150-harley-davidson/) scored big time with the first confirmed image of the all-new Ford V-8 engine code named “Boss”. It’s a iron block 6.2 liter SOHC V-8. It’ll be found in future Ford big trucks, such as the SVT Raptor and F-150 – although money woes prevented it from being offered at the start of production of those vehicles. Another variant of this engine with 4 valves per cylinder was to be offered in the Mustang… but this has been canceled and the Mustang will rely on a heavily revised modular engine of 5 liters in size, along with the twin-turbo EcoBoost V-6.
Look closely and you can see this this is an engineering development platform and is not yet production ready (note the sticker on the air cleaner box, and various tape-wrapped wires). You can also see the very nice finned aluminum valve covers reading “Powered by Ford”.
What will become of the Ford BOSS big block?
The all-new Ford big block has been under development for several years now. At one point it was canceled, then later restarted. Earlier this summer, all work to put versions of it in the Mustang and F-150 was permanently canceled, with only use in the Super Duty a possibility going forward.
So it’s dead for Mustangs - leaving Ford out of the “big block” world. Instead, Ford will use a variant of the current 4.6 DOHC engine in 5 liter DOHC form in the re-skinned 2010 Mustang (or a year later, depending on corporate finances) and a version of the twin-turbo V-6 “EcoBoost” 3.5 liter DOHC V-6 (in 2010 or later, again depending).
The only picture ever published with permission of the dead big-block was in a Roush drag Mustang, in iron-block SOHC cam form:

However, some other pictures of this same iron-block SOHC engine made it out the doors:



Now that the engine is dead, will there a plan put in place to offer it for off-road Mustangs via the aftermarket? Speculation at this point, and given it’s weight and lack of factory support not particularly desirable. We think this is the end of this engine for the Mustang crowd…
Ford severely scales back the BOSS engine program
Automotive News reports today that Ford has severely scaled back the BOSS engine program. Only one vehicle will receive it – the F-250 (and up) series as a replacement for the 6.8 liter V-10 (which is therefore implied to be cancelled as well).
This means no BOSS engine in the mainstream F-150 or special editions Mustang.
The new F-150 (actually heavily reskinned – not all-new despite what the marketers want you to believe) will launch with variants of the existing 4.6 and 5.4 liter engines. Well after launch, the F-150 will also receive a 4.4 liter diesel, a 3.5 liter EcoBoost V-6, and eventually a larger variant of the naturally aspirated 3.5 liter V-6 engine. In terms of cubic inches, this will leave it at a disadvantage to the competitors from GM and Chrysler – however better mileage will be available as well as a wider range of engine options. That’s clearly what is needed in today’s market and for the market going forward… versus the market 4-5 years ago when the F-150 revisions were first determined.
This also leaves the Mustang without a “big-block” engine. While it hasn’t been seen in public yet, it’s believed that an evolution of the 4.6 liter engine will be offered in 5 liter displacement. Just exactly how much money went into that evolution is under intense debate on the web… with self-proclamined experts arguing over whether it will have 3 or 4-valve heads, and how much power they can dream up. This engine will also apparently find it’s way into the F-150 as well. And further developments of it are believed to be planned to replace the long-stroke (and highly inefficient) 5.4 liter engine. In any case it’s already known that the 3.5 liter EcoBoost V-6 will be offered in the Mustang and performance enhancements to that may be possible.
And, just as Chevy is considering their boosted 2 liter 4-cylinder engine for the Camaro (260 HP, 260 torque), Ford has an EcoBoost 2 liter 4-cylinder (275 HP, unknown torque) in the pipeline that would work just as well. These 2 engines are producing torque that the previous 4 cylinder Mustang never produced and would provide an satisfying driving experience with the right transmission and gearing.
Ford 2009 BOSS V-8 engine discussion
Lots of discussion going on over at the Blue Oval News Ford forums on the upcoming large displacement Ford “BOSS” V-8 engine. The engine will be used first in the updated 2009 Ford F-150 pickup truck, then later on in a different form in an updated Mustang (2010?).
Note that the discussions on the board are all unconfirmed rumor at this point – nothing has been announced other than the codename of BOSS.
But there are some good sources on the board ;-)
New Blog on our site: 2010 Ford Boss Engine
Well, not new, as I’ve been blogging about the 2010 Ford BOSS V-8 engine (previously code named Hurricane) since December 2004.
This on-again and off-again project is finally ON as part of the Ford Way Forward plan.
Not much is officially known about this engine: the brand name is BOSS, it will debut shortly after the debut of the 2009 F-150, and it will also be used in the redesigned Mustang (~2010). References are already being made to it in the 2009 F-150 program by Ford, as well as by suppliers.
Unofficially, this appears to be both the truck and the performance V-8 going forward. The modular engine is IMHO old, tired, and already extended past viability in 5.4 liter form. I suspect we’ll continue to see 4.6 and 5.0 liter variants… and that the 5.4 in trucks will be replaced by the BOSS 5.8. Performance variants will be 6.2 liters in displacement.
In any case, as we see more information on the 2009 F-150 (perhaps a concept in April at the New York show??) we will learn more about this engine. I’m looking forward to seeing some in-depth architectural discussion and imagery of it.
