in 1990 for the 1991 model year. The term “modular” applied to the setup of tooling and casting stations in the Windsor and Romeo engine manufacturing plants, not the engine itself.
The Modular engine family started with the 4.6 L in 1990 for the 1991 model year. The Modular engines are used in various Ford,
Lincoln, and
Mercury vehicles. Modular engines used in Ford trucks were marketed under the Triton name from 1997–2010 while the InTech name was used for a time at Lincoln and Mercury for vehicles equipped with
DOHC versions of the engines. The engines were first produced at the
Ford Romeo Engine Plant, then additional capacity was added at the Windsor Engine Plant in
Windsor, Ontario

Origins
In the early 1980s, then-Ford Motor Company chief operating officer
Donald Petersen challenged Ford's vice-president of design,
Jack Telnack, and his staff to come up with new vehicle designs to replace the boxy styling that had dominated Ford products for years. The result was the adoption of sleeker, more aerodynamic designs like that used for the highly successful
Ford Taurus. In the second half of the 1980s, Petersen, then chief executive officer, sought to update Ford's decades-old V8 architectures, challenging Ford senior engineer Jim Clarke to develop a new V8 engine that would surpass Ford's earlier V8s in every meaningful way, from power and efficiency to emissions performance and smoothness of operation.
Clarke and his engineers studied engine designs from major European and Japanese automakers and sought to develop a technologically advanced, power-dense, dependable, low maintenance V8, with no major service required before of use.
The initial engine design would implement a 90° vee-angle with a bore and a stroke of , resulting in a
displacement

and creating a nearly 1:1
bore-to-stroke ratio. This square configuration was chosen primarily for its positive
noise, vibration, and harshness characteristics. The engine would utilize features such as a chain-driven,
single-overhead camshaft valve train with
roller finger followers, a deep-skirt cast-iron
block construction and
cross-bolted main bearings, all benefiting long-term durability. In the interest of reducing overall engine weight, aluminum-alloy
heads would be standard and all major engine accessories would be mounted directly to the block, resulting in a more complex block casting but eliminating the need for heavy mounting brackets. All engines in the family shared a common bore spacing of .
Tight construction tolerances were used in shaping cylinder bores to accommodate narrow
piston rings. This improved engine efficiency through reduced friction and oil consumption while also promoting cleaner
emissions.
Various single- or dual-overhead camshaft eight- and ten-cylinder engines could be produced. Six-cylinder derivatives were also explored, though never built. In order to accommodate the wide array of engine configurations possible within this architecture, Ford developed a new modular tooling system for producing different engines quickly and efficiently in the same factory.
Such an approach allowed for significantly faster changeovers when switching from one engine platform to another among the modular engine family. This also allowed for the existing engine plants, and their supporting offsite production facilities, to handle shorter production runs.
By 1987 Ford was fully committed to producing the new Modular V8,
having invested $4 billion (~$ in ) in the engine's design in addition to retooling the company's
Romeo, Michigan tractor plant to build the engines. Three years later, in the third quarter of 1990, the first Modular engine, a 4.6 L SOHC V8, would be used in the 1991 model year
Lincoln Town Car. In spite of having a smaller displacement, the lighter 4.6 L Modular V8 could generate more power than the Town Car's previous
overhead valve 5.0 L V8 and accelerate to 1.5 seconds faster, all while delivering better fuel efficiency.
Ford modular engines would go on to become its chief gasoline V8s and V10s.

The first production Modular engine was the 4.6 L 2-valve
SOHC V8 introduced in the 1991
Lincoln Town Car.
The 4.6 L 2V was built at both Romeo Engine Plant and Windsor Engine Plant, which had different designs for cylinder heads (cam caps: interconnected cam "cages" vs. individual caps per cam journal), camshaft sprockets (bolt-on vs. press-on), valve covers (11 bolts vs. 13 bolts), crankshaft (6 bolts vs. 8 bolts) and main bearing caps (2 bolt fasteners with 2 jack screws vs. 2 bolt fasteners with dowel pins).

The 3-valve
SOHC 4.6 L with
variable camshaft timing (VCT) first appeared in the redesigned 2005 Ford Mustang.
The engines are equipped with an electronic
Charge Motion Control Valve (CMCV) system that provides increased air velocity at low engine speeds for improved emissions and low-rpm torque. Cylinder block material varies between aluminum used in the 2005-10 Mustang GT and cast iron used in the truck applications.
The 3-valve SOHC 4.6 L engine was on the

4-valve

The 4-valve
DOHC version of the Modular engine was introduced in the 1993
Lincoln Mark VIII as the 4.6 L ''Four-Cam'' V8. Lincoln marketed the engine under the name ''InTech'' after 1995.
The 1993–1998 4-valve engines featured cylinder heads with two intake ports per cylinder (split-port) and variable runner length intake manifolds with either vacuum or electrically activated intake manifold runner controls (IMRC) depending on application. The engine was revised for 1999 with new cylinder heads featuring tumble-style intake ports (one intake port feeding two intake valves), new camshaft profiles, and fixed runner-length
intake manifolds. These changes resulted in more power, torque and a broader power-band when compared to the earlier 4-valve engines.
All 4.6 L 4-valve engines featured aluminum engine blocks with 6-bolt main bearing caps, the only exception being the 2003–2004 SVT Cobra which had a 4-bolt main cast iron block. The 1999 and earlier engines featured an aluminum block cast in Italy by

5.0 L Coyote

The Coyote V8 was first produced in 2010 for the 2011 model year. It was an evolutionary development of Ford's Modular V8, and is assembled in Ford's Essex Engine Plant in Windsor, Ontario, using existing Modular tooling.
Ford engineers needed to design a V8, specifically for the Mustang GT, that would compete with the
GM 6.2 L LS3 used in the new
Chevrolet Camaro, and the new
Chrysler 6.4 L HEMI in the
Dodge Charger,
Dodge Challenger,
Chrysler 300 and
Jeep Grand Cherokee. Since this engine replaced the already popular 4.6 L and 5.4 L Modular Engines, this engine had to remain close to the same physical size of the outgoing 4.6 L, and share other specifications with it such as bore spacing, deck height, bell housing bolt pattern, etc. in order for the engine to utilize existing Modular production line tooling (the source of the 'Modular' designation for the engine family). The result was the 5.0 L Coyote, which produced roughly the same amount of power as its competitors, but with a much smaller displacement.
It shares the 's bore spacing and deck height, while bore diameter and stroke have increased to , respectively. The engine also retains the 4.6 L's connecting rod length, which produces a 1.62:1 rod to stroke ratio.
[5.0 Mustang & Super Fords (March 2010) "Coyote Beautiful"] The firing order has been changed from that shared by all previous Modular V8s (1-3-7-2-6-5-4-8) to that of the
Ford Flathead V8 (1-5-4-8-6-3-7-2).
Compression ratio is 11.0:1, and despite having port fuel injection (as opposed to
direct injection) the engine can still be run on 87 octane gasoline.
The Coyote features all new
4 valve DOHC cylinder heads that have shifted the camshafts outboard, which allowed for a compact roller finger follower setup with remote hydraulic valve lash adjusters and improved (raised) intake port geometry. The result is an intake port that outflows the Ford GT intake port by 4 percent and the Yates D3 (NASCAR) intake port up to lift, which is the maximum lift of the Coyote's intake cams. Engine redline is 7000 rpm.
The Coyote is Ford's first implementation of its cam-torque-actuated (CTA)
Twin Independent Variable Cam Timing (Ti-VCT) in a V8 engine, which allows the powertrain control module (PCM) to advance and retard intake and exhaust cam timing independently of each other, providing improved power, fuel economy and reduced emissions.
To strengthen the block enough to handle increased output, webbing was extensively used as reinforcement in the casting, rather than increasing the thickness of the walls. The intake plenum was also situated low between the two cylinder banks to meet the height constraint, thus the alternator traditionally placed low and center was moved to the side of the engine.
The Coyote made
Ward's 10 Best Engines list for 2011, 2012, and 2018.
Boss 302 (Road Runner) variant
A higher performance variant of the Coyote, dubbed Road Runner internally by Ford, is produced under the Boss 302 moniker used for the resurrected Boss 302 Mustang for the 2012 model year.
The Boss 302 receives CNC ported heads cast in 356 aluminum providing additional airflow and strength, and a higher lift exhaust camshaft profile is used. Valvetrain components were lightened as much as possible, including the use of sodium filled exhaust valves, while strengthened powdered metal rods and forged aluminum pistons were added. Piston-cooling jets were also deleted, which are standard in the 5.0 model.
Exterior changes include a high-mount intake plenum (as opposed to the standard engine's low-mounted one) with shorter runners to improve high-rpm power. Power is increased from to , and torque drops from to due to the upgrades. The Boss's redline is increased to 7500 rpm, but has been verified stable up to 8400.
Gen 3 update
For 2018, Ford made revisions to the Coyote equipped in the
Mustang GT, most notably the addition of high-pressure
direct injection (in addition to the existing
port injection system), and an increase of the piston bore diameter from . This increase in the bore size, resulting from the adoption of
Plasma Wire Arc Transfer cylinder liner technology in place of the more traditional
sleeve in the block, brings total displacement up from . Other changes include Gen. 3 specific camshafts, enlarged intake and exhaust valves, an increased compression ratio of 12.0:1, a revised intake manifold, and 7500 rpm redline in the Mustang. With these changes the updated 5.0 L Coyote is rated by Ford at and . The 2019–2020 Bullitt and 2021–2023 Mach 1 models received an uprated version of the Coyote rated at and . The improvement was due to an intake manifold and 87 mm throttle body borrowed from the 5.2 L Voodoo engine as well as a recalibrated powertrain control module.
Gen 4 update
In 2023, for the 2024 model year, the
Mustang debuted with the 4th generation of the Coyote engine. It produces and in the GT trim level, and with the Active Performance Exhaust option, and and in the Dark Horse trim level. Updates include:
* Revised 4 into 1 exhaust manifold
* Intake manifold with dual 80 mm throttle bodies
The Dark Horse also received:
* Revised camshafts
* Forged piston rods from the 5.2 L Predator engine
F-150 variant
A torque-biased variant of the Coyote is produced as an alternative to the EcoBoost V6 in the F-150 pickup truck. The F-150 5.0 L receives a lower compression ratio (10.5:1), intake camshafts with less duration, cast iron exhaust manifolds, and revised cylinder heads to improve cooling. The intake manifold changed only in color, and height. These changes promote low-end and mid-range power and torque. The engine retains the Coyote's forged steel crank and piston-cooling jets but benefits from the addition of an external engine oil cooler similar to the Boss 302's. The changes result in the engine's peak horsepower dropping to at 5500 rpm, while torque is rated at at 4250 rpm. When the 2015 F-150 was revealed, Ford improved the induction system to pull air from above the grille under the hood (aka Ram Air Effect) as opposed to the fender intake inlet that had been used for all previous Ford Modular Engines. The addition of Ram Air Effect pulled more cool air into the engine in favor for a power increase to at 5750 rpm and at 3850 rpm.
For 2018, numerous revisions were made to the 5.0. Most notably, the adoption of a port and direct fuel injection system, as well as spray-on bore liner, eliminating the need for conventional cast iron cylinder bore liners (changes shared with the 2018 Mustang), and compression ratio is increased to 12.0:1. Power increased to at 5750 rpm, while torque is rated at at 4500 rpm.

Applications
The engine is gradually replacing the 4.6 L and 5.4 L Modular V8 units in all Ford vehicles. This is the first time that Ford has used the "5.0" designation since the
pushrod 5.0 was discontinued and replaced by the 4.6 L Modular unit in the mid-90s.

Voodoo
The "Voodoo" is a development of the Coyote engine. The engine was developed specifically for the
Shelby GT350 version of the
sixth generation Mustang. Bore and stroke are both up from the 5.0 L Coyote at , as is the compression ratio at 12.0:1. The Voodoo makes at 7500 rpm and of torque at 4750 rpm and has a redline of 8250 rpm. In 2016, the engine received a
Ward's 10 Best Engines award. Like other modern
Ford Performance Mustang engines, the Voodoo is hand-built at Ford's
Romeo Plant on the Niche Line.
Unlike the Coyote and previous Modular V8s, the Voodoo features a
flat plane crankshaft. During development, Ford purchased a
Ferrari California, the only other front-engine flat-plane crank V8 car in production at the time, as a benchmark. The Voodoo features a unique Up-Down-Up-Down
crank pin configuration, as opposed to the typical Up-Down-Down-Up in inline-4s and other flat-plane V8s. Due to the unique crankpin configuration, the back-to-front firing order of 1-5-4-8-3-7-2-6, is also unique to the Voodoo. This engine was the biggest production flat plane crank V8 by displacement until

Based on the Predator engine, the engine used in the 2023 F-150 Raptor R is tuned for more low-end torque by using a different supercharger pulley and a new calibration. It is produced on a new Niche Engine line at the Dearborn Engine Plant.
5.4 L
The V8 is a member of the Modular engine family first introduced in the 1997 F-series pick-ups, in place of the 5.8 L 351W. Bore diameter is and stroke is , the increased stroke necessitated a taller engine block deck height. A connecting rod length is used to achieve a 1.60:1 rod to stroke ratio. The 5.4 L 2V was built at the Windsor Engine Plant, while the 5.4 L 3V moved production to the Essex Engine Plant beginning in 2003, then back to Windsor Engine Plant in 2009. The SVT 5.4 L 4-valve engines are built at Romeo Engine Plant, hand assembled on the niche line.

The SVT Cobra R version of the 5.4 L 4-valve V8 had several key differences from its Lincoln counterpart. While the iron block and forged steel crankshaft were sourced directly from the InTech 5.4 L, the Cobra R powerplant benefited from new, high-flow cylinder heads that were designed with features developed for Ford's "Rough Rider" off-road racing program, application specific camshafts with higher lift and more duration than other 4-valve Modular cams, forged I-beam connecting rods sourced from Carillo, forged pistons that provided a 9.6:1 compression ratio in conjunction with the 52 cc combustion chambers, and a unique high-flow "cross-ram" style aluminum intake manifold. The Cobra R was rated at and though chassis dynamometer results have shown these ratings to be conservative with unmodified Cobra Rs often producing nearly at the rear wheels.

The Shelby GT500 uses a 4-valve DOHC 5.4 L with an Eaton M122H Roots type supercharger and air-to-liquid intercooler. The GT500 5.4 L shares its high-flow cylinder head castings with the Ford GT, with only minor machining differences, and shares camshafts with the 2003–2004 Ford Mustang SVT Cobra; which have less lift and duration than the Ford GT camshafts. The 2007–2010 GT500 engine used an iron engine block, while the 2011 GT500 5.4 L receives a new aluminum engine block, with Ford's first production application of their patented Plasma Transferred Wire Arc (PTWA) cylinder coating, eliminating the need for pressed in cylinder liners. The PTWA spray apparatus was co-developed by Ford and Flame-Spray Industries of Long Island, New York, for which they received the 2009 IPO National Inventors of the Year Award. The 2011 GT500 engine weighs less than the previous iron-block version, thanks in part to the lack of cast iron cylinder liners. All of the 5.4 L 4-valve engines destined for use in SVT vehicles, such as the Ford GT and Shelby GT500, have been hand-built by technicians at Ford's Romeo, Michigan plant.

5.0 L and 5.3 L Cammer
In 2005, Ford Racing Performance Parts introduced a V8 crate engine for use in motor racing and home-made performance cars, officially called M-6007-T50EA, but more widely known as "Cammer". Since then, other higher performance variations of the Cammer have been introduced for KONI Sports Car Challenge and GT4 European Cup. All versions of the Cammer are DOHC 4-valve per cylinder designs with a bore and stroke of . The Cammer achieves its larger bore by resleeving the 4.6 L aluminum block.
The T50 Cammer crate engine, the least expensive and most street oriented version, uses derivatives of the cylinder heads, variable runner-length magnesium intake manifold, and camshafts first used in the 2000 FR500 Mustang concept car. These parts are unique to the T50 Cammer crate engine and are not found in any other production Modular applications. The T50 has an 11.0:1 compression ratio and exceeds with the proper exhaust manifolds.

Intake manifold defect
Starting in 1996, Ford began installing a DuPont Zytel nylon-composite intake manifold onto the 2-valve SOHC engines. Plaintiffs in class action lawsuits alleged that the coolant crossover passage of these intake manifolds may crack, resulting in coolant leakage. A US class-action suit was filed on behalf of owners, resulting in a settlement announced on December 17, 2005.
Starting with the 2002 model year, and implemented halfway through the 2001 lineup, Ford began using a revised DuPont Zytel nylon-composite intake manifold with an aluminum front coolant crossover that corrected the issue. Replacement intakes were also made available for 1996–2001 engines. To be eligible for reimbursement, owners needed to contact a Ford, Lincoln or Mercury dealer within 90 days of December 16, 2005. Further, Ford offered an extended warranty for this part, for seven years from the start date (which means the initial vehicle sale date) without a mileage limitation.
The following vehicles were included in this class-action suit settlement:
* Mercury Grand Marquis, 1996–2001
* Lincoln Town Car, 1996–2001
* Ford Crown Victoria, 1996–2001

Spark plug issues
2-valve 4.6 L, 5.4 L, and 6.8 L engines found in many 1997–2008 Ford, Lincoln, and Mercury vehicles may have aluminum cylinder heads with threads for spark plugs that are stripped, missing, or otherwise insufficiently bored out. Ford acknowledges this issue in Technical Service Bulletin

07-21-2 as well as earlier TSBs. Ford's TSB does not state that this issue is caused by owner neglect. For vehicles under the New Vehicle Limited Warranty, Ford will only cover the replacement of the entire cylinder head; however, the Ford recommended spark plug service interval extends beyond the duration of the New Vehicle Limited Warranty. Ford's only authorized repair procedure for out-of-warranty vehicles is to use the LOCK-N-STITCH aluminum insert and tool kit.
3-valve 5.4 L and 6.8 L engines built before 10/9/07 and 3-valve 4.6 Ls built before 11/30/07 found in many 2004–2008 Ford, Lincoln, and Mercury vehicles have an issue with difficult-to-remove spark plugs, which can cause part of the spark plug to become seized in the cylinder head. The source of the problem is a unique plug design that uses a 2-piece shell, which often separates, leaving the lower portion of the spark plug stuck deep in the engine's cylinder head. The 2-piece OE spark plug design is intrinsically flawed, thus making it susceptible to this problem. Ford acknowledges this issue in TSB 08-7-6 as well as earlier TSBs. Ford's TSB does not state that this issue is caused by owner neglect. The TSB provides a special procedure for spark plug removal on these engines. For situations in which the spark plug has partially broken off in the cylinder head, Ford distributes multiple special tools for removing the seized portion of the plug. Their TSB explains the multiple procedures required for handling the different cases/situations that occur when parts of plugs are seized in these engines. This repair is covered for vehicles under warranty; however, the Ford recommended spark plug service interval extends beyond the duration of the New Vehicle Limited Warranty.[Ford TSB 08-7-6]
