3.5 EcoBoost vs 5.0 Coyote #1 – Price & Running Cost
One of the main differences between these engines is the cost. Even though the EcoBoost has two fewer cylinders and has a smaller displacement, the 3.5 EcoBoost V6 variant of the Ford F-150 is still the more expensive engine. Even though there are several advantages to buying the 3.5, the price was a huge factor for people opting for the tried and tested V8.
There is a significant difference between the price of these engines, and even in the second-hand market, you can get an F-150 with the 5.0 V8 for cheaper in comparison to the 3.5 V6. The fact that there are multiple variants of the F150 that use the 3.5-liter engine, but far more people are more inclined towards the old-school V8 that is loved by everyone.
3.5 EcoBoost vs 5.0 Coyote #2 – Performance & Towing Capacity
There wasn’t a huge power difference between these two engines when their respective first-generation engines came out, but over the decade, these engines have been refined and upgraded to produce more power and be more efficient on the road. The 3.5-liter EcoBoost (second-generation High Output variant) is capable of producing more power and torque than the 5.0 V8.
The 3.5 is available in multiple variants of the F150, which produce about 450 horsepower and 510 LB/FT of torque. On the other hand, the 5.0 produces 395 horses and 400 LB/FT of torque. In fact, the twin-turbocharged V6 EcoBoost has a higher towing capacity than the naturally aspirated V8; around 14,000lbs compared to 13,000lbs. If you need to tow, get the 3.5 EcoBoost.
3.5 EcoBoost vs 5.0 Coyote #3 – Fuel Economy (MPG)
Despite producing more power, the 3.5-liter EcoBoost V6 also gives amazing gas mileage. The 3.5 EcoBoost gives a gas mileage of 18 MPG in the city and 23 MPG on the highway. On the other hand, the 5.0-liter V8 Coyote gives a gas mileage of 17 MPG in the city and 22 MPG on the highway. Not a huge variation, but enough to make a difference.
On top of that, the 3.5 EcoBoost V6 engine does have some interesting fuel-saving tech, giving the 3.5 EcoBoost an edge over the 5.0 Coyote. This is mostly thanks to the 3.5 EcoBoost’s clever engineering and design, as Ford relies on its turbocharging system to crank out more power, but remain hugely fuel efficient. You could even get a hybrid with the F-150, but in PowerBoost form.
3.5 EcoBoost vs 5.0 Coyote #4 – Reliability & Common Issues
Ford’s cars and engines are generally pretty reliable and dependable, which bodes well for owners in the long term. The EcoBoost V6 is no exception. The aforementioned 3.5-liter powertrain has been around for a decade, and no major red flags have been noted about this engine. Still, when compared to the naturally aspirated 5.0 Coyote V8, the 3.5 has more moving parts.
This alone makes it more likely to have a bad part and might cause problems. The most common issues with the 3.5 EcoBoost V6 on the F-150 are the carbon build-up on the intake valves, as well as timing chain failures. However, recent updates that were made to the later 3.5 EcoBoost V6 engines have mostly mitigated and solved these two problems for most people.
There are still other problems to be wary of with the 3.5 EcoBoost V6, such as cam phaser rattle, excessive spark plug & ignition coil wear, intercooler condensation, turbocharger failures, and more. Meanwhile, the generally more reliable 5.0 Coyote V8 isn’t invincible either, as it too can suffer from issues such as throttle body failures, cracked exhaust manifolds, water pump failure, spark plug ejection, and more.
3.5 EcoBoost vs 5.0 Coyote #5 – Maintenance & Servicing
The V8 engine has been a part of the F150 lineup since the 1950s. It is way less complicated to work on the 5.0-liter Coyote engine rather than a 3.5-liter EcoBoost. The V8 is one of the most common engines that are available in the United States. As such, any part of this engine can be easily replaced because of its wide availability.
Along with that, the V8 is such a common engine that any problem can be solved at a cheap price. So practically, it is easier to maintain a V8. Otherwise, servicing and maintaining a 3.5-liter EcoBoost requires that you need to work your way around the twin-turbocharger, countless electronics, and more, which makes it harder to service or maintain DIY.
3.5 EcoBoost vs 5.0 Coyote #6 – Technology & Features
When delving into the world of engines, advancements in technology can’t be overlooked. The 3.5-liter EcoBoost, with its twin-turbocharged setup, gives users an extra edge when it comes to immediate power delivery. The turbochargers ensure that there’s minimal turbo lag, resulting in prompt throttle responses.
This makes it especially effective in situations that require quick bursts of speed or rapid acceleration. On the contrary, the 5.0 Coyote V8 relies on natural aspiration, providing a more linear power delivery curve. Although it doesn’t have the sharpness of the twin-turbo setup, many drivers appreciate the predictability and smoother power progression that the V8 offers.
Moreover, the V8 has variable camshaft timing, optimizing performance across a broad power band. The choice becomes a matter of personal preference; do you lean towards modern tech or traditional raw power? Either way, you really can’t go wrong with just how much engineering Ford put toward either engine.
3.5 EcoBoost vs 5.0 Coyote #7 – Sound Profile & Exhaust Note
For many automotive enthusiasts, the roar of an engine can make or break their driving experience. The 5.0 Coyote V8 boasts that classic, throaty rumble that’s been a staple of American trucks and muscle cars. For those who enjoy an unmistakable growl under the hood, the V8 becomes an obvious choice.
In contrast, the 3.5 EcoBoost V6 has a different sonic profile. While it lacks the deep bass of the V8, it does offer a more refined, modern sound that’s characterized by the whine of the turbos. For some, this provides a futuristic touch, signaling the melding of performance with technological evolution.
3.5 EcoBoost vs 5.0 Coyote #8 – Environmental Considerations
Emissions and environmental considerations have become significant concerns for car owners and automakers. While both engines adhere to necessary regulations, the 3.5-liter EcoBoost, with its smaller displacement and advanced tech, generally emits fewer greenhouse gases than its V8 counterpart. This is crucial for those who prioritize eco-friendly choices in their vehicles.
Furthermore, the direct fuel injection in the EcoBoost can lead to a more complete combustion process, further minimizing pollutants. While the V8 offers an undeniably robust performance, those looking for a greener alternative might lean toward the V6.
3.5 EcoBoost vs 5.0 Coyote #9 – Resale Value
Resale value can be a defining factor for many potential buyers. Historically, vehicles fitted with V8 engines have maintained a slightly better resale value, mainly due to their widespread appeal and the romanticism attached to V8s in the American psyche. Plus, for long-term dependability and robustness, the Coyote V8 is less problem-prone than the EcoBoost V6.
However, as times change and technology evolves, the 3.5-liter EcoBoost’s reputation has been on the rise. Increasingly, users appreciate the blend of power and efficiency it offers, which could potentially increase its resale value in the coming years.

On the other hand, the 3.5 EcoBoost, given its relatively newer introduction and technologically complex setup, doesn’t have as extensive a range of aftermarket options. However, the ones that do exist, like performance tuners, are designed to squeeze out more power and efficiency from the engine.
The choice here boils down to tradition vs. technology: do you prefer customization with a rich history or the cutting-edge possibilities of a newer engine?
3.5 EcoBoost vs 5.0 Coyote #12 – Warm-Up & Cool-Down
Given the turbocharged nature of the 3.5 EcoBoost, it’s generally advisable for users to allow a short warm-up period before driving aggressively, and similarly, a brief cool-down period post-driving. This ensures the turbochargers and engine components experience less wear and prolong their lifespan.
In contrast, the naturally aspirated 5.0 Coyote V8 is less finicky about warm-ups and cool-downs. Although it’s always good practice to warm up any engine before hard driving, the V8 isn’t as demanding in this aspect. This goes to show where the 3.5 EcoBoost and the 5.0 Coyote engines, respectively bring distinct attributes to the table.
Fuel Costs And Economy
No doubt, one of the key deciding factors for many folks, when you’re comparing between the 3.5 EcoBoost vs the 5.0 Coyote, is their fuel economy. We’ve briefly touched on their mileage earlier, which is timely given ever fluctuating gas prices. Just so we remember, here’s a quick comparison of their EPA-estimated fuel economy:
- 3.5L EcoBoost V6 – 18 MPG city / 24 MPG highway
- 5.0L Coyote V8 – 17 MPG city / 24 MPG highway
At first glance, both engines have the same highway fuel economy figures. However, the 3.5 EcoBoost performs slightly better in the city, which can lead to noticeable fuel savings over time. This is especially so for those who do a lot of stop-and-go driving. And, they make a noticeable impact when you try to compare and estimate your annual fuel costs.
To estimate the difference, let’s assume:
- The average U.S. driver covers around 15,000 miles per year.
- Gasoline currently costs $3.50 per gallon (subject to change).
When we do some quick maths, here’s how each engine compares:
| Engine | City Driving (50%) | Highway Driving (50%) | Total Gallons Used | Estimated Annual Cost |
|---|---|---|---|---|
| 3.5L EcoBoost V6 | (7,500 ÷ 18) = 417 gal | (7,500 ÷ 24) = 313 gal | 730 gallons | $2,555 |
| 5.0L Coyote V8 | (7,500 ÷ 17) = 441 gal | (7,500 ÷ 24) = 313 gal | 754 gallons | $2,639 |
In short, the 3.5 EcoBoost V6 engine could save you around ~$84 in fuel costs yearly. That’s not a big difference, but it adds up over multiple years, especially for high-mileage drivers or fleet owners. Granted, if you mainly drive on the highway, fuel costs will be nearly identical between both engines.
Ownership Experience And Longevity
Aside from fuel economy, no doubt choosing between the 3.5 EcoBoost vs the 5.0 Coyote also comes down to long-term reliability. From a lot of past and present F-150 owners, it’s a key concern for many people. While we’ve found that both engines are well-engineered, their durability and maintenance experiences can differ from owner to owner.
For context, both the 3.5 EcoBoost and 5.0 Coyote engines can last well beyond 200,000 miles with proper maintenance. Their individual reliability, however, may vary:
- 3.5L EcoBoost V6 – With twin turbochargers and direct injection, this engine requires regular turbo maintenance and high-quality oil to prevent carbon buildup. Many owners report reaching 150,000–200,000 miles before major repairs, but turbo replacements ($1,500–$2,500) may be needed earlier.
- 5.0L Coyote V8 – This naturally aspirated V8 is known for its simpler design and fewer failure points. Many trucks with this engine exceed 250,000 miles with basic upkeep. The timing chain might see issues arising around 150,000 miles. Overall, though, the Coyote V8 is seen as more robust for high-mileage use.
| Engine | Common Reliability Issues | Estimated Repair Cost |
|---|---|---|
| 3.5L EcoBoost V6 | Turbocharger failure, carbon buildup, and timing chain stretch | $1,500 – $4,000 |
| 5.0L Coyote V8 | Timing chain rattle, cam phaser failure, and heavy oil consumption | $1,200 – $3,500 |
3.5 EcoBoost Pros And Cons
For many years, the pickup truck segment has been changing drastically. They want to introduce lighter, more powerful, stronger, and more efficient trucks in all key areas. The F150 has been able to dominate this market for a very long time, and any Ford enthusiast would never change their Ford with a Chevy or a Dodge.
When Ford introduced the 3.5-liter EcoBoost, the enthusiasts were a little skeptical, but after about a decade in the market, the EcoBoost engine performed better than expected, even compared to the popular 5.0 Coyote V8. Even though the EcoBoost, like every other engine, has its pros and cons, the engine has surprised everyone.
3.5 EcoBoost Pros
- Just like the 5.0 V8, the Ecoboost almost produces the same amount of horsepower and torque while giving better fuel economy in a half-a-ton pickup.
- People who buy the F150 for off-road purposes, work, and towing purposes are very happy with their F150 because of the low RPM torque.
- The EcoBoost engine is relatively quiet due to a V6 engine under the hood.
- The twin-turbo system is a very good option for someone who likes the instant acceleration and sound of a turbo.
3.5 EcoBoost Cons
- The downfall of the 3.5 EcoBoost is that it has to rely upon forced induction to create most of its power. A problem with the turbos can cause a huge power drop while driving the truck.
- The EcoBoost uses extra components that go through wear and tear over time. This causes more maintenance for owners down the road.
- For purists, the raw sound of the V8 will not be present.
- The 3.5 EcoBoost V6 is more expensive than the 5.0 Coyote V8 engine.
- Excess carbon build-up on the 3.5 EcoBoost is a common problem faced by the owners. It may cause power loss and misfires. The newer iterations have fixed this, but older ones still suffer from carbon build-up issues.
5.0 Coyote Pros And Cons
Folks have traditionally accustomed themselves to having a big torquey V8 under the hood of their Ford truck since the early 1950s. As the F150 evolved, so did the V8 that came with it. The V8 has had its fair share of triumphs and downfalls. The Coyote isn’t an exception. Here is a list of pros and cons that will help you make your decision about the 5.0 Coyote V8 vs the 3.5 EcoBoost V6.
5.0 Coyote Pros
- Unlike the EcoBoost, the Coyote engine uses all-American muscle and modern engine technology to create power and torque in a naturally aspirated capacity.
- The owner has to worry about fewer parts that can go bad, and the Coyote is an engine familiar to most mechanics and technicians, which makes maintenance easy and cheaper.
- The experience of raw power and torque that goes well with a big American V8 is always a net positive.
5.0 Coyote Cons
- Tunability is an issue to a certain degree, and it remains somewhat limiting. It depends on what you are planning to do with your F150.
- From the factory, the 5.0 Coyote creates significant amount of less torque than the EcoBoost does, therefore it cannot tow or haul as much.
- The EcoBoost has better fuel economy and efficiency than the 5.0 Coyote V8.
The redesigned 3.5L Ecoboost’s are said to be free from the carbon on the valves issue. They are now port fuel injected and the gas now washes over the intake valves cleaning them along the way providerd people use Tier 1 gasoline. At the same time the timing chain was redesigned so that is no longer an issue. Please respond as I have included my e-mail. Thank you,
Hi there, Michael Fennelly!
Thanks for the comment! Indeed, as of the recent updates Ford made to the 3.5 EcoBoost, the carbon buildup issue is far reduced. It still happens though, but only after a long while (estimated at around the 200-250k mile threshold), so it ought to make long-term maintenance and servicing way easier and less problematic.
What year were they re designed?
Will 3.5 twin turbo tow as much if not more than the 5.0? Also, will it be more fuel efficient than the 5.0?
Hi there, Selina!
While the 3.5 EcoBoost (non-hybrid) is a smaller engine, displacement-wise and cylinder-wise, the tow capacity is actually better than the 5.0 V8 – 14,000lbs vs 13,000lbs. The MPGs are slightly better with the 3.5 EcoBoost too; 18/23 MPG vs 17/22 MPG, city/highway.
I noticed that too!
Can e15 (88 octane)gas be used in the 2nd generation 3.5 ecoboost?
The use of E15 (88 octane) gasoline in the 2nd generation 3.5 EcoBoost engine, commonly found in vehicles like the Ford F-150, should be approached with caution. Generally, EcoBoost engines are designed to be flexible with fuel types, often capable of running on regular unleaded gasoline with an octane rating of 87 or higher. However, E15 fuel contains 15% ethanol, a higher ethanol content than the more common E10 gasoline.
Here are some considerations:
Manufacturer’s Recommendations: Always refer to the vehicle’s owner’s manual for specific fuel recommendations. Manufacturers typically specify the type of fuel that is best for the engine’s performance and longevity.
Ethanol Effects: Higher ethanol content in fuel can lead to issues in engines not designed for it. Ethanol can be more corrosive and may affect rubber seals and other components in the fuel system.
Octane Rating: The octane rating of E15 (88) is generally acceptable for most modern engines designed for regular unleaded gasoline. However, the specific tuning and design of the EcoBoost engine should be considered.
Warranty Considerations: Using a fuel type that is not recommended by the manufacturer can potentially void the warranty if it leads to engine damage.
Performance and Efficiency: While EcoBoost engines are designed to be efficient with turbocharging and direct fuel injection, the use of E15 may slightly alter performance or fuel efficiency due to the different combustion characteristics of ethanol-blended fuels.
For the 2nd generation 3.5 EcoBoost specifically, if there’s no explicit approval from Ford for E15 use, it’s safer to stick to E10 or regular unleaded gasoline. If E15 is approved, it should be used with the understanding that there may be some differences in performance and engine wear over time. Always prioritize the guidelines provided by the vehicle manufacturer to ensure optimal performance and to avoid any potential issues with the vehicle.
The comments re towing ability are disingenious. The V8 has a much wider power band compared to the V6, which makes towing easier and more flexible. As an example towing a loaded boat trailer up a launchng ramp from a standstill is much less problematic.
