2.7 Vs. 3.5 Ecoboost: In-Depth Discussions
Both the 2.7 and 3.5 EcoBoost engines can also be upgraded in a very straightforward manner to make a lot more power.
Engine generation is one of the most important factors. Each EcoBoost engine has a 2nd generation version that was introduced in 2017 & 2018, respectively. Each engine received some improvements that improved tuning potential and performance.
The 2.7 EcoBoost has an effective advantage compared to 3.5 EcoBoost. Since fuel efficiency depends on a number of different factors, it is difficult to dive into specifics. How much does the F-150 weigh? Is it 4WD or RWD, etc.? Regardless, the 2.7 EcoBoost will get approximately 2-3 more MPG when compared to the 3.5 in a similarly equipped F-150.
However, towing may offer a similar fuel economy between the 2.7 and 3.5 EcoBoost. A Ford 3.5-L twin turbo engine may actually be able to outperform some cars in certain situations. Because the engine is more significant, it doesn’t need to use turbo boost as often due to its larger displacement.
Compared to the 2.7 EcoBoost, the 3.5 EcoBoost is capable of towing about 4,000 lbs and more. In fact, the 3.5L engine on the F-150 offers the best towing capacity. The same applies to payload capacity. Most F-150 owners, however, will probably be happy with their 2.7-L engine’s towing capacity.
3.5 EcoBoost is the better option if you plan to tow heavy loads often. It is not just because it can tow more weight than the F-150. When towing heavy loads, the 2.7-L EcoBoost relies significantly more on turbochargers. Because of the larger displacement of the 3.5-EB, it offers considerable advantages. The turbo will not be necessary as much.
Since we wrote a lot about Ford’s 2.7 and 3.5 EcoBoost engines’ reliability, we have a lot of experience with this topic. In some cases, it is simply a matter of luck. Nonetheless, proper maintenance should help the EcoBoost 2.7 and 3.5 engines perform well.
For the 2nd generation 3.5L and 2.7L engines, Ford introduced port injection to address this issue. On the 2.7 EcoBoost as well, timing chain issues were resolved as well as oil pan issues.
In terms of long-term reliability, there is a lot of space for debate between the 2.7 and 3.5 EcoBoost engines. Which engines last longer in general? There is no definitive answer as of yet.
Nevertheless, the 2.7 and 3.5 EcoBoost engines should last for up to 200,000 miles on average. Exact longevity depends on numerous factors, of course. The engine’s longevity will be affected by many factors, including how it is used, maintained, driven, etc. Regardless, we’re huge fans of either EcoBoost engines in the F 150, so which is actually better may be left up to luck.
You may be better off choosing the 3.5 engine if you are looking to move heavy loads. Towing capacity is greater because the 2.7 engine is smaller, not just because the engine has more power.
As a result, the engine uses its turbos more often. With the 3.5 engine, however, you won’t need as much turbocharger power because you’ll have such a large displacement that you won’t need them excessively. A 3.5-liter engine can easily handle heavier loads instead of a 2.7-liter engine.
Boosts And Stress
However, both engines have been built to their maximum potential. The process of carrying heavy loads enables them to handle any kind of stress and boosts.
It might be a good idea to know which motor is best for the specific purpose for which your truck was made since they are very important in the process. 3.5 engines win clearly in this contest, and that is the clearest answer to this question.
2.7 Vs. 3.5 Ecoboost: Which Is The Best Option?
Are you driving an Ecoboost 2.7 or 3.5? What is your preferred engine? It has been too long since 2.7 vs. 3.5 EcoBoost engines were debated. It may be easier to reduce car fuel consumption with a 2.7 engine. However, a 3.5 engine will actually help you handle heavy loads.
Thus both engines do an amazing job without having to exert much effort. Because both machines are pretty similar, you can decide which is better for you. Putting all of this discussion together, the decision to buy an engine entirely depends on your needs.
Which is better, the 2.7 or the 3.5 EcoBoost?
The 3.5 EcoBoost is a definite choice if you are looking for maximum performance and towing capacity.
How many miles will a 2.7 EcoBoost last?
F150 2.7 EcoBoosts can achieve a maximum reliable mileage of around 200k- 230k miles.
In terms of performance, towing, fuel economy, and reliability, a Ford EcoBoost engine is one of the most reliable on the market in the F-150. 2.7 vs. 3.5 Ecoboost engines differ in a number of ways, including engine block material. Both engines share many other characteristics, though. Both the 2.7 and 3.5 EcoBoost engines have twin turbocharger, direct injection, DOHC V6 engines featuring Ti-VCT technology.
The new 2nd gen EcoBoost engines deliver better reliability than the 2.7 vs. 3.5 EcoBoost. Overall, the Ford F-150 EcoBoost engines perform exceptionally well. Choosing between them will just depend on what you want and need.
