They all sound catchy and futuristic, but one thing’s for sure: automotive manufacturers aren’t all about fancy naming their products. In fact, you may be able to subtract some valuable data from just the name of the engine, as long as you know what to look for. Let’s take for example Ford’s EcoBoost engine line, to better understand the subject at hand.
So, what is EcoBoost?
Pushed on the market back in 2009, the Ford EcoBoost engine lineup features a set of turbocharged petrol units, ready to adapt to the growing market which is at the moment highly focused on downsizing. While Ford is not the first automaker to switch to turbocharged engines, it was definitely a different story here, as its client base placed high value over the simplicity and reliability of Ford’s aspirated engines.
However, the EcoBoost line aims to provide the same amount of power from a small-capacity engine as higher displacement units do, all while also improving fuel efficiency by up to 20%. In company’s own statement “the 1.0-liter EcoBoost is as efficient as any diesel counterpart”.
Efficiency of Ford EcoBoost engines
Reducing cylinder displacement and turbocharging the air intake system means the engine block will be subjected to way higher stresses than regular aspirated units are. In order to counteract a possible mass engine failure, Ford pushed forward its Duratech technology, allowing EcoBoost engines to run for over a million miles in bench testing and also in prototypes.
Ford 1.0 EcoBoost engine is probably the one that caught most attention at its launch, featuring revolutionary technology. The 1.0 liter, three cylinder unit weighs only 97 kg, although it’s made of cast iron. The engine is available in 2 power versions: a standard 100HP unit and a more powerful 125HP. Ford decided to also add a non-turbocharged version to Fiesta.
The 1.5 EcoBoost engine was initially built to replace the 1.6 turbo unit; the ultimate purpose was to maintain power output while dramatically reducing the amount of fuel consumed. Introduced in 2014, the 1.5 liter unit was a success; inheriting technology from the 1.0 liter engine and featuring a redesigned cylinder head, the engine is able to cool down better and achieve a smoother ride and better performance. The standard version of the 1.5 liter EcoBoost delivers 150HP, while the top version reaches 180HP.
In terms of 4 cylinder blocks, Ford offers two EcoBoost versions: a 1.6 liter (150 and 180HP) and a 2.0-liter unit, producing 252HP and which can be found on the latest Focus ST.
The biggest in the class, a 3.5l EcoBoost V6 unit is to be found on Ford Fusion (355hp) or 265HP on Ford Explorer Sport. With a 60-degree layout and turbocharged by two Honeywell-Garrett GT15 units, the V6 EcoBoost is fully capable to replace the smaller block V8, all while producing more than enough power and torque scores.
A future Ford Mustang EcoBoost?
Ford plans to continue development on the EcoBoost engines, as they have been also applied on sport models such as the Mustang (a 2.3 liter, 300HP unit). The V6 will continue to rock pick-up and SUV models due to its high torque and fuel economy.
