The EcoBoost moniker doesn’t apply to any specific engine as the name appeared on several different engines over the years. It’s really the name of the technology applied to the engine. According to Ford, EcoBoost technology is comprised of three different parts. First, turbocharging, hence the “Boost” name is the most obvious. Turbocharging, for the most part, is an efficient way to squeeze power from an engine as it puts the exhaust gases to work instead of allowing them to escape from the engine. Second, an EcoBoost engine utilizes direct injection. Direct injection allows fuel injectors to spray fuel into the combustion chamber a lot more precisely and in turn, use less fuel. Lastly, Ford uses twin independent variable camshaft timing to put the icing on the cake that is the EcoBoost line. That technology allows the camshafts at the top of the engine to operate in a way that optimizes power when it’s needed while saving fuel.
All the EcoBoost technology culminates in the Ford GT. The GT is equipped with a 3.5-liter EcoBoost motor that, in stock form, generates 660 horsepower. The hyper-limited GT Mk IV boosts that to 800. That 3.5-liter V6 generates more power than the Lamborghini Aventador’s 769 horsepower 6.5-liter V12.
