Ford EcoBoost Engines

What is a Ford EcoBoost engine? You might be considering buying a Ford model with an EcoBoost engine, or you might already own a vehicle with this technology and you’re trying to find out exactly what that means. Ford’s EcoBoost engines are a family of turbocharged, direct injected petrol engines; Ford’s answer to getting better gas mileage alongside increased performance. EcoBoost improves fuel economy by as much as 20% plus one huge perk: it costs much less than hybrid and diesel alternatives.

How It Works

Until now, the problem with smaller turbocharged engines was the lack of easily accessed power. This is where the Ecoboost family separates from the pack. Direct injection allows Ecoboost engines to reach maximum torque at daily driving speeds. A high-pressure mechanical fuel pump injects a fuel load directly into the combustion chamber, rather than the intake port, significantly reducing waste. This direct injection system works with the turbocharger to provide an impressive 16 psi of boost. The EcoBoost engines eliminate turbo lag and add power in the low rev range where it’s most needed. In the 3.5L EcoBoost V6 used in the F-150, power is generated via twin independent variable camshaft timing, resulting in greater control of valve actuation to enhance performance and efficiency.

EcoBoost Engine Types and Displacements

1.0 Liter EcoBoost Three-Cylinder

Ford 1.0L EcoBoost I3

Ford’s 1.0 Liter Ecoboost Three-Cylinder engine, developed at Ford’s Dunton Technical Centre in the UK, is the most innovative Ecoboost yet. The 1.0 Liter comes in 2 power versions creating either 99hp or 123hp. The more powerful version delivers 125lb-ft torque from 1,400 – 4,500 rpm, and 148lb-ft in overboost.  No larger than the size of a sheet of printer paper, these engines only weight about 213 pounds. Of the family, this is the only engine that uses a cast iron block instead of aluminum. This makes the engine about 20% heavier than its aluminum counterpart but increases the warm-up rate by 50%, also increasing fuel efficiency. This engine will be a viable option for the Fiesta, Focus, and C-MAX.

EcoBoost Four-Cylinder Engines

1.6L Ford EcoBoost I4 2.0L

Ford now as three four-cylinder EcoBoost engines in production. The 1.6L EcoBoost I4 engine that replaces it’s larger-displacement, naturally aspirated I4 counterpart. The 2.0L EcoBoost I4 engine that replaces it’s smaller-displacement, naturally aspirated V6 counterpart. The third is the all new 1.5L EcoBoost I4 that Ford has just officially announced. Ford will be replacing the Fusion’s 1.6L with the new 1.5L to better compete in a global market with virtually no drop in performance of the vehicle. The 1.6L engine is rated at 180hp and 180lb-ft of torque. The 2.0L  can range from 200hp – 252hp and 221lb-ft – 270lb-ft torque. This engine is available in the Explorer, Edge,  Escape, Fusion, Taurus, and Focus ST.

3.5L EcoBoost Six-Cylinder

3.5L Ford EcoBoost V6 F-150

The 3.5L EcoBoost V6 is the peak of power and performance for Ford. Using two Honeywell-Garrett GT15 turbos, the engine was designed to deliver power and torque output equivalent to the 6.0L or larger displacement naturally aspirated V8  engines with up to 15% better fuel economy and emissions. This engine delivers 365hp and 350lb-ft torque in the Explorer Sport, Flex, and Taurus SHO @ 5,000 rpm, and 365hp and 420lb-ft torque in the F-150 @ 2,500. Due to the low-end torque, the 3.5L EcoBoost can tow up to 11,300 pounds virtually better than any V8 could hope to, doing it quietly without severely reducing your average mpg.

Where do we see EcoBoost going in the future?

With the success of the EcoBoost engine already so great, Ford plans on extensively using it’s turbocharged, direct-injection technology on almost all of it’s future models. The displacements in the three-cylinder and four-cylinder engines will change in the next few years to better accommodate global markets, and the 3.5L V6 will continue to be used for SUVs and Trucks in the foreseeable future. The 2015 Mustang will see a 2.3L four-cylinder Ecoboost with roughly around 330hp, right in the middle of the current V6 and V8 engines.  Our fingers are crossed for an EcoBoost 5.0L V8 someday.
