Ford’s EcoBoost engine has only been on the market for three years, but has cornered the industry and become one of the best-selling truck engines of the decade. Since it’s introduction in the F-150 truck family, more than 500,000 EcoBoost engines have hit the road, saving customers more than 56 million gallons of gasoline.
Now, Ford has introduced two new EcoBoost engines: a 2.7L V6 that produces 325 hp and 375 lb.-ft. of torque and found in the 2015 F-150, and 2.3L that brings turbocharging and direct injection to the 2015 Mustang and boasts 310 hp and 320 lb.-ft. of torque.
The high-output, twin-turbo 2.7L EcoBoost V6 in the 2015 F-150 features an entirely new design that delivers power and performance in a strong, smart package. This engine, combined with the aluminum body, improves the power-to-weight ratio of the 2015 truck by 15 percent over the 2014 5.0L V8-equipped F-150 with similar torque output. The 2.7-L EcoBoost 4x2 has a maximum payload rating of 2,250 pounds and maximum tow rating of 8,500 pounds, ideal for meeting mid-range capability needs.
Boosting 2.7L EcoBoost fuel efficiency is the debut of standard Auto Start-Stop technology for F-150. This technology, specially tuned for truck customers, shuts off the engine when the vehicle is at a stop. When the brake is released, the engine restarts quickly. Auto Start-Stop helps reduce fuel consumption and emissions when the truck is stopped and the engine is off. The technology is off when towing or in four-wheel-drive mode.
The 2.7L EcoBoost engine also features Ford’s first use of a compacted graphite iron cylinder block in a gasoline engine, the same material used in Ford’s 6.7L Power Stroke® turbo diesel V8 in Super Duty trucks. The composite CGI/aluminum cylinder block saves weight while providing strength where it’s needed most for durability.
The addition of a new 2.3L EcoBoost engine brings turbocharging to the Mustang powertrain lineup. This engine is designed specifically for Mustang, to meet the needs of drivers looking for outstanding performance and fuel efficiency.
The geometry of the EcoBoost intake manifold and turbocharger housing is optimized to provide better breathing and higher output in the Mustang. Producing 310 hp and 320 lb.-ft. of torque, the 2.3L EcoBoost engine fits the bill for a true Mustang power plant – with the highest power density yet from a Ford engine.
As one of the newest members of Ford’s global EcoBoost engine family, the 2.3L continues to take advantage of state-of-the-art technologies including direct fuel injection, twin independent variable camshaft timing and turbocharging to produce big-engine power and torque with improved fuel efficiency.
The 2.3L EcoBoost is the first Ford engine to use a low-inertia twin-scroll turbocharger that provides quicker boost response while enabling lower emissions and improved efficiency. The cylinder head features an integrated exhaust manifold that separates the inner and outer pairs of cylinders into each of the two inlet passages to the turbo.
Keeping the exhaust pulses separated from the next cylinder in the firing order virtually eliminates mixing losses and maximizes the pulse energy to the turbine wheel. The result is similar performance to a more complex twin-turbocharger configuration, meaning quicker turbine spin-up and torque delivery when the driver needs it for passing maneuvers.
