2015 Ford Mustang Convertible 2.3-liter EcoBoost

The new 2.3-liter EcoBoost engine brings turbocharging to the Mustang powertrain lineup. Designed to meet the needs of drivers looking for outstanding performance and projected best-in-class fuel efficiency, this EcoBoost engine has been developed specifically for Mustang. The intake manifold and turbocharger housing are optimized to provide better breathing and higher output in Mustang.

With a projected 305-plus horsepower and 300-plus lb.-ft. of torque, this EcoBoost engine fits the bill for a true Mustang powerplant.

"This EcoBoost engine delivers the healthy output that Mustang drivers expect regardless of the speed," said Scott Makowksi, EcoBoost powertrain engineering manager. "This EcoBoost engine might be small in displacement, but it delivers where a Mustang driver expects it with a broad, flat torque curve and great driveability under any conditions."

The newest member of Ford's global family of EcoBoost engines, the 2.3-liter 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.

This is the first Ford engine to utilize 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 inlet passage to the turbo.

Keeping the exhaust pulses separated from the next cylinder in the firing order eliminates mixing losses and maximizes pulse energy to the turbine wheel. The result is quicker torque delivery when the driver needs it for passing maneuvers and similar performance to a twin-turbocharger configuration.

The separated exhaust ports also enable the exhaust valves to stay open longer for reduced pumping losses that improve specific fuel consumption by about 1 percent.
