The new 2015 Lincoln MKC, the newest addition to the small premium utility market, will feature a new 2.3-liter EcoBoost engine. The new engine will be the latest addition to the Ford EcoBoost engine family.
The 2.3L four-cylinder will continue the EcoBoost name. EcoBoost engines are named for their key technological advances such as forced induction, variable valve timing, and direct injection. The 2.3L EcoBoost is no exception. The small engine produces an impressive 275 horsepower and 300 lb.-ft of torque at 3,000 rpm, according to early tests. This is an upgrade of around 35 horsepower and 30 lb.-ft of torque above the 2.0L EcoBoost found in the standard MKC.
Ford attributes the improved power figures mainly to their advanced turbocharging technology. The 2.3L EcoBoost uses a twin-scroll turbocharger, which spools quickly to minimize turbo lag. The engine also uses a three-port integrated exhaust manifold (IEM). The triple-port IEM pairs the exhaust gas of the outer and inner cylinders before feeding into the turbine exhaust housing. The result is a smoother flow of exhaust gases to the turbocharger, ultimately a more efficient way to take advantage of the twin-scroll turbo.
“The three-port IEM design is the key driver for performance because it improves airflow and optimizes exhaust energy pulses through the turbocharger,” said Pete Pandolfi, engine supervisor for Lincoln. “The three-port IEM and twin-scroll turbo design really opened us up to have outstanding power and refinement.”
Another advantage to the EcoBoost development philosophy is the fuel economy, relative to the power output. Ford engineers pride themselves on creating engines that have power comparable to larger displacement engines, without any of the drawbacks for fuel efficiency. The 2.3L EcoBoost, thanks in part to the IEM system, keeps its exhaust valves open longer than most engines which allows it to run more efficiently. No fuel economy figures have been released for the Lincoln MKC as of yet, but Lincoln claims the 2.3L EcoBoost will get up to 15 percent better fuel economy than the six-cylinders in its class with little to no drop in power.
The 2015 Lincoln MKC will come standard with the 2.0L EcoBoost and a front-wheel drive layout, and the 2.3L and all-wheel drive will be available as optional extras. Production of the MKC will begin in 2014, and models will be on the showroom floor next summer.
