Ford’s 2.7 liter twin-turbo EcoBoost V6 first appeared in the 2015 Ford F-150 pickups, then the 2015 Ford Edge Sport, now the 2016 Lincoln MKX and soon the 2017 Ford Fusion Sport AWD. Here, it has the highest tune of them all at 335 horsepower and 380 pound-feet of torque, driving through its six- speed automatic transmission.
The engine itself isn’t just a smaller Ford 3.5 EcoBoost, but an entirely different design that has a unique block made of both compacted graphite iron for the upper section and aluminum for the lower half – the strategy to offer strength where its needed and save weight everywhere else.
It features two water-cooled turbochargers with waste-gates that bolt directly to aluminum heads that have integrated exhaust manifolds.
The design is not only less expensive to make, but offers better thermal efficiency and less turbo-lag.
Under this hood, it fits pretty snug and has a clean installation, with very little of the turbocharger plumbing visible.
The air comes into the filter box just above the grille and then splits in two different tubes to each turbocharger hidden down below. From there, air heads to an air-to-air inter-cooler up in front of the radiator, hidden from view as well.
After that the intake charge makes it back up into the engine, through the throttle body and into a plastic intake manifold that isn’t really all the pretty to look at.
The engine has direct fuel-injection so most of the fuel system hardware is underneath the valve covers. And like most new engines here we have dual overhead cams, both variable in timing by electronic cam phasers at the front of each head.
While it’s a tightly packaged engine bay, the service points are all within easy sight lines and reach. The air filter box is right up front, though it does take some effort to get open. A fuse panel is located next to it, and the battery is also under hood.
Windshield washer fluid and coolant reservoirs are located on the passenger side. Oil dipstick and filler neck right up front on the engine, and taking care of the brake fluid is done where you would expect it, ahead of the driver.
Looking back up front, notable items are the front radiator support made of molded composite, that’s plastic. Also an interesting point out are the power units for the optioned LED headlamps on our MKX, seen here on each side behind the light assembly.
The ECU is located back up in front of the passenger firewall, though in the MKX few will be looking for it to do any modifications. Another unique item, mostly hidden here is the electronics for the adjustable dampers for the Lincoln Drive Control system.
