    The 2015 Ford F-150's aluminum body is a big deal, but there might be even more innovation under the hood. The twin-turbocharged EcoBoost 2.7-liter V-6 is full of tricks, such as reducing overall mass by using iron and aluminum only where each metal's properties are most beneficial. The result is more than 300 hp in an extremely compact and lightweight design.





    A. Upper Block

    The most novel element of this engine is the two-piece block, with a single iron casting for the upper block, which includes the cylinders, and the main bearing caps (only the lower half of the block is aluminum). The bearing caps are laser etched and then cracked off to fit the crankshaft. Once reassembled, the three-dimensional mating surface for each cap provides extra stability. The match is so good that Ford has tested engines running without the caps bolted in at all.

    B. Lower Block

    Most engine blocks are made from a single material, but to save weight the 2.7-liter's lower ladder frame is die-cast aluminum and bolts onto the iron upper half. A second set of bolts secures the bearing caps to the ladder frame to further stiffen the engine. A composite oil pan seals up the bottom.

    C. Integrated Front Cover

    The IFC (no, not the cable channel) acts as a structural member that connects the major components of the engine. With its integrated water pump, oil passages for cam phasing, oil cooler, oil filter, and accessory drive components, the IFC arrives at the plant preassembled, streamlining the production process.

    D. Piston Rods

    Piston connecting rods have two ends—a big end that connects to the crankshaft and a small end that connects to the piston. The small end normally has a bushing, but Ford eliminated this by honing the wrist-pin hole and applying a high-durability coating along with optimizing the shape for better oil distribution. Removing the bushing not only saves money but also reduces the engine's overall height.

    E. Piston-Ring Seats

    There is a steel insert in each aluminum piston for the top oil ring to improve durability—a trick swiped from semi-truck engines. The engine also uses a tactic often seen in F1: Small holes in the lowest ring seats allow oil to escape to the crankcase, which minimizes drag from oil buildup at high speeds.

    Stop/Start

    This will be the first Ford truck engine with automatic stop/start capability. To prevent durability problems resulting from oil starvation every time the engine starts,a proprietary friction-reducing coating is applied to the main bearing races. A lifetime-wear test using dirty oil revealed almost no abrasion on the coated surface.

    Why the drop from 3.5L to 2.7L or are they both going to be in different vehicles?

    It's not really a drop, it's an all new engine. Previously Ford had nothing between the 2l and 3.5l Ecoboost engines. Now they've got the 2.3 and this 2.7 engine which can replace more of the NA lineup.

    Makes you wonder why they will go with the 2.3L in the Mustang instead of the new 2.7L V6?

    2.3L Ecoboost will be a fantastic engine but not as fantastic as the 2.7L with 2 more cylinders and an extra turbo.

    The 2.7 EB has been primarily designed for F150 as a diesel alternative,
    similar power and torque as the 5. 3V but with way better fuel economy.

    Makes you think about how much of a boat anchor that 5.4L 3V really is doesn't it lol?

    True. Double the cubes and probably double the weight as well. Less power and maybe less torque with double the economy.

    I agree, it would be a better option for Mustang... but that would be treading on the 5.0s toes. Although it'll never have the V8 bark a healthy ttv6 wouldn't sound all that bad. You will find the 2.3 is going to cause enough havoc anyway.
