The Ford's engineers decided to move forward in the development of downsizing strategy. Together with a close-coupled three-way catalytic converter and applied advanced technologies, the engine meets the tough European emission standard - Euro 6. The engine operation is controlled by an electronic drive-by-wire throttle body and Bosch MED17 ECU. The high-pressure direct injection system injects fuel directly inside combustion chambers via 6-hole injectors mounted on the head in the center of each cylinder (close to spark plugs). The 1.5 EcoBoost features a high-response Borg Warner low-inertia turbocharger with an active wastegate and a water-to-air charger-intercooler integrated into a plastic intake manifold. By the way, the electronically controlled variable displacement oil pump also is driven by belt-in-oil designed for the entire life of the engine.Д®coBoost engines are very efficient due to the combination of turbocharger and direct fuel injection. There is a timing belt, but this belt operates in engine oil that reduces noise and increases durability. The 1.5l engine borrowed an innovative camshaft drive system from the 1.0 I-3 cylinder engine. The exhaust and the intake camshaft are equipped with variable valve timing - Ford's Twin independent Variable Cam Timing (Ti-VCT). Like previous head, it has 4 valves per cylinder (16 two exhaust valves and two intake valves 16 valves total) actuated via solid buckets by two overhead camshafts (DOHC design). The heat from exhaust gases warms up the engine more quickly, at the same time the reduced exhaust temperature prolongs the life of the turbocharger. The engine received a redesigned aluminum cylinder head with an integrated exhaust manifold. The reduced displacement was achieved by using a crankshaft with a short stroke (76.40 mm). The engine block kept the same bore size. Aluminum pistons are hypereutectic and have asymmetrical skirts with a friction-reducing coating.

A hot-forged powder metal process and a cracked rod cap process is used in the connecting rods manufacturing process. The engine was equipped with a new cast iron crankshaft with 4 counterweights and 5 main bearings. It also has an open deck design for an efficient cooling. Like the 1.6 EcoBoost, the 1.5l engine has an aluminum cylinder block with cast iron sleeves.
