It is quite common for us to link Mazda together with Ford, especially on their engine technologies, a different Mazda and Ford model can be possible sharing the same engine, Mazda new L series engine may have some relation to the Ford Duratec engine.
From Wikipedia,
The Mazda L-series is a mid-sized inline 4-cylinder gasoline engine ranging in displacements from 1.8L to 2.5L. Introduced in 2001, they are the evolution of the cast-iron block F-engine. This engine is designed by Mazda and is also used by Ford as their 1.8L to 2.5L 'Duratec' world engine.
The L-engine uses a chain-driven DOHC, 16-valve valvetrain with an all-aluminum block construction and cast-iron cylinder liners. Also featured are intake cam-phasing VVT, VTCS, VICS, a stainless steel 4:1 exhaust header and a lower main bearing cage for increased block rigidity. Direct-injection is available on the 2.0L LF-VD and the award-winning (DISI) turbocharged L3-VDT engine introduced in 2006 for the Mazdaspeed lineup of vehicles.
As of 2010, Ford is introducing a GDI turbo variant of the Mazda LF engine design as the EcoBoost 2.0L. They have developed their own manifold and engine control systems for use with the direct-injected, turbocharged EcoBoost. Ford plans to use the L-engine, as well as the Z-engine, well into the future for their EcoBoost and Duratec 4-cylinder generations. As of 2011, Mazda will cease to develop the L-engine, to be replaced by the SKYACTIV P-engine. At this time, Ford will be the only manufacturer still using the Mazda L- and Z-engine designs.
