Back in November, Ford Authority exclusively reported that The Blue Oval was working on developing a straight-six Ford EcoBoost engine, but ultimately decided to cancel that particular project several years ago during the COVID-19 pandemic. The plan at that time was to base this straight-six off of the existing 1.5L I-3 EcoBoost powerplant that’s currently standard equipment in the Ford Escape and Ford Bronco Sport. It’s unclear what sort of displacement this larger I-6 would have offered buyers, nor what kind of power it was targeted to make. However, we do know what vehicles this new Ford engine would have been used in if it had indeed come to fruition.
The inline-six-cylinder Ford engine was slated to be used in a variety of Blue Oval models – the Ford F-150, Ford Expedition, Lincoln Navigator, and Lincoln Aviator, sources familiar with FoMoCo’s plans have told Ford Authority. While it’s unclear what sort of output Ford was targeting for its I-6, that powerplant was slated to take the place of the twin-turbocharged 3.5L V6 EcoBoost in the automaker’s more premium offerings. In high-output form, that powerplant generates as much as 450 horsepower and 510 pound-feet of torque.
With the cancellation of this I-6 Ford engine, the EcoBoost family soldiers on with the 2.7L V6 EcoBoost, 3.0L V6 EcoBoost, and 3.5L V6 EcoBoost in terms of six-cylinder engines, all of which feature cylinders that are arranged in a “V” configuration rather than lining up straight. Had FoMoCo decided to move forward with its I-6, it would have been the fourth six-cylinder powerplant in the Ford EcoBoost lineup.
In the meantime, several other automakers have moved forward with plans to launch new straight-six engines in recent years, including Mazda with the all-new CX-90 and its turbocharged 3.3L inline-six cylinder engine coupled with a 48-volt hybrid system, as well as Stellantis’ Hurricane I-6 that’s offered in a variety of models – including the forthcoming, refreshed 2025 Ram 1500.
