GM crosstown rival Ford Motor Company was reportedly developing a new turbocharged inline six-cylinder engine for use in a variety of pickup and utility vehicle models before the new engine project was ultimately canceled. Interestingly, General Motors was also working on a turbo inline six-cylinder around roughly the same timeframe before The General also decided to can the project. Meanwhile, Stellantis introduced its new Hurricane twin-turbo inline ‘six in March of the 2022 calendar year.
Per an exclusive report from out sister publication, Ford Authority, FoMoCo was previously working on a new straight-six based on the turbo 1.5L I3 EcoBoost engine that currently powers the Ford Escape and Ford Bronco Sport. The exact displacement and output targets for the turbo ‘six are unclear, but Ford Authority reports that the new engine was slated for use in the F-150, Expedition, Lincoln Navigator, and Lincoln Aviator. For the sake of reference, that the Blue Oval brand’s twin-turbocharged 3.5L V6 EcoBoost engine produces upwards of 450 horsepower and 510 pound-feet of torque in high-output guise.
Interestingly, General Motors had similar plans at one time. In May of 2022, GM Authority exclusively reported that The General was in the planning stages for development of a new turbo six-cylinder engine as part of the automaker’s Cylinder Set Strategy (CSS). It’s believed the engine would have been similar to the current turbo 2.7L I4 L3B gasoline engine, plus two extra cylinders, with an output target around 500 horsepower and 500 pound-feet of torque. GM Authority reported in March of 2023 that the project was canceled.
Meanwhile, Stellantis launched its new twin-turbocharged 3.0L I6 engine in March of the 2022 calendar year. Dubbed the “Hurricane”, high-output variants dole out as much as 540 horsepower and 521 pound-feet of torque.
