Lincoln EcoBoost V6 specs: 164 ci (2.7L) 6-cylinder, 3.268 x 3.272 in (83 x 83.1 mm) bore and stroke. Rated 315 hp, 2024–2026. Used in the Ford Ranger. DOHC.
The Lincoln EcoBoost V6 is close to square: 3.2677" bore against 3.2717" stroke, within 0.1%, which splits the difference between a high-revving layout and a torque layout. The 3.2717" stroke does not reach 4,000 ft/min of mean piston speed until about 7,350 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 27.3 ci (448 cc).
It is one of 10 engines in the EcoBoost family, sitting between the 122 ci and 213 ci members. 3 factory variants share these dimensions, rated at 315 hp across 2024–2026.
