Lincoln 3.5 EcoBoost specs: 213 ci (3.5L) 6-cylinder, 3.642 x 3.413 in (92.5 x 86.7 mm) bore and stroke. Rated 380-450 hp, 2015–2026.
The Lincoln 3.5 EcoBoost is oversquare — the 3.6417" bore exceeds the 3.4134" stroke by 6.7% — a layout that favors airflow and RPM over leverage at the crank. The 3.4134" stroke does not reach 4,000 ft/min of mean piston speed until about 7,050 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 35.5 ci (582 cc).
It is one of 15 engines in the EcoBoost family, the largest at 213 ci. 12 factory variants share these dimensions, rated from 380 to 450 hp across 2015–2026.
