Ford Duratec 35 Ti-VCT specs: 213.4 ci (3.5L) 6-cylinder, 3.642 x 3.413 in (92.5 x 86.7 mm) bore and stroke. Rated 288 hp, 2013–2019. Used in the Ford Taurus.
The Ford Duratec 35 Ti-VCT 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 35.6 ci (583 cc).
It is one of 17 engines in the Cyclone V6 family, the largest at 213.4 ci. 7 factory variants share these dimensions, rated at 288 hp across 2013–2019.
