Ford Duratec 1.6 Ti-VCT specs: 97 ci (1.6L) 4-cylinder, 3.11 x 3.205 in (79 x 81.4 mm) bore and stroke. Rated 120 hp, 2011–2019. Used in the Ford Fiesta.
The Ford Duratec 1.6 Ti-VCT is close to square: 3.1102" bore against 3.2047" stroke, within 2.9%, which splits the difference between a high-revving layout and a torque layout. The 3.2047" stroke does not reach 4,000 ft/min of mean piston speed until about 7,500 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 4 cylinders displaces 24.3 ci (397 cc).
It is one of 2 engines in the Ford 97ci family, all of them 97 ci — the differences between them are in compression, heads and rating, not displacement. 9 factory variants share these dimensions, rated at 120 hp across 2011–2019.
