Ford Duratorq 3.2 specs: 195 ci (3.2L) 5-cylinder, 3.539 x 3.965 in (89.9 x 100.7 mm) bore and stroke, 15.8:1 compression. Rated 185 hp, 2015–2019.
The Ford Duratorq 3.2 is undersquare — the 3.9646" stroke exceeds the 3.5394" bore by 10.7% — a layout that trades peak RPM for leverage and torque low in the range. The 3.9646" stroke puts mean piston speed at 4,000 ft/min around 6,050 RPM, which is where a production bottom end is generally considered at its limit. Each of the 5 cylinders displaces 39.0 ci (639 cc).
At 15.8:1 this is a compression-ignition engine: the ratio is the heat source that lights the fuel, not a knock limit to be managed.
It is one of 2 engines in the Ford 195ci family, all of them 195 ci — the differences between them are in compression, heads and rating, not displacement. 5 factory variants share these dimensions, rated at 185 hp across 2015–2019.

| Bore/stroke character | 0.893 — undersquare — stroke exceeds bore, which favours low-end torque |
|---|---|
| Mean piston speed at 6,000 RPM | 3,965 ft/min — in the range typical of performance street engines |
| Displacement per cylinder | 39.0 ci |
| Static compression | 15.8:1 — high enough that pump premium or better is normally required |
