Jeep EXF specs: 182 ci (3.0L) 6-cylinder, 3.268 x 3.622 in (83 x 92 mm) bore and stroke. Rated 240 hp, 2014–2019. Used in the Jeep Grand Cherokee. DOHC.
The Jeep EcoDiesel (EXF) is undersquare — the 3.622" stroke exceeds the 3.2677" bore by 9.8% — a layout that trades peak RPM for leverage and torque low in the range. The 3.622" stroke puts mean piston speed at 4,000 ft/min around 6,650 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 30.3 ci (497 cc).
It is one of 5 engines in the EcoDiesel family, all of them 182 ci — the differences between them are in compression, heads and rating, not displacement. 5 factory variants share these dimensions, rated at 240 hp across 2014–2019.
