The Jeep Tigershark 2.4 MultiAir is undersquare — the 3.8189" stroke exceeds the 3.4646" bore by 9.3% — a layout that trades peak RPM for leverage and torque low in the range. The 3.8189" stroke puts mean piston speed at 4,000 ft/min around 6,300 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 36.0 ci (590 cc).
10:1 is in the range that usually runs on pump premium.
It is one of 2 engines in the Jeep 144ci family, all of them 144 ci — the differences between them are in compression, heads and rating, not displacement. 8 factory variants share these dimensions, rated from 177 to 180 hp across 2015–2022.
