Land Rover AJ200P specs: 2.0L (122 ci) 4-cylinder, 83 x 92.3 mm (3.2677 x 3.6335 in) bore and stroke, 9.5:1 compression. Rated 296-398 hp, 2019–2026.
The Land Rover AJ200P is undersquare — the 3.6335" stroke exceeds the 3.2677" bore by 10.1% — a layout that trades peak RPM for leverage and torque low in the range. The 3.6335" stroke puts mean piston speed at 4,000 ft/min around 6,600 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 30.5 ci (500 cc).
9.5:1 is in the range that usually runs on pump premium.
10 factory variants share these dimensions, rated from 296 to 398 hp across 2019–2026.
