The Mitsubishi 4G63 (2013–2016) is close to square: 3.3465" bore against 3.4646" stroke, within 3.4%, which splits the difference between a high-revving layout and a torque layout. The 3.4646" stroke puts mean piston speed at 4,000 ft/min around 6,950 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).
