GMC LCV specs: 152 ci (2.5L) 4-cylinder, 3.465 x 3.976 in (88 x 101 mm) bore and stroke. Rated 193 hp, 2017–2021. Used in the GMC Acadia.
The GMC 152ci (LCV) is undersquare — the 3.9764" stroke exceeds the 3.4646" bore by 12.9% — a layout that trades peak RPM for leverage and torque low in the range. The 3.9764" 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 4 cylinders displaces 38.0 ci (623 cc).
It is one of 2 engines in the GMC 152ci family, all of them 152 ci — the differences between them are in compression, heads and rating, not displacement. 5 factory variants share these dimensions, rated at 193 hp across 2017–2021.
