Chevrolet LL0 specs: 76 ci (1.2L) 4-cylinder, 2.776 x 3.15 in (70.5 x 80 mm) bore and stroke. Rated 84 hp, 2013–2015. Used in the Chevrolet Spark.
The Chevrolet 76ci (LL0) is undersquare — the 3.1496" stroke exceeds the 2.7756" bore by 11.9% — a layout that trades peak RPM for leverage and torque low in the range. The 3.1496" stroke does not reach 4,000 ft/min of mean piston speed until about 7,600 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 4 cylinders displaces 19.0 ci (311 cc).
3 factory variants share these dimensions, rated at 84 hp across 2013–2015.
