Chrysler M112 E32 specs: 195 ci (3.2L) 6-cylinder, 3.539 x 3.307 in (89.9 x 84 mm) bore and stroke, 10:1 compression. Rated 215 hp, 2004–2008.
The Chrysler M112 E32 is oversquare — the 3.5394" bore exceeds the 3.3071" stroke by 7.0% — a layout that favors airflow and RPM over leverage at the crank. The 3.3071" stroke does not reach 4,000 ft/min of mean piston speed until about 7,250 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 32.5 ci (533 cc).
10:1 is in the range that usually runs on pump premium.
It is one of 2 engines in the Chrysler 195ci family, all of them 195 ci — the differences between them are in compression, heads and rating, not displacement. 5 factory variants share these dimensions, rated at 215 hp across 2004–2008.
