The Slant-Six is the popular name for a Chrysler inline-6 internal combustion engine with an overhead valve reverse-flow cylinder head and cylinder bank inclined at a 30-degree angle from vertical. Introduced in 1959 for the 1960 models, it was known within Chrysler as the G-engine. It was a clean-sheet design that began production in 1959 at 170 cubic inches (2.8 L) and ended in 2000 at 225 cubic inches (3.7 L). It was a direct replacement for the flathead Chrysler straight six that the company started business with in 1925 until the old design was discontinued in the 1960s.
