Mitsubishi 6A1x engine

The 6A1x is a series of V6 engines from Mitsubishi Motors, found in their small and medium vehicles through the 1990s. They ranged from 1.6 to 2.5 L in size, and came with a variety of induction methods and cylinder head designs & configurations.

Although now out of production, the 1600 cc 6A10 still holds the distinction of being the smallest modern production V6.
