The Mitsubishi 6A1 engine is a series of piston V6 engines from Mitsubishi Motors, found in their small and medium vehicles through the 1990s. They ranged from 1597to in size, and came with a variety of induction methods and cylinder head designs and configurations.

Now out of production, the 1597cc 6A10 is still the smallest modern production V6. The small displacement was offered so Japanese buyers could purchase a powerful engine, while reducing their annual road tax obligation.
