# Mitsubishi 6A1 engine

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 1.6 to 2.5 L (1,597 to 2,498 cc) in size, and came with a variety of induction methods and cylinder head designs and configurations.
Now out of production, the 1.6 L (1,597 cc) 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.
