The 3-cylinder powertrain of the new Superclass 1.2L has the greater fuel efficiency and the lowest emissions on its class.

Among many exclusive features, the pistons and piston-rings are coated with a special low-friction coating called DLC.

DLC stands for «diamond-like carbon» and is known for its ability to provide some of the properties of diamond to surfaces of almost any material.

The primary desirable qualities are hardness, wear resistance, and slickness.
