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.
