Hybrid Chaplygin gas model is put forward , in which the gases  play the role of dark energy .
For this model the coincidence problem is greatly alleviated .
The effective equation of state of the dark energy may cross the phantom divide w = -1 .
Furthermore , the crossing behaviour is decoupled from any gravity theories .
In the present model , w < -1 is only a transient behaviour .
There is a de Sitter attractor in the future infinity .
Hence , the big rip singularity , which often afflicts the models with matter whose effective equation of state less than -1 , is naturally disappear .
There exist stable scaling solutions , both at the early universe and the late universe .
We discuss the perturbation growth of this model .
We find that the index is consistent with observations .
