Ailing United States car maker Chrysler has completed the sale of its strongest assets to a group led by Fiat, which has taken a 20% stake in the new Chrysler group.
The Italian company has secured its stake at no cost, contributing instead the technical know-how to make smaller, more fuel-efficient cars.
Fiat's stake may be increased if certain targets are met.
The asset sale completes a fast-track reorganisation for Chrysler, directed by the US government.
Other parts of Chrysler will remain in bankruptcy to be sold or closed.
However, analysts worry that the rebirth of Chrysler will be slow and painful, and may drag down Fiat.
The deal was completed after a US Supreme Court ruling clearing the sale.
