The car maker plans to sell around 10% of the supercar maker to investors. Another 10% of what will be called Ferrari NV will remain in the ownership of Piero Ferrari, the son of Enzo Ferrari.
The remaining 80% of the shares in the newly independent supercar maker will be distributed to existing Fiat Chrysler shareholders.
In July Fiat Chrysler boss Sergio Marchionne said he expected Ferrari to be valued at "over £7 billion". Analysts have pointed out that such a figure would mean Ferrari represented 60% of the whole value of the Fiat Chrysler combine.
If the market eventually values Ferrari NV at around £8bn, it would mean Fiat Chrysler would raise £800m in cash from share sales and distribute around £6.4bn in value to Fiat Chrysler shareholders.
This distribution of Ferrari shares should help Fiat Chrysler raise fresh funds from the shareholder. The money is expected to be partly invested in future new Alfa Romeo models.
