Ferrari has confirmed that it has re-appointed former employee Luca Marmorini to oversee its engine department following the departure of Gilles Simon.

Head of engine operations at F1 rival Toyota for the past decade, 48-year old Marmorini returns to Maranello, where he began his career in the top flight 19 years ago. The Italian stepped down from his engine design role at Toyota earlier this season, and has been on the look-out for a chance to return to F1 since. He returns to Ferrari in the official capacity of head of engine and electronics as the Scuderia attempts to reclaim the glory days missing in 2009. The team has one just one race this season, with Kimi Raikkonen triumphing at Spa, having won a combined 14 titles in the twelve years with Simon overseeing operations.

The Frenchman moves on to unspecified 'other things' after 16 years with the Prancing Horse, including three at the head of the engine department after replacing Paolo Martinelli.

"Ferrari wishes to thank Gilles Simon for the important contribution he made during his time with the Gestione Sportiva, first, from 1994 to 2006 as head of engine design and then as head of the whole engine department," Ferrari said in a brief statement, "During that time, the V10 and V8 engines built at Maranello won six drivers' world championship titles and eight constructors', as well as taking 106 race wins."
