Ferrari already builds the various V-8 engines currently used by Maserati, and previously it built the 4.5-liter unit that powered the Alfa Romeo 8C Competizione. In the future, we’re likely to see Ferrari’s expertise at engine building expanded even further, with reports recently emerging that Ferrari would be contracted to build new V-6 and V-8 engines for Maserati’s future lineup.

At last week’s 2012 Paris Auto Show, Fiat Group boss Sergio Marchionne said Ferrari’s engineering skills would also be utilized to enhance future Alfa Romeo powertrains. No specifics were given but Marchionne said all details would be revealed within the next two months, according to Fox News.

Marchionne is keen to see the Alfa Romeo brand return to its roots of building desirable and sporty cars. Alfa Romeo, along with Jeep, is seen by Marchionne as having the potential to be positioned as premium brands, though that will take some top-level products.

This means were likely to see a new Ferrari-designed engine, or perhaps just a Ferrari-enhanced unit, powering top-end Alfa Romeo models. The engine is believed to be a new V-6 unit that will also be shared with Maserati and feature forced-induction technology.

Unfortunately, these new plans, including delays in the redesign of the crucial 159-replacing Giulia, will likely push Alfa Romeo’s long-awaited U.S. return even further out.
