Ferrari NV, fabled for its fast cars on roads and race tracks, is packing some extra speed into its factories, too. The Italian supercar maker, spun off from Fiat Chrysler Automobiles NV in 2016, plans to boost production by doubling assembly shifts to two a day in 2018 as deliveries are on pace to reach its 9,000-vehicle target a year earlier than scheduled, according to people familiar with the matter, who asked not to be named as the matter isn’t public.

A Ferrari spokesman declined to comment. The increase is part of Chief Executive Officer Sergio Marchionne’s plan to boost profit by expanding Ferrari’s line-up while maintaining the exclusivity of its $200,000-and-up models.
