Introduced in 2023, the SF90 XX Spider created Maranello history by translating the extreme engineering ethos of the XX Programme to a road-legal open supercar. Positioned against ultra-exclusive drop-tops such as the McLaren 765LT Spider, it goes far beyond conventional limited-edition exotics by combining radical circuit downforce with an electrified powertrain. Studying Ferrari SF90 maintenance reveals that maintaining this 1,030 hp open prototype requires treating its fixed aerodynamics, hybrid battery and retractable hardtop as an indivisible high-stress system.
