Though we can't verify its sources, 4WheelsNews says it has double confirmation from within Ferrari that a 458 Speciale Spider is in the works. When reached for confirmation, Ferrari refused to comment, as it typically does on the prospect of new models yet to be announced. Given the precedent of the Scuderia Spider 16M, it would seem to make sense, but for the time being we'll have to chalk this one up as a rumor.
If it were built, the Ferrari 458 Scuderia Spider (or whatever it would ultimately be called) would take the best of the 458 Spider and 458 Speciale to pack the 600-horsepower version of Maranello's sweet-revving 4.5-liter V8 underneath a folding hardtop. The latter is something the 16M did not offer, but crucially, the new McLaren 650S Spider does. We'd also expect only a limited number to be produced at a suitable premium over the Spider's $257k MSRP and the Speciale's $288k sticker.
