Over the past few months, Ferrari has been caught testing mysterious prototypes based on the LaFerrari. We assumed these were test mules for the LaFerrari's future successor, but it turns out the company may have been testing a special limited-edition supercar based on the wild, double-named Ferrari.

According to a post on the Ferrari Chat forum, Ferrari's next special masterpiece will debut later this year at the Ferrari World Finals taking place at the Mugello racetrack in Italy on November 16-22. Following the Monza SP1 and SP2 speedsters, this will be the third car in Ferrari's Icona series of limited-run supercars.

Based on the 812 Superfast, the Monza SP1 and SP2 were inspired by classic 1950s Ferrari race cars like the 750 Monza and 860 Monza. Ferrari's next one-off project, on the other hand, is allegedly inspired by the iconic Ferrari 330 P4 that raced at Le Mans in the 1960s and appeared in Ford V. Ferrari starring Christian Bale and Matt Damon.

Power will be sourced from the sublime 6.5-liter naturally aspirated V12 that powers the 812 Competizione where it generates 819 horsepower and 510 lb-ft of torque. Power is expected to be sent to the rear wheels through an eight-speed dual-clutch transmission.

But while the 812 Competizione is front-engined, Ferrari's next Icona car will be based on the same platform as the mid-engined LaFerrari Aperta with bespoke styling paying homage to the curvaceous 330 P4. Unlike the LaFerrari, it won't have a hybrid powertrain.

Just a few days ago, the company was caught testing another heavily camouflaged LaFerrari. Given the timing, this was likely a test mule for Ferrari's new Icona. Production of the SP1 Monza and SP2 Monza was limited to just 499 examples combined. Members of the Ferrari Chat forum believe the new Icona will be even rarer, with production limited to around 300 examples each costing between $2.5 million and $3 million. We'll find out more details when the retro-inspired one-off Ferrari codenamed F171 debuts in November.
