Underneath, the Alfa Romeo 4C Spider will feature the same 236 hp 1.75-litre four-cylinder engine with a six-speed dual-clutch gearbox as the coupe. The combination of the low weight with a power dense engine means the 4C Spider should be capable of hitting 100 km/h sprint in 4.5 seconds and a top speed of more than 250 km/h.

As for the roof mechanism, a single large rollover bar made from carbon fibre is expected to be featured alongside a folding soft top. All up, the 4C Spider is expected to tip the scales at just 60 kg more than the lightweight coupe.
Alongside the removal of a fixed roof, the Alfa Romeo 4C Spiders will feature more traditional headlights like the 4C Spider Concept unveiled at the Geneva Motor Show 2014. Additionally, a set of carbon fibre air intakes on the side skirts and not present on the 4C coupe will be included.
