There's technically no 2017 4C Spider; demand one from your Alfa dealer if you're interested. As for the coupe, there's a new upgraded Alpine audio system, a new Giallo Prototipo Yellow color, and a new dual-mode exhaust system from aftermarket supplier Akrapovic. A new carbon-fiber roof is available for the 4C Coupe.
Besides an available Carbon Fiber Trim package, the 2016 Alfa Romeo 4C is fitted with a new Alpine stereo, upgraded speakers and a lockable console (4C coupe). A premium leather interior upgrade is also available, as is a dual-mode electronically controlled exhaust from Akrapovič.
