The convertible version of the two-seater 4C gets the same enhanced equipment offered with the coupé, including an upgraded stereo, increased leather interior trim on the glovebox, luxury floor mats and a bespoke car cover. It also comes with a carbonfibre windscreen frame and more wheel options.
The headlights, which feature a plastic cover rather than a series of open spotlights, are closer to those of the 4C concept than the original coupé. The same headlights are now available as an option on the coupé. It is also available with cruise control and rear parking sensors as no-cost options.
The key element differentiating the 4C Spider from the 4C Coupé launched in 2013 is its removable roof. It will initially be available as a soft, stowable canvas arrangement - as hinted at on the concept - although an optional carbonfibre hard-top is set to become available after UK sales begin in mid-2015, according to Alfa officials.
The 4C Spider also receives a carbonfibre panel that covers the rollover bar behind the cabin, unique single-lens headlights and a new range of alloy wheels, which measure 17in in diameter up front and 18in at the rear.
In a move that has kept the weight gain down to just 10kg (at 1128kg) while retaining a level of rigidity described as being similar to that of the 4C Coupé, the 4C Spider has a carbonfibre windscreen frame that is bonded and bolted to its carbonfibre monocoque chassis.
The glass for both the windscreen and side windows is described as being 10% thinner than that on the 4C.
