Structural reinforcement required
by safety regulations for open - top vehicles means that the Spider inevitably weighs slightly more than the Alfa Romeo 4C coupé, but thanks to the use of carbon fibre for the rollover bars, spoilers and windscreen frame, as well as the adoption of a lightweight canvas soft top and the replacement of the glass rear screen with a continuation of the SMC * bodywork, the 4C's structural rigidity, mechanical
purity and low weight
philosophy are not compromised.
