The Alfa Romeo 4C Spider has been spied in production form, ahead of an official unveiling early in 2015.
As with the concept car, unveiled at the 2014 Geneva motor show, the production car sports a canvas roof and the new-look headlight, wheel and exhaust designs as seen on the latest coupé.
At the launch of the concept car, Alfa said the car’s weight gain had been limited to 60kg over the coupé thanks to the use of a lightweight canvas roof plus carbonfibre rollover hoops, spoilers and windscreen frame. Alfa also said it had crafted the aerodynamics of the car to minimise roof-down turbulence. All of these are expected to make production.
The dual-stage central exhaust system uses titanium and carbonfibre tailpipes and has been developed by renowned motorbike racing exhaust manufacturer Akrapovic, which has worked in MotoGP, superbikes and motocross. It has an electrically operated valve system that can improve performance and enhance the exhaust note at the push of a button.
The 4C Spider is expected to otherwise be identical to the coupé, with power coming from the same four-cylinder, all-aluminium, 1750cc turbocharged petrol engine which drives the rear wheels via a six-speed dual-clutch automatic transmission. Alfa says 0-62mph takes 4.5sec and top speed is in excess of 155mph – the same as the coupé. Weight distribution also remains 40/60 front to rear.
