Alfa goes soft on 4C Spider roof
Open season: Alfa's 4C Spider will have a targa fabric roof that can be rolled up and stored in the boot.

THE open-air version of Alfa Romeo's 4C sports coupe will get a soft top rather
than a lift-out hard top panel, not only because it saves weight but also
because there is no room to store a solid roof in the tight confines of the
Alfa head exterior designer and chief designer for the 4C, Alessandro
Maccolini, said the targa-style fabric roof would have solid rails on each
side, above the doors, that clipped to the car's carbon-fibre windscreen frame
and roll bar.
These could be unclipped and the roof rolled up and stored in a special
protective holder in the small (110 litre) boot behind the mid-mounted engine.
Mr Maccolini said the solution was similar to that of the Lotus Elise, and
meant that the driver could take the roof along in the car in case the weather
turned bad or they wanted to leave the car unattended in the street.
The 4C Spider revealed at the Geneva motor show was shown without a roof, and
no visible way of securing one.
GoAuto understands that the final design of the roof and the engineering
solutions to seal it from the weather are still under development.
Mr Maccolini said the “pre-series car” at Geneva was otherwise close to
Set to go into production in the second half of this year and on sale in
Australia before Christmas, the Spider shares the same 177kW four-cylinder
petrol engine and carbon-fibre construction as the coupe that is already on
sale in Europe and due in Australia in the third quarter.
But Mr Maccolini said the Spider differed from the coupe in a number of areas,
including the roll bar area behind the seats, which had be redesigned to
accommodate the lift-out roof.
The Spider also gets more conventional headlights in place of the polarising
naked carbon-fibre-and-LED units of the coupe.
The good news is that, according to Mr Maccolini, 4C buyers will be able to
choose which headlight design they want, overcoming one criticism of the 4C.
Those who want the conventional headlights with their clear plastic cover will
pay a 2kg weight penalty, however.
Mr Maccolini did not disclose the overall weight of the Spider, but conceded it
would be more than the featherweight 895kg of the coupe in unladen form.
Unveiling the Spider at Geneva, Alfa Romeo CEO Harold Wester said the topless
version would way “well below 1000kg”, and that the “war on weight” that had
been waged on the coupe had continued on the Spider.
Mr Maccolini said the 4C's designers had trimmed the body design down to the
bare minimum, and cloaked it over the inner workings of the car as tightly as
This meant there was no room for anything under the front of the car, except
for the radiator, suspension and structural elements.
A small boot was designed into the crush area of the rear of the vehicle, and
that was the only place to store a roof.
Most other targa-topped cars have a lift-out aluminium panel. In the case of
the original Honda NSX open-top model, the roof could be slotted into a special
cradle above the mid-mounted engine bay.
Mr Maccolini said it was also unacceptable not to have a roof that could be
carried in the car.
Australian journalists were shown an early full-sized design prototype of the
Spider at Fiat Chrysler Automobile's Turin design studios, but the roof was a
fake panel without the proper workings of the series production soft-top.
However, it was cloaked in black fabric, indicating that all Spiders are likely
to get the traditional black fabric on their roofs.
