The new Alfa Romeo 4C Spider employs the same lightweight carbonfibre monocoque and aluminium chassis as the hard-top version, with its all-aluminium 1.75-litre turbocharged four-cylinder engine sitting amidships with drive going to the back wheels through a standard twin-clutch automatic transmission.
Power figures for the 4C Spider go unchanged compared to the coupe version, with 177kW of power and 350Nm of torque wrapped up in a lithe body.
The increased weight of the convertible components (reportedly up by just 10 kilograms: so it should be 1035kg, compared to the coupe's 1025kg kerb weight in Australia) does little to impact the performance figures on offer: Alfa Romeo claims a 0-100km/h time of just 4.5 seconds, identical to the coupe version.
Also identical to the coupe are leather-trimmed seats, a leather-trimmed flat-bottomed steering wheel with paddleshifters, aluminium pedals.
The 4C range is built in Modena, Italy, and first Australian deliveries of the car will commence in November 2015.
Pricing for the Alfa Romeo 4C Spider is still unconfirmed. Expect it to be dearer than the hard-top model, which starts at $89,000 plus on-road costs.
“The all-new 4C Spider builds on Alfa Romeo’s proud heritage of motorsport success and cutting-edge technology, offering an open-air driving experience that is pure excitement,” said Fiat Chrysler Automobiles Australia's president and CEO, Pat Dougherty.
“A true convertible supercar, the 4C Spider delivers open-topped thrills without rival.”
