The Alfa Romeo 4C Spider concept has been unveiled at the Geneva Motor Show,
previewing a new model scheduled to enter production next year. Designed by
the Alfa Romeo Style center, the Alfa Romeo 4C Spider concept takes full
advantage of the ultra-rigid construction and distinctive design of the coupé to
produce a Spider in the truest sense of the Alfa Romeo tradition - a car that
brings the driving experience into even sharper focus by allowing the sounds and
sensations of performance to fill the cabin and stir the driver's soul still
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 fiber 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. As a result, the additional weight of the open-top transformation has been limited to approximately 132 lb (60 kg).
The purposeful stance and stunning form of the Alfa Romeo 4C Spider has been evolved to ensure the highest levels of aerodynamic efficiency and downforce, resulting in impressive high-speed stability, while at the same time minimizing the open-top air turbulence in the passenger compartment.
Apart from allowing the driver to connect even more closely with their surroundings, bestowing the Spider treatment on the Alfa Romeo 4C also allows the world to get a better view of what is a truly special and unique interior. Carbon fiber dominates the cabin, but not as a decorative afterthought - the monocoque of the 4C Spider Design Preview is constructed entirely from this distinctive material and is clearly visible in the center console, door sills and rear bulkhead, for example.
The Alfa Romeo 4C Spider Design Preview also debuts a new dual-stage central exhaust system with titanium and carbon tailpipes by Akrapovic, a company which produces competition exhaust systems for numerous motorcycle classes including Moto GP, Superbike, Supersport, Motocross and Enduro. A key feature of the new exhaust is an electrically-operated valve system which can improve performance and enhance the exhaust note at the push of a wirelessly-linked button.
Powered by Alfa Romeo's new four-cylinder, all-aluminum, 1750 Turbo Petrol engine, which drives the rear wheels via a six-speed, dual dry-clutch Alfa TCT transmission, the 4C Spider's performance is all but identical to that of the hardtop Alfa Romeo 4C. 0 to 60 mph takes just 4.5 seconds and top speed is in excess of 155 mph. In addition, the outstanding deceleration and lateral acceleration performance, and the balanced 40:60 front-to-rear weight distribution, remain unaffected by the evolution from coupé to Spider.
Complementing its show-stopping presence, new carbon fiber clamshell headlights have been fitted to the Alfa Romeo 4C Spider Design Preview, as have new alloy wheels which have been milled from solid aluminum blocks and shod with bespoke Pirelli tires. Finished in three-layer gloss white, which helps emphasize the car's beautifully sculpted shape and masterfully resolved surfaces, the Alfa Romeo 4C Spider concept is undoubtedly a car that stirs emotions.
