The Alfa Romeo 4C Spider Design Preview makes its world début at the 2014 Geneva Motor Show, previewing a new model scheduled to go into production in early 2015.
The Alfa Romeo 4C Spider Design Preview 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.
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 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 60kg.
Carbon fibre 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 centre 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 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-aluminium, 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 62mph takes just 4.5 seconds and top speed is in excess of 155mph.
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.
