The carbon fibre is the most high-tech material in automotive engineering. The chassis of Alfa Romeo 4C Coupé – weighing only 65 kilograms – is a single carbon fibre body. The crankcase and the front and rear frames are made of aluminum, combining solidity and extreme light weight.
The outer body is made of SMC composite, a low-density material that combines lightness (it’s 20% lighter than steel) and dimensional stability comparable to steel and superior to aluminum.
With its mid-engine configuration and extremely sophisticated suspension layout (superimposed wishbone up front, evolved McPherson on the rear), the 4C is perfectly balanced and masters the road at any speed. The powerful braking system, with self-ventilating perforated discs and Brembo calipers on the front wheels, allows the 4C to stop from 100 km/h to 0 in only 36 metres.
Furthermore, Alfa Romeo 4C fits different diameter tyres on the front and rear, to ensure perfect grip on all types of roads and in any weather.
The total dry weight of the car is only 895 kilograms; this is why Alfa Romeo 4C has one of the lowest weight/power ratio: less than 4 kg/hp. With the comeback of rear-wheel drive configuration, 4C secures a great driving experience and an unmistakable racing feel.
