Alfa Romeo has a long history of creating race-inspired vehicles for the street. It’s why designers incorporated some of the same innovative materials and technology found in supercars. In the racing world, an efficient balance of power and weight is the key to successful racing cars. Alfa Romeo pursues the perfect balance between power and weight. Every component of every vehicle is designed and produced following this balance philosophy.
Alfa Romeo uses ultralight materials in every component. These materials are not only light but also durable, stiff and dynamically efficient. The Alfa Romeo 4C Coupe and 4C Spider begins with the solid foundation of a carbon fiber monocoque chassis - three times stronger and seven times lighter than conventional steel. Front and rear aluminum subframes combine strength with weight-saving technologies. Sheet Molded Compound (SMC) is used for the outer body and is 20% lighter and more stable than steel — and also resists corrosion.
If there’s one thing Alfa Romeo knows, it’s that lightness means nothing without power. At the heart of a 4C Coupe and 4C Spider is a 237 hp, 258 lb-ft torque turbocharged inline 4, with a top speed of 160 mph and a weight-to-power ratio of 10.4 lbs/hp. A figure that not only promises genuine supercar agility and performance—it delivers. In fact, the all-aluminum, mid-mounted engine rockets the 4C Coupe and 4C Spider from 0 to 60 in a head-snapping 4.1 seconds1. This breakthrough power plant, married to a car with a curb weight of a mere 2,465 lbs for the coupe version, creates a car capable of accelerating considerably faster than cars boasting higher horsepower. The 4C Spider is only 22 lbs heavier than the Coupe, weighing 2,487 lbs.

The all-new Giulia boasts an unmistakable identity — beneath all its beauty, materials are carefully selected to obtain near-perfect weight distribution. Optimal power-to-weight ratio is achieved through extraordinary engine performance and ultralight materials, including a carbon fiber driveshaft and the use of aluminum in its engine and suspension. It all translates to greater efficiency and driving dynamics destined to inspire awe.
