Lightweighting was achieved not only by using carbon fiber for the driveshaft, hood, roof, front bumper, front wheel arches and rear wheel arch inserts, but also by including other composite materials throughout the vehicle. From the motorsports industry, the polycarbonate resin Lexan was used in the side and rear window frames. There are even matte carbon inserts in the interior of the GTAm. The Giulia weighs only 3,350 pounds and accelerates from 0 to 62 mph in just 3.6 seconds thanks to 540 horsepower.  The impressive weight-to-power ratio is 6.2 lb/hp.

Only 500 Giulia GTA and GTAm models will be manufactured. Not only will the new owners receive a collectible and powerful vehicle, Alfa Romeo is also including a personalized experience package kit including a Bell helmet in special GTA livery, a full racing set by Alpinestars (race suit, gloves and shoes) and access to a specific driving course devised by the Alfa Romeo Driving Academy.
