The taut proportions of the Giulia have evolved from a rear-wheel drive architecture which bestows the car with short overhangs, a long bonnet, muscular haunches and the longest wheelbase in its segment. In the Quadrifoglio version, the use of ultra-lightweight materials extends to other components including carbon fibre for the bonnet, roof, front splitter, rear spoiler and body inserts, as well as aluminium for the doors and wings.
Inside, the cabin design is centred around the driver with the main controls grouped together on the small steering wheel. The human-machine interface consists of two simple, user-friendly knobs for adjusting the Alfa DNA selector and the infotainment system. Premium materials, including carbon fibre and real wood, are used and depending on the trim level, a 3.5-inch or seven-inch colour instrument display offers the driver all the essential information about the car at-a-glance. Organised in four screenshots, the information on display changes according to the DNA mode selected by the driver, offering a variety of readings including lateral acceleration, fuel consumption and suggested gear shift points.
