The Giulia makes extensive use of lightweight materials, including aluminum, carbonfibre, and aluminium and plastic composite. Aluminium is used to construct the suspension, doors, wings, sub-frames, and brake calipers. Carbonfibre is used for the bonnet, roof, prop shaft and front seat structures, and the composite for the rear cross-member. Further weight reduction comes from the use of carbon ceramic brakes on the Quadrifoglio Verde model.
The location of the lighter materials has also helped Alfa achieve its 50/50 weight distribution target, with major components located between the axles, and the lightest materials used at either end of the car, such as aluminum for the suspension.
The Quadrifoglio Verde’s twin-turbo 3.0-lite V6 engine is also a lightweight unit. It features cylinder deactivation and can, said Alfa, be "surprisingly fuel efficient" while still offering "fun and identity". Krief added that the Ferrari-developed unit offered "fantastic torque all through the rev range and no turbo lag in any gear". A 0-62mph time of 3.9sec has been quoted for this model, which is hooked up to a six-speed manual gearbox as standard.
The Ferrari link to the engine could prove to be significant again in the future as the rumoured base powerplant in the new Ferrari Dino model that is understood to be in development for a 2018 launch.
Alfa has yet to confirm any other launch engines for the Giulia. However, the new V6 will be one of two engines built at a new €500 million facility Termoli facility in Italy with an annual capacity of 200,000 units. The other is set to be an "advanced, high-output, four-cylinder engine developed for Alfa Romeo", which expected to be the next-generation replacement for the highly regarded 1750 TBi engine currently used in the Alfa 4C. It could produce as much as 300bhp in its highest state of tune.
Previous indications from Alfa have pointed towards an engine range that will also include four- and six-cylinder diesel engines.
Krief said the Giulia would do without “invasive” electronic systems that inhibited the rear-wheel drive driving character of the car. There will also be no autonomous driving features, Wester revealed previously, because it would not be in tune with the brand’s character.
It will, however, feature a Torque Vectoring System in the rear differential to split torque independently between the rear wheels, and a new Integrated Brake System that combines stability control with the servo brake from what Alfa claims is improved feel, responses and reduced braking distances.
An Active Aero Splitter at the front helps aid the Giulia’s aerodynamic design, and the system, like the other electronics, is controlled by Chassis Domain Control electronic ‘brain’, tasked with ensuring driving pleasure and performance for the driver.
On the Giulia's styling, Alfa design boss Lorenzo Ramacotti said the car was "not over-styled, which is very easy to do today. It can be defined with just three strokes.
"Form and function doesn't mean it's cold. It's an Alfa, an object of desire that you experience, not an ornament to look at."
The new Alfa has a wheelbase that’s claimed to be the longest in its class, but with a body that’s one of the shortest. Rear cabin space is said to be impressive, although there’s no word on boot capacity.
