In essence, the limited-edition Giulia GTA and the more extreme GTAm are lighter and even more powerful versions of Alfa Romeo's Giulia Quadrifoglio.
To celebrate its upcoming 110th birthday, Alfa Romeo has resurrected the 1965 Giulia GTA (Gran Turismo Alleggerita, meaning 'Grand Touring Lightened' in English) moniker by introducing the hotter Giulia GTA and GTAm versions of the already performance-specced Giulia Quadrifoglio. While these new versions use a re-tuned (more powerful) version of the same 2.9-litre twin-turbo V6 motor as the standard Giulia Quadrifoglio, the main focus here has been on weight reduction and on the addition of advanced aerodynamic bits.
The V6 in the Giulia GTA and GTAm produces 533bhp (instead of 503bhp), giving them a 0 – 100km/h time of just 3.6 seconds. The torque figure seems to be unchanged at 600Nm. Further power delivery improvements come from an Akrapovič titanium exhaust that follows a central layout. To improve handling at high speeds, the front and rear wheel tracks have been widened by 50mm and the suspension setup is almost entirely new.
In terms of weight reduction, the Giulia GTA has lost close to 100kg over the standard car, thanks to the use of lightweight carbon-fibre in the driveshaft, front and rear wheel arches, bonnet, roof, and front bumper. Instead of regular steel, aluminium has been used for parts like the engine, doors, and suspension components, along with the use of more lightweight composite materials.
While the GTA offers a four-seat (regular seats) layout, with additional body kit consisting of a rear spoiler, splitter, and the same door panels, seats, and windows as the Giulia Quadrifoglio, the GTAm is straight-up a more hardcore two-seater version (although, both the GTA and GTAm are road-legal). The GTAm offers an active carbon-fibre front splitter and a larger rear wing (instead of a spoiler), in addition to carbon-fibre shell sports seats, a roll bar, six-point Sabelt seat belts, and Lexan polycarbonate side & rear windows, which been borrowed from the world of motorsports. The Giulia GTAm makes use of simpler door panels and inside door handles (replaced by belt-style openers).
Alfa Romeo will only make 500 units of the Giulia GTA and GTAm combined – each unit will have a production serial number.
