A new GTA model wouldn’t be true to its name without some exotic weight-saving measures, and they are present in abundance. Along with most of the additional body parts, the hood, front fenders, and roof are all carbon fiber.
At 100 kg, the overall weight gain is not as great as expected. Yet the 1580 kg Giulia GTA is lighter than the Audi RS5 (147 kg), the BMW M3 Competition (170 kg) and the Mercedes-AMG C63 S 4Matic + (also 170 kg).
The more hardcore Giulia GTAm takes it a step further with lightweight plastic rear door panels, polycarbonate rear windows, Sabelt carbon fiber shell front seats, nylon door handles in place of the standard handles and removal of the rear seats. Even with the addition of a rear roll cage, Alfa Romeo claims these measures reduce the curb weight by an additional 40 kg, bringing it down to 1,540 kg.
Under the lightweight hood, the Giulia GTA uses the same Ferrari-designed and developed 2.9-liter V6 turbocharged petrol engine as the Giulia Quadrifoglio. Power increased from 30hp to 533hp thanks to the adoption of new connecting rods, additional oil injectors, an overhauled oil cooler, changes to the software controlling the turbocharger and, most obvious of all , an Akrapovic titanium exhaust system with two centrally mounted tailpipes. Torque, however, remains the same at 443 lb-ft.
Drive is sent to the rear wheels via a ZF-produced eight-speed gearbox and electronically controlled differential, both of which receive unique mapping specific to the new Giulia headliner model.
Other changes are focused on the chassis of the Giulia GTA. It gets 25mm wider front and 50mm wider rear tracks, as well as new mapping for electromechanical steering and lowered double wishbone front suspension and multi-link rear suspension with springs and struts. Firmer shocks as well as -roll bars, among other detailed modifications. Custom 20-inch forged alloy rims with worn center locknut Michelin Pilot Sport Cup 2 tires, 265/30 ZR20 at the front and 285/30 ZR20 at the rear.
