The new Giulia GTA is inspired by its 1965 namesake, the ‘Gran Turismo Alleggerita’, developed by Autodelta and based on the Giulia Sprint GT. Alleggerita is Italian for “lightened”.
The new 4-seat GTA is based on the Giulia Quadrifoglio and is fitted with a more powerful version of the Alfa Romeo 2.9-litre V6 Bi-Turbo engine, now with 540hp.
Extensive use of ultra-light materials gives a weight saving of 100kg compared to the Giulia Quadrifoglio, giving it a best-in-class power-to-weight ratio of 2.82 kg/hp
A GTAm variant will also be available, a version of the GTA with two racing seats, roll-bar and six-point seat belts.
Only 500 units of the Giulia GTA and GTAm will be available.
On the Giulia GTA, the Alfa Romeo engineers have worked to improve the aerodynamics and handling as well as to reduce the weight.
The active aerodynamics were specifically increased the downforce. These solutions contain technical know-how that comes directly from Formula 1, thanks to the synergy with Sauber Engineering and the use of the Sauber Aerokit. The same task is assigned to the side skirts, the specific rear spoiler and the active front splitter.
The titanium Akrapovič central exhaust system, integrated in the carbon fibre rear diffuser, is also new, as are the 20-inch centre lock wheels. Handling at high speeds has been improved by widening the front and rear wheel tracks by 50mm and developing a new set of springs, shock absorbers and bushings for the suspension systems.
On the GTAm, the aerodynamic front has been optimised by adding a larger front splitter and a real carbon-fibre rear wing, which ensure a perfectly balanced load at high speeds.
In terms of performance, the Alfa Romeo 2.9-litre V6 Bi-Turbo engine, made entirely of aluminium and capable of unleashing no less than 510hp in the standard configuration, reaches an output of 540hp in the Giulia GTA.
A new Akrapovič central exhaust system, in titanium and gives the car an unmistakable sound.
An Alcantara trimmed dashboard, door panels, glove compartment, side pillars and the central trim on the seats, characterise the interior.
Alcantara is used even more extensively in the GTAm version, where the rear bench has been removed, leaving room for a fully upholstered ‘basin’, with specific mouldings designed to hold helmets and a fire extinguisher.
The new matt carbon-fibre inserts give the interior a distinctive technical and aesthetic elegance. In the new GTAm, the interior is unique in that it features a roll-bar, no door panels or rear seats and the door is opened with a belt in place of the handle, another touch inspired by the racing world.
The car has been lightened by 100kg. To achieve this the GTA uses lightweight materials such as carbon fibre for the drive shaft, bonnet, roof, front bumper, front wheel arches and rear wheel arch inserts and the shell of the sports seats with six-point Sabelt seat belts in the GTAm. Aluminium has been used in the engine, doors and suspension systems and various other composite materials have been used throughout.
In the GTAm, Lexan – a unique polycarbonate resin which comes straight from the world of motorsport – has been used in the side and rear window frames, further contributing to the weight reduction.
The result is a weight of around 1,520kg which, combined with the increase in output to 540hp, brings the power-to-weight ratio to 2.82 kg/hp, making the Giulia GTAm capable of delivering extraordinary performance.
Its acceleration from zero to 100kph, with the Launch Control system, is just 3.6 seconds. The Giulia GTAm is a two-seater configuration that is road legal, with front splitter and larger visible rear wing in carbon.
In the GTA trim, with the same output, the Giulia offers four seats, no rear roll-bar, a spoiler and splitter optimised for daily use and the same door panels, seats and windows as those of the Giulia Quadrifoglio. The result is akin to a supercar for everyday use.
