Alfa Romeo has taken the wraps off two special new versions of its Giulia Quadrifoglio, dusting off the GTA and GTAm badges in the process.

The company says it will build a total of 500 units, without revealing the production split between the two variants.

Conceived to celebrate 110 years of the Italian brand (and, of course, pay tribute to the original Alfa Romeo GTA of 1965), the new Giulia GTA features four seats while the Giulia GTAm pares things back to just two race seats, complete with a roll-bar and six-point harnesses.

Both variants, though, draw their urge from an updated version of the twin-turbo 2,9-litre V6 already used by the Giulia Quadrifoglio (as well as the Stelvio Quadrifoglio). In the GTA and GTAm, however, peak power has been hiked from 375 kW to 397 kW.

With the Giulia GTA, Alfa Romeo says its engineers worked to improve the aerodynamics (increasing downforce) and handling “but above all to reduce the weight”. The GTAm, meanwhile, gains a larger front splitter and a carbon-fibre wing.

Both versions boast an Akrapovič titanium central exhaust system as well as new 20-inch centre-lock wheels. The company has furthermore widened the front and rear tracks by 50 mm and developed a new set of springs, shock absorbers and bushings for the suspension system. Inside, you’ll find swathes of Alcantara along with matte carbon-fibre inserts.

So, how else has Alfa Romeo managed to shed weight (up to 100 kg, in fact)? Well, the GTA employs carbon-fibre for its drive shaft, bonnet, roof, front bumper, front wheel arches and rear wheel-arch inserts. In the GTAm, a polycarbonate resin has been used in the side and rear window frames, further contributing to the cutting of lard.

The result? Well, Alfa says the (still road-legal) Giulia GTAm will hit 100 km/h from standstill in a mere 3,6 seconds...
