Video: Alfa Romeo Giulia GTA put through its paces by Kimi Raikkonen and Antonio Giovinazzi

Alfa Romeo’s wild Giulia GTA and GTAm monster sedans have been put to the track test by F1 drivers Kimi Raikkonen and Antonio Giovinazzi, at the famous Balocco Proving Ground – home to Alfa Romeo sports car testing since the 1960s.

Although partly a valuable promotional opportunity, inviting the brand’s motorsport representatives to test the new hero Giulias is an important part of the development process.

Both drivers worked with the Autodelta and Sauber engineers to lock down the sedans’ power, response and aerodynamics – the latter being a specific responsibility of the Sauber Engineering team.

Describing the carbon-fibre lightweighting and aerodynamic components developed for the GTA models by Sauber, Raikkonen said: “I find them a perfect mix of everyday use and track use”.

Revealed in March, the Gran Turismo Alleggerita and Gran Turismo Alleggerita Modificata models will be built to a limited run of just 500 units – none of which are expected to come to Australia. At least, none that the brand has been prepared to announce, though you can never know what a wealthy collector will do.

Power in both is provided by a 402kW Autodelta-fettled tune of the Giulia Quadrifoglio‘s 2.9-litre bi-turbo V6 petrol engine, which delivers 375kW in its standard form. Torque numbers are still to be revealed, but the 600Nm of twist offered by the regular Giulia Q is nothing to shrug at.

Thanks to its multitude of tweaks and enhancements, the GTAm claims a 0-100km/h time of 3.6 seconds.
