Better than a BMW M, angrier than an AMG? 2024 Alfa Romeo Giulia and Stelio QV models bring the noise

The MY23 Alfa Romeo Giulia and Stelvio QV models will arrive in Australia in December, with the Italian twins packing a new performance punch.

Both remain powered by Alfa Romeo's epic 2.9-litre V6 bi-turbo engine, good for 375kW and 600Nm, with the brand promising a sprint to 100km/h of 3.8 seconds (Stelvio QV) and 3.9 seconds (Giulia QV).

But joining the performance package for this MY23 update is the addition of an all-new mechanical limited-slip differential, which should deliver better cornering and more dialled-in handling.

It also gives the driver a more direct feeling, emphasising the vehicles’ dynamics and sportiness."

And you can add to that the specific QV Active Suspension, a performance braking system and an active front splitter (on the Giulia).
