Both are beautiful. Both share the same mechanical assemblies, for example, the heart is a 2.9l V6 producing 505 horsepower, 443 lb-ft at 2500 rpm and eighth-speed A/T. And even the 50:50 front/rear weight distribution, the difference starts to spot when the price shows a difference of $ 5,155* CAD.
How to justify this price gap? First, the all-wheel-drive system is standard on the Stelvio and the Giulia only available for this version, the rear-wheel-drive. It represents an advance in terms of 0-100 acceleration by 0,2 second for the Stelvio.
As usual characteristic of the Sport Utility Vehicle (SUV), the Stelvio carries much more weight on your shoulders, around 240 Kg more. And in the end, the performance is in favor for the sedan, for example, the nineteen-seconds difference at the Nürburgring and 15 mph top speed.
However, put the differences aside, both are Alfa Romeo. They are Quadrifoglio.
