Overview
The Stelvio Quadrifoglio shares the Bosch MED17.3.5 control strategy with the Giulia QV and offers similar tuning headroom. Because it is heavier and all-wheel drive, customers feel torque gains very clearly in the midrange. It is a strong high-ticket SUV product for AMT if the bench-access workflow is properly packaged.
