Power and Speed

Performance is a major highlight of both the Stelvio Quadrifoglio and the AMG GLC 63. Both of these vehicles look the part, and have ample power to back it up.

But look a little bit closer and you’ll see that the Stelvio Quadrifoglio edges out the AMG GLC 63 in anumber of pwer points. One of the most compelling: The 2018 Stelvio Quadrifoglio gets 505 horsepower, comparaed to the 469 output of the 2018 AMG GLC 63 Coupe. Additionally, this Alfa Romeo model can reach a mind boggling top speed of 176 mph, compared to a top speed of 155 mph in the Mercedes-Benz model. And the Stelvio Quadrifoglio utilizes dual-clutch torque vectoring, while the AMG GLC 63 has a mechanical limited slip rear differential.

Interior Accommodations

Premium materials and cutting-edge features are a must on any luxury vehicle, and many of them are present and accounted for in both the Stelvio Quadrifoglio and the AMG GLC 63. Their cabins are designed for both form and function, with easy-to-access controls, comfort-oriented seats, safety features, and tons of top-notch technology equipment.

Still, you might find the Mercedes-Benz model lacking in this comparison, as it is notably not equipped standard with the uber-popular Apple CarPlay and Android Auto features you would expect in a vehicle of this class. These two features come standard in the Stelvio Quadrifoglio.

Exterior Style

Sure, look aren’t everything, but there is a particular panache you’re after when you’re buying a luxury performance vehicle. And while beauty is in the eye of the beholder, the Stelvio Quadrifoglio nevertheless stands out more boldly and distintively than its Mercedes-Benz competitor. With Italian-bred racing heritage at its core, the Stelvio Quadrifoglio showcases a sense of power and speed in its dynamic and striking exterior design. Meanwhile, the AMG GLC63 Coupe struggles to find its identity – and comes off looking rather bland by comparison.
