2025 Alfa Romeo Stelvio vs 2025 Mercedes-Benz GLC-Class
Comparison Overview
Choosing between the 2025 Alfa Romeo Stelvio and the 2025 Mercedes-Benz GLC-Class often boils down to prioritizing Italian flair versus German refinement in this luxury crossover segment. You're looking at similar price tags, with the Stelvio starting at $48,995 and the GLC-Class at $49,250. The Alfa offers a punchier performance sheet, delivering 280 horsepower and 306 lb-ft of torque compared to the Mercedes' 255 hp and 295 lb-ft. However, that extra power comes at an efficiency cost: the Stelvio achieves a combined 24 MPG, while the GLC-Class stretches to 27 MPG combined, benefiting from slightly better city mileage (24 MPG vs. Stelvio's 22 MPG). The Mercedes is also longer by 1.1 inches and offers significantly more usable space, boasting 21.9 cu ft of cargo capacity versus the Stelvio's 18.5 cu ft. Both require premium fuel, but the Stelvio’s driving experience might feel sportier despite the GLC's marginally taller stature at 66.0 inches versus 64.6 inches.
