$59,650 · Crossover

Comparison Overview

The 2025 INEOS Grenadier ignites the off-road passion with its rugged, towering stance, boasting 282 hp and massive 332 lb-ft of torque optimized for serious traversing, despite its thirsty 15 MPG combined rating. Conversely, the 2026 Mercedes-Benz GLC Coupe captivates with sleek, athletic crossover styling, offering superior efficiency at 26 MPG combined from its 255 hp engine. This comparison pits raw, boxy capability against polished, streamlined on-road grace. The Grenadier, spanning 191.2 inches long and standing a towering 80.7 inches high, is built for approach angles, not aerodynamics.
