$96,550 · SUV

$99,990 · Crossover

Comparison Overview

Deciding between ultimate brute force and refined efficiency in the electric SUV segment is tough, and these two heavy hitters certainly challenge buyers. If sheer, neck-snapping power is your top priority, the 2025 GMC HUMMER EV SUV dominates with a massive 830 hp output versus the 2026 Tesla Model X's 670 hp. However, the Model X counters with superior efficiency, boasting a 352-mile electric range compared to the Hummer’s 315 miles, which is crucial for longer trips. Dimensionally, the Hummer is significantly larger at 206.7 inches long and 86.5 inches wide, meaning tighter parking lots might favor the shorter, slimmer Model X (199.1 inches long). Despite having less horsepower, the Model X undercuts the Hummer EV SUV by $3,440 in starting MSRP, creating a real dilemma between raw capability and practical range/cost savings.
