The 2025 Mercedes-Benz AMG GT wagon, priced at $101,100, offers a more engaging, slightly smaller footprint (199.0 inches long) with 362 hp and achieves a better 21 MPG combined. Conversely, the massive 2026 INFINITI QX80 starts nearly $17,350 cheaper at $83,750, leveraging its larger body (83.3 inches wide) to haul significantly more cargo, boasting 22 cu ft versus the AMG GT’s 16.1 cu ft.
