2025 INFINITI QX80 vs 2025 Mercedes-Benz Amg Gt

$82,450 · SUV

$101,100 · Wagon

Comparison Overview

The age-old question for luxury buyers often boils down to outright presence versus sophisticated efficiency. Comparing the 2025 INFINITI QX80 ($82,450 MSRP) and the 2025 Mercedes-Benz AMG GT Wagon ($101,100 MSRP) highlights a major divide in approach. The QX80 brings significant bulk and power, standing 211.2 inches long and delivering a robust 450 hp and 516 lb-ft of torque. This raw capability comes at the cost of fuel economy, netting only 18 combined MPG, and it requires premium fuel. Conversely, the sleeker AMG GT Wagon, while notably less powerful at 362 hp, offers better efficiency at 21 combined MPG and features standard All-Wheel Drive. The $18,650 price gap is substantial, yet buyers must weigh the QX80's larger 22 cu ft cargo area against the AMG GT's more agile proportions.
