$257,000 · Crossover

$83,750 · SUV

Comparison Overview

Choosing between extreme performance and extreme value in a large luxury utility vehicle presents a real headache for buyers. Do you opt for the raw, neck-snapping capability of the 2025 Aston Martin DBX707, or the spacious luxury of the 2026 INFINITI QX80? The DBX707 boasts a staggering 697 hp, significantly outpacing the QX80's 450 hp, making it an outright performance machine wrapped in an SUV shell. However, this comes at a cost, as the Aston Martin carries an MSRP of $257,000—a massive $173,250 more than the QX80's starting price of $83,750. Surprisingly, fuel economy is neck-and-neck, with both vehicles netting a combined 17 or 18 MPG. While the Aston is slightly shorter at 198.4 inches compared to the QX80's 211.2 inches, cargo space is nearly identical at 22.3 cu ft versus 22.0 cu ft, proving that luxury performance doesn't entirely sacrifice utility.
