Frequently Asked Questions

Common questions about comparing the 2025 Audi SQ7 and 2026 INFINITI QX80.

Does the drivetrain difference affect performance expectations between the SQ7 and QX80?

Yes, the Audi SQ7 features standard all-wheel drive (AWD) paired with its higher 500 hp engine, generally offering more immediate and assured handling. The INFINITI QX80 comes standard with rear-wheel drive (RWD) and less power (450 hp), suggesting a performance bias favoring the SQ7 despite the QX80's larger frame.

Which vehicle is physically larger for driver comfort and cargo?

The 2026 INFINITI QX80 is significantly larger across the board, measuring 211.2 inches long and 76.6 inches high compared to the SQ7's 199.6 inches length and 68.5 inches height. This size difference translates directly to the QX80’s much larger 22 cu ft cargo area.

How does the fuel economy compare given that both require premium gasoline?

The QX80 achieves 18 combined MPG (16 city/20 highway), which is negligibly better than the SQ7's 17 combined MPG (15 city/21 highway). Although the SQ7 offers slightly better highway efficiency, the primary factor for both is the mandatory use of premium fuel.

What is the horsepower deficit of the QX80 compared to the SQ7?

The 2026 INFINITI QX80 produces 450 horsepower, resulting in a 50 horsepower deficit when measured against the 2025 Audi SQ7's output of 500 horsepower. This translates to a 56 lb-ft torque difference as well (516 vs. 568 lb-ft).

Is the $7,050 price difference justified by the QX80's specifications?

For buyers prioritizing space and initial cost, the $7,050 savings make the QX80 highly competitive, especially considering it offers 7.8 cubic feet more cargo room. However, performance-focused buyers may see the SQ7's extra 50 horsepower and AWD system as justifying the higher $90,800 MSRP.

Do the transmissions differ significantly between these two luxury SUVs?

Yes, the Audi SQ7 utilizes an 8-speed shiftable automatic transmission, whereas the INFINITI QX80 is equipped with a 9-speed shiftable automatic transmission. The extra gear in the QX80 theoretically aids in closer ratio spacing or potentially highway cruising efficiency.
