Comparison Overview

The battle between the 2025 INFINITI QX80 and the 2025 Lexus LX pits raw power against refined efficiency in the luxury SUV segment. The QX80 excites immediately with a commanding 450 horsepower and massive 516 lb-ft of torque, making it the performance powerhouse, despite its slightly lower combined MPG of 18. Conversely, the Lexus LX grabs attention with its standard four-wheel drive system and slightly better fuel economy at 19 MPG combined. However, the QX80 delivers significantly more performance for the dollar, boasting 41 more horsepower than the LX's 409 hp rating. The QX80's larger stature (211.2 inches long) hints at more interior volume, potentially overshadowing the LX's smaller 11 cu ft cargo space relative to the QX80’s 22 cu ft capacity. While both demand premium fuel, the substantial $23,550 price gap strongly favors the aggressively priced QX80.
