Redline Reviews gave the 2027 Audi SQ9 Quattro a strongly positive 80/100 score, praising it as Audi's first true flagship full-size luxury SUV with class-leading performance and exceptional value. The standout strengths include its twin-turbo V8 delivering 591 horsepower and 0-60 in 3.8 seconds, its best-in-class interior space with a usable third row for full-size adults, and its $118,000 starting price delivering "RS-levels of power for S-levels of money." The main caveat is poor fuel economy at an estimated 17 MPG mixed driving, and the vehicle lacks a digital camera rearview mirror despite its otherwise cutting-edge tech. This SQ9 is ideal for luxury SUV buyers who prioritize performance, interior space, and value over fuel efficiency.
