2022 Audi RS Q8 4.0 TFSI quattro: 591-hp V8 muscle wrapped in SUV practicality. It rockets from 0–60 mph in ~3.7 s with a twin-turbo V8, quattro permanent all-wheel drive and air suspension — yet still gives you luxury-SUV comfort, full seating for five, and a premium, tech-rich cabin. If you want a brutal, super-sport SUV that’s equally at home on the track or the school run, the RS Q8 bridges both worlds.
