REVIEW: 2018 Infiniti QX80: “Infiniti launched the QX80’s predecessor, the QX56, when environmentalists were torching Hummers and energy experts claimed peak oil would dry out the world’s reserves within decades. During the 2004 model year, its first, gas prices crested at more than $2 per gallon, prompting more predictions that big SUVs would soon be extinct. Exactly none of that happened.” I think they mean more than $4 a gallon. But yeah. Sadly, the QX80 gets mixed marks.
