The EPA gives the 2021 Lexus LX an efficiency rating of 12 miles per gallon in the city, 16 miles per gallon highway and 14 miles per gallon combined. During my week with it I averaged 13.6 mpg.
While the cabin is full of luxurious style and it's pretty well-insulated from road and engine noise, Lexus needs a full-blown overhaul of its infotainment system.
