The G35 takes premium gas and from my research it looked like it would average about 10 mpg less than the Solara. see full Infiniti G review

Currently get 25-27 highway and 21=22.5 in the city. Live in extremely mountainous terrain, so mpg would be higher in a flat area such as Nebraska or Kansas. I would have added a 6th gear and kept the power. see full Infiniti G review
