If you plan on going for a barbecue that puts itself at the top of the food chain then I believe you’ve hit the peak. The Summit series is where Weber puts all of their best ideas and quality into one monstrous grill.
The E470 boasts a total of over 85,000 BTUs with all of its burners. You get 4 primary stainless steel burners, 1 booster burner for searing capabilities, a rear burner, a side burner, and finally, a smoker burner used solely for the built-in smoker box. Does it get much hotter than that? I mean, if you somehow manage to set the barbecue itself on fire... then yes, it can probably get hotter than that.
