We are soon at the end for the petorl engines.. that's why Audi are giving "maybe" the last generation RS6 with petrol 550 to sett the last RS6 as high as you can! Next gen. will maybe run on something like water.. you guys know what I mean..
So what I'm trying to say is that we are at the top.
new fuel types, new HP, -- ect.
They are going down! to Battery Size!

No.. aah. I don't know for sure
Let's wait or see - or ask the Car brands ?
