Well yes, of course. Not just talking about cars, but common sense would be to take what was previously learned and apply and improve upon on it. What I was trying to said is that OP (before threads were merged) seems to be presenting the fan made renderings as Toyota and BMW getting together...
Isn't the new 6 really just the renamed 8 series coupe? Which is reportedly getting the axe after it finishes it production run.

It sounds like they are wrapping up production on the current gen.
