Ah, I wondered how long this would take.
Doesn't matter that 80% of 1-Series owners don't even know their car is RWD, because even BMWs that nobody here would ever buy even if it was RWD and despite the entire rest of the BMW range still being RWD should still be RWD because they say so.
Seriously, some people here have no clue about the motor industry.
Making the 1-Series GT RWD would be utterly pointless. It has zero benefit for the sort of people the car is aimed at, but plenty of disadvantages. It also doesn't matter because most modern BMWs are set up to understeer anyway and their current FWD offering, the MINI, actually understeers less than something like a current 1-Series...
