The BMW 1er being FWD, the BMW 4er having grew alot in size, it looks like the new 2er is based on Z4/Supra. BMW will give the new 2er a coupe design with lower glasshouse and higher belt line instead of the 2 door sedan look. It will then be very close to weight of Supra/Z4, lighter and more compact than 4er, have 2 more seats than Z4/Supra, and get all the engines and manual from the M4. The Supra will be dead, not much lighter, not more practical, and no manual, no M engine, more expensive for what you get.
Lesson: never make business with Germans if you are not German or US government. They always win.
Must be the reason Toyota -- if rumors are true -- is making their own Supra A100.
Looks like TMC's strategy is to go out with a bang before HEVs/PHEVs/BEVs/FCEVs really take over. They might lose some money in the short term, but that long image that will not be possible to be replicated in future will be priceless. Everyone will remember BMW had no supercar.
