Is it just me, or do you think that BMW could really never stop using this engine... I think they are tweaking it and playing with hybrid motors. The big boys like Porsche and Ferrari are doing the same, and I am sure Audi and Lamborghini will come out with motor soon that is hybrid with 8+cylinders. Its the wave of the future. No Millionaire who can afford such cars truly cares about emissions or MPG's... but it if make the companies image better to experiment with hybrids great.
I just don't see the V10's and V12s of the world going away any time soon.
