The big news seems to be the new tri-turbo diesel engine. Other than that, are these cars basically an M Sport package together with the BMW performance tunes? Or simply "is" cars, but with a stronger branding name?
I hope BMW settles on one clear direction and sticks with it. A few years ago they announced the "tii" line of cars, which then somehow morphed into the "is" line of cars, now the M Performance... I am also concerned that this will signal a massive increase in the price of the "real" M cars.
