I'm not being a pessimist here, just an informed realist.
From Motor Trend interview with the head of M Gmbh:

Motor Trend: Tell me about light weight. Is the new M4 lighter than a 435i?

Friedrich Nitschke: Absolutely. We will use lightweight parts in the places where it matters, at the ends of the car and high up, and in high-rpm parts of the powertrain. A carbon fiber roof, of course, and aluminum and magnesium and carbon fiber in the crash zones. An aluminum hood, and a new carbon fiber trunk lid.
