On the safety side of things, the car came standard with Bosch ABS and traction control, central carbon
fiber safety cell with a steel and carbon fiber roll bar, and front and rear carbon fiber impact absorbers.
Carbon
fiber isn't necessarily replacing the metal in the 7 - Series, but acts as bracing and an energy deflector all over the
safety cell, which allows BMW to use less of the heavier steels and more lightweight aluminum throughout the car.
