You can Look at the BMW i8 as a what if?
What if future legislation destroyed the sports car as we know it?
A car like the i8 would be the next logical step to find a solution in order to stay on the road. Sustainability in a Sports car has never been heard of before but we are in a new world where sustainability in a sports car is becoming a priority.
Perhaps in a dystopian future the people will be driving i8s and craving Soylent Green.
BMWi and BMW M are sandwiched between BMW but you will not see an M i8 crossover between the brands. But you will see application of BMWi tech such as CFRP applied in BMW M and BMW models and Rolls-Royce.
