It's fantastic that you can get that mileage in a car that is inconvenient, small, terrible range. BMW didn't win anything other than an aerodynamics and weight contest.
I saw a Tesla Model S competing quite well on the 1/4 mile against Porche, Audi, and.. yeah It smoked a BMW M3 (I am assuming due to driver error). The key was it was quite a capable machine that after a full day of racing drove home and got 75 MPG on the freeway back to the drivers house.
