Aerodynamics

According to Scientific Gems:

Frontal Area0.9125 m2
Drag Coefficient0.16

Note: Their predicted drag area from CFD (CD * A) was 0.146 m2, so doing the math with a CD of 0.16 gives a frontal area of 0.9125 m2. They never were able to accurately verify this, as the day they performed track testing was very windy, and they experimentally obtained CDA = 0.126 m2, which was significantly lower than their predicted value. They cite that they would've preferred to discount runs with windspeeds > 2.5 m/s in order to get accurate results.
