Designing Aerodynamic Front of Intercity Bus

We are in process of designing bus,of 12.6 m x 2.5m x 3.8m. Its front should be aerodynamically curved. We will use Glass there. Can someone advise what may be the appropriate angle to ensure minimum drag and high fuel efficiency.

Look at to the Tesla semi truck for some ideas. Last I read, Musk was claiming a Cd <0.4 for its design.

Whatever you settle on will need CFD optimization at the very least until a winning configuration is found. Something to keep in mind while hatching out the design in CAD.

Good luck.
