I played with the proportions a bit. On the rendering, the hood is longer and there’s a longer dash to axle ratio while the rear overhang is shorter.It's a nice rendering (like all your renderings).
Personally, with the long wheelbase and short overhangs, I probably prefer the fastback / hatchback / station wagon profile of the Airflow concept to the notchback profile.
Of course, the rendering lets me compare the profiles... thanks for creating and providing the rendering.
