The trio sitting side by side on the main gallery on the second floor.
BAT 5 dramatic rear glass complements the fins and helps it achieve a Cd of 0.23.
1953 BAT 5 front end would look right at home in a caped crusader comic.
1954 BAT 7 was a bit more aerodynamic at Cd 0.19. It is also my favorite of the three.
BAT 7 fins the most dramatic in my opinion.
BAT 9 - Last in the series wears more conventional styling.
BAT 9 fins show a bit more restraint than it's predecessors.
One last look at the evolution of a concept.
