What the car is and where it came from
The BAT is a trio of Italian concept cars: BAT 5 (1953), BAT 7 (1954), and BAT 9 (1955). They emerged from a 1953 Alfa Romeo–Bertone collaboration. Franco Scaglione designed all three.
How it works, in terms someone would actually use
The BAT cars sit on the Alfa Romeo 1900 chassis. Their bodies are shaped to reduce aerodynamic drag. Each car was built as a rolling test of airflow behaviour.
What it gets right
It isolates drag reduction as a singular design goal. The progression from BAT 5 to BAT 9 shows iterative refinement of that goal.
What it does not
It does not deliver performance data, driver feedback, or production intent. It is not a prototype for a production model.
What it changed
It demonstrated that extreme aerodynamic form could be explored in road-car packaging without altering mechanical layout.
Who it is for, and who it is not
It is for designers, engineers, and historians focused on mid-century automotive research. It is not for collectors seeking drivable classics or buyers seeking usability.
Is it worth your time
Yes—if you care about how design solves physics problems, not just how cars look.
