If you've ever seen pictures of Alfa Romeo BAT or better, had the chance to admire them one day at Rétromobile, Bagatelle, Goodwood or Villa’Este, their shapes will have left their mark on you for life. This trio of Alfa-commissioned concepts, designed by Franco Scaglione and built by Carrozzeria Bertone in the 1950s, has one of the most iconic silhouettes in automotive history.

In the civil registry, the BAT family is called Berlina Aerodinamica Tecnica. As you also speak fluent Italian, you will have deduced the vocation of these concepts: the BAT 5 of 1953, the BAT 7 of 1954 and the BAT 9d of 1955.

It's sublime, and we can imagine the excitement that these lines may have caused in their time despite a relatively modest technical basis of Alfa Romeo 1900. Their four-cylinder 100 hp (for about 1.1 t) was enough for them. to approach the 200 km / h thanks to a Cx record (0.19 on the BAT 7).

The trio – Bertone paid homage to them in 2008 with a BAT 11 on an 8C platform – had been part of the same private collection since 1989. That year they were exhibited for the first time together at Pebble Beach, in the occasion of the visit of Nuccio Bertone, and a collector made an offer to each of the three owners. They will be put up for sale, but rest assured, they will not be separated: they are part of the same lot that RM Sotheby’s will auction on October 28.

The triptych is estimated between 14 and 20 million. In organs, that's a lot, but when you love …
