1947 Bigata Douze Special

Offered by RM Sotheby’s | Paris, France | January 31, 2024

This interesting contraption was built by Georges Bigata to demonstrate that you could build a fast sporting car powered by natural gas. And he did it in the late 1940s. But why? Well, because his family owned a natural gas company of course.

His starting point was his 1932 Auburn Twelve. The chassis was flipped upside down (to lower the car) and the 6.4-liter V12 was converted to run on natural gas. The aluminum body was supplied by Dassault – yes, the aircraft company. It is said to be capable of 125 mph with its three-speed manual transmission.

The car was later discovered still in the Bigata family and returned to operable condition. The current collection acquired it in 2008. The estimate is $165,000-$220,000. More info can be found here.
