The Amilcar CGSS (or CGSs) was made by the Amilcar company from 1926 to 1929. The second S stood for surbaissé and the car was a lowered version of the CGS. The 1,074 cc four-cylinder engine was from the CGS, but in a slightly higher state of tune, delivering 35bhp. It was also available with a Cozette supercharger if more power was desired. Thus blown, a CGSS won the 1927 Monte Carlo Rally driven by Lefebvre and starting from Königsberg (today’s Kaliningrad).
The famous American dancer Isadora Duncan lost her life in a CGSS. Her fondness for flowing scarves was the cause of her death in 1927 in Nice. She was the passenger in an Amilcar CGSS when her silk scarf became entangled in the open-spoked wheels and rear axle, pulling her from the car and breaking her neck.
