My vector drawing of the Amilcar. Amilcar CGSS or CGSs was a sporting car made by the Amilcar company from 1926 to 1929. The second S stood for surbaisse and the car was a lowered version of the CGS. The 1074 cc four-cylinder engine from the CGS was fitted but in a slightly higher state of tune delivering around 35 bhp. 4700 were made.
