Why it matters

Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.

History

Amilcar introduced the CGSS in the summer of 1926, as a lowered, shorter-wheelbase development of the 1,074 cc four-wheel-brake CGS of 1924. Conceptcarz says the CGS was built from 1924 to 1926 and the CGSS from 1926 to 1929, but its total of about 4,700 cars appears to count both models.

Identification guide

How to tell an original from a replica or later conversion.

Compared with the CGS, the CGSS has a lowered chassis, a revised camshaft, a larger sump, an improved steering box, a short wheelbase and larger brakes, with four 260 mm drums and a cast aluminium firewall; bodies were supplied by independent coachbuilders, most often boat-tail roadsters.
