'''Grofri''' was a brand of cars manufactured in [[Austria]] from 1921 to 1931 (1924 to 1927 under licence from the French [[Amilcar]]). [[Sidevalve|SV]] 903&nbsp;cc or 1074&nbsp;cc four-cylinder engines were used in these sporting [[cyclecar]]s. Racing versions were also made, some of them with [[Roots type supercharger|Roots]] [[supercharger]]s.
