Brixia-Zust (originally Brixia-Züst) was an Italian car manufacturer founded by engineer Roberto Züst, owner of Zust company of Milan. The affiliated company was situated in Brescia, Northern Italy. (Brixia is the antique Latin for Brescia.) These companies are often confused. The company made racing cars that participated in Targa Florio, an open road race in Sicily.
The most interesting model was the 10 hp in 1909, propelled by a three-cylinder 1495 cc engine. Car production ended—due to financial difficulties—in 1912. From 1918, when Officine Meccaniche took over the Zust company, the Brescia facilities were used.
