1923 Alvis 12/50

The 12/50 was the car that really put Alvis on the map. It featured sporting performance that put it in competition with the upper end of British sports cars. It was also an expensive car and one that was built with lasting endurance and reliability. For this reason, the 12/50 had a long production which lasted from 1923 to 1932.

One of the more memorable 12/50s was the Super Sports, with its aluminum torpedo-style body. It had a distinctive external exhaust and a tight rumble seat in the rear.

Throughout Britain, the 12/50 racked up wins in speed trails, hill climbs and racing. The cars best achievement was the an overall win at the 1923 Brooklands 200 mile race.

The 12/50 was replaced by the revolutionary Alvis FWD, which helped pioneer front wheel drive in production sports cars. Nearly 4,000 cars were built including the 12/60, with its englarged engine.
