The Packard Twin Six was first introduced for the 1916 model year. This new model was named for its V12 engine, which featured twin lines of six cylinders. The Twin Six helped cement Packard as one of the most respected luxury car manufacturers. The Twin Six was built in two generations. The First Generation (1916-1923) was Packard's first V12 model, while the Second Generation (1932) was the predecessor to the Packard Twelve.
