Packard Twelve Coupe Roadster
From the turn of the century through the thirties, automobile technology was advancing at a lightning pace, and Colonel Jesse Vincent certainly played a role in that advancement. By the end of production of the original Twin Six Packard, Vincent’s engine displaced 424.1 cubic inches and developed 90 horsepower. With the introduction of the new Twin Six a decade later, displacement rose a modest five percent for a total of 445.5 inches and now put out 160 horsepower! Development of the new Twin Six, renamed the Twelve in 1933, continued, and in 1935 a heartier variation was introduced, aided by aluminum heads and an increase in stroke. Now the Twelve displaced 473.3 cubic inches and put out 175 horsepower, more than enough to propel the heaviest coachwork with a full load of passengers to astonishing speeds.
This car was auctioned off by RM Auctions in October of 2011 at the Hershey Lodge, Hershey, Pennsylvania.
