That 18th place finish was unique because it was wheeled by noted Packard driver Joe Boyer who had a number of open wheel accomplishments. Rolls-Royce did not manage its incredible overall production numbersagain, greater than those achieved by Packard, albeit at multiple plantsby adhering to its prewar manufacturing methods: It did so by mechanizing. It is larger, lighter-per-horsepower and has more parts than the automobile engine. Packard-powered boats were consistent winners in the Gold Cup series.
