Packard's "twin-six" twelve-cylinder engine enabled the automaker to step away from the competition and establish itself as an industry leader throughout the 1910s and 1920s.

Macauley was instrumental in the company's decision to produce the powerful Rolls-Royce Merlin engine, which was a key factor in the success of the famous P-51 Mustang fighter in World War II.
Macauley resigned from Packard in 1948 after the company lost its place as the leading luxury-car maker in America to Cadillac.
