The Packard Motor Company first came out the twin-six, a V-12 l-head engine in the 1916 model year after a four year run of six cylinder engines.
The company had been experimenting with airplane engines beginning in about 1914 and had turned to an ohv V-12 for more power. Engineer
Jesse G. Vincent knew that it was much safer and cheaper to test their airplane engines in racing cars. The result of Vincent’s efforts are seen here
where Bill Rader and his mechanic are about ready, (above) to go out onto the 2.5 mile Sheepshead Bay board track for two days of record setting.
We have more great photos and a press report about the record run at The Old Motor
