13. It made V8 engines a thing.
Cadillac’s 5.1L engine (70 hp) wasn’t the first V8 ever designed, but it was the first mass-produced, and the first to feature a coolant reservoir. It was so reliable, in fact, that the United States Government bought a couple thousand of them to shuttle officers around during World War I.
14. Leland and his son left Cadillac in 1917 and started the Lincoln Motor Company...and immediately bankrupted it.
Though Lincoln has enjoyed a great deal of success in the past 97 years, most of it was without the Lelands. A serious tax error to the tune of $4 million ($50M today) forced Leland to auction Lincoln off. Henry Ford bought the company on the cheap ($8.5 million; $117M today) in 1922, and, after waiting a few months, unceremoniously escorted the Lelands out of the building, symbolically ushering in a new era.
