1915 Cadillac V-8 Touring Car

At a time when most American carmakers used four-cylinder engines, Cadillac boldly introduced the first high-production V-8 in its 1915 Type 51 model. The larger engine produced a smoother ride, and its technical sophistication furthered Cadillac's reputation for quality engineering. The company built just over 13,000 automobiles that year, and seven-passenger touring cars like this one sold for $1,975.
