One of the first American carmakers, Oldsmobile was founded all the way back in 1897. It built the world’s first mass-produced car in 1902 and went under General Motors ownership in 1908. As a division of GM it slotted above Chevy and Pontiac, but below Buick and Cadillac. The brand was shutdown in 2004, but it remains famous for its groundbreaking technology and designs. Oldsmobile introduced more than 20 industry-first technologies, including the first production fully automatic transmission. It’s called the Hydra Matic and it was introduced for the 1940 model year.
