If not for the Cosmo 110S, Mazda may not have gone on to sell nearly two-million rotary-powered vehicles over the next 40 years. The Cosmo was hand built and only sold 1,519 models in total, but it was the halo vehicle from which Mazda’s later success spawned. Seeking a way to capitalize on their investment in the Wankel rotary, Mazda brought this phenomenal and, at the time, futuristic sports car to market. Produced from 1967 to 1972, the 110S initially had 110 horsepower derived from its twin-rotor motor. The series II brought 128 ponies to bear and, with them, a five-speed transmission and an improved ride. Less than ten models were ever brought to the U.S., with car collector Jay Leno owning the only remaining Cosmo stateside. Whether you drive one for its sleek looks or for its screaming 7,000-RPM redline, the Cosmo is a JDM artifact that is worth a spin.
