There was another huge auto show this year in Frankfurt, Germany. Spread out across a dozen exhibition halls covering a mile of real estate, the 65th IAA show featured wares from virtually every automaker on the planet.
Since General Motors introduced the first Hydra-Matic automatic some 70 years ago, the world has been divided between two types of drivers: those who push a clutch pedal and shift, and those who do not. But in a world where fuel economy takes up the majority of the automotive attention span, a third possibility looms: the dual-clutch transmission, or DCT.
