Automatic transmission
The desire for driver convenience led to the widespread implementation of the now-popular hydraulic automatic transmission design in the 1940s, followed by the first mass-production continuously variable transmission (CVT), the "Variomatic", in 1958. Automatic transmission with manumatic (manual) gear shifting controls started to appear on mass-production cars in the early-1990s, starting with Porsche's "Tiptronic" system. Later, the computer-controlled, single-clutch, automated manual transmission, pioneered by BMW and Ferrari, began appearing on mass-production automobiles in the mid-1990s; one example is Alfa Romeo's "Selespeed", which is the same system used by Ferrari and BMW. The first mass-production dual-clutch transmission design was introduced with the 4th-generation "Volkswagen Golf R32" in 2003, with the "direct-shift gearbox".
