Autobahn is the fourth studio album by German electronic music band Kraftwerk, released in November 1974 by Philips Records. The album marked several personnel changes in the band, which was initially a duo consisting of Florian Schneider and Ralf Hütter; later, the group added Klaus Röder on guitar and flute, and Wolfgang Flür on percussion. The album also completed the group's transition from the experimental krautrock style of their earlier work to an electronic pop sound consisting mostly of synthesizers and drum machines. Recording started at the group's own Kling Klang facility, but was predominantly made at Conny Plank's studio. Autobahn also includes lyrics and a new look for the group that was suggested by Emil Schult, an associate of Schneider and Hütter.
Most of the album is taken up by the 22-minute "Autobahn", featuring lyrics by Schneider, Hütter, and Schult. The song was inspired by the group's joy of driving on Germany's autobahns, and recorded music that reflected a trip emulating the sounds of a vehicle. The album's release in West Germany saw little press attention. "Autobahn" was released as a single and received airplay at a Chicago radio station, leading it to spread across the United States. In 1975, the song became an international hit and Kraftwerk's first release of their music in the US.
