The title track features both untreated and vocoded vocals; the remaining tracks are purely instrumental. Kraftwerk used a Minimoog, an ARP Odyssey, an EMS Synthi AKS, a Farfisa Professional Piano and various devices of their own design and implementation, such as their famous electronic drums. The title track is intended to capture the feeling of driving on the Autobahn: from traveling through the landscape, the high-speed concentration on the fast lane, to tuning the car radio and the monotony of a long trip. The remaining tracks have a two-part structure—an introduction followed by a main section—and are loosely based around a theme of the night, beginning with twin tracks "Kometenmelodie (Comet Melody) 1 and 2" (inspired by Comet Kohoutek), then an ominous-sounding "Mitternacht" (Midnight) and the final track, "Morgenspaziergang" (Morning Stroll). This last track begins as a dawn chorus bird-song effect created by the electronic instruments, with an extended conclusion that uses a repeating variation of the melodic phrase heard in the first instrumental section of "Autobahn". Klaus Röder was not a member of the band for very long, and had left before the recording sessions were completed. The engineer Konrad Plank, who co-produced the very first couple of Kraftwerk albums, had reputedly played a large role in developing the early Kraftwerk sound. Much of the recording and all of the mixing of the work took place at his studio in Cologne. Wolfgang Flür had played with the band since late in 1973, first appearing with them on a Berlin TV performance to promote their Ralf und Florian album. On that show, he debuted the band's custom-built electronic percussion pads, and these feature heavily on the Autobahn album. The front cover of the original German album was painted by Emil Schult, a long-time collaborator of Ralf and Florian, who also co-wrote the lyrics to the song "Autobahn". The version released in the UK on the Vertigo label in 1974 had a differently designed cover, produced by the label's in-house marketing department. The rear cover of the original LP showed Hütter, Schneider, Röder and Emil Schult seated as if in the back of a car. Wolfgang Flür's head was added to the group photo (superimposed over Schult's) when it was decided that he would stay as a permanent member of the band. However, for the 2009 remaster booklet this image has been replaced by the version originally photographed.
