The beginning of the track starts with engine reving sound effects (which ends the album version). The single version ends with a fade out (without the guitar bit). A really neat mix.

The same as the album mix with the added engine sound effects from the single version added at the beginning. Basically a mix between the single and album versions.

Starts with a vocal phased intro of band singing "I'm in love with my car" with engine sound effects and goes into the normal drum/piano intro. Phased chorus is used again at the end with the guitar/engine outro. A pretty good remix.

Hard to notice a difference between this version and the album mix. The most notable difference is Freddie's lead vocal volume is more noticable (example at 1:34). The keyboard sound seems to be a bit different as well. Nothing really special about this remix.

A pure uncut instrumental of the album track. No click track at the beginning of the song.

A slightly extended version for DVD-A only. The extra time is at the beginning with a longer "wind intro." Doesn't really add a whole lot to the song, but slightly adds to the atmosphere.

A very nice live version from the 1985 Rock In Rio concert. The track starts with some audience banter from Brian. Freddie and the crowd do a nice job of switching back and forth between verses.

From the Electronic Arts videogame, Queen: The eYe. At only 4 seconds, this is just a brief snippit of the harp intro to the album version. This is used as a sound effect in the game.
