The U.S. Gold-published version for Amiga, Amstrad CPC, Atari ST and ZX Spectrum sold very well in the UK, shifting over 200,000 copies in its first two weeks of sale, during the pre-Christmas period, making it the fastest-selling game in the UK up until that time. It was the best-selling game of 1987, having sold over 250,000 copies in December 1987.
Amstrad CPC version
The Amstrad port of OutRun runs much slower than the arcade version, and lacks any sort of indicator to tell the player whether they are in low or high gear. The only in-game sound effect (or indeed sound full stop, as there is no in-game music) is a beeping noise made when the car skids around corners. There are also no crash sequences should the player make a mistake - the car is just teleported into the middle of the road. This version does, however allow the player to adjust the "traffic" (i.e. difficulty).
As a multi-load game, the Amstrad CPC version will pause between stages as the new track is loaded from disk (or cassette).
Atari ST version
Despite running on more capable hardware than some of its siblings, the Atari ST version of OutRun lacks the forks in the road and runs with a low frame rate.
Commodore 64 version
The Commodore 64 version is missing Passing Breeze from its music selection, and also lacks the splits in the road, meaning there is only one possible journey in the game.
This port is widely thought to have been rushed to market by U.S. Gold to capitalise on the holiday season of 1987.
The MSX version of the game seemingly borrows some of its graphics from the ZX Spectrum port, but the code behind it is entirely different, with less responsive controls and jerky corner sections. There are no sound effects, and the music (Magical Sound Shower) restarts whenever the player crashes.
ZX Spectrum version
The Spectrum port shares several of the same problems as the Amstrad conversion, though is slightly faster, generally more detailed and as a 128k release, also includes music (though it is not selectable - the game only contains Magical Sound Shower). Traffic can also be adjusted, however the game suffers from noticeable slowdown when too many objects on on-screen at once. There are also obvious colour limitations due to the hardware.
The ZX Spectrum version of the game was controversial, having originally appeared in popular UK Spectrum magazine Your Sinclair with far superior graphics than what was seen in the final product. U.S. Gold's attempts at brushing this off as a platform limitation were trumped by the existence of Ocean Software's Spectrum conversion of Chase H.Q., widely seen as a much more technically competent conversion. Your Sinclair subsequently gave the game a suspiciously high 8/10 rating.
