Stardust Speedway (星くずのサーキット Hoshikuzu no Sākitto?, lit. "Stardust Circuit") is a location that appears in the Sonic the Hedgehog series. It is an urbanic region on Little Planet that was once conquered by the evil Dr. Eggman when the doctor seized the planet for his world conquest plans. It is best known for being the site of the first clash between Sonic the Hedgehog and Metal Sonic.
Stardust Speedway is a city on Little Planet, near Palmtree Panic and the Wacky Workbench. It is notable for its light colors during night. Numerous golden highways adorned with instruments, signs, gimmicks, and Time Warp signs are also found in the city, while some buildings and lights are seen in the background. Also, what appears to be a factory under construction is seen below those highways. Somewhere in the city, a Dr. Eggman-themed statue can be seen being under construction.
In the past, Stardust Speedway used to be a Greek/Roman-styled city. The highways were green and filled with vines and other types of vegetation. In addition, what appeared to be a lake was seen underneath them. There was also a dark-colored palace in the same place where the Eggman-styled statue is currently located.
When Dr. Eggman re-wrote the future to his own image, the city was the same as in the present, but it was polluted and ruined with some red storms constantly destroying the place. The highways appeared jade green due to age, and their instruments showed some signs of damage. The statue was now totally finished. A gray amusement park also appeared in some part of the city, but it does not seem to be working. After Sonic the Hedgehog re-wrote history, Stardust Speedway was no longer a city, but an amusement park, as far as the eye can see, in a bay full of lights, colors and attractions, where fun and leisure dominated the place. The highways appear in a lavender color with plaques of hearts on them. There are also many support gilders on them. The statue has also been replaced by a lavender cathedral/castle.
Stardust Speedway once used to be a Greek/Roman-styled city near a lake. Over time however, it was turned into a modern and colorful city.
Sonic the Hedgehog CD
In Sonic the Hedgehog CD, Dr. Robotnik invaded Little Planet and its regions, which included Stardust Speedway. He installed robot teleporters in the past and infested the city with Badniks. He also put some Metal Sonic holograms to terrorize the local Animals. With this, he managed to conquer the future of the planet and write history to his own image. However, the doctor's influence over time turned the city into a wasteland as a result of the constant thunderstorms caused by the pollution on the planet.
When Sonic the Hedgehog arrived into the planet, he started to get the Time Stones and re-write history in Little Planet, reverting Robotnik's effects in Stardust Speedway. After Metal Sonic kidnapped Amy Rose in Collision Chaos, Robotnik left her tied somewhere in the highways, and waited for Sonic to show himself up to rescue the girl. After Sonic arrived, fixing the future and turning it into a amusement park, Metal Sonic challenged Sonic to a race, with Amy being the end of it. The hedgehog won, destroying Metal Sonic and freeing Amy. The hedgehogs later left Stardust Speedway to defeat Robotnik in Metallic Madness. After this, Little Planet was definitely freed from Robotnik's control, leaving Stardust Speedway to have a peaceful destiny.
In the console/PC version of Sonic Generations, an incarnation of Stardust Speedway from somewhere in spacetime served as the site where Classic Metal Sonic challenged Classic Sonic to a battle. After the hedgehog won, the robot gave him a Chaos Emerald.
After the Time Eater was destroyed, Stardust Speedway was presumably restored to its proper state in the timeline.
Sonic the Hedgehog 4: Episode Metal
In Sonic the Hedgehog 4: Episode Metal, a monitor from Dr. Eggman was taken to Stardust Speedway to reactivate a not-working Metal Sonic. After the doctor succeed, he told him to return to Sonic's world, where he would repair him. No explanation has been given of why does Stardust Speedway appear in its "bad future" state when Eggman's monitor visited Little Planet.

Books and comics
In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, Stardust Speedway Zone was an area within Collision Chaos Zone - a Zone created by Dr. Ivo Robotnik and used as a trap for Sonic the Hedgehog, in which Amy Rose served as bait. In Stardust Speedway Zone, Sonic defeated Mecha Sonic during a race and saved Tails and Amy.
After the Super Genesis Wave rewrote reality, Stardust Speedway became much more similar to its game counterpart, being a Zone under Dr. Eggman's influence on Little Planet and having the same role it had in Sonic the Hedgehog CD.
