The Metro Realm is the sixth realm entered by the humans, second seen in Speed of Silence.
The realm starts in a sort of underground highway with the cars entering into head on traffic. If one survives the onsluaght of cars (or finds a way to other lanes) they will emerge out onto an open highway leading up to a black and yellow city. One has the option of getting off the highway and entering a urban maze while avoiding Semi-trucks attempting to kill you, or stay on the highway. Many buildings can be seen with the Wheel of Power insignia.

- An error occurs at the end of the realm, it goes as follows: Taro is the first to reach the end of the realm, before he wins he is attacked and stopped by an RD-02 and A Silencer posing as Kurt. However, the real Kurt is the first to arrive back at the AcceleDrome. After Mark and Tork's argument Kurt states a drone must have gotten to the end of the track first. However, Taro's story contradicts this, saying he saw Kurt enter the portal first. Since that was a Silencer and not Kurt, this means Kurt would have had to pass Taro in order to be the first out of the realm, however, Taro does not claim to see two Kurts.
- This is the first realm the Silencerz win. This is also the first of many times Taro is cheated of victory by the Silencerz.
- Monkey drives Spine Buster instead of Rollin' Thunder because Nolo smashed it's windshield.
- Karma uses the Cavern Realm Accelecharger, meaning this is the first time a Teku member uses that Accelcharger.
- If one looks closely at the night stand behind Monkey when he falls out of bed, you can see a picture of Vert's mom for some reason.
- Both Synkro and Chicane are revealed to have Jump Jets in this realm.
- Oddly enough, in the Metro Realm's promotional image, both Synkro and High Voltage are seen. This cannot be the case, as Synkro and High Voltage are both driven by Nolo, and High Voltage was destroyed prior to the Realm's entrance.
- RD-L1 is killed in this realm, after being smashed by the top of the tunnel. He does not re-appear for the rest of the Acceleracers series until the Ultimate Race. This may be due to the fact Gelorum has already re-activated him once and she said in the end of Ignition that if he failed again she will terminate him. However, in the Cosmic Realm, an RD-05 appears racing with other drone cars, but a driver inside is not shown. Many RD-L1's appear in the invasion of the Acceledrome, and the main one has a different voice, suggesting that Gelorum created a new RD-L1 to drive for her.
