The Terrajin is Terrazi's jet car, featured in Ridge Racer 6 and 7.
Conceptually, it succeeds the Utopia, as both are jet cars and both are classified as special machines.
In Ridge Racer 6, while it lacks outright top speed, it's compensated by a stellar acceleration thanks to its superb Rocket Start abilities. The trait is carried on to Ridge Racer 7, with the addition of having large nitrous tanks that makes this car has a long Ultimate Charge duration.
- Like its elder sister, the Terrazi Utopia, the Terrajin is the only distinct rocket car in the Ridge Racer series; and it's rocket thrusters tend to light up when mobile like a spaceship. Both have the sound of an ear piercing jet engine.
- This special machine in RR6 and RR7 has the most prolonged ultimate charge out of any other special car; including the Monstrous.
