"Luxury and driving comfort overwhelming others. This supremely luxury saloon that has only one in the world is this G00.
The title of Double 0, which was attached in the sense that it is unparalleled and not otherwise possible, represents the confidence of GNADE"
- Ridge Racer 6 website.
The Gnade G00 is Gnade's one-off concept car, featured in both Ridge Racer 6 and 7. According to Ridge Racer 7's description of the car, the double zeroes in the "G00" name means that there is no other car like it. Powered by a turbocharged engine that sends its power to a 7-speed transmission, this luxobarge is by no means slow, as it can reach over 200 mph. However, compared to other Special Machines, the G00 is completely average.

In Ridge Racer 7, being a Special Machine means that one cannot customize the car. It is obtainable by completing a special route (Ridge Racer 6) or, in Ridge Racer 7, by beating it in a duel.

Based on it's look as a sixteen-cylinder limousine, the car appears to be based on Cadillac Sixteen concept car.
