1. Different levels: RS stands for racing sport, which means it is the racing version of that car. The one with only S is the sports version. Although most of the configurations of multiple RS are the same , but RS is equivalent to an upgraded version of the former.

The addition of RS after the name is thought to be an upgrade of the model, similar to the iPhone and iPhone Plus in mobile phones. RS upgrades specifications and parameters from 2-wheel drive to 4-wheel drive.

2. Different speeds: Comparing Porsche 911GT2RS and 911GT3RS, 911GTR3RS is faster. The function of S is the same as that of RS. It is an upgrade of the model and improves the configuration of the car.

3. Different weight: GT2 RS is not the flagship of the Porsche family. It does not have the appearance of a supercar, and the frame is still a 997-generation product. However, the frame has been optimized and the weight has been reduced. The 911 Turbo S The four-wheel drive system was removed and the chassis was retuned.

Extended information

The 911 GT2 RS was the first Porsche road car to use steel ball joints at all chassis connections, but the mass of the elastically supported engine produced disturbing movements. The accuracy of this configuration may be affected, so the 911 GT2 RS uses dynamic engine mounts.

During acceleration under full load, dynamic engine mounting reduces vertical vibration of the engine, resulting in more even and greater drive force on the rear axle, while improving traction and acceleration. If you choose a softer driving style, the dynamic engine mounts soften, thereby improving driving comfort.
