It's very hard to keep secrets, especially as a car manufacturer. If we have to believe the rumors, this is a scale model of the new Porsche 991 GT3 RS. The last time that the 991 GT3 RS was spotted is almost two months ago but this won't say that Porsche isn't working on this car. They were very busy with the engines of the 991 GT3 with it's production error, and that's probably why the trajectory of the 991 GT3 RS needed some more time.
When we compare this scale model with the latest spy shots we do see some similarities but we also miss some details. We miss the fenders on the side of the front bumpers and we see some extra air intakes on the front shields. Despite this, the 991 GT3 RS will definitely be a brutal car and we can now only wait until Porsche releases the first teaser or specifications of this model. We expect that the engine will produce more than 500 hp and that the engine will be attached to a PDK gearbox, they probably won't come up with a manual gearbox.
