GTA Online have released the fastest supercar in the car, the X80 Proto. It’s that quick that you will have to take some time to get used to the handling, power and speed of the X80 Proto.
YouTuber Broughly1322 has released a video and states that it is quicker that the T20 but it isn’t going to set the game on fire as the speed is only slightly different between the T20 and the X80 proto.
The Grotti X80 Proto was released as an update in the DLC pack Further Adventures in Finance and Felony. To buy the car youll have to have deep virtual pockets, it costs an eye watering $2.7Million.
