Hardcore gamers of "GTA 5 Online" will receive Cunning Stunts: Special Vehicle Circuit update this week, along with the addition of the much anticipated super car Progen GP1. But some hidden features and secret details have reportedly leaked ahead of the official release.

This most recent leak is courtesy of the prolific GTA gamer and YouTuber MrBossFTW (Ross). In his video (as found below), he revealed a slew of new features coming with the game's impending update. But first, it is noted that contrary to regular Tunables update, players need to download the Cunning Stunts: Special Vehicle Circuit on consoles and PC.

Rockstar Games will introduce 20 new stunt races to "GTA 5 Online", offering the gamers with one and a half hours of gameplay. Based on the screenshot, it appears that they will get behind the wheel of the Ruiner 2000 in daredevil stunt race called "Damned" and Rocket Voltic cars.

Apparently, the Ruiner 2000 won't feature missile launchers that could be used while driving the car in the Passive mode. According to Ross, if such is the case, it will become a death match that will steal the main objective of the speed racing event in the game.

The Cunning Stunts 2 DLC for "GTA 5 Online" will not likely add costumes and other accessory items. Rather, via its latest post at Newswire, players might see a number of classic super and sportscars particularly the Progen GP1 coming on Tuesday.

If one has to examine closely, the teaser photo for Progen GP1 shows that the car is not a three-seater but a classic two-seater that has color custumization for its interior and seats. Also, the supercar has butterfly-styled doors that suggest a resemblance with that of McLaren F1.

In addition, it will have personalized bumpers, vents, tiny hood pins and the like. The car also notably has carbon-fibre spoiler at the rear, however, it can't be customized at the Benny's Motorworks.

The Cunning Stunts: Special Vehicle Circuit is the first of 2017 updates coming for "GTA 5 Online". It is confirmed to arrive on March 14 across Xbox One, PS4 and PC platforms.
