Red Bull X1 Prototype The Red Bull X1 Prototype is a collaboration effort between Polyphony Digital and Red Bull Racing, specially aerodynamics expert Adrian Newey. The car was first hinted at the end of in the E3 2010 trailer, with Sebastien Vettel saying the car can "easily reach 400 km/h on straight away". The X1 Prototype was announced at TGS 2010, with complete pictures of the car have revealed in the November 2010 issue of Car Magazine. Sebastien Vettel drove a virtual lap on the Suzuka Circuit with the vehicle and set a world record on his first lap, clocking in at 1:11.540 (compared to the best lap time Vettel set at the 2010 F1 Japanese Grand Prix, which is 1:30.833). Adrian Newey created the car based on the idea of "If you built the fastest racing car on land, one that throws aside all rules and regulations, what would that car look like, how would it perform, and how would it feel to drive?".This is not the first time Polyphony Digital has collaborated with car manufacturers for real-life projects; the company worked with Nissan many times, namely the GT-R.SoundtrackFollowing the E3 2010 trailer, many fans of the game wanted to know the name of the song featured, yet the track was still untitled. Polyphony Digitial then decided to make a contest to find a name to the song, composed by Daiki Kasho. The winner was a fan from Argentina with "5OUL ON D!SPLAY". The intro song for the North American version is "Planetary (Go!)" by My Chemical Romance, while the theme of Gran Turismo, "Moon Over the Castle", is of course the song used for the intro of the Japanese version.Band of Skulls - "Patterns"Breakbot - "Penelope Pitstop"Calvin Harris - "I'm Not Alone (Deadmau5 Remix)"Camo & Krooked - "Climax"The Chemical Brothers - "Horse Power"Daiki Kasho - "5OUL ON D!SPLAY"DJ Fresh - "Talk Box (GT5 Edit)"Eagles of Death Metal - "I Want You So Hard (Boy's Bad News)"Emika - "Double Edge (GERM Remix)"Friendly Fires - "Hold On"Fuck Buttons - "The Lisbon Menu"The Fucking Eagles - "Gentlemen's Blues"Goose - "Words (Jester Dub) [GT5 Remix]"The Heavy - "No Time (Beats Mix)"Helsinki 78-82 - "Cruising"Hervé - "Blaze It (Reset!
