BMW has released a new game for the iPhone and iPod Touch to show off its new Z4 Roadster. The game can be downloaded for free from Apple and it is inspired from the BMW Z4’s “An Expression of Joy” campaign where it allows players to “draw” using the wheels of their car by choosing different colors of paint so that their tyre tracks create drawings. The application offers players the chance to explore, customize, create and virtually drive the hardtop Z4 Roadster.
