The 2015 BMW i8 has been available in the U.S. since August, but it wasn't until more recently that the i8 configurator came online.
Configuring the i8 is a simple process: choose a world (Mega, Giga, Terra or Pure Impulse), select a color and interior, choose your wheels and you're all set.
There are zero stand alone options on the BMW i8. So, basically you pick the world that offers the options you'd like on your i8.
Maxed out, a BMW i8 goes from a base price of $136,650 to $147,450.
