It's an i8 Roadster finished in Portimao Blue, believed to be the only one in existence.

We knew this was coming, so we can’t say we’re surprised that BMW is bidding adieu to the i8. In fact, the plug-in hybrid sports car was supposed to reach the end of the (assembly) line in April, but its death was delayed by the coronavirus pandemic. The company had to hit the pause button on its operations at the Leipzig plant in Germany, and now that it’s up and running again, the final i8 has been assembled.
