Leo DiCaprio -- First Dibs On Ultra-Rare Hybrid

After years of hype, Leonardo DiCaprio finally got his hands on the most highly-anticipated hybrid car ... maybe EVER ... the 2012 Fisker Karma.

The car -- which has a base price around $100k -- is all the rage among the top players in the green community ... and according to reports, Al Gore and Colin Powell are next in line to get a Karma.

Sure it's expensive, but the Karma is nothing compared to the world's most expensive hybrid car ... Porsche's 918 Spyder -- which will set you back an environmentally sound $845K.
