Now that's a lot of yellow. Saab is showing another BioPower concept car at the Geneva Motor Show, this time with the help of tuner Rinspeed, which has a few tricks up its sleeve to spice up this 9-5 BioPower Wagon. Obviously, the most prominent feature on this Saab is the aforementioned screaming yellow paint--but there are other unique details. On the headlight surrounds, rearview mirrors, instrument panel you'll find a honeycomb texture that looks like something Spiderman would shoot out of his wrist. Unique, yes, but its purpose is unknown. Basically, this car will be a nice shiny piece to complement the Rinspeed eXasis and other assorted Saab BioPower vehicles that will be on display in Geneva.
