A source of ours tipped us off today that Volkswagen will introduce a third interpretation of the Up! Concept at the 2007 L.A. Show that opens up to the public on Friday, November 16. According to our insider, the concept will be based on the 5-door Space-Up! (click here) prototype that was revealed at the 2007 Tokyo Show in mid-October. The main difference between the LA and Tokyo Show concepts concerns the powertrain as the Californian Space-Up! will use a high-tech hydrogen fuel-cell powered motor. We’ll have more on the new Space-Up! Concept later on. (Picture: Tokyo Show Space-Up!)
