We're big fans of the Fiat Panda, which manages to combine the most desirable attributes of an MPV and a 4x4 hatchback in a reliable package. It's no wonder then that Fiat has repeatedly used this platform to debut new technologies. The Fiat Panda Aria pictured here sans cover is the second generation of the eco-concept car. The original Panda Aria debuted at Frankfurt last year and featured a small-displacement two-cylinder turbocharged engine that could run on gasoline or a methane-hydrogen mix.

We'll wait for the official debut before we speculate on the powertrain of the newer Aria. [Source: Fiat]
