What better way to commemorate the 125th anniversary of Carl Benz's first registry of a patent for motor vehicles than to create a new and revolutionary car in his honor?
Mercedes-Benz plans to unveil several new production models at the 2011 Frankfurt International Motor Show, such as the SLK Roadster and B-Class models. Their new Hydrogen-powered concept will complement their display nicely, as some photos of the mysterious model have leaked today.
