Back in 2001 at the Geneva Motor Show, Smart introduced a quirky roadster concept with no doors, no roof and no windscreen called the Crossblade. The Fortwo Cabrio-based concept eventually went into a limited series production the following year with Smart offering a total of 2,000 cars.
Fast-forward to today, and Smart appears to be readying a spiritual successor to the Crossblade as the firm's parent company Mercedes-Benz has trademarked these designs drawings of a two-seater roadster model.
Unlike the original Crossblade, which came without doors featuring instead steel safety bars at passenger shoulder height that swing upwards with the help of a gas-operated struts, the roadster model seen in these pictures gets a conventional set of doors. It also features a larger wind deflector surrounding the driver and passenger as well as Smart's trademark Tridion Safety Cell - albeit redesigned to look like separate safety bars.
