Smart has unveiled two new style concepts for its ForFour at the Geneva Motor Show.

Called "cool & cosy" and "hot & tropic", the cars were designed to show how plastic body panels in their transparent or translucent state can be used on a Smart Forfour.

The translucent panels used on these style concepts mean the engine and radiator are visible under the bonnet, while tyres and wheel suspensions are on display under the wings.

Smart says there were currently no plans to put the concept into production, but a spokeswoman said they would not rule out the possibility.
