Have you ever wanted to see what would happen to a smart car hit by a wrecking ball? UK television viewers and visitors to the campaign’s microsite will find out in smart‘s new ad campaign, which starts this Sunday. The ad, titled “Wrecking Ball,” shows a helmet-less driver in a silver smart backing up into a construction site and then being hit by a wrecking ball moving at 25 mph. The steel tridion safety cell may have protected the stunt driver in this commercial, but we wonder what the results would have been had the wrecking ball came from the side. In U.S. crash tests, the smart car passed NHTSA crash tests with results ranging from fair to excellent. An ad called “Space” challenges people’s perception of the smart’s interior capacity. Smart gives Web site viewers a chance to guess which item will fit into the back of the car — from a piano to a handbag to a tumble dryer — before two guys lift the item into the car and drive away. “Fuel Efficiency” points out how far a smart car can travel on one tank of gas: from London to Edinburgh. We’re not sure how comfortable that 433-mile drive would be, but if you’d like to get more about the campaign, head to www.truthaboutsmart.co.uk.
