Car Moon

It's probably a PR's worst nightmare - having something going completely wrong at a press event. And that's exactly what happened to Volvo at the media presentation of the firm's new S60 saloon in Sweden this week.

See, the Swedes wanted to show journalists how the 2011 S60 sedan's new 'Collision Warning with Auto Brake' system works in action, so they catapulted a test car out of a tunnel at around 35km/h towards a parked truck.

Volvo says this about the system: "Volvo's new Collision Warning with Auto Brake automatically brakes the car if there is an imminent risk of a collision with a moving or stationary vehicle. The system starts by alerting the driver and preparing the braking system for emergency braking. If the driver does not respond despite the warning, the brakes are applied automatically."
