Mercedes ESF 2009 Concept: Airbag Brakes?!

This is the Mercedes ESF 2009 Concept, scheduled to be officially revealed next week, it represents everything Mercedes knows about safety. Early details reveal airbags being used as emergency brakes. Wait, what?

Looking at these images, it appears that there's an airbag underneath the 2010 Mercedes S400 Hybrid-based vehicle that works along with Mercedes' Pre Safe Brakes, which are essentially an electronic crumple zone, actuating the full braking force when forward-looking radar detects that a collision will occur in .6 seconds. Those are already in use on the 2010 Mercedes E-Class sedan. The airbag is designed to complement that system, increasing the overall braking ability in these emergency situations by adding friction with the ground and raising the front of the car to compensate for brake dive. Since the system only actuates when a collision is absolutely unavoidable - .6 seconds is too quick for a human to react effectively - it doesn't compromise your ability to take evasive action or avoid the crash altogether.

There's also new airbags dropping vertically from the ceiling in the middle of the vehicle, preventing any inadvertent three-stooges head knocks and even airbags in the seatbelts, helping spread their load on the body during a crash.

On the still inflatable, but non-airbag front, the concept also gets hollow side impact beams that "inflate" with pressurized inert gas when an impact is detected, increasing their ability to absorb impact.

All of this might sound futuristic and more than a bit costly in case of an accident, but continues Mercedes' and the S-Class's tradition as safety innovators. Due to the law of diminishing returns, we can't expect many entirely new game changers like ABS brakes, the first airbags and stability control until we get cars and roads that talk to each other, but in the meantime incremental safety enhancements like these could save a few lives and reduce the severity of a few injuries. That's something Mercedes thinks its customers are prepared to pay for. [via eMercedesBenz]
