OYSTER BAY, NY -- A new war among automakers is on the verge of breaking out. The battle: safety as the key differentiator for vehicle lines.

"There are a host of cutting-edge safety systems in varying stages of development that will alter the consumer's perception of what makes for a safe vehicle," says ABI Research senior automotive analyst Robert LaGuerra. "What is interesting is that automakers disagree about how they define a safe vehicle."

LaGuerra adds that automakers are tackling the issue of safety from varying perspectives. From electronic stability control, adaptive cruise control and telematics systems, to blind-spot detection, lane-departure warning, driver monitoring, and pedestrian-based safety systems, all will be used in some combination to make for a safer vehicle.

Automakers such as Honda and Mercedes are among the first to introduce systems promoting pedestrian safety, while GM may be the first to introduce both ESC and reactionary safety systems such as OnStar as standard equipment across all its North American models.

ABI cautions that there are still issues to be overcome, including high systems costs, the ability to have on-board safety systems communicate with each other, decisions about how much control should be taken away from the driver in an emergency, plus software and processor limitations in assessing an emergency situation on a real-time basis. ABI suggests that further systems integration will not only enhance the level of safety, but help reduce overall system costs.
