Cadillac is developing new safety technology that will debut in its two new sedans, the 2013 ATS and XTS, which will both go on sale later this year. In a press release, Cadillac says the new safety suite will include a network of cameras and sensors, as well as a new safety alert seat, which is essentially a seat that vibrates to alert the driver of a possible collision.

According to Cadillac, the safety alert seat “generates vibrating pulse patterns on the left and/or right side of the lower bolster to alert the driver of potential dangers, such as drifting from a traffic lane or toward nearby objects while parking. Threats from the front and rear trigger pulses on both sides of the seat.”

The safety alert seat is part of two safety technology packages that will be optional on the 2013 ATS and XTS, as well as the revised 2013 Cadillac SRX. “The Driver Awareness Package will debut with the launch of the XTS in the spring and offers the seat, Forward Collision Alert, Lane Departure Warning, Side Blind Zone Alert and Rear Cross Traffic Alert, writes Autoblog. “In the fall, Cadillac will begin offering the Driver Assist Package, which adds Adaptive Cruise Control, Front and Rear Automatic Braking, and Automatic Collision Preparation.”

Vehicle safety technology that employs systems of sensors and audible/visible alerts is not new to the industry. Many luxury automakers, including Volvo, Lexus and Infiniti, already offer similar safety technology packages. The vibrating driver seat is new to the industry, and Car and Driver recently had the chance to experience it firsthand. “Overall, the seat-shaker concept works well and is far less annoying than an array of seizure-inducing beeps and flashes,” writes Car and Driver. “It is also helpful for drivers who might not hear warning beeps due to hearing loss or competing noises.”

The 2013 Cadillac XTS and ATS go on sale this spring and summer, respectively. The XTS is Cadillac’s new luxury large car that will sit atop the automaker’s lineup, and is replacing the DTS and STS sedans. The ATS is Cadillac’s new entry-level sports sedan that will compete with upscale midsize cars like the BMW 3-Series and Infiniti G. Pricing for both vehicles and the cost of the safety option packages has yet to be announced.
