>>GM engineers at the rollout said that CUE was in development for three years, in part because it broke ground by using technologies that were previously not employed in autos. Capacitive touch, in particular, has not been used in vehicles until now because of questions over its ability to serve in "automotive grade" units.
"We had to develop a touch screen that would work in Michigan in winter and Phoenix in summer," Bly told Design News. "Others have not pursued the technology in the past, but we decided to take on the challenge." Bly added that GM's success with automotive-grade capacitive touchscreens was largely due to a cooperative effort with an unnamed supplier. Bly said that GM would reveal the name of the supplier next spring.
