The Heat Belt contains conductors woven into the fabric that can warm it up to 96 to 104 degrees Fahrenheit within minutes of the vehicle starting. It's a simple innovation for a better driving experience in the cold, but it also offers improved EV performance and safety. Staff Reporter John Irwin spoke with Harald Lutz, ZF's senior vice president responsible for the company's passive safety division, to learn how. Here are edited excerpts.
Q: How does the Heat Belt work?
A: It's a very simple thing. Isolated wires are woven, in a specific process, into the seat belt. By applying energy to those conductors, the belt gets warm.
