By now you may have heard the term software defined vehicle. But what does it mean? Tesla was the first to make one. Chinese automakers like NIO and Xpeng followed quickly.

This Ottawa, Canada based company makes some of the most important real-time operating systems and software that power your car, including your digital cockpit and your advanced driver assistance systems. Think of QNX as the master plumber of software systems found in more than 230 million cars on the road today worldwide.
