Does Your Car Have Ethernet?

By March 17, 2014

Follow me on:

Most newer automobiles use built-in networking technology of various kinds although few consumers realize or think much about it. In fact, so many different kinds of in-vehicle networks have been developed that the automotive industry considers it an issue to be addressed. While some folks think the whole world will eventually go wireless, some believe the next wave of automobiles may use Ethernet as their primary networking standard, and a few car models do include it now, led by BMW. Will your next car be wired for Ethernet?

hi Bradley,

Personally I would rather see wired cars that do not have any wireless capability, but I doubt that will happen.

There are several manufacturers that are currently marketing wireless networks for cars that can communicate up to 1 mile distant- car to car, car to traffic signal, etc.

Tesla and Rolls Royce can push ECU reprogramming to a car remotely, so that it is constantly up to date in its computers. They haven’t disclosed any info about distances from cell towers.

Would not an automobile have to have wireless somewhere between the car and the internet? It would require quite a long ethernet if the car itself was not wireless to the internet. Am I missing something here?
