Apparently the media and navigation systems of a high-end Mercedes now require more lines of code than a 787 Dreamliner:
Boeing’s new 787 Dreamliner, scheduled to be delivered to customers in 2010, requires about 6.5 million lines of software code to operate its avionics and onboard support systems.
…
Alfred Katzenbach, the director of information technology management at Daimler, has reportedly said that the radio and navigation system in the current S-class Mercedes-Benz requires over 20 million lines of code alone and that the car contains nearly as many ECUs as the new Airbus A380 (excluding the plane’s in-flight entertainment system).
There is a considerably more awesome car than an S-class described in Heavy Weather by Bruce Sterling, but I can’t find my copy to tell you how many lines of code that needed (I remember it was specified somewhere).
