100 computers and a ton of wires

Jaguar Land Rover

The typical Jaguar Land Rover car now sports more than 70 electronic control units (above), essentially embedded computers. The company's premium cars pack more than 100. They require about 5.5 million lines of code running over multiple RTOSes.

"It challenges the level of complexity in aerospace," Tomar said.

To connect all those sub-systems, the cars use 50kg of wiring (below)—enough to stretch 6km and cost $3,700. The wiring harnass weighs about as much as an adult passenger, he said.

Standard cars carry more than 100 sensors, and premium models carry more than 130, Tomar said.
