The Volt is more software and code than anything else. The car, which GM hopes will give it an edge on rivals, has 100 electronic controllers, 10 million lines of software code and its own IP address.

GM is one of three partners developing SDVerse, a ‘matchmaking’ platform of sorts between buyers and sellers of embedded automotive software.

General Motors needed serious software engineering to manage the innards of the Chevy Volt and bring the electric car from the concept to reality. For that, the automaker turned to IBM for help.

GM is trimming its software teams globally by more than 1,000, possibly up to 1,500. The company says it's for efficiency, not cost cutting.
