How do automotive firmware engineers do their jobs?

Are you an automotive engineer? Do you design engine control module firmware? Do you know or love someone who does? How is that firmware actually written?

I'm interested in learning how automotive engineers actually perform development when they're creating the firmware that runs on a car's ECU. I've got a background in software development and am familiar with drafting specifications and turning them into a delivered product. I've also got some background in embedded systems programming and a know a bit about controls. That is, I know enough to know just how complex something like a car's ECM can be given the huge number of variables involved.
So how do they do it? I can't imagine that there's a team of programmers sitting around hacking Erlang or C... right? I've played with MATLAB and Simulink, and know that you can somehow turn rigorous simulations into code but my impression is that it's not easy or straightforward. Is that what they do? What tools and techniques are the current state of the art at somewhere like Siemens or Bosch or Toyota?
