I measured the current draw of my own car today (2002 1.9 TDi PD VW Golf). I also found the ignition uses 1.7A and the engine uses 4.7A, so 6.4A is the minimum current that will keep the car driving along. That equates to between 80w and 90w depending on the battery voltage. Engine RPM makes no difference.

All my current measurements and so on are here...

...if you're interested. Very similar results and quite encouraging for my alternator delete project.
