I would love to hear from anybody with a vehicle (old or new) which doesn't do one or both of those when you turn off the ignition switch!" I'd say that most older heavy diesel-powered vehicles run for a long, long time if you turn off the power before you hit the stop button, as the fuel injector pump sits on the engine itself, and continue to suck fuel as long as it can - not good for the pump, as the boost pump in the tank is off, so the engine might run lean, which can lead to engine overheating. So the stop button activates a shut-off valve, that electro-mechanically turns off the fuel, quickly starving the engine of fuel. The older Volvos has a switch that operates more like a car's ignition keys, first shutting off the fuel, then cutting the power, while newer ones has an arrangement like MAN's.
