I'd say this is probably crap, I dont think any car is allowed to make a decision to just cut power. Remember the uproar the cutting out 206's caused not so long ago as they were suddenly losing power on the motorway?
The car would be downright dangerous if it did that, from what I remember you have to be able to keep running the engine till it seizes, as after all it's better to have a cheap seized engine than a smeared car on the motorway (hugely expensive when you block the motorway doing that.)
