I can answer some of this but first a bit of background. The police spec cars are built on the standard production line and then taken to the Special Vehicle Centre for conversion into a Police car. Every Swedish Police car is also converted there as are all the Swedish taxis all V70 diesels.

Standard parts are stripped out and replaced with updated parts so as you have mentioned unrated alternator and battery to support all the additional equipment to be fitted. Unrated brakes and suspension and even heavy duty alloy wheels.

The additional wiring is part of the preparation work for the apolice euipment to keep the loads and the EMC from effecting the standard Volvo equipment.

The engine Optimisation is Volvos in house upgrade to try and keep up with the BMW 530d but they never quite managed it. In theory it should have been put back to standard before the vehicle was sold. Not sure if this every happened though.
