According to Mercedes-Benz, laying into an SLR McLaren too heavily could blow the alternator into smithereens. Well, not quite smithereens as much as a possible engine fire in the half-million-dollar supercar (who'd you think writes the press releases, Fritz Freleng?). As Mercedes points out, "A damaged alternator cannot assure sufficient voltage to supply the vehicle electrical system. If this condition occurs, the driver will first be informed of alternator damage by the instrument cluster multifunction displays indicating the shut down of some vehicle comfort features such as A/C, radio, etc. If voltage drops further, the multifunction display will indicate 'Battery/Alternator Stop Vehicle.' In that case the driver should shut off the vehicle and contact an authorized Mercedes-Benz dealer and have the vehicle towed in for repair. The dealer will improve engine compartment cooling, install a modified control unit and a new alternator. Smithereens, indeed.
