The Sound Racer is a plug-in gizmo that delivers a crisp bellowing V8 engine sound through your stereo speakers to make your sorrowful little Trabant sound like Michael Schumacher’s shopping trolley. By some astounding feat of magic, once you’ve plugged the thing into your cigar lighter socket, it will determine your engine revs and ‘match it with just the right V8 sound.’

The people that should really think about using this puppy are electric and hybrid car owners, so they can warn little old ladies they’re coming, instead of mowing them down at the crossing with a silky swoosh. Oh and it’s also a standard FM transmitter for MP3 players. Groowwwwll…. $49.95.
