They'll have to put those dammits on the wheels like you used to have on your bike to make noise.

Or they can play a soundtrack of V-10's and V-12's while the electric cars go around the track.

Everyone said it would be the death of F1 when they eliminated the V12's and V10's - but they are still going strong running V8's. It might be tough to keep people interested in electric race cars, though.
