Tesla...yeah, but not a Muscle Car.
Once again, the question.....what constitutes a "muscle car"? Some folks have set themselves as the authority on the definition but others, myself included, don't recognize their authority.
Agreed, as soon as someone ups the ante with a candidate, there is someone to cry foul by saying it's a pony car, or a sports car, a full size car or it was not made during the "musclecar era", or it doesn't fit the mold of intermediate chassis/big engine, or it's one of one, or limited production, race only, etc, etc, etc......and the OP's title, "Most powerful musclecar", most powerful meaning what..... HP#'s?, 1/4 mile time?, top speed?, most torque?
