Dang you got my curiosity up enough to do a few google searches.

Typical industrial 250 hp 3600 rpm motor about 2700 lb. Now this will run at 250 Hp for years non stop.

Tesla's model S 362 hp motor weighs 70 lb. Now it likely can only do that for less than a minute, before it overheats, but it doesn't need to do any more.
