Model S Performance vs. RENNtech E63

I'd say comparisons against stock (from the factory including factory tuned cars like AMG) are valid but custom tuned cars are a different category. It can't beat everything of course but decent effort.

Looks to be a $15-22k upgrade to the E63 AMG so over $110,000.
 
That E63 in the video put down 630 horsepower to the wheels, so it's really a 700+ horsepower car.... the upgrade is around $4k from RENNtech....

Instant torque is a wonderful thing yet EVs in general are not popular amongst gearheads and probably never will be.
Good thing no one told all of us gearheads who modified our ICE's to be EV's, including some drag racers. Eventually someone will drop the pack out of an S and install a smaller lighter high C rate pack, and maybe tweak the max current and voltage for the inverter.
