Are you including both motors from the 70D (front and rear). The motor I have is the rear motor from the 70D AWD (two equal sized motors), which is listed as 170kw (or 259HP). Entering this information, looks like it should give ~6 secs 0-60 based on your calculator link. Cool calculator btw.
I think it might come in a little lighter than 3300 lbs. The Tesla drive unit has the advantage of being able to remove the transmission which shaves a few extra pounds.
