I like these type of reviews. While certainly not unvarnished praise, it compares the roadster to other supercars in a no compromise sort of way. This is the next step for EV adoption where they can be compared to ICE cars directly without apologizing for the short-comings of BEVs. Similarly to what hybrids have had to go through. I imagine that in less than 10 years ICE supercars will not be able to compete with EVs performance or cost wise.
From the article:
I wonder how accurate those current numbers are and where the author got them.The Roadster Sport's AC induction motor is hand-woven with more copper than the standard car's powerplant, and it produces 40hp more and an extra 19lbft of torque as a result. If you prefer to measure such things in sheer current, the regular motor can draw 800 amps from the car's lithium ion battery at any one time; the Roadster Sport peaks at 1000 amps.
Tesla Motors - performance specs
16% higher peak power, 7% more torque, but with 25% higher peak current. Lends further credence to this: Sport vs. Non-Sport the same motor?Base: Output 248 peak horsepower (185kW) and 276 lb-ft (375 Nm) of torque. Redline at 14,000 rpm.
Sport: Output 288 peak horsepower (215kW) and 295 lb-ft (400 Nm) of torque. Redline at 14,000 rpm.

They've been mentioned in other stories recently.
That being said, I agree with Doug that the numbers as given by the article don't make sense.
When I had an overheat problem this summer, the service department swapped the PEM here at my home in Arizona. The PEM that was FedEx'd to my home was labeled a sport PEM. Neither the tech or I noticed that until he had done the swap and discovered the difference in testing. So, he remained in town overnight while they sent him the proper cabling so he could reconfigure the sport PEM to a non-sport PEM. So, there is a difference in the software, not necessarily physically. In the end, it all made no difference in that the engineers determined my original PEM was fine and had done what it was designed to do. They reinstalled the original PEM and decided to make a software adjustment to the heat limit the PEM was supposed to allow.
