I've received a number of PM/emails about the performance of the roadster Sport and recent firmware changes. I did some data collecting on a friends sport and here's what I found: Yes. The torque in Standard mode is limited to 265 ft-lbs vs 295 ft-lbs in performance. (see plot below) Yes. When VDS 'Performance' turns red, the PEM temp is >= 45C and the max torque is limited to 273 ft-lbs. When 'Performance' is white, the max torque is 295 ft-lbs. The good news is that the PEM fan is very powerful and it cools the PEM down in about 30 seconds. (@26C ambient. YMMV) When the PEM temperature reaches 45C, the max torque will be limited to 273 ft-lbs In the new firmware, the last blue bar is on for PEM temps 43C to 60C. This screen has changed how the battery temperature is displayed. Attached is the data from my 2008 roadster. (I have also checked it against a recent roadster sport VDS ) Disclaimer: My conclusions & data could be wrong. I don't work for Tesla nor have any friends that do. I'm just passionate about Tesla's products and understanding how they work. The data is the result of my own analysis of my roadster and discussions with (and log data from) other owners.
