Hi guys, new member looking into the Tesla Model S from a purely performance car standpoint. I come from a background modifying BMW's for big power and the Model S has me thinking about taking a "new school" approach to modifying cars. Now, from what I read here if the Performance Model S had 4.375C like the 40kWh model was supposed to have output would be in the 506 horsepower range. That's a boost of almost 100 hp and a good amount of torque to boot likely putting the 1/4 mile time and trap speed on par with something like a Panamera Turbo S or the upcoming all wheel drive version of the E63 AMG. The Tesla is respectably quick as it sits but to truly perform like the top guys more torque/power is necessary. I also understand the motors in the cars are basically the same with the inverter being different in the performance model. So is it just software that is holding the car back? Tesla simply chose between the best balance of range and power? I wouldn't mind a high performance mode with less range and replacing the battery earlier wouldn't bother me earlier for more performance. - - - Updated - - - Hmm can't edit my post meant to say "wouldn't bother me either" whoops.
