    While utilizing performance mode will a P90DL selected to mimic a 70 achieve the same watt per mile efficiency of a 70? I figure it might be close but there would be some losses due to the extra weight of the dual versus single motor configuration. Would there be any other differences?

    Is no one using performance mode?

    I kind of doubt it because, I think, all that is doing is limiting the power. Which, I assume, you could do if you just drive conservatively.

    Thus, changing that mode wouldn't change anything in terms of efficiency.

    I am not so sure. I would imagine that modes utilizing only the rear motor would use less electricity. Driving conservatively with one motor is probably more efficient than driving conservatively with two?

    Not positive on it, but getting the dual motor shows increased efficiency with 75 vs 75D. I believe it also showed that when I ordered my 90D.

    I think there's other factors at play, such as motor size. 90 vs 60/75 are the same motor, but I believe the P models have a larger rear motor.

    Somewhere there is info on why the dual motors are more efficient than the singles.

    Rear motor on P's is older generation, more powerful but less efficient.

    I'm not sure the performance mode is really that accurate in simulating the lower power/battery cars. As an example, we test drove a P90DL and a 75D back to back. While we were in the P90DL we used performance mode to simulate the 70D . In real life the actual 75D was simply not as fast as the "simulated" 70D in the P90DL. It was enough of a difference that I noted it to the Tesla rep immediately. My takeaway was that it's just not that accurate a simulation...not that this really answers your question OP!

    what are you talking about? what is "performance mode"?

    if you put your P90D in Range Mode, it will shut off one of the electric motors to be more efficient. other than that i have no idea what you're getting at.

    Since the "nonperformance" cars seem to have better efficiency ratings, I just thought I would play around with the settings and see if I could capture that efficiency.
