    Curious if the 3 being lighter and smaller than the S = a faster car?

    well, the standard S is listed as 0-60 in 5.2 seconds. The 3 (as we know it to be) to be under 6 seconds. so, no. If it were less than 5.2 seconds, they would have said 0-60 in 5 seconds (or just over 5 seconds).

    The standard S RWD is listed at 5.5 seconds. The RWD model 3 is what Elon was referring to. I think it's gonna be 5.7

    Is RWD faster than AWD?

    AWD is faster, and more efficient. The model 3 being lighter doesn't really matter since the vehicle weight depends on the battery size. The bigger the battery, the heavier the Tesla. The bigger the battery, the more power it can send to the motor. The more power it can send to the motor, the faster it can go. I'm sure someone else can explain that in more scientific terms, but that's the gist.

    In engineering terms, one needs to differentiate between speed and acceleration. Maximum speed is dependent on maximum horsepower.
    Power is the RATE at which energy is consumed.
    In the motor, horsepower is the product of speed (RPM) and torque (Lb-ft).
    Acceleration is dependent on torque. In the motor, torque is dependent on current. To get more current you need a bigger battery, more cells in parallel at the same voltage as the smaller battery. Since there is a voltage limit that the inverter can handle, you can't just increase voltage. There is also a maximum safe current that the inverter can handle.
    Two motors mean two inverters as well, so maximum torque and horsepower is greater in The D version.
    Since the smaller motor is more efficient that the larger one in the rear, using the front motor only, for steady highway speeds, results in greater range.

    I would doubt the base Model 3 would be faster than a base Model S. When Elon said "under 6 seconds" I assumed he meant 5.8-5.9 seconds. Of course, if you've never driven or ridden in a Tesla, you don't realize that an electric 6 seconds feels vastly different than an ICE's 6 seconds.
