1.5 seconds faster than what? I compared 0-60 times between the S and the 3. The Model 3's published 0-60 is 5.1 or 5.6 seconds depending on whether you look at the base model or the long-range model.

I'm quite confident that the Model 3 drives like my Model S. Acceleration is clearly similar, zero-lag is pretty much an inherent property of the EV drivetrain, and there's no reason to suspect otherwise.
