Motortrend tests at the Autoclub Speedway dragstrip so I suspect that time was done on a prepped surface. (https://www.google.com/amp/s/www.motortrend.com/news/motor-trend-testing/amp/)Yes, Motortrend did 2.53 seconds without rollout.
It seems like people want to compare the very best times of the Model S with a single test by a TV show with unknown test procedures.
