Even the "slowest" Model S will hit 60 in about 5.6 seconds, same as a 2013 Porsche Boxster. The most performance-oriented model, intuitively named the Model S Performance, will hit 60 in around 4.4 seconds. Motor Trend tested the Performance model and got an even more impressive, 3.9 second run to 60. That's fast enough to seriously worry a new BMW M5 or Mercedes CLS 63 AMG.
