Officially, per Tesla Motors, the 85 kWh version (non Performance) of the Tesla Model S does the 0 to 60 MPH sprint in 5.4 seconds.

DragTimes discovered this 5.4-second time to be easily beat when it tested the Model S 85 kWh.

How's 0 to 60 MPH in 4.9 seconds sound?  That was DragTimes was able to achieve in the Model S 85 kWh

As DragTimes states:

"We had some time with a 2014 Tesla Model S 85, the non-performance version and did a quick 0-60 MPH test run with the Vbox. Tesla rates the Model S 85 at 362HP and a 0-60 MPH time of 5.4 seconds. With the battery at less than 50% the Model S ran 0-60 in 4.9 seconds and 0-100 in 12.4 seconds."

"While this is well ahead of Tesla’s quoted numbers, we think it will do even better with a full charge."
