According to the video on the below web link, it is 2.05 seconds....

Just yesterday, Tesla announced the Model S P100D, which it claims can hit 60 mph in a scant 2.5 seconds. If true, that would make it quicker than every other car on the road other than the Ferrari LaFerrari and Porsche 918. For a family sedan, that's insane.
You have to wonder, though. Are we reaching the limit of how quick a car can be on street tires? Obviously, there are Top Fuel drag racers that can hit 60 mph in less than half the time Tesla claims it would take the Model S P100D. But those cars use tires that are radically different from what's used on street cars.
To figure that out, our favorite car nerd at Engineering Explained decided to do the math. Give his latest video a look to see what figure he came up with. It's a fascinating exercise, but the answer's also likely to change as street tire technology advances.
And who knows, when Bugatti finally releases performance figures for the 1500-horsepower Chiron, it could be even quicker.
