Tesla Model S P100D will become insanely fast after software update

Tesla's Model S P100D is already one of the fastest production cars in the world. Announced in August 2016, it goes from 0 to 60 mph in 2.5 seconds (according to Tesla). That's in range with supercars such as the Porsche 918 Spyder, which claims the same acceleration figure.

Now, according to Tesla CEO Elon Musk, the fastest Model S will become even faster after a software update due next month.

Following the update, the Model S P100D will go from 0 to 60 mph in 2.4 seconds. And it will run a quarter mile in 10.6 seconds -- pretty wild numbers that put it neck and neck with supercars that cost several times as much.

For comparison, Rimac Concept_One, the Croatian electric supercar that beat some of the fastest cars in the world (including the Tesla Model S P90D) in a head-to-head quarter-mile race, is rated at 2.6 seconds for 0 to 60 mph and does a quarter mile in 9.9 seconds. It is, however, priced at $980,000, while the Tesla Model S P100D starts at $134,500.

Tesla added that the update will also apply to Model X, which will also shave 0.1 seconds off its 0 to 60 mph and quarter-mile numbers.

Musk calls this update an "easter egg," meaning it should somehow be hidden, (although it's not entirely clear how). He also didn't say what the update will mean (or whether it will even apply) to other Tesla cars. But it's impressive to see that an over-the-air update can make such an incredibly fast car even faster.
