That's just what electric-car manufacturer Tesla did for its new Model S p85D. That's the two-motor, high-performance version of the Model S.
Software updates aren't entirely new, actually. In the past, Tesla has released over-the-air updates for its cars that improved battery life and fixed bugs. That sure beats taking your car into the shop.
This time the update to the P85D boosted its acceleration by 0.1 seconds. That means it can go from 0 to 60 mph in around 3.1 seconds. If you know anything about cars, you know that's up there with million-dollar hypercars from McLaren, Ferrari, Porsche, Lamborghini and Bugatti.
In fact, it's so fast, it leaves the average person in shock. Click here to watch some hilarious passenger reactions to the Tesla's "Insane Mode."
