Tesla isn't done wringing every last drop of performance out of its electric cars, apparently. Elon Musk has revealed that a December software update will improve the off-the-line acceleration of both the Model S and Model X in their ultimate P100D trim levels when using their "Easter egg" (read: Ludicrous) modes. In both cases, it should shave a tenth of a second off both their 0-60MPH and quarter mile times. That doesn't sound like much, but it's a big deal for EVs that are already competitive with the quickest cars on the planet. The 2.4-second 0-60 time for the Model S could make Bugatti Chiron drivers nervous, and a 2.8-second launch for the Model X would put the Bentley Bentayga to shame.

Of course, enthusiasts will tell you that these times don't tell the whole story. Gas-powered supercars may be slower to start, but tend to catch up and sometimes pull ahead when given enough roadway. You wouldn't want to bet your Tesla on a drag race. Still, the upgrade is a testament to one of the less heralded advantages of electric vehicles -- you can get free performance upgrades without having to lift a finger.
