It appears Tesla’s Ludicrous Mode can go even quicker.

The American automaker’s CEO, Elon Musk, is teasing a “Ludicrous Easter egg” that will uncork the full performance of Tesla P100D vehicles with Ludicrous Mode. In a series of tweets, Musk gave small clues on what the Easter egg will be, suggesting that it will improve zero-to-60 time but it won’t be a significant change.

Following up on Musk’s tweet, DragTimes told the CEO that it is hosting a Tesla shootout on Sunday, Nov. 13 at Palm Beach International Raceway in Florida. Musk replied saying that an early access release might be ready by then, which means those attending could see even quicker quarter-mile times.

He also added that this isn’t the so-called Plaid, saying that its reserved for the next-generation Roadster. Of course Plaid and Ludicrous all pay homage to the movie Spaceballs. Lastly, there’s also a reference to The Princess Bride, with Musk saying Ludicrous Mode is not actually “left-handed,” which means Tesla could have been sandbagging all along. You can learn more about the reference by watching the scene below.
