It has almost been a year since Tesla CEO Elon Musk teased a new Keep Climate On feature specially designed for party animals and campers — now a Tesla hacker who goes by the name of ‘green’ just released a screenshot showing the new ‘Party Mode’ button added to the climate options.

The Party Mode feature has been delayed due to obvious other priorities at Tesla, earlier this year Elon Musk said they had to hold on releasing Party Mode due to prioritizing the Sentry Mode feature.

Elon Musk described the feature in the following words in a tweet:

We’re adding a “party & camper mode” soon to S/3/X, so your car can maintain air flow, temp, selective lights, music & power devices for 48 hours or more while parked. Big batteries rock…

Bjørn Nyland tested the ‘Keep Climate On’ option in extreme winter temperatures of -15°C/5°F and was able to sleep inside his Tesla Model X for 6 hours straight and his further energy consumption analysis showed the car can maintain the climate inside up to 24 hours.
