4000040 LEGO Fire Engine is a Exclusive LEGO Inside Tour set from 2023. The set is s a brick-built replica of a 1940s wooden fire truck and designed by LEGO Design Master Henrik Andersen. The original toy is on display in the LEGO Group’s internal museum in Billund, which inspired LEGO House Senior Experience Designer Stuart Harris to suggest recreating it for an Inside Tour set. The 2023 LEGO Inside Tour set was limited to just 60 copies per tour and each are individually numbered.

The set's model feature a turntable ladder that can be rotated at a certain angle. You can also extend the ladder with a crank. There are four printed pieces included, including two bricks with the old LEGO logo from 1940 and two printed 4×6 slopes for the fire engine grille. These parts are all exclusive to the LEGO Fire Engine.

This set had a total of 300 copies, divided into five Inside Tours, each with 60 hand-numbered editions. Every Inside Tour has a unique box sleeve featuring the group photo from the first day, explaining the 'out of 60' label on the box. Of these, 35 copies are given to tour attendees, and the remaining are distributed among LEGO employees responsible for organizing the event. This year marks the first time there are five Inside Tours; previously, there were four tours each year, with 80 numbered sleeves created for each tour.

It was retired in November 2023 with a lifespan of 8 months. The current value for a new and sealed LEGO Fire Engine is estimated to be around $5,745 today, with an average annual growth of about 22.2%. However, it is expected to level off to around 5.8% annual growth next year, making it a solid investment.
