On 7 July 2023 at the inauguration of the expanded factory in Ängelholm, Sweden, company founder Christian von Koenigsegg announced details for the production Gemera.

In July 2024 Christian von Koenigsegg said that the three-cylinder powertrain using the Tiny Friendly Giant had been cancelled and the technology shelved for now.

The car features electronically adjustable ride height and a titanium exhaust system manufactured by Akrapovič.

The main design feature of the Gemera is the lack of a B-pillar and two large dihedral doors which open forward to allow easier access to the leather upholstered four-seater cabin.
