As the world awaits the debut of the Huracan’s plug-in hybrid successor later this year, Lamborghini filed a new trademark that could be used in another special edition. The Huracan STJ moniker was trademarked in Europe on February 27, making us wonder if Lamborghini is working on a final iteration of the V10-powered supercar. The filing includes the official emblem of the STJ which most likely stands for Super Trofeo Jota. The nameplate is probably conceived as a reference to FIA’s Appendix J regulations and was first used in the Miura Jota prototype in 1970. Other uses throughout Lamborghini’s history include the Miura SVJ, the Diablo SE30 Jota, the one-off Aventador J, and the Aventador SVJ.

Lamborghini‘s filing on the European Union’s Intellectual Property Office was discovered by our colleagues at CarBuzz, mentioning a possible use in vehicles, toy cars, and plenty of other products. At first glance, the STJ would be a fitting name for a more extreme follow-up to the Performante, STO, and Tecnica versions of the Huracan. However, with the electrified successor of the Huracan being just around the corner, this scenario seems unlikely. Still, we can’t rule out another one-off special from the Lamborghini Ad Personam Opera Unica program, tailored to the request of a wealthy client. As the last of the V10-powered Lambos, we wouldn’t be surprised if the model broke the record of the most expensive example of the Huracan.

Such a treat wouldn’t have to be street-legal and could be based on the Huracan Super Trofeo EVO2 racecar, adopting its wild looks, race-prepped 5.2-liter V10, and hardcore chassis setup. Something similar was envisioned in the digital world a few months ago by automotive photographer, CG artist, and filmmaker Jpog, tricking the internet into believing it was the real deal.

In any case, without any official word from Lamborghini, all the aforementioned scenarios are pure speculation. What we know for sure is that if the STJ becomes a reality, you probably won’t be able to buy one, as the remaining production allocation of the Huracan has been reportedly sold out since May 2023.
