Introducing the Lamborghini Huracan STJ: The Ultimate Hardcore Version of the Huracan STO

V10-powered Huracan family’s final send-off name and logo leaked in trademark filings.

Lamborghini is gearing up to launch the highly-anticipated successor to the Huracan, which will feature a hybrid V8 engine. However, before this new model hits the market, the Italian automaker has one last hurrah planned for the V10-powered supercar. This final version of the Huracan has been officially named the Lamborghini Huracan STJ, as revealed through two trademark filings discovered by CarBuzz on February 27, 2024. The filings, which were submitted to the European Intellectual Property Office, include the name “Huracan STJ” as well as the suffix “STJ” on its own. The official logo for the upcoming model was also unveiled, featuring a bold red J that is connected to the letters S and T.

We have high expectations that this upcoming model will serve as an even more intense iteration of the current Huracan STO, and may even be exclusively designed for racing purposes.

In the past, Lamborghini has utilized the J suffix on limited edition vehicles, with their most notable example being the Aventador J, paying homage to the Miura Jota. The term “Jota” comes from the Spanish word for the letter J and was chosen as a nod to the FIA’s Appendix J rules for racing. This specific model was designed by renowned automotive engineer and test driver Bob Wallace in 1970, catering to the needs of hardcore racers. Unfortunately, only one Miura Jota was manufactured and it met its demise a year later in a fiery crash.

The Jota suffix resurfaced in 1995 with the introduction of the Diablo Jota. A limited production run of only 28 units was produced, featuring a kit that removed the Diablo’s street-legal status. The modifications were extensive, resulting in a significant boost in power and torque. Notable changes included alterations to the interior and exterior, such as the addition of a roof-mounted ram air intake scoop and a raucous exhaust system – a major factor in its ultimate lack of road legality.

In 2012, Lamborghini unveiled the Aventador J (pronounced Jota), a unique version of the Aventador with no roof designed for pure speed. This was soon followed by another Aventador-based model, the Aventador SVJ (Super Veloce Jota), which was released in 2018.

The Huracan STO was created as a way to bid farewell to the second-generation V10 supercar, along with two other variants: the Huracan Sterrato and Huracan Tecnica. STO stood for Super Trofeo Omologata, paying homage to the Lamborghini Super Trofeo racing series. The car showcased a unique one-piece clamshell hood, a striking rear wing, a simulated roof scoop, and a robust 5.2-liter naturally aspirated V10 engine producing 631 horsepower.

However, by replacing Omologata with Jota, it is improbable that the STJ will receive homologation for street use. As a result, we may witness a significant increase in the power output and a drastic decrease in the vehicle’s weight.The substitution of Omologata with Jota implies that the STJ will most likely not be approved for road legality. This could potentially result in a substantial boost in horsepower and a considerable reduction in the car’s overall weight.

It is our belief that the Huracan STJ could potentially be a modified version of a legitimate Super Trofeo competition vehicle or potentially an STO model with its performance pushed to the maximum. Regardless, it is likely to deliver a level of excitement and power on par with or possibly even surpassing that of the Abt XGT – a road-legal beast created from the foundation of an Audi R8 GT2 racing machine.

Unfortunately, the trademark applications merely indicate that the name and emblem will be used for automobiles, mini replicas, and a range of car-related electronic gadgets. Thus, we’ll have to patiently await Lamborghini’s official announcement.
