Companies like Lamborghini aren’t really known for their production numbers. But as far as supercars are concerned, the Huracán has arguably been immensely successful in terms of sales figures with over 20,000 units made. However, all good things must come to an end, and the Italian firm is bidding farewell to its popular V10-powered raging bull.

The final Huracán will be called the STJ, which stands for Super Trofeo Jota. Super Trofeo is Lamborghini’s one-make racing series, while Jota refers to Appendix J of the FIA rulebook that contains regulations for race cars. The latter appears to be a big deal for the automaker as the only other vehicles with such a name are the Miura SVJ and the Aventador SVJ.

What makes the STJ different from the standard Huracán and its various special editions is an aero package developed by Lamborghini’s works team. For the model’s final iteration, the changes are admittedly very subtle. The front end gets a pair of carbon-fiber canards, and the angle of the rear wing has been altered all in the name of additional downforce.

Mechanical grip is provided by four-way adjustable dampers. These are paired with slightly softer springs, which are supposed to give the car more predictable handling manners. The 20-inch center-lock wheels are wrapped in special Bridgestone Potenza tires—a necessity as the 631hp V10 engine delivers power to just the rear axle.

Interestingly, the STJ will have just two choices for the livery. However, it’s safe to say that Lamborghini will accept requests for custom paint jobs if its most valued customers ask nicely and are willing to pay a premium. Speaking of pricing, what we can tell you is that this car won’t be cheap. Interested buyers must also act fast as only 10 units will be made.
