Lamborghini has launched the Huracán STJ, the last Huracán with a naturally aspirated V10 engine, limited to just 10 units worldwide.
The V10 naturally aspirated engine is an iconic part of Lamborghini's history, contributing to the success of the Uracán range of V10 supercars, first introduced in 2014. The farewell Uracán STJ will be followed by an all-new car with a new hybrid powertrain later this year.
Based on the Huracán STO, the Huracán STJ carries on the racing spirit of the Huracán STO while introducing a package of performance upgrades to make it the most powerful car in the Huracán line-up.
The 'STJ' in Uracan STJ stands for Super Trofeo Jota. Super Trofeo refers to Lamborghini's one-make championship, which was launched in 2009, while Jota refers to the J regulation, an appendix to the Federation Internationale de l'Automobile (FIA) regulations that governs the specifications of racing cars. It is also the initials given to many historic models developed for the track with aggressive performance, from the Miura SVJ to the Aventador SVJ.
The Uracan STJ features an exclusive aerodynamic package developed by Lamborghini's dedicated motorsport department, Squadra Corse, based on more than a decade of experience in Gran Turismo competition. The Uracán STO's sophisticated aerodynamics are further enhanced by the addition of the 'Cofango', which integrates the hood, fenders and front bumper into a single piece, while the rear wing is angled by 3° compared to the production model to keep the car perfectly balanced and increase downforce by 101 TP3T.
Like the Uracan STO, the Uracan STJ is controlled by a rear-wheel drive-only seven-speed dual clutch (LDF-Lamborghini Doppia Frizione) and produces a peak power output of 640 hp and peak torque of 57.6 kg-m at 8000 rpm.
Four adjustable racing shock absorbers replace the standard active suspension to significantly improve mechanical grip. The shock absorbers can be adjusted in four directions to optimise rebound and compression in all amplitude zones, allowing the settings to be freely selected according to track characteristics. This allows the car's dynamic control to be optimised and steering precision to be increased while using low spring stiffness.
We developed the Bridgestone Potenza Race tyre, an ultra-high performance tyre for maximum driving dynamics, and mounted it on 20-inch single-nut wheels. Thanks to these technical features, lap times on the handling track at the Nardò Technical Centre in Italy were reduced by more than a second compared to the Uracan STO.
The sportiness of the Uracan STJ is also reflected in the two different configuration and livery options designed by Lamborghini's design centre, Centro Stile. The first is a Grigio Telesto (grey) body with a Nero Noctis (black) roof and Rosso Mars (red) and Bianco Isi (white) detailing, while the interior features Nero Cosmus (black) Alcantara seats with leather detailing and contrasting Rosso Alala (red) stitching.
The second configuration features a Blu Eliadi (blue) body with a Nero Noctis (black) roof and Rosso Mars (red) and Bianco Isi (white) detailing. Both versions include a carbon fibre plate with the number '1 of 10'. There is also the option to add a customised plate on the passenger side at the customer's request.
