Lamborghini’s V10 engine first made its debut 21 years ago in the Gallardo, the first new engine developed after it was acquired by Audi. Besides the Gallardo, it has been used in the Huracan and also Audi models like the R8.
With the special 10-unit STJ edition of the Huracan announced recently, it also marks the end of the V10 era. The carmaker says that by the end of the year, the Huracan’s successor will be with a new hybrid powertrain.
With a design based on the Huracan STO, the STJ is said to ‘represent the pinnacle of performance achieved in the Huracan family’s history’ with an exclusive package designed to further enhance the racing spirit of the Huracan STO.
STJ stands for Super Trofeo Jota, a tribute to the Lamborghini one-make championship, established in 2009, while Jota refers to Appendix J of the FIA Regulations that sets the racing car specifications. It also references the long tradition of Lamborghini models developed for the track, starting from the Miura SVJ and continuing with the Aventador SVJ.
The STJ stands out with its custom-designed aerodynamic package developed by Lamborghini Squadra Corse technicians, leveraging the know-how acquired over 10 years at the top of Gran Turismo competitions.
The sophisticated aerodynamics of the STO have been further improved with the addition of the iconic ‘cofango’: two all-new carbonfibre aerodynamic appendages (flicks), while the angle of the rear wing has been increased by 3° compared with the production model to ensure a 10% increase in aerodynamic load while keeping the car perfectly balanced.
Like the STO, the STJ delivers a maximum power output of 640 ps/565 Nm which goes through a by a 7-speed dual clutch (LDF – Lamborghini Doppia Frizione) gearbox to the rear wheels.
Traction has been increased significantly by a set of 4 adjustable racing-derived shock absorbers, which replace the standard active components. The shock absorbers are 4-way adjustable to optimize the rebound and compression at both high and low frequencies, giving total freedom of choice in the set-up based on the track characteristics. The special characteristics of the shock absorbers allow lower spring stiffness to be used while maintaining optimal dynamic control of the car and increasing steering precision.
To maximize the driving dynamics, special Bridgestone Potenza Race tyres are supplied. These have been developed with a specific high-grip compound and installed on 20-inch single-nut rims.
The sporty character and exclusivity of the sportscar are also reflected in the aesthetics, with two different configuration and livery options definitively designed by Lamborghini Centro Stile. Both versions also feature a special, numbered carbonfibre plate marked ‘1 of 10’, signifying their exclusivity. In addition, there is the option to add a custom plate on the passenger side according to the customer’s instructions.
