|JH Italia, Lamborghini Malaysia, last weekend presented the Huracán LP 620-2 Super Trofeo, in conjunction with the Lamborghini Blancpain Super Trofeo Asia Series and World Finals at the Sepang International Circuit.|
The Huracan ST (Super Trofeo) will be the official racer for next season’s Lamborghini Gentlemen’s race series, Super Trofeo Asia and other regions. Built from a clear racing concept, the Huracan ST stresses sophisticated high performance that conforms to motorsport safety regulations. The front and rear lights are now predominantly LED, as on the road going Huracan.
Lamborghini Huracan ST, developed with Dallara Engineering
For the bodywork, the body’s composite materials and aerodynamics have been developed by Dallara Engineering. The aerodynamics now benefit from a rear wing with ten different settings, front and rear diffusers, and adjustable front air intake ducts. Refinements to the Huracán ST include new bodywork ‘fast fittings’, and a new oil radiator providing even more performance than that found on the previous racer, the Gallardo ST.
Last but not least, the Lamborghini Huracán ST will be exclusively equipped with Pirelli tyres: 305/660-18 at the front, and 315/680-18 at the rear.
In the racing-specific interiors the Alcantara in Nero Ade color is used throughout the car, on the dashboard and central tunnel and also on fundamental driving parts, such as the steering wheel, gear selector and ergonomic seats.
The chassis features an exceptionally light roll cage at just 43 kg that extends to the rear axle, and impressive torsional stiffness that represents a massive 45% improvement compared to the previous variant.
The frame is a hybrid carbon/aluminum construction with modified geometries to house an improved radiator up front and better accommodate the racing gearbox at the rear, which also provides better aerodynamics. The dry weight of the Huracán ST is 1,270 Kg, with a weight distribution of 42/58%. Further technical features on the Huracán ST include new engine supports, a new three-disc clutch and an XTrac sequential gearbox developed specifically for the Huracán ST, with an electric actuator designed by Magneti Marelli.
A V10 direct injection engine is mounted on the race version Huracan, which is standard on the road car. The engine is managed by a Motec control unit that delivers a maximum output of 620 hp and an astonishing weight/power ratio of 2.05 kg/hp. The control unit is the MOTEC M182 that controls data, gear changes and the new TFT display mounted on the dashboard. A significant feature of the Lamborghini ST is the rearwheel drive choice as already adopted in the GT classes.
Electronics represent a significant leap forward in development, and now include new lightweight cables and connections specifically for racing. Special features are the traction control and the Bosch Motorsport ABS, with 12 different accessible settings via the steering. The steering is derived for racing and has been developed jointly with OMP. In addition, the steering is hydraulically powered for extra sensitivity and adopts an electric power pump.
Finally, the Huracán ST is mounted with fully adjustable anti-roll bars and two-way adjustable Ohlins dampers.
