tronically open the rear window, which functions as a windshield when closed and when open, as an amplifier of the unique engine sound of the natu- rally aspirated V10. With the roof down, a distinctive design solution with two movable fins has been developed. The fins become visible during the opening process, ris- ing out of the folding roof casing and perfectly defining the design of the open car. Enhancing the car’s low, powerful appearance, these rear fins that start at the seatbacks continue the roof line to the rear, perfectly shaping the side view of the Spyder. An integrated duct reduces turbulence in the headroom during open top driving.
For even further comfort there are two removable lateral wind guards damping the lateral aerodynamic pulsations, thus ensuring perfect acoustic comfort that allows a conversation even at high speeds. Aerodynamic studies have resulted in leaving the upper part of the windshield free from any wind nets or mobile spoilers. A simple wind brace is discreetly embellished tone-on- tone with the Huracán Spyder’s logo, or can be additionally personalized. Last but not least, the two fins contribute to optimizing airflow through the engine compartment, which is covered by a slatted engine bonnet specific to the Spy- der. The air intakes of the engine compartment are painted in black.
Chassis
The hybrid chassis of the Huracán Spyder LP 610-4 combines aluminum com- ponents front and rear with extensive carbon fiber elements in the occupants’ cell. The exterior skin is made from aluminum. This lightweight chassis pro- vides exceptional torsional stiffness for an open top car, improved by 40% over its Gallardo predecessor, and delivering the handling precision of a race car whilst forming the backbone of the lightweight engineering concept. The new Spyder boasts a dry weight of just 1,542 kilograms (3,399 lbs), giving it a power-to-weight ratio of 2.53 kilograms (5.57 lbs) per hp. The Huracán Spyder’s outstanding aerodynamics include a fully flat and smooth underbody, while a large diffuser dissipates air beneath the rear end and a fixed spoiler is integrated into the tail. In terms of downforce, the Hu- racán Spyder exceeds its Gallardo predecessor by 50%, and with roof closed benefits from a very low drag coefficient with wind noise virtually eliminated.
Drive
The naturally aspirated, long-stroke V10 engine delivers its full, engaging po- tential in the Huracán LP 610-4 Spyder, especially with the top down. Offer- ing the same technical qualities as in the Huracán Coupé, it is a sportscar engine at its very best. It is extremely responsive, revs up to 8,700 rpm and composes a richly tuneful and unmistakeable symphony of sound. From its 5.2-liter displacement, it generates 449 kW / 610 hp at 8,250 rpm, delivering 560 Nm (413 lb-ft) of torque at 6,500 rpm. The “Iniezione Diretta Stratificata” combines direct and indirect gasoline injection. The top speed of 324 km/h (201 mph) and the acceleration figures – 0 to 100 km/h (62 mph) in 3.4 seconds, 0 to 200 km/h (124 mph) in 10.2 seconds – confirm the uncompro- mised performance of the two-seater Spyder. Thanks in part to the new stop start technology and cylinder on demand, i.e. the deactivation of one cylinder bank under partial load, its ECE standardized fuel consumption is a mere 12.3 liters per 100 km. The Huracán Spyder’s CO2 emissions have been reduced by 14% compared to the Gallardo Spyder, despite a significant increase in performance.
The “Lamborghini Doppia Frizione” (LDF) 7-speed dual-clutch gear- box shifts at lightning speed. At the heart of the transmission is a hy- draulic multi-plate coupling. The fully electronically controlled coupling, which is actively cooled for maximum performance, can switch the torque freely between the two axles, with perfect weight distribution of 43/57 front/rear, as in the coupé. At the rear, a mechanical differential lock en- sures powerful traction. As in the coupé, the ANIMA switch (Advanced Network Intelligence MAnagement) on the steering wheel allows various driving modes to be selected, from sporty and dynamic to extreme perform- ance and handling. The three different programs “Strada,” “Sport” and “Corsa” impact the characteristics of the engine, sound, transmission, all- wheel drive and ESC handling system. Working in the background is the LPI system (Lamborghini Piattaforma Inerziale). Six sensors supply infor- mation on the car’s movement; the LPI then sends the information at light- ning speed to all handling systems.
The standard-fit carbon-ceramic brake system provides the Huracán Spyder with immensely powerful and reliable deceleration. The front discs measure 380 millimeters (14.96 in) in diameter and, as an option, Lamborgh-
