Lamborghini Gallardo LP 570-4 Superleggera, making its entrance to continue the success of its predecessor which was launched in 2007, is mentioned as the new top model in the Gallardo line-up. Having been trimmed by 70 kilograms (154 lb) compared with the Gallardo LP 560-4, the Gallardo Superleggera introduces the lightest road-going model in Lamborghini’s range with a dry weight of no more than 1340 kilograms (2954 lb).
The key factor for the light road-going of the Superleggera is the use of carbon-fiber components for the exterior and interior as well. It is thus supported with the use of the lightweight Gallardo Superleggera 19-inch units wheels made of forged aluminum that save 13 kilograms (28.6 lb). The wheel bolts are made from light and rigid titanium, while the tires are 235/35 ZR19 at the front and 295/30 ZR19 at the rear and come from the Pirelli P Zero Corsa series. With all exterior modifications directed at increasing aerodynamic effects, the Lamborghini Gallardo LP 570-4 Superleggera is said to bring a whole new meaning to the term “super sportscar”.
In the Gallardo LP 570-4 Superleggera, LP stands for “longitudinale posteriore” and refers to the orientation of the V10 engine – which is mounted longitudinally behind the driver, just like every Lamborghini engine. The number 570 refers to the maximum power output in CV, which equates to 419 kW and is available at 8,000 rpm. Equally impressive is the pulling power – the torque curve peaks at 540 Nm (398,3 ft lbs) at 6,500 rpm. The increase of 7 kW (10 CV) is the result of the new dedicated engine management strategy.
The V10 has a displacement of 5204 cm3 and achieves a specific output of 80.5 kW (109.6 CV) per liter. Special features on this long-stroke engine with an aluminum crankcase include dry sump lubrication and a cylinder angle of 90 degrees. Both solutions lower the center of gravity, thus improving the handling dynamics. To ensure an ideal combustion chamber fill, the engine has an adjustable intake manifold and continuous control of the chain-driven camshafts.
The Gallardo Superleggera is also considerably more efficient – compared with its predecessor, its fuel consumption in the EU driving cycle is reduced by 3,5 liters per 100 kilometer (0,9 gal), or 20,5 percent, to 13,5 liters/100 km (16 mpg). This improvement is partly due to the “Iniezione Diretta Stratificata” gasoline direct injection, which injects fuel into the combustion chambers at pressures of up to 100 bar. The tumbling mix cools the combustion chambers, which enables a very high compression ratio of 12.5:1 which, in turn, increases efficiency.
