In March 2010, Lamborghini announced the release of the Gallardo LP 570-4 Superleggera, a lightweight and more powerful version of the Gallardo LP 560-4 in the same vein as the previous Superleggera. With carbon fibre used extensively inside and out to reduce weight to just 1,340 kg making it the lightest road-going Lamborghini in the range. The odd firing 5.2 L V10 on the LP 570-4 gets a power bump over the standard Gallardo to 570 PS (419 kW; 562 hp) at 8,000 rpm and 540 N⋅m (398 lb⋅ft) at 6,500 rpm of torque. Performance has been improved to 0-100 km/h (62 mph) in 3.2 seconds, and a 329 km/h (204 mph) top speed. Taiwan models went on sale in June 2010, with delivery beginning in July 2010.
