The open-topped two-seater will go on sale next spring, priced at £205,000. It is claimed to be 40% stiffer than its predecessor, the Gallardo Spyder, and will offer 50% more downforce.
Power comes from the same naturally aspirated 5.2-litre V10 engine as the fixed-head Huracán and the Spyder gets an identical 602bhp and 413lb ft of torque.
Despite an increase in the car’s dry weight to 1542kg with a weight distribution of 47% at the front and 53% at the rear. Lamborghini says the Huracán Spyder can reach 62mph from a standing start in 3.4sec (compared with the coupé’s 3.2sec) and go on to a top speed of more than 202mph.
New features for the Spyder include the addition of cylinder-on-demand technology and an engine stop-start system, which will also be included on 2016-model-year versions of the Huracán coupé. CO2 emissions have improved by 14% compared with the Gallardo Spyder's.
The car’s four-wheel drive system has also been reworked, as has its clutch.
The Huracán Spyder features a folding soft-top made from lightweight fabric. It can be folded away in less than 17 seconds at up to 30mph.
Styling changes from the coupé include new buttresses behind the seats and air intakes above the rear wheels. Lamborghini says the Spyder was designed to have different lines from those of the coupé, even with its roof in place.
