Ticket price for the Roadster has not been disclosed by the Italian marque, however the Sian coupe the Roadster is based on was priced at more than AU$5 million during the limited production run of 63 cars.
Far more exclusive, the Roadster will be built in a limited production run of just 19 cars – and Lamborghini says every Sian Roadster has already been sold.
As with the Sian coupe, the Roadster picks up a 6.5-litre naturally-aspirated V12 engine with 577kW. With the addition of a 48 volt hybrid system – that uses lightweight supercapacitors instead of heavier, conventional batteries – power is raised by 25kW, bringing the total output to 602kW and 760Nm.
The result is claimed 0-100km/h sprint time of less than 2.9 seconds on the way to a top speed exceeding 350km/h.
“Smart-material elements” operate vanes in the rear of the Sian Roadster, which react to temperatures generated by the exhaust system, rotating and providing cooling for other components.
Lamborghini says the Sian takes styling cues from its classic Countach model, and in the Roadster this means aerodynamic ‘airstreamers’ placed behind the driver and passenger.
A carbon fibre front wind-splitter (that’s also incorporated into the headlight design) directs air through the bonnet, side air intakes and outlets and over the rear spoiler. Lamborghini claims this wind-bending trickery results in the roadster suffering no loss of 'aerodynamic efficiency' compared to the coupe.
