The Sián Roadster (2020) is the open-top version of Lamborghini's first hybrid, and the first open-top hybrid Lamborghini. Revealed in July 2020, it carries the same 6.5-liter V12 and 48-volt supercapacitor mild-hybrid system as the Coupe on the same Aventador-era carbon-fiber platform, with the same all-wheel drive and seven-speed ISR gearbox. It has no fixed roof. Lamborghini only built 19, all pre-sold.
