The 2021 Lamborghini Sian Roadster, which will produce a total of 19 units, has a 48-volt semi-hybrid system with a 6.5-litre 12-cylinder engine. The car, which has about 820 hp of power combined with the power supply, reaches from 0 to 100 in 2.9 seconds. The Sian Roadster can reach a maximum speed of 350 km/h. The 33-horsepower electric motor integrated into the Sian Roadster’s gearbox allows the vehicle to operate on electric power only in low-speed manoeuvres such as reversing and parking. The lithium-ion battery technology used in the vehicle is three times more powerful and lighter than the same size units on the market. The entire electrical system, including the engine, weighs just 34 kilograms. The ‘recycling brake system’, which charges the batteries when the vehicle brakes, has also been added. The 2021 Lamborghini Sian Roadster will be produced and delivered entirely according to the colour scheme that users want.
