The hybrid powertrain of the new model includes a 6.5-liter naturally aspirated V12 engine with an output of 775 horsepower. This engine is also used on the Aventador SVJ. The unit works in conjunction with an electric motor producing 34 horsepower and a seven-speed automatic gearbox. The total output of the car is 819 horsepower. Traction is transmitted to all wheels.
The system is not powered by a lithium-ion battery — for the first time, a supercapacitor is used for this purpose. The device is located between the passenger capsule and the engine for better weight distribution. The supercapacitor is three times more powerful and three times lighter than a conventional battery. Energy can be replenished during every braking event using a special recuperation system. It can be used to boost power during acceleration at speeds up to 130 km/h. This innovation is Lamborghini engineers' own development.
Acceleration to 100 km/h takes 2.8 seconds for the supercar, with a top speed of 350 km/h. In these parameters, the new model does not differ from the Aventador SVJ. However, acceleration from 30 to 60 km/h and from 70 to 120 km/h takes the Sian 0.2 and 1.2 seconds less, thanks to the new energy-saving system.
"With this car, we set ourselves the task of creating the best hybrid solution for a Lamborghini super sports car. This is our first step in the new electrification strategy," said Lamborghini's Chief Technical Officer Maurizio Reggiani.
The new model will be produced in a limited edition of 63 units. The price of the car is $3.6 million. At the moment, all Sian units have already been sold out.
