Lamborghini Sian FKP 37

The Lamborghini Sián FKP 37 is a limited production mid-engine hybrid sports car produced by the Italian automotive manufacturer Lamborghini. Unveiled online on 3 September 2019, the Sián is the first hybrid production vehicle produced by the company. The name Sián comes from a Bolognese word which means a flash of lightning (shine). The name was selected to highlight the fact that the car is the first production vehicle produced by the company to include a hybrid supercapacitator component. The suffix FKP 37 is related to the initials and birth year of the late Volkswagen Group chairman Ferdinand Karl Piëch. Based on the Lamborghini Aventador, the Sián FKP 37 shares its engine with the SVJ variant of the Aventador, but an electric motor integrated into the gearbox adds another 25 kW (34 PS; 34 hp) to the power output. Other modifications to the engine include the addition of titanium intake valves, a reconfigured ECU and a new exhaust system raising the power output to 577 kW (785 PS; 774 hp) at 8,500 rpm and 720 N·m (531 lb·ft) of torque at 6,750 rpm. The total power output is 602 kW (818 PS; 807 hp), making the Sián the most powerful production Lamborghini. The engine is connected to a 7-speed automated manual transmission and the car employs an electronically controlled all-wheel-drive system with a rear mechanical self-locking differential for improved handling. The power for the electric motor is stored in a supercapacitor unit instead of conventional lithium-ion batteries. The supercapacitor unit is integrated with the electric motor into the gearbox for a better weight distribution. A supercapacitor was chosen as it provides three times the power of a conventional lithium-ion battery of the same weight. The unit installed in the car is an evolution of the Aventador's starter motor and can store ten times more power than the unit it is based on. A regenerative braking system helps generate enough energy to recharge the supercapacitors. The electric motor counters the effect of deceleration and provides a power boost to the driver at speeds up to 130 km/h (81 mph). The motor supports low-speed manoeuvres such as parking and reversing. The improvements made to the car help accelerate it from 0 to 100 km/h (62 mph) in 2.8 seconds and attain an electronically limited top speed of 355 km/h (221 mph) but the official top speed is to be confirmed. Production of the Sián FKP 37 was limited to 63 units for the coupe and 19 for the roadster and all have already been sold. Lamborghini's Ad Personam division will be responsible for the manufacture of the Sián. The car was officially unveiled to the public at the 2019 Frankfurt Motor Show configured in a unique "electric gold" paint. It was also renamed to be known as the Sián FKP 37 honouring late Volkswagen Group chairman Ferdinand Piëch. "FKP" are the initials of his name and "37" are the last two numbers of his birth year (i.e. 1937).
