The Lamborghini Sián FKP 37 is a mid-engine hybrid supercar produced by the Italian automotive manufacturer Lamborghini. Unveiled online on 3 September 2019, the Sián is the first hybrid production vehicle produced by the brand.
The name Sián means a flash of lightning in the Bolognese dialect. The name was selected to highlight the fact that the car is the first electrified vehicle produced by the company. FKP is the initials of the late Volkswagen Group chairman Ferdinand Karl Piëch, who died two weeks before the car was unveiled, and the 37 is his birth year of 1937. The car is limited to 63 units, paying homage to Lamborghini's year of foundation: 1963.
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). The total power output amounts to 602 kW (818 PS; 807 hp) making the Sián the most powerful production Lamborghini automobile. The engine is mated to a seven-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 in order for better weight distribution. Supercapacitors were chosen due to their ability to store three times the power of a conventional lithium-ion battery of the same capacity. 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 maneuvers such as parking and reversing.
The improvements made to the car allow it to achieve a 0-100 km/h (62 mph) acceleration time of 2.8 seconds and allow it to attain an electronically limited top speed of 350 km/h (217 mph) but the official top speed is yet to be confirmed.
The Lamborghini Sián FKP 37 was added in the Lamborghini Season Update as a high-end Class S car with the following rank statistics:
- Stock rank: 3,518 ( 85)
- rank: 3,676
- rank: 3,856 ( 25)
- rank: 4,045 ( 29)
- rank: 4,241 ( 38)
- rank: 4,470 ( 54)
- rank: 4,685 ( 69)
The Lamborghini Sián FKP 37 has well-rounded acceleration, handling and nitro efficiency, but low top speed for Class S. It can get around corners without a problem, and its stellar nitro efficiency allows it to recover quickly after drifting even if it does not have much nitro.
Much like the Vanda Electrics Dendrobium, Nissan Leaf Nismo and Porsche Taycan Turbo S, perfect nitro gives a much larger speed boost than the other types of nitro. Therefore, it is important to use perfect nitro rather than single nitro to keep speed.
At stock, the Sián may struggle to keep a high speed as its nitro efficiency is not good enough to maintain perfect nitro, especially since the brake-nitro trick will not work with perfect nitro.
The Sian's blueprints only can be obtained via its Special Event, Lamborghini Season Pass, exclusive card packs, and Ultimate Lamborghini Experience event. These blueprints also appear in the Lamborghini Veneno's Special Event, having a total of 6 blueprints.
The Lamborghini Sián FKP 37 was added in the Fifteenth Anniversary Update as a high-end S Class car with the following statistics:
At stock, the Sián FKP 37 has average acceleration, low top speed, decent drifting and nitro efficiency, and stiff but bearable handling.
At PRO, the Sián displays performance comparable to that of the Lamborghini Centenario LP 770-4: excellent acceleration, high top speed, good handling and drifting, and good nitro efficiency.
Similar to the other cars with the same tier and placement, the Sián is a competitive option for multiplayer and TLEs. The Sián's only drawback are its restrictive availability and use of car-specific kit cards.
As of the 2020 Halloween Update, the Lamborghini Sián FKP 37 can be purchased for 4,000,000 which was previously obtainable by reaching Tier 8 of its Festival. If viewed in the Tag Racing car selection menu, it will show a price of 20,000, however, the option to buy the car is unavailable.
The Sián FKP 37 was on sale during the following dates:
The Sián FKP 37 was made obtainable a second time by reaching Tier 20 with the Premium upgrade in the Lamborghini SC20 Festival. Players who already own the car would win 7x Lamborghini SC20 Kit instead.
