Revealed in the form of digital renderings ahead of its official debut at the 2019 Frankfurt Motor Show which kicks off next week, the Sian boasts the same 6.5-litre V12 naturally aspirated engine that’s used in the Lamborghini Aventador SJV, accompanied by a 48-volt mild-hybrid system.
While the V12 mill churns out 774 hp – 15 more than the Aventador SVJ – the mild-hybrid system adds another 34 horsepower to its powertrain, taking the total output to 807 hp.
The 48-volt mild hybrid system’s electric motor is sandwiched between the engine and the transmission and receives power from a supercapacitor. The system not only delivers a power boost under hard acceleration but also helps return better gas mileage and can power the hypercar on its own at ultra-low speeds.
Lamborghini claims the Sian takes only 2.8 seconds to reach 62 mph from a standstill and the top speed is kept to 217 mph, electronically.
The silhouette of the Sian looks similar to that of the Aventador, but much of the eternal design is unique. It shares several radical design features seen on the Terzo Millennio concept unveiled a few years ago, including the dramatic headlight design and the nose.
The sharp, jagged-lines continue on the profile as well as the rear of the hypercar, which is dominated by six hexagonal LED taillights and a large diffuser with the exhaust tips integrated into it.
“The fastest Lamborghini must be a visual and symphonic feast, as remarkable to those who see it pass by as those privileged to drive it,” says Mitja Borkert, Head of Design at Lamborghini.
“It takes inspiration from the Countach, but the Sian is a futuristic icon, not retrospective.”
Lamborghini will build only 63 examples of the Sian with a starting price of $3.6 million. However, all 63 units have already been sold.
