Lamborghini Unveils The Rare And Powerful Sian Roadster

Lamborghini has unveiled the Sian Roadster, an even crazier version of the carmaker's most powerful hybridized hypercar, the Sian.  The Lamborghini Sian Roadster is a topless version of the most powerful car in the company's portfolio. Talking about the usual crazy Lambo design the Sian Roadster ditches the roof but otherwise maintains the same design cues as its coupe counterpart.Drawing inspiration from the Terzo Millenio concept car, the Sian points toward the future for Lamborghini’s design language. Intense details like the three-prong front lighting signature and triple taillight layout are eye-catching, to say the least.Smaller touches like the side intakes and hydraulic rear wing make everything a bit more special.The Sian Roadster is the most powerful Lamborghini ever. It has 819 horsepower, thanks to a 6.5-liter V12 borrowed from the Aventador SVJ but then adds a 48-volt mild-hybrid system.With over 800 horsepower and all-wheel drive, the Sian Roadster is absolutely blistering in a straight line. Lamborghini claims that the car reaches 60 mph (100 kph) is less than 2.9 seconds, and onward to a top speed of nearly 218 mph (350 kph).The Lamborghini Sian coupe was already extremely rare with just 63 units going into production. The Sian Roadster is even more special with 19 units total, so rare that Lamborghini hasn't even put an exact price tag on the Sian Roadster. But it could be potentially as much as $3,700,000.
