Lambo's top roadster gets even more power.

Lamborghini has unveiled the Aventador S Roadster ahead of the Frankfurt Auto Show.

Following in the footsteps of the previously announced Aventador S coupe, the Aventador S Roadster marks the model line's first significant update since being introduced in 2011. Like it's fixed-roof counterpart, the Aventado S Roadster arrives with slightly revised front and rear fascias.

Lamborghini has also significantly improved the car's aerodynamics thanks to a new active rear wing. Compared to the outgoing model, the Roadster's new adjustable wing improves downforce by more than 130 percent while improving efficiency by up to 400 percent.

Mechanically, the Aventador S Roadster has been upgraded with a new four-wheel steering system for improved agility and stability, recalibrated suspension, and a more powerful version of Lamborghini's 6.5L V12, now making 740 horsepower and 508 lb-ft of torque. Power is routed to all-four wheels via a permanent four-wheel drive system and Lamborghini's seven-speed lightweight Independent Shifting Rod transmission.

The Aventador S Roadster is just 110 pounds heavier than the coupe, meaning it can still accelerate from 0-60 in a lightning fast 3.0 seconds. Top speed is identical to the coupe at 217mph. That speed is scrubbed off in a hurry thanks to standard carbon ceramic disc brakes.

Inside passengers will enjoy a bevy of new color and material options, along with the inclusion of Apple CarPlay.

"The new Aventador S Roadster sets new benchmarks in technology and performance on both road and track, with the roadster version adding a new dimension in driving enjoyment," said Chairman and Chief Executive Officer, Stefano Domenicali. "The Aventador S Roadster offers the thrill of open air driving without compromising on driving dynamics or the occupants' comfort, and adds a further luxurious dimension through the personalization options available."

U.S. pricing for the Lamborghini Aventador S Roadster will start from $460,247. Deliveries are slated to begin in February 2018.
