Drive is delivered to the rear wheels via a seven-speed automated manual transmission and an electronically controlled mechanical differential.
The Roadster rides on 20-inch wheels up front, 21-inch rims at the rear, and specially created Pirelli P-Zero Corsa tyres that can sustain up to 1.8g of lateral force. Stopping power comes courtesy of Brembo carbon-ceramic disc brakes at all four corners, with six piston callipers at the front, and four piston units at the rear.
There's also an active aerodynamics system, and a new Bosch develop stability control system with five settings: wet, comfort, sport, race, and off.
Using a range of carbon and carbon composites, the Roadster weighs 1280 kilograms. That's less than the original Huayra coupe's 1350kg, but more than the 1218kg Huayra BC coupe, which was unveiled last year.
Two types of roof can be fitted to the Huayra Roadster: a removable fabric and carbon cover that can be stored inside the car, and a carbon hardtop with a glass centre that's "very simple and quick to install".
Priced at 2.28 million euros ($3.2 million), only 100 Huayra Roadsters will be built, and all have already been sold.
