The over-all appearance of the car has changed, with the most obvious being the open top (hence the Roadster name). The design of the rear is also different, with new eyelid-like fixed flaps that continue with the design and eventually end on the rear lights. The rear engine cover also has a new shape to adapt to the roadster form and now has vents for efficient cooling. The wheels are unique and specifically constructed for the car. Another significant change is the car having conventional doors instead of the Gull-wing doors. The Huayra roadster, similar to the BC uses carbon triax, a new material that helps further save weight while maintaining strength.
The vehicle utilises the same twin-turbo V12 engine as the coupé, but now has a total of 754 hp at 6200 rpm and 1,000 N⋅m of torque at a meagre 2400 rpm. All of this power is delivered to the rear wheels via an all-new 7-speed automatic manual transmission by Xtrac.
Only 100 units will be available of the BC roadster and is said to have been sold out significantly before production completion.
