Forget cloth, the upcoming Lamborghini Aventador Roadster will use a removable two-piece carbon fiber hardtop, according to the Italian magazine Quattroruote.

The weight-cutting measure means the convertible won't have to stack on the pounds just to include al fresco driving. The carbon fiber roof will weigh less than a cloth top and its underlying metal frame. It also means that the entire rear section of the car won't change from the hardtop model, Quattroroute reports.

We first saw the hardtop in spy photos published in February, though we weren't sure of Lamborghini's plans for the 700-horsepower V12 racer at the time. Lamborghini is expected to debut the roadster at the Paris Motor Show this fall.
