The open-air version of the Lamborghini Aventador didn’t appear in Geneva as we expected, but that doesn’t mean it isn’t still in the works. Lamborghini is neither confirming nor denying the existence of the car, but sources with ties to the Italian automaker are leaking what they call “confirmed” design updates.

According to Italian magazine Quattroroute, the car will come to market with a Targa-style removable roof, detachable in two sections. Lamborghini reportedly went this design route in order to keep the Aventador’s engine cover identical between coupe and roadster versions, reducing both production cost and time-to-market.

The roof panels will be made of carbon fiber, and will be split in two pieces for easier handling. It’s not clear if the Aventador Roadster will provide on-board storage for the roof panels, or if (like the Bugatti Veyron Grand Sport) the choice of open-air motoring must be made before leaving the garage.

Quattroroute also says the Aventador Roadster will come to market with the same drivetrain as the coupe, which means a 700-horsepower V-12 will distribute power to all four wheels via a seven-speed sequential automatic gearbox.

With the auto show season now on hold until the fall, don’t expect to see any official news from Lamborghini on the Aventador Roadster before September’s Paris Auto Show. We’ll keep you posted as soon as we hear anything.
