The rumours are about to become a reality: a topless Bugatti Veyron debuts in a few weeks.

Due to arrive at the Pebble Beach Concourse d'Elegance on 17 August, the targa-style supercar will be known as the Grand Sport.

Although the open-air car will feature a removable hardtop, a fabric cover can take its place if the weather changes while you're driving around in your $2.25-million beast.

Chopping the bit of aerodynamically-essential roofline has also resulted in the technicians at Bugatti having to reinforce the chassis, but the new roof has been developed so as to prevent a draft inside.

And in keeping with the Veyron legend, the Grand Sport is one of fastest open top cars, even though the top speed is limited to just 347km/h.

You'll have to be even faster if you want to snap one up — just 80 cars will be built.
