The kind of ultimate performance machines still follows the fixed roof recipe, which is why, for example, Ferdinand Piech's Porsche 918 is not a Spyder like most of its kind.
Returning to Bugatti, now that the Chiron has all eyes on its hybrid-defying 1,500 hp, we can already look ahead at the various derivatives of Molsheim's machine.
Based on the Veyron's production cycle, we should have six years to wait until Bugatti comes out with something like the Grand Sport Roadster mentioned in the title above.
The Chiron will be produced in 500 units, which means 50 more than the Veyron, but the chemistry of the line-up might change a little bit, since the market seems to have generated shorter life cycles over the past few years. With 170 of those cars having already been ordered, we might be looking at a rushed pace already.
A Bugatti Chiron Grand Sport Roadster would bring a removable roof, as well as an output premium. With the Chiron's new W16 mill, a 200 hp bump, such as the one received by the corresponding Veyron back in the day, shouldn't be an issue. And thanks to the Chiron's carbon construction, the performance compromises made to remove the roof will be minimal.
For now, the shortcut to such a machine comes from the rendering above, with Rm Car Design deserving the credit for the image.
