What is it?
This is the new Bugatti Veyron 16.4 Grand Sport, an open-top version of the 987bhp supercar of which you are almost certainly already familiar.
Unsurprisingly that roof is the stand-out change from the ‘standard’ car – the transparent polycarbonate unit weighs 19kg and can be lifted on and off after pushing two release buttons, but cannot be stowed in the car. As a result, Bugatti has incorporated an emergency carbonfibre soft top that can be stowed in the boot and used at speeds of up to 99mph if it rains.
Beyond that, the bodywork has been modified to ensure the car remains stable at high speeds, safety standards are maintained and wind intrusion into the cabin is kept to a minimum.
For instance, the car has new A-pillars, door sills and a larger centre tunnel to improve strength, while the doors are made of carbonfibre rather than the aluminium of the coupe.
Beyond that, the Grand Sport retains much of the hard-topped car's eye-watering performance capabilities.
What’s it like?
Turn the key and wake the 987bhp, 16-cylinder, eight-litre engine and you are greeted with a smooth, deep sound. It’s not as loud as you might image, but rather distinguished – and perhaps even a bit shy.
