The car "incorporates innovative structural solutions, designed to ensure the roadster offers the same extremely high levels of performance and passive safety as the coupe version," the company said in a statement to the press. Those enhancements inevitably increases the Veyron's curb weight, but a top speed of 250 mph is still possible with the hardtop in place (or limited to to 217 mph with the roof absent).
MSRP pricing for the Grand Sport remains unknown, but we suspect it will command a considerable premium over the already stratospheric price of the $1.3 million Veyron.
The roof is a relatively simple targa top configuration, rather than a convertible setup. The owner must simply remove the top panel above the two seats to enjoy the open air. There is no room to store the targa top aboard, but the Grand Sport does come with a cloth top intended to be used in unforeseen downpours.
The Bugatti Veyron Grand Sport is slated to begin production in spring 2009.
