Wrightbus is currently building a new bespoke open-topper for a yet-to-be-named UK customer.
To be used on tourist sightseeing, it is on Volvo’s B5 chassis and the structure has been redesigned to account for the open-top section. The front section also has two opening sunroofs.
To provide a glazed section in place of the thick A-pillar on the top deck, the frontal structure has been redesigned.
