Volkswagen has revealed that the production version of the California XXL will be called the Grand California. The range-topping camper van is set to make its public debut at the Dusseldorf Caravan Salon in Germany.

The Grand California is based on the medium-wheelbase Crafter van, with a total length of 5986mm (just a touch shorter than the long-wheelbase Rolls-Royce Phantom). It sits above the Transporter T6-based California in the range.

A high roof will ensure that adults can stand up inside the camper van, although the images accompanying the announcement show that it’ll ditch the concept van's extension over the tailgate.

Inside, the Grand California follows the concept in having a large (840 x 800mm) wetroom bathroom, in addition to berths for two adults and two children. A small integrated kitchen incorporates a sink, gas hob and two fridges – one a 70-litre pull-out item – while the front seats swivel around to complement a double bench seat in the living area.

Further features include automatic lighting that comes on when you enter the bathroom, Bluetooth-controlled speakers in the living area, an external shower and an electric step. The options list includes a high bunk bed with panoramic skylight, a roof-mounted air conditioning unit and solar panels on the roof.

Pricing is yet to be announced, but given the medium-wheelbase Crafter’s starting price of £30,611 (compared with the Transporter T6's £25,055 and the California’s £46,625), a starting price £60,000 or more could be attached to the Grand California. What's certain, though, is that a 2.0-litre diesel engine will power the camper van, as it does in the Crafter. The Grand California will also be offered with the option of 4Motion four-wheel drive.

Two-tone paint will be available, as on the California, as will the same gadgets, such as a fold-out awning and dining set.
