Infiniti has debuted a new concept aimed squarely at families at the Pebble Beach Concours d’Elegance.

The seven-passenger Infiniti JX crossover is a three-row model set to go on sale in the US in spring 2012, becoming another contender in the country’s fastest-growing luxury vehicle segment.

Infiniti describes the model’s new shape as that of a greenhouse, promising ‘class-leading roominess’ and an innovative access method to the rear row.

Infiniti is to team up with a group of leading chefs to add extra elegance to a new concept set to be unveiled as part of the Monterey Auto Week in California.

The Japanese brand is working with Hearst Magazines to showcase the new Infiniti JX Concept, which will be revealed at the 61st Pebble Beach Concours d’Elegance.

As part of the reveal, chocolate, cheese and wine tasting sessions have been scheduled, as well as cooking demonstrations from US celebrity chefs including Tyler Florence, Marc Forgione, and Andrew Carmellini.
