Power tailgate was also a standard feature aiding in the loading and unloading of the FX37s 24.8 cubic-foot regular storage space. When the rear seat is folded, the interior of the luxury crossover vehicle can hold up to 62 cubic feet of cargo. Configured to seat up to five passengers, the 2013 Infiniti FX37s interior included leather upholstery, eight-way power-adjustable front seats, RearView Monitor, dual-zone automatic temperature control, Bluetooth connectivity and an 11-speaker Bose Premium Audio sound system as standard equipment.
