Cayenne's instrument cluster is tucked under a single, prominent arch, with two big gauges on either side of a central multifunction display, tachometer on the left, speedometer on the right. This display presents information on audio and trip functions, mechanical operations and ambient conditions. Cruise control and the switch for the wipers are located on stalks on either side of the steering column. The bulk of the switches, including audio and climate controls, are racked in the center of the dash above the center console. These are replaced with a CRT monitor on Cayennes equipped with Porsche Communications Management. A dozen vents throughout the cabin distribute warm or cool air evenly. Big, wide outside mirrors offer good rearward visibility. The steering wheel tilts and telescopes to help ensure a proper driving position.

The Cayenne is not as richly appointed as a similarly priced Range Rover, but it's not supposed to be. The emphasis here is sporting flair rather than traditional luxury. (We like both vehicles for different reasons.) We liked the contrasting stitching on the Porsche seats. The standard leather upholstery is high grade, while the standard metal trim has a brushed finish. The front seats stand out for their balance of support, comfort and adjustment range.

The navigation display screen is one of the largest we've encountered. Called Porsche Communications Management, the navigation system comes with a 6.5-inch display and calculates routes and makes adjustments very quickly. It uses DVDs rather than CDs, allowing for maps for the entire United States on a single disk, rather than several that must be changed from region to region. An optional electronic logbook automatically records the mileage, journey length, date and time, starting point and destination address for every trip made. In addition, buyers can opt for a module that will help you find your way back to your starting point, even if the roads or trails aren't on the system's map. Voice recognition and off-road navigation are available options.

Cayenne transports five adults in reasonable comfort. The rear seat is well contoured, with excellent headroom and decent legroom, even when the front seats are well back in their travel range. Seating for five is something we're not used to seeing in a Porsche, so don't expect the interior volume of a Lincoln Navigator and don't look for a third-row seat because it isn't available.

The rear seatback folds forward in a 60/40 split, and includes a pass-though slot with a ski sack, allowing Cayenne to haul longer, narrow items inside without flattening or messing up the rear seat. A cargo net keeps grocery bags and other items from sliding around during travel and a retractable shade-type cover opens and closes over the cargo hold.

Cargo capacity is nearly 62 cubic feet with the rear seats folded down, and nearly 19 cubic feet with the rear seats in place.. The tailgate is two-stage, so either the glass or entire gate can be opened upward, and the electronic latch lets you simply lower the gate to the latch while the electric mechanism pulls it shut. The dimensions of the tailgate opening and load floor allow Cayenne to haul small appliances such as a bar-size refrigerator or a large TV set. With apayload of 1600 pounds, the Cayenne can haul just about anything that'll fit inside without worrying too much about exceeding recommended weights. New for 2008 is a system designed to ease cargo loading and unloading that uses rails and a sliding floor called Storage Space Management.

The 2008 Porsche Cayenne is available with a Panorama Roof comprising four glass panels, three of which slide open under electric power. The massive glass section can be opened either above the first row of seats, the second row, or both rows. A power sunblind is integrated into the roof.
