When the Porsche Cayenne was launched four years ago enthusiasts cried blasphemy. Porsche should not build sport-utilities, they said, Porsche should build sports cars. But buyers won the vote. Cayenne had what they needed in a five-passenger SUV: more cargo space than a sedan, off-highway capability, and impressive towing capacity.. They found the Cayenne technologically advanced and remarkably fast, as Porsches are supposed to be. So, they wondered, why all the hand wringing?

Cayenne's balance of style, performance, and sport-utility virtues were compelling, and it quickly became a success story for the small manufacturer of legendary sports cars. When Porsche launched Cayenne as a 2003 model, executives said they hoped to sell 20,000 of the SUVs a year. Clearly, these projections were conservative. Last year, Porsche sold more than 50,000 Cayennes. More than 150,000 have been sold in the past four years. Now, redesigned for 2008, sales of the new version have taken off, and overall Porsche sales in the U.S. hit record levels the summer of 2007. The Cayenne has been a boon for Porsche's financial planning. Its ongoing success smoothes over wildly fluctuating sports car sales, which tend to follow the consumer confidence index. Cayenne's success is helping Porsche do what enthusiasts want: develop and build great sports cars. Enough hand-wringing already.

For 2008, the Porsche Cayenne has been significantly improved, and Porsche is calling it a second-generation version. We can report the driving dynamics of the 2008 Cayenne models are substantially improved over the high bar set by the previous models. This was accomplished by using the latest technology and high-quality engineering and manufacturing. Porsche Stability Management has been enhanced, Dynamic Chassis Control is available, and there's a new Sport mode available for all models and powertrains.

Each of Cayenne's three available engines is bigger and substantially more powerful for 2008. Benefiting from direct fuel injection, each engine is more fuel-efficient, as well, though on the window stickers it's a wash due to more stringent EPA test procedures instituted for all 2008 vehicles.

Grabbing headlines is the 2008 Porsche Cayenne Turbo, boasting 500 horsepower and 516 pound-feet of torque from its new twin-turbocharged 4.8-liter V8 and capable of propelling this SUV from 0-60 mph in just 5.1 seconds. It's faster and more dynamic than the previous Cayenne Turbo.

But the bigger gain, in our view, is with the entry model, which comes with a new 3.6-liter V6 that produces 290 horsepower and 283 pound-feet of torque, capable of propelling it from 0 to 60 mph in less than 8 seconds (and in 7.5 seconds when equipped with the standard six-speed manual transmission).

The popular Cayenne S gets more power, as well, serving up 385 horsepower and 369 pound-feet of torque from its new 4.8-liter V8. More important than the new engines (though less useful for bragging rights) are advances in active safety: An available system called Porsche Dynamic Chassis Control nearly eliminates body roll, or lean, in turns, improving handling, comfort, and active safety, while providing enhanced off-pavement traction. A Cayenne going flat-out through a fast corner with this system looks like it's on rails. A Cayenne without this system struggles to keep up, heeled over and moving around in the turn. Porsche Dynamic Chassis Control includes active anti-roll bars, which are designed to compensate off pavement, as well. All Cayennes come with Porsche Stability Management, Trailer Stability Control, off-road ABS, and other technologies that make drivers look like heroes.

Braking has been improved for 2008. Massive new brakes were developed by Porsche to reduce fade, the tendency of brakes to lose effectiveness in repeated hard use. This is important when descending long mountain grades. We found the 2008 Porsche Cayenne enjoyable to drive, smooth, stable, responsive. It inspires confidence and we felt comfortable driving it right to and beyond grip levels on a gravel road. It's easy to control and predictable and always behaves as expected.

Cayenne comes with a 3.6-liter V6 (that produces 290 horsepower, 273 pound-feet of torque). Leather seating with 12-way power adjustment comes standard, along with titanium interior trim; manually controlled climate control with charcoal and micro-particle cabin filtration; heated retractable exterior mirrors; multi-function trip computer; 12-speaker stereo with CD; air conditioned glove compartment; cruise control; insulated laminated privacy glass; Homelink; immobilizer anti-theft alarm; and an electronically latching power tailgate. Optional for 2008 is natural Chestnut Brown leather upholstery in a two-tone combination with black nappa leather.
Cayenne S gets a 4.8-liter V8 (that delivers 385 horsepower and 369 pound-feet of torque). Cayenne S adds automatic climate control with dual front-passenger settings and a 350-watt, 14-speaker Bose stereo.

Cayenne Turbo features a twin-turbocharged version of the V8 (rated at 500 horsepower and 516 pound-feet of torque). The Turbo comes standard with an adjustable air suspension with Porsche Active Suspension Management (PASM). The Turbo model also upgrades with heated front and rear seats, a power steering wheel adjustment, and park-assist radar warning front and rear. It's equipped with Porsche Communications Management (PCM), a GPS navigation system with integrated telephone and audio controls, and headlights that turn with the steering wheel.

Options include a push-button Sport mode; PASM ($2,990); wood trim packages ($1,385); front and rear park assist ($990); trailer hitch and ball ($630); and 21-inch wheels. Seat upgrades and a full Smooth Leather package that covers everything from grab handles to the center console in hide ($3,040) are available. Porsche Entry and Drive ($995) allows a driver to unlock and start the Cayenne by pulling the door handle and touching the shift lever, while leaving the keys in his pocket or her purse. XM Satellite Radio is available. Features on upper models are available as options on Cayenne and Cayenne S. Porsche's factory customization program allows buyers to order a Cayenne however they want it, limited only by imagination.

Safety features on all models include Porsche Stability Management electronic stability control, traction control, antilock brakes with off-road capability, and Trailer Stability Control. Six airbags come standard: dual-stage front and side-impact airbags for front passengers, and curtain-style head protection airbags on both sides of the cabin. All five seating positions have three-point belts with pretensioners to instantly tighten them and limit stretching on impact. The front belts also have automatic force limiters, reducing potential for belt-related injuries. New for 2008 is a rollover sensor designed to trigger seat belt tensioners and curtain airbags.

For 2008, Porsche Cayenne was redesigned to present a more aggressive appearance. Its designers wanted to lower the car's visual center of gravity. So for 2008, the headlights were moved farther apart and feature new bi-xenon designs. The air intake was re-shaped, the roof section is three inches longer and a rear spoiler adorns the trailing edge of the roof. The 2008 models benefit from new wheel designs;17-, 18-, 19-, 20-, and 21-inch wheels are available. Aerodynamics are improved for 2008: The 2008 Cayenne slips through the air with a 0.35 coefficient of drag, compared with 0.39 for the first-generation (2003-07) models. New taillights, a redesigned rear bumper cover, a new exhaust system, and a new diffuser setup highlight changes to rear for 2008. The outside mirrors mimic the shape of the tail lights.

Cayenne is easily identifiable as a Porsche with headlights and grillework that resemble that of the 911 and Boxster. The more powerful models have functional design cues indicating higher levels of performance. The Cayenne Turbo is distinguished by larger grilles that increase the amount of air flowing through the engine bay.

The Cayenne is not small, measuring nearly 189 inches in length, with a wheelbase of 112.4 inches. That's about the same length as the current BMW X5 (191.1 inches) and Mercedes M-Class (188.5 inches). Cayenne is 75.9 inches wide, about the same as the X5 (76.1 inches) or a half-inch wider than M-Class (75.2 inches).

In size, Cayenne most closely matches Volkswagen's Touareg, which is no surprise given the two vehicles were developed jointly by Porsche and VW. Engines and other Cayenne components are built by Porsche in Zuffenhausen, Germany, and mated to the Cayenne at an assembly plant in Leipzig. Cayenne, Touareg, and the Audi Q7 share basic structures, though the Audi is stretched for more passenger space. Engine and suspension tuning, styling and all the finish work were the separate responsibility of each manufacturer.

The Cayenne offers near optimal front/rear weight distribution of 52/48 percent, for outstanding handling balance in all circumstances (the weight in most unladen SUVs is more heavily biased toward the front). At least as important, in Porsche's view, is the Cayenne's optimal aerodynamic balance. Aerodynamic downforce on the rear wheels increases with speed, delivering the high-speed stability that has become a Porsche trademark.

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.
