The Cayenne offers an optional collision warning system, which detects an impending crash through forward mounted sensors and flashes a bright light and sounds a loud, distinctive tone to warn the driver to brake or maneuver immediately to avoid a collision. The system also pre-charges the brakes to begin deceleration more quickly. The LX570 doesn't offer a collision warning system.

The Cayenne’s optional blind spot warning system uses digital cameras monitored by computer to alert the driver to moving objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. The LX570 doesn’t offer a system to reveal objects in the driver’s blind spots.

For better protection of the passenger compartment, the Cayenne uses safety cell construction with a three-dimensional high-strength frame that surrounds the passenger compartment. It provides extra impact protection and a sturdy mounting location for door hardware and side impact beams. The LX570 uses a body-on-frame design, which has no frame members above the floor of the vehicle.

Both the Cayenne and the LX570 have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, traction control and electronic stability systems to prevent skidding.

J.D. Power and Associates rated the Cayenne third among midsize premium CUVs in their 2013 Initial Quality Study. The LX570 isn’t in the top three in its category.

J.D. Power and Associates’ 2013 Initial Quality Study of new car owners surveyed provide the statistics that show that Porsche vehicles are better in initial quality than Lexus vehicles. J.D. Power ranks Porsche first in initial quality, above the industry average. With 14 more problems per 100 vehicles, Lexus is ranked third.

The Cayenne S Hybrid’s standard 3.0 supercharged V6 hybrid produces 25 lbs.-ft. more torque (428 vs. 403) than the LX570’s 5.7 DOHC V8. The Cayenne S’ standard 4.8 DOHC V8 produces 17 more horsepower (400 vs. 383) than the LX570’s 5.7 DOHC V8. The Cayenne GTS’ standard 4.8 DOHC V8 produces 37 more horsepower (420 vs. 383) than the LX570’s 5.7 DOHC V8. The Cayenne Turbo S’ standard 4.8 turbo V8 produces 167 more horsepower (550 vs. 383) and 150 lbs.-ft. more torque (553 vs. 403) than the LX570’s 5.7 DOHC V8.

On the EPA test cycle the Cayenne Diesel gets better fuel mileage than the LX570 (20 city/29 hwy vs. 12 city/17 hwy).

On the EPA test cycle the Cayenne S Hybrid gets better fuel mileage than the LX570 (20 city/24 hwy vs. 12 city/17 hwy).

On the EPA test cycle the Cayenne S V8 gets better fuel mileage than the LX570 (16 city/22 hwy vs. 12 city/17 hwy).

Regenerative brakes improve the Cayenne Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The LX570 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Cayenne Automatic’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The LX570 doesn’t offer an automatic engine start/stop system.

The Cayenne has 1.8 gallons more fuel capacity than the LX570 (26.4 vs. 24.6 gallons), for longer range between fill-ups.

The Cayenne offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The LX570 doesn’t offer ceramic brake rotors.

The Cayenne stops much shorter than the LX570:

For better traction, the Cayenne’s optional tires are larger than the largest tires available on the LX570 (295/35R21 vs. 285/50R20).

The Cayenne’s optional tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the LX570’s 50 series tires.

For better ride, handling and brake cooling the Cayenne offers optional 21-inch wheels. The LX570’s largest wheels are only 20-inches.

For superior ride and handling, the Porsche Cayenne has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Lexus LX570 has a solid rear axle, with a non-independent rear suspension.

The Cayenne has standard front and rear gas-charged shocks for better control over choppy roads. The LX570’s suspension doesn’t offer gas-charged shocks.

The Cayenne (except Hybrid) offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The LX570 doesn’t offer an active sway bar system.

The Cayenne offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Lexus doesn’t offer an active suspension on the LX570.

For a smoother ride and more stable handling, the Cayenne’s wheelbase is 1.8 inches longer than on the LX570 (114 inches vs. 112.2 inches).

For better handling and stability, the track (width between the wheels) on the Cayenne is .6 inches wider in the front and 1.3 inches wider in the rear than on the LX570.

The Cayenne GTS handles at .95 G’s, while the LX570 pulls only .73 G’s of cornering force in a Car and Driver skidpad test.

For greater off-road capability the Cayenne Turbo has a 1.85 inches greater minimum ground clearance than the LX570 (10.75 vs. 8.9 inches), allowing the Cayenne to travel over rougher terrain without being stopped or damaged.

The Porsche Cayenne may be more efficient, handle and accelerate better because it weighs about 1050 to 1600 pounds less than the Lexus LX570.

The Cayenne is 6.2 inches shorter than the LX570, making the Cayenne easier to handle, maneuver and park in tight spaces.

The Cayenne is 8.6 inches shorter in height than the LX570, making the Cayenne much easier to wash and garage and drive (lower center of gravity).

Unibody construction makes the Cayenne’s chassis much stiffer, which contributes to better handling, and enables softer springs to be used for a better ride. Unibody construction’s stiffness also contributes to better durability and less body squeaks and rattles. The LX570 doesn’t use unibody construction, but a body-on-frame design.

A low lift-over cargo hatch design makes loading and unloading the Cayenne easier. The Cayenne’s cargo hatch lift-over height is 25.5 inches, while the LX570’s liftover is 28.8 inches.

The Cayenne’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The LX570’s tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.

Unlike the driver-only memory system in the LX570, the Cayenne offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position (with optional power wheel adjuster) and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The power windows standard on both the Cayenne and the LX570 have locks to prevent small children from operating them. When the lock on the Cayenne is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The LX570 prevents the driver from operating the other windows just as it does the other passengers.

Heated windshield washer nozzles are standard on the Cayenne to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The LX570 doesn’t offer heated windshield washer nozzles.

While driving with high beams on, sensitive light sensors available for the Cayenne detect other vehicles which could be blinded and automatically switch to low beams. The LX570 doesn’t offer automatic dimming high beams.

The Cayenne’s power mirror controls are mounted on the armrest for easy access. The LX570’s power mirror controls are on the dash, hidden behind the steering wheel, where they are awkward to manipulate.
