In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the LX are reminded to check the back seat if they opened the rear door before starting out. The Cayenne doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The LX has a standard Parking Support Brake that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Cayenne doesn’t offer backup collision prevention brakes.

The LX’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Cayenne.

The LX has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the Cayenne’s blind spot costs extra.

To help make backing out of a parking space safer, the LX’s standard Rear Cross-Traffic Alert uses sensors in the rear to alert the driver to vehicles approaching from the side and Parking Support Brake automatically engages the brakes to help avoid a collision. The Cayenne doesn’t offer a rear cross-path warning system.

The LX’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Cayenne doesn’t offer a driver alert monitor.

Both the LX and the Cayenne have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights and rearview cameras.

Warranty

Lexus’ powertrain warranty covers the LX 2 years and 20,000 miles longer than Porsche covers the Cayenne. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the Cayenne ends after only 4 years or 50,000 miles.

There are over 25 percent more Lexus dealers than there are Porsche dealers, which makes it easier should you ever need service under the LX’s warranty.

Reliability

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Lexus vehicles are better in initial quality than Porsche vehicles. J.D. Power ranks Lexus above average in initial quality. With 43 more problems per 100 vehicles, Porsche is rated below average.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Lexus vehicles are more reliable than Porsche vehicles. J.D. Power ranks Lexus above average in long-term dependability. With 33 more problems per 100 vehicles in the first three years of ownership, Porsche is rated lower.

Engine

The LX’s 3.4 turbo V6 produces 74 more horsepower (409 vs. 335) and 147 lbs.-ft. more torque (479 vs. 332) than the Cayenne’s standard 3.0 turbo V6. The LX’s 3.4 turbo V6 produces 74 lbs.-ft. more torque (479 vs. 405) than the Cayenne S’ standard 2.9 turbo V6. The LX’s 3.4 turbo V6 produces 22 lbs.-ft. more torque (479 vs. 457) than the Cayenne GTS’ standard 4.0 turbo V8.

Fuel Economy and Range

On the EPA test cycle the LX gets better mileage than the Cayenne running its gasoline engine:

			MPG
LX
	AWD	3.4 turbo V6	17 city/22 hwy
Cayenne
	AWD	2.9 turbo V6	16 city/22 hwy
		4.0 turbo V8 Hybrid	17 city/20 hwy
		GTS 4.0 turbo V8	15 city/19 hwy
		Turbo 4.0 turbo V8	14 city/19 hwy

The LX has 1.3 gallons more fuel capacity than the Cayenne E-Hybrid’s standard fuel tank (21.1 vs. 19.8 gallons), for longer range between fill-ups.

Environmental Friendliness

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Lexus LX higher (5 out of 10) than the Porsche Cayenne (3 to 5). This means the LX produces up to 16.5 pounds less smog-producing pollutants than the Cayenne every 15,000 miles.

Transmission

A 10-speed automatic is standard on the Lexus LX, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Cayenne.

Brakes and Stopping

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The LX has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Cayenne doesn’t offer a brake assist feature.

Tires and Wheels

For better traction, the LX has larger tires than the Cayenne (265/55R20 vs. 255/55R19).

The Lexus LX’s wheels have 6 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Porsche Cayenne only has 5 wheel lugs per wheel.

The LX has a standard full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the Cayenne; it requires you to depend on a temporary spare, which has mileage and speed limitations, or roadside assistance and a tow-truck.

Chassis

As tested by Car and Driver while at idle, the interior of the LX 600 F Sport is quieter than the Cayenne (37 vs. 40 dB).

Passenger Space

The LX offers optional seating for 8 passengers; the Cayenne can only carry 5.

Cargo Capacity

The LX’s cargo area provides more volume than the Cayenne.

	LX	Cayenne
Third Seat Folded	44 cubic feet	n/a
Third Seat Removed	n/a	27.2 cubic feet
Second Seat Folded	64 cubic feet	60.3 cubic feet

The LX’s cargo area is larger than the Cayenne’s in almost every dimension:

	LX 600 Ultra Luxury	LX	Cayenne
Length to seat (2nd/1st)	36.5”	10”/44.7”/66.5”	39.6”/74.9”
Max Width	51.8”	51.8”	42”
Min Width	41”	41.3”	42”
Height	39.8”	37.8”	30.4”

Pressing a switch automatically lowers or raises the LX Luxury’s second and third row seats, to make changing between cargo and passengers easier. The Cayenne doesn’t offer automatic folding second row seats.

Towing

The LX’s standard towing capacity is much higher than the Cayenne’s (8000 vs. 7700 pounds).

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Lexus service is better than Porsche. J.D. Power ranks Lexus first in service department satisfaction. With a 18% lower rating, Porsche is ranked third.

Ergonomics

The LX has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Cayenne doesn’t offer a remote starting system.

The LX’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Cayenne.

If the windows are left open on the LX the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. (This window function must be activated by your Lexus service department.) The driver of the Cayenne can only operate the windows from inside the vehicle, with the ignition on.

The LX’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Cayenne’s cruise control switches are unlit, making them difficult to find at night and operate safely.

To improve rear visibility by keeping the rear window clear, the LX has a standard rear fixed intermittent wiper with a full on position. The rear wiper standard on the Cayenne only has an intermittent setting, so in a hard rain visibility isn’t as good.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the LX has standard extendable sun visors. The Cayenne doesn’t offer extendable visors.

The LX has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel costs extra on the Cayenne.

Both the LX and the Cayenne offer available massaging front seats. The LX Ultra Luxury also has standard massaging second row seats in order to maximize comfort and eliminate fatigue on long trips. Massaging rear seats aren’t available in the Cayenne.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Lexus LX has a standard wireless phone charging system (Qi) in the center console and one for the rear passengers. Wireless charging costs extra on the Cayenne.

The LX has a 115-volt a/c outlet in the cargo area, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The Cayenne doesn’t offer a house-current electrical outlet.
