Compare the2024 Porsche CayenneVS 2024 Jeep Grand Cherokee

The Cayenne has a standard Multi-collision Brake System, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Grand Cherokee doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Cayenne. But it costs extra on the Grand Cherokee.

Both the Cayenne and Grand Cherokee have rear cross-traffic warning, but the Cayenne has Rear Cross Traffic Alert (automatically applies the brakes) to better prevent a collision when backing near traffic. The Grand Cherokee’s Rear Cross Path Detection doesn’t automatically brake.

Both the Cayenne and the Grand Cherokee have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available night vision systems and around view monitors.

The Cayenne comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Grand Cherokee’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The Cayenne’s corrosion warranty is 7 years longer than the Grand Cherokee’s (12 vs. 5 years).

The Cayenne has more powerful engines than the Grand Cherokee:

Regardless of its engine, regenerative brakes improve the Cayenne’s fuel efficiency by converting inertia back into energy instead of wasting it. Jeep only offers a regenerative brake system on the Grand Cherokee 4xe.

Both the Cayenne and the Grand Cherokee have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. All Cayenne’s have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. A disable switch for start/stop is only offered on the Grand Cherokee V6.

The Cayenne has a standard locking fuel door which locks and unlocks with the power locks. The fuel filler door is not lockable on the Grand Cherokee. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank.

The Cayenne’s optional launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The Grand Cherokee doesn’t offer launch control.

For better stopping power the Cayenne’s front brake rotors are larger than those on the Grand Cherokee:

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 Grand Cherokee doesn’t offer ceramic brake rotors.

The Cayenne Turbo has standard air brakes, which adjust the spoiler automatically during high-speed braking in order to shorten stopping distances. The Grand Cherokee doesn’t offer air brakes.

For better traction, the Cayenne has larger standard tires than the Grand Cherokee (F:255/55R20 & R:295/45R20 vs. 245/70R17). The Cayenne’s optional tires are larger than the largest tires available on the Grand Cherokee (F:285/45R21 & R:315/40R21 vs. 275/45R21).

The Cayenne’s standard 255/55R20 front and 295/45R20 rear tires provide better handling because they have a lower 55 series front and 45 series rear profile (height to width ratio) that provides a stiffer sidewall than the Grand Cherokee Laredo’s standard 70 series tires. The Cayenne’s optional 285/40R22 front and 315/35R22 rear tires have a lower 40 series front and 35 series rear profile than the Grand Cherokee Summit Reserve’s 45 series tires.

For better ride, handling and brake cooling the Cayenne has standard 20-inch wheels. Smaller 17-inch wheels are standard on the Grand Cherokee Laredo. The Cayenne’s optional 22-inch wheels are larger than the 21-inch wheels on the Grand Cherokee Summit Reserve.

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

The front step up height for the Cayenne is 3.5 inches lower than the Grand Cherokee (16.75” vs. 20.2”). The Cayenne’s rear step up height is 5.5 inches lower than the Grand Cherokee’s (16” vs. 21.5”).

A low lift-over cargo hatch design makes loading and unloading the Cayenne easier. The Cayenne’s cargo hatch lift-over height is 31 inches, while the Grand Cherokee’s liftover is 33 inches.

The Cayenne’s standard towing capacity is much higher than the Grand Cherokee’s (7700 vs. 3500 pounds).

The Cayenne has a higher standard payload capacity than the Grand Cherokee (1424 vs. 1243 lbs.).

The Cayenne has a much higher maximum payload capacity than the Grand Cherokee (1601 vs. 1283 lbs.).

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Jeep. J.D. Power ranks Porsche third in service department satisfaction. With a 45% lower rating, Jeep is ranked 26th.

The Cayenne’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Grand Cherokee’s standard rear power window switches have to be held the entire time to open or close them fully.

The Cayenne’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Grand Cherokee’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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 Grand Cherokee doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Cayenne offers available headlight washers to keep headlight output high. The Grand Cherokee doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the Cayenne offers optional cornering lights to illuminate around corners when the turn signals are activated. The Grand Cherokee doesn’t offer cornering lights. The Cayenne also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

To better shield the driver and front passenger’s vision, the Cayenne has standard dual-element sun visors that can block glare from two directions simultaneously. The Grand Cherokee doesn’t offer secondary sun visors.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Porsche Cayenne has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Grand Cherokee and isn’t available on the Grand Cherokee Laredo A.

The Cayenne’s optional Active Parking Assistance can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote ParkAssist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Grand Cherokee Summit’s automatic parking system requires operating the brakes and transmission to safely park and it doesn’t offer remote control parking.

Consumer Reports® recommends the Porsche Cayenne, based on reliability, safety and performance. The Jeep Grand Cherokee isn't recommended.
