Compare the2022 Porsche CayenneVS 2021 Bentley Bentayga

The Porsche Cayenne has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Bentayga doesn’t offer knee airbags.

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 Bentayga 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.

The Cayenne has standard Porsche Connect, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Bentayga doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Cayenne and the Bentayga have standard driver and passenger frontal airbags, front and rear side-impact 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, daytime running lights, rearview cameras, available night vision systems, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

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 Bentayga’s 3-year basic warranty expires 1 year sooner.

The Cayenne’s corrosion warranty is 9 years longer than the Bentayga’s (12 vs. 3 years).

There are over 4 times as many Porsche dealers as there are Bentley dealers, which makes it much easier should you ever need service under the Cayenne’s warranty.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Cayenne’s reliability 25 points higher than the Bentayga.

The Cayenne Turbo S E-Hybrid’s 4.0 turbo V8 hybrid produces 44 more horsepower (670 vs. 626) than the Bentayga SPEED’s optional 6.0 turbo 12-cylinder.

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

Regardless of its engine, regenerative brakes improve the Cayenne’s fuel efficiency by converting inertia back into energy instead of wasting it. Bentley only offers a regenerative brake system on the Bentayga Hybrid.

Both the Cayenne and the Bentayga have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stop lights 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.

The Cayenne’s standard fuel tank has 1.2 gallons more fuel capacity than the Bentayga’s standard fuel tank (23.7 vs. 22.5 gallons).

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 Bentayga doesn’t offer launch control.

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

The Cayenne stops much shorter than the Bentayga:

The Cayenne’s optional 285/35R22 front and 315/30R22 rear tires provide better handling because they have a lower 35 series front and 30 series rear profile (height to width ratio) that provides a stiffer sidewall than the Bentayga’s optional 40 series tires.

The Cayenne handles at .96 G’s, while the Bentayga pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

The Cayenne Turbo executes Motor Trend’s “Figure Eight” maneuver 1.7 seconds quicker than the Bentayga (23.9 seconds @ .83 average G’s vs. 25.6 seconds @ .74 average G’s).

For better maneuverability, the Cayenne w/Rear Wheel Steering’s turning circle is 3.9 feet tighter than the Bentayga SPEED’s (35.1 feet vs. 39 feet). The Cayenne’s turning circle is .8 feet tighter than the Bentayga’s (39.8 feet vs. 40.6 feet).

The Porsche Cayenne may be more efficient, handle and accelerate better because it weighs about 150 to 750 pounds less than the Bentley Bentayga.

The Cayenne is 8.1 inches shorter than the Bentayga, making the Cayenne easier to handle, maneuver and park in tight spaces.

The front grille of the Cayenne uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Bentayga doesn’t offer active grille shutters.

The Cayenne has .4 inches more front shoulder room and 1 inch more rear headroom than the Bentayga.

The Cayenne has a much larger cargo volume than the Bentayga with its rear seat up (27.2 vs. 17.1 cubic feet).

The Cayenne’s standard rear seats fold to accommodate long and bulky cargo. The Bentayga w/Four Seat Comfort Specification doesn’t offer folding rear seats, only a ski pass-through.

A trailer sway program standard on the Cayenne, using the Porsche Stability Management sensors to detect trailer sway, then uses individual brakes to counteract any swaying and help keep the tow vehicle and trailer steady. A trailer sway program costs extra on the Bentayga.

The Cayenne’s instruments include an oil pressure gauge and a temperature gauge - which could save your engine! Often ‘idiot lights’ don’t warn you until damage has been done. The Bentayga does not have an oil pressure gauge.

The Cayenne’s optional Active Park Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Park Assist will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Bentayga’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.
