The Porsche Cayenne Coupe 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 XT5 doesn’t offer a front passenger side knee airbag.

The Cayenne Coupe 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 XT5 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 Coupe. But it costs extra on the XT5.

When descending a steep, off-road slope, the Cayenne Coupe’s standard Porsche Hill Control allows you to creep down safely. The XT5 doesn’t offer Porsche Hill Control.

Both the Cayenne Coupe and the XT5 have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, rearview cameras, available night vision systems, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The Cayenne Coupe’s corrosion warranty is 6 years longer than the XT5’s (12 vs. 6 years).

Reliability

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Cadillac vehicles. J.D. Power ranks Porsche above average in long-term dependability. With 30 more problems per 100 vehicles in the first three years of ownership, Cadillac is rated lower.

XT5 2.0 turbo 4-cylinder	235 HP	258 lbs.-ft.
XT5 3.6 DOHC V6	310 HP	271 lbs.-ft.

As tested in Motor Trend the Cayenne Turbo Coupe 4.0 turbo V8 is faster than the Cadillac XT5 V6:

	Cayenne Coupe	XT5
Zero to 60 MPH	3.2 sec	6.5 sec
Quarter Mile	11.7 sec	15.1 sec
Speed in 1/4 Mile	116.8 MPH	92.6 MPH

Fuel Economy and Range

On the EPA test cycle the Cayenne Coupe running on electricity gets better mileage than the XT5:

			MPGe
Cayenne Coupe
	AWD	E-Hybrid Coupe Electric Motor	45 city/48 hwy
		Turbo S E-Hybrid Coupe Electric Motor	40 city/44 hwy
XT5
			MPG
	FWD	3.6 DOHC V6	19 city/26 hwy
		2.0 turbo 4-cyl.	22 city/29 hwy
	AWD	3.6 DOHC V6	18 city/25 hwy
		2.0 turbo 4-cyl.	21 city/27 hwy

The Cayenne Coupe can travel with zero emissions for 15 to 17 miles (dependent on model). The XT5 can’t move without running its internal combustion engine.

Regenerative brakes improve the Cayenne Coupe’s fuel efficiency by converting inertia back into energy instead of wasting it. The XT5 doesn’t offer a regenerative braking system.

The Cayenne Coupe’s standard fuel tank has 2 gallons more fuel capacity than the XT5 AWD’s standard fuel tank (23.7 vs. 21.7 gallons).

Transmission

The Cayenne Coupe’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 XT5 doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Cayenne Coupe’s brake rotors are larger than those on the XT5:

	Cayenne E-Hybrid Coupe	Cayenne Coupe CCB	XT5
Front Rotors	14.2 inches	17.3 inches	13.6 inches
Rear Rotors	14.1 inches	16.1 inches	12.4 inches

The Cayenne Coupe 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 XT5 doesn’t offer ceramic brake rotors.

The Cayenne Coupe Turbo has standard air brakes, which adjust the spoiler automatically during high-speed braking in order to shorten stopping distances. The XT5 doesn’t offer air brakes.

The Cayenne Coupe stops much shorter than the XT5:

	Cayenne Coupe	XT5
70 to 0 MPH	154 feet	174 feet	Car and Driver
60 to 0 MPH	100 feet	128 feet	Motor Trend

Tires and Wheels

For better traction, the Cayenne Coupe has larger standard tires than the XT5 (F:275/45R20 & R:305/40R20 vs. 235/65R18). The Cayenne Coupe’s optional tires are larger than the largest tires available on the XT5 (F:285/40R21 & R:315/35R21 vs. 235/65R18).

The Cayenne Coupe’s standard 275/45R20 front and 305/40R20 rear tires provide better handling because they have a lower 45 series front and 40 series rear profile (height to width ratio) that provides a stiffer sidewall than the XT5’s standard 65 series tires. The Cayenne Coupe’s optional 285/35R22 front and 315/30R22 rear tires have a lower 35 series front and 30 series rear profile than the XT5’s optional 55 series tires.

For better ride, handling and brake cooling the Cayenne Coupe has standard 20-inch wheels. Smaller 18-inch wheels are standard on the XT5. The Cayenne Coupe’s optional 22-inch wheels are larger than the 20-inch wheels optional on the XT5.

Suspension and Handling

The Cayenne Coupe 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 XT5 doesn’t offer an active sway bar system.

The Cayenne Coupe offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Cadillac doesn’t offer an active suspension on the XT5.

The Cayenne Coupe has a standard automatic load leveling suspension to keep ride height level with a heavy load or when towing. The XT5 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Cayenne Coupe’s wheelbase is 1.5 inches longer than on the XT5 (114 inches vs. 112.5 inches).

For better handling and stability, the average track (width between the wheels) on the Cayenne Coupe is 1.4 inches wider in the front and 1.4 inches wider in the rear than the track on the XT5.

The Cayenne Turbo GT handles at 1.03 G’s, while the XT5 AWD pulls only .84 G’s of cornering force in a Car and Driver skidpad test.

The Cayenne Turbo Coupe executes Motor Trend’s “Figure Eight” maneuver 3 seconds quicker than the XT5 AWD (24.1 seconds @ .82 average G’s vs. 27.1 seconds @ .65 average G’s).

For better maneuverability, the Cayenne Coupe w/Rear Wheel Steering’s turning circle is 3.6 feet tighter than the XT5’s (35.1 feet vs. 38.7 feet).

For greater off-road capability the Cayenne Coupe has a greater minimum ground clearance than the XT5 (8.2 vs. 7.8 inches), allowing the Cayenne Coupe to travel over rougher terrain without being stopped or damaged. The Cayenne Coupe Air Suspension’s minimum ground clearance is 1.8 inches higher than on the XT5 (9.6 vs. 7.8 inches).

Chassis

As tested by Car and Driver while at idle, the interior of the Cayenne Turbo GT is quieter than the XT5 AWD (43 vs. 44 dB).

Passenger Space

The Cayenne Coupe has .8 inches more front shoulder room, 1 inch more rear legroom and .2 inches more rear shoulder room than the XT5.

Towing

The Cayenne Coupe’s standard towing capacity is much higher than the XT5’s (7700 vs. 1000 pounds).

Servicing Ease

The engine in the Cayenne Coupe is mounted longitudinally (North-South), instead of sideways, as in the XT5. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Ergonomics

Unlike the driver-only memory system in the XT5 Premium Luxury/Sport, the Cayenne Coupe offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle and climate settings and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Cayenne Coupe’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The XT5’s rear power window switches have to be held the entire time to close them fully.

The Cayenne Coupe has a standard locking fuel and charge port door with a remote release located convenient to the driver. A locking fuel door helps prevent fuel theft and vandalism, such as sugar in the tank. The XT5 doesn’t offer a locking fuel door.

The Cayenne Coupe’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 XT5’s standard manually variable intermittent wipers have to be constantly adjusted.

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 Coupe offers available headlight washers to keep headlight output high. The XT5 doesn’t offer headlight washers.

The XT5’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The Cayenne Coupe’s optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

To better shield the driver and front passenger’s vision, the Cayenne Coupe has standard dual-element sun visors that can block glare from two directions simultaneously. The XT5 doesn’t offer secondary sun visors.

Manual rear side window sunshades are available in the Cayenne Coupe to help block heat and glare for the rear passengers. The XT5 doesn’t offer rear side window sunshades.

The Cayenne Coupe offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the XT5.

The Cayenne Coupe’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 XT5 Premium Luxury/Sport’s automatic parking system does not offer parking by remote control.

Economic Advantages

The Cayenne Coupe will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the Cayenne Coupe will retain 47.15% to 59.53% of its original price after five years, while the XT5 only retains 42.02% to 43.14%.
