For enhanced safety, the front seat shoulder belts of the Porsche Cayenne Coupe are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The Jaguar I-Pace doesn’t offer height-adjustable seat belts.
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 I-Pace 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.
When descending a steep, off-road slope, the Cayenne Coupe’s standard Porsche Hill Control allows you to creep down safely. The I-Pace doesn’t offer Porsche Hill Control.
A passive infrared night vision system optional on the Cayenne Coupe helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The I-Pace doesn’t offer a night vision system.
Both the Cayenne Coupe and the I-Pace have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
The Cayenne Coupe’s corrosion warranty is 6 years longer than the I-Pace’s (12 vs. 6 years).
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 Coupe’s reliability 51 points higher than the I-Pace.
J.D. Power and Associates’ 2019 Initial Quality Study of new car owners surveyed provide the statistics that show that Porsche vehicles are better in initial quality than Jaguar vehicles. J.D. Power ranks Porsche 15th in initial quality. With 27 more problems per 100 vehicles, Jaguar is ranked 31st.
J.D. Power and Associates’ 2019 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Jaguar vehicles. J.D. Power ranks Porsche second in reliability, above the industry average. With 60 more problems per 100 vehicles, Jaguar is ranked 25th.
The Cayenne S Coupe’s standard 2.9 turbo V6 produces 40 more horsepower (434 vs. 394) than the I-Pace’s electric motors. The Cayenne E-Hybrid Coupe’s standard 3.0 turbo V6 hybrid produces 61 more horsepower (455 vs. 394) and 4 lbs.-ft. more torque (516 vs. 512) than the I-Pace’s electric motors. The Cayenne Turbo Coupe’s standard 4.0 turbo V8 produces 147 more horsepower (541 vs. 394) and 56 lbs.-ft. more torque (568 vs. 512) than the I-Pace’s electric motors. The Cayenne Turbo S E-Hybrid Coupe’s standard 4.0 turbo V8 hybrid produces 276 more horsepower (670 vs. 394) and 151 lbs.-ft. more torque (663 vs. 512) than the I-Pace’s electric motors.
The Cayenne Coupe’s maximum EPA estimated driving range on a full tank of fuel and a full charge is 545.1 miles, after which it can be refueled at any gas station in minutes. The I-Pace’s range is only 234 miles, after which the minimum recharge time is 1 hour and 25 minutes for only an 80% charge at a specially configured quick charge station not available in most areas. A full recharge at a conventional charging station can take up to 12 hours and 54 minutes.
For better stopping power the Cayenne Coupe’s brake rotors are larger than those on the I-Pace:
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 I-Pace 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 I-Pace doesn’t offer air brakes.
For better traction, the Cayenne Coupe has larger standard tires than the I-Pace (F:275/45R20 & R:305/40R20 vs. 235/65R18). The Cayenne Coupe’s optional tires are larger than the largest tires available on the I-Pace (F:285/40R21 & R:315/35R21 vs. 255/40R22).
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 I-Pace’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 I-Pace’s optional 40 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 I-Pace.
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 I-Pace 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. Jaguar doesn’t offer an active suspension on the I-Pace.
For better handling and stability, the average track (width between the wheels) on the Cayenne Coupe is 1.9 inches wider in the front and 1 inch wider in the rear than the average track on the I-Pace.
For greater off-road capability the Cayenne Coupe has a greater minimum ground clearance than the I-Pace (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 I-Pace (9.6 vs. 7.8 inches).
For enhanced passenger comfort on long trips the Cayenne Coupe’s rear seats recline. The I-Pace’s rear seats don’t recline.
The Cayenne Coupe has a larger cargo volume with its rear seat folded than the I-Pace with its rear seat folded (54.3 vs. 52 cubic feet).
The Cayenne Coupe’s standard towing capacity is much higher than the I-Pace’s (7700 vs. 1653 pounds).
J.D. Power and Associates surveys of service recipients show that Porsche service is better than Jaguar. J.D. Power ranks Porsche first in service department satisfaction. With a 68% lower rating, Jaguar is ranked 20th.
To help drivers see further while navigating curves, the Cayenne Coupe offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The I-Pace doesn’t offer cornering lights.
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 I-Pace.
