2015 Porsche Cayenne

Safety Comparison

The Range Rover Sport’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Cayenne doesn’t offer pre-crash pretensioners.

Both the Range Rover Sport and Cayenne have child safety locks to prevent children from opening the rear doors. The Range Rover Sport has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Cayenne’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

To help make backing safer, the Range Rover Sport’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Cayenne doesn’t offer a cross-path warning system.

Both the Range Rover Sport and the Cayenne have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, front parking sensors, available crash mitigating brakes, lane departure warning systems, blind spot warning systems and around view monitors.

Fuel Economy and Range Comparison

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

The Range Rover Sport has 6.6 gallons more fuel capacity than the Cayenne S E-Hybrid’s standard fuel tank (27.7 vs. 21.1 gallons), for longer range between fill-ups. The Range Rover Sport has 1.3 gallons more fuel capacity than the Cayenne’s standard fuel tank (27.7 vs. 26.4 gallons).

Tires and Wheels Comparison

The Range Rover Sport’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Cayenne’s standard 55 series tires.

For better ride, handling and brake cooling the Range Rover Sport has standard 19-inch wheels. Smaller 18-inch wheels are standard on the Cayenne. The Range Rover Sport’s optional 22-inch wheels are larger than the 21-inch wheels optional on the Cayenne.

Suspension and Handling Comparison

The front and rear suspension of the Range Rover Sport uses air springs for a smoother, controlled ride than the Cayenne, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The Range Rover Sport has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Range Rover Sport’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Cayenne doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Range Rover Sport’s wheelbase is 1.1 inches longer than on the Cayenne (115.1 inches vs. 114 inches).

For better handling and stability, the track (width between the wheels) on the Range Rover Sport is 1.5 inches wider in the front and .8 inches wider in the rear than the average track on the Cayenne.

The Range Rover Sport Supercharged handles at .86 G’s, while the Cayenne Diesel pulls only .85 G’s of cornering force in a Motor Trend skidpad test.

The Range Rover Sport Supercharged executes Motor Trend’s “Figure Eight” maneuver 1.3 seconds quicker than the Cayenne Diesel (25.8 seconds @ .71 average G’s vs. 27.1 seconds @ .64 average G’s).

For greater off-road capability the Range Rover Sport has a 2.5 inches greater minimum ground clearance than the Cayenne (11 vs. 8.5 inches), allowing the Range Rover Sport to travel over rougher terrain without being stopped or damaged. The Range Rover Sport’s minimum ground clearance is .25 inch higher than on the Cayenne Turbo (11 vs. 10.75 inches).

Passenger Space Comparison

The Range Rover Sport offers optional seating for 7 passengers; the Cayenne can only carry 5.

Cargo Capacity Comparison

The Range Rover Sport has a much larger cargo area than the Cayenne with its rear seat up (27.7 vs. 23.7 cubic feet).

Ergonomics Comparison

The Range Rover Sport’s standard easy entry system raises the steering wheel, 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 down on the Range Rover Sport the driver can raise them all using the key in the outside lock cylinder or the keyless remote; on a hot day the driver can lower the windows. The driver of the Cayenne can only operate the windows from inside the vehicle, with the ignition on.

To improve rear visibility by keeping the rear window clear, the Range Rover Sport 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.

When the Range Rover Sport is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Cayenne’s mirrors don’t automatically adjust for backing.

Standard InControl Apps for the Range Rover Sport allows the driver and passengers access to select programs on their smartphones, including playing internet radio stations and other connected activities without taking their eyes off the road or their hands from the wheel. The Cayenne doesn’t offer factory integrated smartphone program access.

The Range Rover Sport’s optional Advanced Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Cayenne doesn’t offer an automated parking system.
