Both the Discovery and Cayenne Coupe have child safety locks to prevent children from opening the rear doors. The Discovery 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 Coupe’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.

The Discovery’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Cayenne Coupe.

The Discovery has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Cayenne Coupe’s blind spot costs extra.

To help make backing out of a parking space safer, the Discovery has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the Cayenne Coupe.

The Discovery’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Cayenne Coupe doesn’t offer a driver alert monitor.

Both the Discovery and the Cayenne Coupe 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 and rearview cameras.

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

The Discovery has 4 gallons more fuel capacity than the Cayenne Coupe E-Hybrid’s standard fuel tank (23.8 vs. 19.8 gallons), for longer range between fill-ups.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Land Rover Discovery higher (7 out of 10) than the Porsche Cayenne Coupe (3 to 5). This means the Discovery produces up to 24.5 pounds less smog-producing pollutants than the Cayenne Coupe every 15,000 miles.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The Discovery has a standard Emergency Brake Assist to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Cayenne Coupe doesn’t offer a brake assist feature.

The Discovery offers an optional full size spare tire so a flat doesn’t interrupt your trip. A full size spare isn’t available on the Cayenne Coupe; it requires you to depend on a temporary spare, which has mileage and speed limitations, or roadside assistance and a tow-truck.

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

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

For greater off-road capability the Discovery has a 2.9 inches greater minimum ground clearance than the Cayenne Coupe (11.1 vs. 8.2 inches), allowing the Discovery to travel over rougher terrain without being stopped or damaged. The Discovery’s minimum ground clearance is 1.5 inches higher than on the Cayenne Coupe Air Suspension (11.1 vs. 9.6 inches).

The Discovery has standard seating for 7 passengers; the Cayenne Coupe can only carry up to 5.

The Discovery has 1.2 inches more front headroom, 1.3 inches more front shoulder room, .7 inches more rear headroom and 3 inches more rear shoulder room than the Cayenne Coupe.

Flexibility is maximized at the game, campground or a drive-in theatre in the Discovery when its optional tailgating rear seats are deployed, allowing people to sit facing out of the liftgate. (Do not use while vehicle is in motion.) The Cayenne Coupe doesn’t offer tailgating seats.

The Discovery’s cargo area provides more volume than the Cayenne Coupe.

Pressing a button automatically lowers or raises the Discovery’s second and third row seats, to make changing between cargo and passengers easier. The Cayenne Coupe doesn’t offer automatic folding second row seats.

Maximum trailer towing in the Porsche Cayenne Coupe is limited to 7700 pounds. The Discovery offers up to a 8200 lbs. towing capacity.

The Discovery has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Cayenne Coupe doesn’t offer a remote starting system.

Heated windshield washer nozzles are optional on the Discovery to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Cayenne Coupe doesn’t offer heated windshield washer nozzles.

To improve rear visibility by keeping the rear window clear, the Discovery has a standard rear wiper. The Cayenne Coupe doesn’t offer a rear wiper.

The Discovery HSE/Metropolitan has standard front air conditioned seats and the Discovery offers them optionally in the second row. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The Cayenne Coupe doesn’t offer air-conditioned seats in the rear.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Land Rover Discovery has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Cayenne Coupe.
