Compare the2024 Jaguar E-PaceVS 2023 Porsche Cayenne Coupe

Both the E-Pace and Cayenne Coupe have child safety locks to prevent children from opening the rear doors. The E-Pace 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.

Using vehicle speed sensors and seat sensors, smart airbags in the E-Pace deploy with different levels of force to help better protect passengers of all sizes in different collisions. The E-Pace’s side airbags will shut off if a child is leaning against the door. The Cayenne Coupe’s side airbags don’t have smart features and will always deploy full force.

The E-Pace’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 E-Pace has a standard blind spot warning system that 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 E-Pace’s standard Rear Traffic Warning uses sensors in the rear to alert the driver to vehicles approaching from the side and Rear Traffic Braking automatically engages the brakes to help avoid a collision. The Cayenne Coupe doesn’t offer a rear cross-path warning system.

The E-Pace’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 E-Pace 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, rearview cameras and available around view monitors.

The E-Pace comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Cayenne Coupe’s 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Jaguar pays for scheduled maintenance on the E-Pace for 4 years and 50,000 miles longer than Porsche pays for maintenance for the Cayenne Coupe (5/60,000 vs. 1/10,000).

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

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

A nine-speed automatic is standard on the Jaguar E-Pace, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Cayenne Coupe.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The E-Pace has 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 Jaguar E-Pace may be more efficient, handle and accelerate better because it weighs about 750 to 1750 pounds less than the Porsche Cayenne Coupe.

The E-Pace is 1 foot, 9.2 inches shorter than the Cayenne Coupe, making the E-Pace easier to handle, maneuver and park in tight spaces.

The design of the Jaguar E-Pace amounts to more than styling. The E-Pace has an aerodynamic coefficient of drag of .33 Cd. That is lower than the Cayenne Coupe (.34 to .35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the E-Pace get better fuel mileage.

As tested by Car and Driver while under full throttle, the interior of the E-Pace SE is quieter than the Cayenne Turbo GT (76 vs. 83 dB).

The E-Pace has a larger cargo volume than the Cayenne Coupe with its rear seat up (22.4 vs. 22 cubic feet).

The E-Pace 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.

The E-Pace’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Cayenne Coupe.

On a hot day the E-Pace’s driver can lower all the windows from a distance using the keyless remote. The driver of the Cayenne Coupe can only operate the windows from inside the vehicle, with the ignition on.

The E-Pace’s power window, power lock and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Cayenne Coupe’s cruise control switches are unlit, making them difficult to find at night and operate safely.

Heated windshield washer nozzles are optional on the E-Pace 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 E-Pace has a standard rear wiper. The Cayenne Coupe doesn’t offer a rear wiper.

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