Compare the2024 Jaguar E-PaceVS 2024 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 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, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning 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:

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 800 to 1800 pounds less than the Porsche Cayenne Coupe.

The E-Pace is 1 foot, 9 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 S Coupe (76 vs. 77 dB).

The E-Pace has a much larger cargo volume than the Cayenne Coupe with its rear seat up (22.4 vs. 20.9 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 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.

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.

Insurance will cost less for the E-Pace owner. The Complete Car Cost Guide estimates that insurance for the E-Pace will cost $6325 to $13440 less than the Cayenne Coupe over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Jaguar E-Pace will be $30321 to $122192 less than for the Porsche Cayenne Coupe.
