Both the I-Pace and RX Series have child safety locks to prevent children from opening the rear doors. The I-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 RX Series’ 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 provide maximum traction and stability on all roads, All-Wheel Drive is standard on the I-Pace. But it costs extra on the RX Series.

Both the I-Pace and the RX Series have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras, driver alert monitors, available blind spot warning systems and around view monitors.

Jaguar pays for scheduled maintenance on the I-Pace for 4 years and 50,000 miles longer than Lexus pays for maintenance for the RX Series (5/60,000 vs. 1/10,000).

The I-Pace’s electric motors produce 99 more horsepower (394 vs. 295) and 244 lbs.-ft. more torque (512 vs. 268) than the RX 350’s standard 3.5 DOHC V6. The I-Pace’s electric motors produce 86 more horsepower (394 vs. 308) than the RX 450h’s standard 3.5 DOHC V6 hybrid.

Tires and Wheels

For better traction, the I-Pace’s optional tires are larger than the largest tires available on the RX Series (255/40R22 vs. 235/65R18).

The I-Pace’s optional tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the RX Series’ optional 55 series tires.

For better ride, handling and brake cooling the I-Pace offers optional 22-inch wheels. The RX Series’ largest wheels are only 20-inches.

Suspension and Handling

The front and rear suspension of the I-Pace uses air springs for a smoother, controlled ride than the RX Series, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The I-Pace has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The I-Pace’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 RX Series doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the I-Pace’s wheelbase is 7.9 inches longer than on the RX Series (117.7 inches vs. 109.8 inches).

For better handling and stability, the average track (width between the wheels) on the I-Pace is 1.1 inches wider in the rear than the track on the RX Series.

The I-Pace’s front to rear weight distribution is more even (50% to 50%) than the RX Series’ (57% to 43%). This gives the I-Pace more stable handling and braking.

The I-Pace HSE handles at .93 G’s, while the RX 450h pulls only .78 G’s of cornering force in a Motor Trend skidpad test.

The I-Pace HSE executes Motor Trend’s “Figure Eight” maneuver 2.7 seconds quicker than the RX 450h (24.8 seconds @ .77 average G’s vs. 27.5 seconds @ .65 average G’s).

The I-Pace is 8.2 inches shorter than the RX Series, making the I-Pace easier to handle, maneuver and park in tight spaces.

The design of the Jaguar I-Pace amounts to more than styling. The I-Pace has an aerodynamic coefficient of drag of .29 Cd. That is significantly lower than the RX Series (.33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the I-Pace get better fuel mileage.

The front grille of the I-Pace uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The RX Series doesn’t offer active grille shutters.

Unlike the driver-only memory system optional in the RX Series, the I-Pace offers an optional driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

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

The I-Pace’s Park Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The RX Series doesn’t offer an automated parking system.

J.D. Power and Associates rated the I-Pace second among compact premium SUVs in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The RX Series isn’t in the top three in its category.
