Safety

Both the e-tron and RXL have child safety locks to prevent children from opening the rear doors. The e-tron 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 RXL’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 allow off-road and deep snow capability, Four-Wheel Drive is standard on the e-tron. But it costs extra on the RXL.

An active infrared night vision system optional on the e-tron helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera and near-infrared lights to detect heat, the system then displays the image on a monitor in the dashboard. The RXL doesn’t offer a night vision system.

Both the e-tron and the RXL have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems and rearview cameras.

Warranty

The e-tron’s corrosion warranty is 6 years longer than the RXL’s (12 vs. 6 years).

There are over 26 percent more Audi dealers than there are Lexus dealers, which makes it easier should you ever need service under the e-tron’s warranty.

Engine

The e-tron’s electric motor produces 112 more horsepower (402 vs. 290) and 227 lbs.-ft. more torque (490 vs. 263) than the RX 350L’s standard 3.5 DOHC V6. The e-tron’s electric motor produces 94 more horsepower (402 vs. 308) than the RX 450hL’s standard 3.5 DOHC V6 hybrid.

Fuel Economy and Range

On the EPA test cycle the e-tron gets better fuel mileage than the RX 450hL (74 city/73 hwy MPGe vs. 29 city/28 hwy).

Brakes and Stopping

For better stopping power the e-tron’s brake rotors are larger than those on the RXL:

Tires and Wheels

For better traction, the e-tron has larger standard tires than the RXL (255/50R20 vs. 235/65R18). The e-tron Prestige’s optional tires are larger than the largest tires available on the RXL (265/45R21 vs. 235/65R18).

The e-tron’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 RXL’s standard 65 series tires. The e-tron Prestige’s optional tires have a lower 45 series profile than the RXL’s optional 55 series tires.

For better ride, handling and brake cooling the e-tron has standard 20-inch wheels. Smaller 18-inch wheels are standard on the RXL. The e-tron Prestige’s optional 21-inch wheels are larger than the 20-inch wheels optional on the RXL.

Suspension and Handling

The front and rear suspension of the e-tron uses air springs for a smoother, controlled ride than the RXL, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The e-tron has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The e-tron’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 RXL doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the e-tron’s wheelbase is 5.5 inches longer than on the RXL (115.3 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the e-tron is .8 inches wider in the front and 1.2 inches wider in the rear than on the RXL.

Chassis

The e-tron is 3.9 inches shorter than the RXL, making the e-tron easier to handle, maneuver and park in tight spaces.

The design of the Audi e-tron amounts to more than styling. The e-tron has an aerodynamic coefficient of drag of .3 Cd. That is lower than the RXL (.33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the e-tron get better fuel mileage.

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

Passenger Space

The e-tron has .3 inches more front shoulder room, .1 inches more rear headroom and 8.2 inches more rear legroom than the RXL.

Towing

Maximum trailer towing in the Lexus RXL is limited to 3500 pounds. The e-tron offers up to a 4000 lbs. towing capacity.

Ergonomics

Unlike the driver-only memory system in the RXL, the e-tron Prestige has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.
