The A6 Allroad’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The RX doesn’t offer pre-crash pretensioners.

Both the A6 Allroad and RX have child safety locks to prevent children from opening the rear doors. The A6 Allroad 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’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 A6 Allroad has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The RX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A6 Allroad. But it costs extra on the RX.

A passive infrared night vision system optional on the A6 Allroad Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The RX doesn’t offer a night vision system.

Both the A6 Allroad and the RX have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front and rear seatbelt pretensioners, 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, rearview cameras, available blind spot warning systems and rear cross-path warning.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

Instrumented handling tests conducted by the National Highway Traffic Safety Administration and analysis of its dimensions indicate that the A6 Allroad, with its five-star roll-over rating, is 7.5% to 9% less likely to roll over than the RX, which received a four-star rating.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A6 Allroad its highest rating: “Top Pick Plus” for 2021, a rating granted to only 73 vehicles tested by the IIHS. The RX is only a standard “Top Pick” for 2021.

Warranty

The A6 Allroad’s corrosion warranty is 6 years longer than the RX’s (12 vs. 6 years).

There are over 24 percent more Audi dealers than there are Lexus dealers, which makes it easier should you ever need service under the A6 Allroad’s warranty.

Engine

The A6 Allroad’s 3.0 turbo V6 hybrid produces 40 more horsepower (335 vs. 295) and 101 lbs.-ft. more torque (369 vs. 268) than the RX 350’s standard 3.5 DOHC V6.

As tested in Motor Trend the Audi A6 Allroad is faster than the Lexus RX:

	A6 Allroad	RX 350	RX 450h
Zero to 60 MPH	5.1 sec	6.8 sec	7 sec
Quarter Mile	13.7 sec	15.1 sec	15.3 sec
Speed in 1/4 Mile	102.8 MPH	92.7 MPH	94.3 MPH

Fuel Economy and Range

On the EPA test cycle the A6 Allroad gets better mileage than the RX:

			MPG
A6 Allroad
	AWD	3.0 turbo V6 Hybrid	21 city/28 hwy
RX
	FWD	3.5 DOHC V6	20 city/27 hwy
	AWD	3.5 DOHC V6	19 city/26 hwy

Both the A6 Allroad and the RX Hybrid have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stop lights and heavy traffic. All A6 Allroads have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily.

The A6 Allroad has 2.1 gallons more fuel capacity than the RX Hybrid’s standard fuel tank (19.3 vs. 17.2 gallons), for longer range between fill-ups.

Transmission

The A6 Allroad offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The RX doesn’t offer an SMG or a conventional manual transmission.

The A6 Allroad’s launch control uses engine electronics to hold engine RPM’s precisely in order to provide the most stable and rapid acceleration possible, using all of the available traction. The RX doesn’t offer launch control.

Brakes and Stopping

For better stopping power the A6 Allroad’s front brake rotors are larger than those on the RX:

	A6 Allroad	RX
Front Rotors	14.8 inches	12.9 inches

The A6 Allroad stops shorter than the RX:

	A6 Allroad	RX
60 to 0 MPH	119 feet	123 feet	Motor Trend

Tires and Wheels

For better traction, the A6 Allroad has larger tires than the RX (245/45R20 vs. 235/65R18).

The A6 Allroad’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the RX’s standard 65 series tires. The A6 Allroad’s tires are lower profile than the RX’s optional 55 series tires.

For better ride, handling and brake cooling the A6 Allroad has standard 20-inch wheels. Smaller 18-inch wheels are standard on the RX.

Suspension and Handling

The front and rear suspension of the A6 Allroad uses air springs for a smoother, controlled ride than the RX, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The A6 Allroad has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The A6 Allroad’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 doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the A6 Allroad’s wheelbase is 5.4 inches longer than on the RX (115.2 inches vs. 109.8 inches).

The A6 Allroad Prestige handles at .82 G’s, while the RX 450h pulls only .78 G’s of cornering force in a Motor Trend skidpad test.

The A6 Allroad Prestige executes Motor Trend’s “Figure Eight” maneuver 1 seconds quicker than the RX 450h (26.5 seconds @ .68 average G’s vs. 27.5 seconds @ .65 average G’s).

For better maneuverability, the A6 Allroad Prestige w/All-Wheel Steering’s turning circle is 2.4 feet tighter than the RX’s (36.4 feet vs. 38.8 feet).

Chassis

The A6 Allroad is 8.8 inches shorter in height than the RX, making the A6 Allroad much easier to wash and garage and drive (lower center of gravity).

The design of the Audi A6 Allroad amounts to more than styling. The A6 Allroad has an aerodynamic coefficient of drag of .29 Cd. That is significantly lower than the RX (.33) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the A6 Allroad get better fuel mileage.

Cargo Capacity

The A6 Allroad has a much larger cargo volume with its rear seat up than the RX with its rear seat up (30 vs. 16 cubic feet). The A6 Allroad has a much larger cargo volume with its rear seat folded than the RX with its rear seat folded (63.8 vs. 32.6 cubic feet).

Servicing Ease

The engine in the A6 Allroad is mounted longitudinally (North-South), instead of sideways, as in the RX. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Ergonomics

Unlike the driver-only memory system optional at extra cost in the RX, the A6 Allroad Prestige offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle and climate settings and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The A6 Allroad’s headlights were rated “Good” to “Acceptable” by the IIHS, while the RX’s headlights are rated “Acceptable” to “Marginal.”

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A6 Allroad has standard headlight washers to keep headlight output high. The RX doesn’t offer headlight washers.

The A6 Allroad has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the car heater warms up. A heated steering wheel costs extra on the RX.

The A6 Allroad Prestige offers optional massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the RX.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Audi A6 Allroad has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the RX.

The A6 Allroad’s optional Park Steering Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The RX doesn’t offer an automated parking system.
