Compare the2024 Audi A4 AllroadVS 2022 Lexus RX

The A4 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 A4 Allroad and RX have child safety locks to prevent children from opening the rear doors. The A4 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 A4 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 A4 Allroad. But it costs extra on the RX.

Both the A4 Allroad and the RX have standard driver and passenger frontal airbags, front 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, around view monitors and rear cross-path warning.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a post at 20 MPH, results indicate that the Audi A4 Allroad is safer than the Lexus RX:

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

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 front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the A4 Allroad its highest rating: “Top Safety Pick Plus” for 2019, a rating granted to only 135 vehicles tested by the IIHS. The RX is only a standard “Top Safety Pick” for 2019.

The A4 Allroad’s corrosion warranty is 6 years longer than the RX’s (12 vs. 6 years).

There are over 25 percent more Audi dealers than there are Lexus dealers, which makes it easier should you ever need service under the A4 Allroad’s warranty.

The Audi A4 Allroad’s engine uses a cast iron block for durability, while the RX’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

The A4 Allroad’s 2.0 turbo 4-cylinder hybrid produces 5 lbs.-ft. more torque (273 vs. 268) than the RX 350’s standard 3.5 DOHC V6.

On the EPA test cycle the A4 Allroad gets better mileage than the RX:

Both the A4 Allroad and the RX 450h have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. All A4 Allroads have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily.

To lower fuel costs and make buying fuel easier, the Audi A4 Allroad uses regular unleaded gasoline (premium recommended for maximum performance). The RX 450h requires premium, which can cost on average about 82.8 cents more per gallon.

The A4 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 A4 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.

For better stopping power the A4 Allroad’s front brake rotors are larger than those on the RX:

The A4 Allroad stops much shorter than the RX:

For better traction, the A4 Allroad has larger tires than the RX (245/45R18 vs. 235/65R18).

The A4 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 A4 Allroad’s tires are lower profile than the RX’s optional 55 series tires.

For a smoother ride and more stable handling, the A4 Allroad’s wheelbase is 1.1 inches longer than on the RX (110.9 inches vs. 109.8 inches).

The A4 Allroad Prestige handles at .85 G’s, while the RX 350 F Sport AWD pulls only .82 G’s of cornering force in a Car and Driver skidpad test.

The A4 Allroad Premium Plus executes Motor Trend’s “Figure Eight” maneuver 1.2 seconds quicker than the RX 450h (26.3 seconds @ .69 average G’s vs. 27.5 seconds @ .65 average G’s).

The Audi A4 Allroad may be more efficient, handle and accelerate better because it weighs about 400 to 900 pounds less than the Lexus RX.

The A4 Allroad is 5 inches shorter than the RX, making the A4 Allroad easier to handle, maneuver and park in tight spaces.

The A4 Allroad is 8.9 inches shorter in height than the RX, making the A4 Allroad much easier to wash and garage and drive (lower center of gravity).

The A4 Allroad has a much larger cargo volume with its rear seat up than the RX with its rear seat up (24.2 vs. 16 cubic feet). The A4 Allroad has a much larger cargo volume with its rear seat folded than the RX with its rear seat folded (58.5 vs. 32.6 cubic feet).

The A4 Allroad’s standard towing capacity is much higher than the RX’s (3968 vs. 0 pounds).

The engine in the A4 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.

Heated windshield washer nozzles are standard on the A4 Allroad to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The RX doesn’t offer heated windshield washer nozzles.

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 A4 Allroad’s available headlights were rated “Good” 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 A4 Allroad Prestige has standard headlight washers to keep headlight output high. The RX doesn’t offer headlight washers.

The A4 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 A4 Allroad Prestige’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 doesn’t offer an automated parking system.
