Compare the2025 Audi Q3VS 2025 Lexus NX

The Q3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The NX doesn’t offer pre-crash pretensioners.

Both the Q3 and NX have child safety locks to prevent children from opening the rear doors. The Q3 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 NX’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 Audi Q3 has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The NX doesn’t offer a front passenger side knee airbag.

The Q3 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 NX 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 Q3. But it costs extra on the NX.

Both the Q3 and the NX have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front 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, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The Q3’s corrosion warranty is 6 years longer than the NX’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 Q3’s warranty.

The Audi Q3’s engines use a cast iron block for durability, while the NX’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

J.D. Power and Associates rated the Q3 second among small premium suvs in their 2024 Initial Quality Study. The NX isn’t in the top three in its category.

On the EPA test cycle the Q3 40 TFSI gets better fuel mileage than the NX 350 running its gasoline engine (22 city/29 hwy vs. 21 city/28 hwy).

Both the Q3 and the NX have a standard automatic start/stop engine feature to stop unnecessary fuel waste and pollution at stoplights and heavy traffic. All Q3s have a standard disable switch for the system, so a driver can keep the engine from shutting off when the vehicle stops temporarily. The NX 350h/450h+ doesn’t offer a way to disable start/stop.

To lower fuel costs and make buying fuel easier, the Audi Q3 uses regular unleaded gasoline (premium recommended for maximum performance). The NX 350 AWD requires premium, which can cost on average about 84.9 cents more per gallon.

The Q3 has 1.4 gallons more fuel capacity than the NX (15.9 vs. 14.5 gallons), for longer range between fill-ups.

For better stopping power the Q3’s front brake rotors are larger than those on the NX:

The Q3 stops much shorter than the NX:

For better traction, the Q3’s optional tires are larger than the largest tires available on the NX (255/45R19 vs. 235/60R18).

The Q3’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the NX’s standard 60 series tires. The Q3’s optional tires have a lower 40 series profile than the NX’s optional 50 series tires.

The Q3 has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the NX; it requires you to depend on its run-flat tires, which limits mileage and speed before they are repaired. If a run-flat is damaged beyond repair by a road hazard your vehicle will have to be towed.

The Q3 handles at .91 G’s, while the NX 350 AWD pulls only .81 G’s of cornering force in a Car and Driver skidpad test.

The Q3 is 6.9 inches shorter than the NX, making the Q3 easier to handle, maneuver and park in tight spaces.

The Q3 has 1.3 inches more front headroom, .4 inches more front shoulder room and 1.1 inches more rear shoulder room than the NX.

The Q3 has a larger cargo volume with its rear seat up than the NX with its rear seat up (23.7 vs. 22.7 cubic feet). The Q3 has a larger cargo volume with its rear seat folded than the NX with its rear seat folded (48 vs. 46.9 cubic feet).

A low lift-over cargo hatch design makes loading and unloading the Q3 easier. The Q3’s cargo hatch lift-over height is 27.8 inches, while the NX’s liftover is 30.8 inches.

The Q3’s standard towing capacity is much higher than the NX’s (1500 vs. 0 pounds).

The power windows standard on both the Q3 and the NX have locks to prevent small children from operating them. When the lock on the Q3 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The NX prevents the driver from operating the other windows just as it does the other passengers.

If the windows are left open on the Q3 the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the NX can only close the windows from inside the vehicle, with the ignition on.

Heated windshield washer nozzles are standard on the Q3 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The NX doesn’t offer heated windshield washer nozzles.

Insurance will cost less for the Q3 owner. The Complete Car Cost Guide estimates that insurance for the Q3 will cost $140 less than the NX over a five-year period.
