Compare the2024 Audi S3VS 2024 Acura TLX

The S3’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The TLX doesn’t offer pre-crash pretensioners.

Both the S3 and TLX have child safety locks to prevent children from opening the rear doors. The S3 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 TLX’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 S3 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 TLX 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 S3. But it costs extra on the TLX.

Both the S3 and TLX offer rear cross-traffic warning, but the S3 with Rear Cross-Traffic Assist also has Automatic Brake Activation (automatically applies the brakes) to better prevent a collision when backing near traffic. The TLX’s Rear Cross Traffic Monitor doesn’t automatically brake.

Both the S3 and the TLX have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger 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, rearview cameras and available blind spot warning systems.

The S3’s corrosion warranty is 7 years longer than the TLX’s (12 vs. 5 years).

There are over 12 percent more Audi dealers than there are Acura dealers, which makes it easier should you ever need service under the S3’s warranty.

The Audi S3’s engine uses a cast iron block for durability, while the TLX’s engines use an aluminum block. Aluminum engine blocks are much more prone to warp and crack at high temperatures than cast iron.

A hardened steel chain, with no maintenance needs, drives the camshafts in the S3’s engine. A rubber cam drive belt that needs periodic replacement drives the TLX’s camshafts. If the TLX’s belt breaks, the engine could be severely damaged when the pistons hit the opened valves.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Acura With 12 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Audi higher than Acura.

The S3’s 2.0 turbo 4-cylinder produces 34 more horsepower (306 vs. 272) and 15 lbs.-ft. more torque (295 vs. 280) than the TLX’s standard 2.0 turbo 4-cylinder.

On the EPA test cycle the S3 gets better mileage than the TLX:

The S3 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 TLX doesn’t offer an SMG or a conventional manual transmission.

For better stopping power the S3’s standard front brake rotors are larger than those on the TLX:

The S3’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the TLX are solid, not vented.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the S3 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The TLX doesn’t offer run-flat tires.

For better maneuverability, the S3’s turning circle is 3.8 feet tighter than the TLX’s (36.4 feet vs. 40.2 feet).

The Audi S3 may be more efficient, handle and accelerate better because it weighs about 200 to 700 pounds less than the Acura TLX.

The S3 is 1 foot, 5.3 inches shorter than the TLX, making the S3 easier to handle, maneuver and park in tight spaces.

The S3 has .3 inches more rear headroom and .3 inches more rear legroom than the TLX.

To make loading and unloading groceries and cargo easier, especially for short adults, the S3 has a standard power trunk, which opens and closes automatically by pressing a button, or optionally by just kicking your foot under the back bumper, completely leaving your hands free. The TLX doesn’t offer a power trunk.

The S3 has a 3500 lbs. towing capacity. The TLX has no towing capacity.

The power windows standard on both the S3 and the TLX have locks to prevent small children from operating them. When the lock on the S3 is engaged the driver can still operate all of the windows, for instance to close one opened by a child. The TLX prevents the driver from operating the other windows just as it does the other passengers.

The S3’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The TLX’s standard intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

Heated windshield washer nozzles are standard on the S3 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The TLX doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The S3 Prestige has standard headlight washers to keep headlight output high. The TLX doesn’t offer headlight washers.

To help drivers avoid possible obstacles, the S3 has standard cornering lights to illuminate around corners when the turn signals are activated. The TLX doesn’t offer cornering lights.

The S3’s optional rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The TLX has an automatic rear view mirror, but its side mirrors don’t dim.

The S3’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 TLX doesn’t offer an automated parking system.

The S3 will cost the buyer less in the long run because of its superior resale value. The IntelliChoice estimates that the S3 will retain 53.69% to 55.79% of its original price after five years, while the TLX only retains 45.75% to 49.71%.
