The A5 Sportback’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.

The A5 Sportback has a standard Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. The TLX doesn’t offer a whiplash protection system.

The A5 Sportback 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 A5 Sportback. But it costs extra on the TLX.

Both the A5 Sportback 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 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 35 MPH front crash tests on new vehicles. In this test, results indicate that the Audi A5 Sportback is safer than the Acura TLX:

	A5 Sportback	TLX
	Passenger
STARS	4 Stars	4 Stars
HIC	236	358
Neck Injury Risk	25%	32%
Neck Stress	119 lbs.	186 lbs.
Neck Compression	47 lbs.	66 lbs.
Leg Forces (l/r)	324/341 lbs.	416/473 lbs.

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

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 A5 Sportback is safer than the Acura TLX:

	A5 Sportback	TLX
	Into Pole
STARS	5 Stars	5 Stars
Max Damage Depth	12 inches	12 inches
HIC	333	464

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

Warranty

The A5 Sportback’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 A5 Sportback’s warranty.

Reliability

The Audi A5 Sportback’s engines use 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 A5 Sportback’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.

From surveys of all its subscribers, Consumer Reports’ January 2021 Auto Issue reports that Audi vehicles are more reliable than Acura vehicles. Consumer Reports ranks Audi 14 places higher in reliability than Acura.

Fuel Economy and Range

On the EPA test cycle the A5 Sportback gets better mileage than the TLX:

			MPG
A5 Sportback
	AWD	40 TFSI 2.0 turbo 4-cyl. Hybrid	24 city/33 hwy
		45 TFSI 2.0 turbo 4-cyl. Hybrid	24 city/32 hwy
TLX
	FWD	2.0 turbo 4-cyl.	22 city/31 hwy
		A-Spec 2.0 turbo 4-cyl.	22 city/30 hwy
	AWD	2.0 turbo 4-cyl.	21 city/29 hwy
		3.0 turbo V6	19 city/25 hwy
		Perf. Tire 3.0 turbo V6	19 city/24 hwy

Regenerative brakes improve the A5 Sportback’s fuel efficiency by converting inertia back into energy instead of wasting it. The TLX doesn’t offer a regenerative braking system.

Transmission

The A5 Sportback 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.

The A5 Sportback’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 TLX doesn’t offer launch control.

Brakes and Stopping

For better stopping power the A5 Sportback’s standard brake rotors are larger than those on the TLX:

	A5 Sportback	TLX
Front Rotors	13.3 inches	13 inches

The A5 Sportback’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.

The A5 Sportback stops much shorter than the TLX:

	A5 Sportback	TLX
70 to 0 MPH	159 feet	177 feet	Car and Driver

Tires and Wheels

For better traction, the A5 Sportback has larger standard tires than the TLX (245/40R18 vs. 235/50R18).

The A5 Sportback’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the TLX’s standard 50 series tires.

The A5 Sportback 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 TLX; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

The A5 Sportback’s front to rear weight distribution is more even (54.8% to 45.2%) than the TLX’s (57% to 43%). This gives the A5 Sportback more stable handling and braking.

The A5 Sportback Prestige handles at .94 G’s, while the TLX A-Spec SH-AWD pulls only .87 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the A5 Sportback’s turning circle is 1.7 feet tighter than the TLX’s (38.4 feet vs. 40.1 feet). The A5 Sportback’s turning circle is 1.8 feet tighter than the TLX Technology/A-Spec/Advance/Type S’ (38.4 feet vs. 40.2 feet).

Chassis

The A5 Sportback is 7.4 inches shorter than the TLX, making the A5 Sportback easier to handle, maneuver and park in tight spaces.

Passenger Space

Because it has more passenger and cargo room, the EPA rates the A5 Sportback a Mid-size car, while the TLX is rated a Compact.

The A5 Sportback has .5 inches more front headroom, .7 inches more rear headroom and .2 inches more rear legroom than the TLX.

Cargo Capacity

To make loading and unloading groceries and cargo easier, especially for short adults, the A5 Sportback has a standard power liftgate, 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.

Servicing Ease

The engine in the A5 Sportback is mounted longitudinally (North-South), instead of sideways, as in the TLX. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Ergonomics

The power windows standard on both the A5 Sportback and the TLX have locks to prevent small children from operating them. When the lock on the A5 Sportback 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 A5 Sportback’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 A5 Sportback 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 A5 Sportback Premium Plus/Prestige has standard headlight washers to keep headlight output high. The TLX doesn’t offer headlight washers.

The A5 Sportback’s standard rear view mirror and optional 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 A5 Sportback Prestige’s 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 TLX doesn’t offer an automated parking system.

Model Availability

The Audi A5 comes in coupe, convertible and four door hatchback bodystyles; the Acura TLX isn’t available as a coupe or convertible.

Recommendations

The Audi A5/S5 outsold the Acura TLX by 34% during the 2022 model year.
