The TLX has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them. A system to reveal vehicles in the A5 Sportback’s blind spot costs extra.

To help make backing out of a parking space safer, the TLX has standard Rear Cross Traffic Monitor, helping the driver avoid collisions. Audi charges extra for Rear Cross-Traffic Assist on the A5 Sportback.

The TLX’s driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The A5 Sportback doesn’t offer a driver alert monitor.

Both the TLX and the A5 Sportback 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 all wheel drive and around view monitors.

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 TLX its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 129 vehicles tested by the IIHS. The A5 Sportback is only a standard “Top Safety Pick” for 2022.

Warranty

Acura’s powertrain warranty covers the TLX 2 years and 20,000 miles longer than Audi covers the A5 Sportback. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the A5 Sportback ends after only 4 years or 50,000 miles.

Acura pays for scheduled maintenance on the TLX for 2 years and 24,000 miles. Acura will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the A5 Sportback.

Reliability

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Acura vehicles are better in initial quality than Audi vehicles. With 14 fewer problems per 100 vehicles, JD Power ranks Acura higher than Audi.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Acura vehicles are more reliable than Audi vehicles. Consumer Reports ranks Acura fourth in overall reliability. Audi is ranked 19th.

Engine

The TLX’s standard 2.0 turbo 4-cylinder produces 71 more horsepower (272 vs. 201) and 44 lbs.-ft. more torque (280 vs. 236) than the A5 Sportback 40 TFSI’s standard 2.0 turbo 4-cylinder hybrid. The TLX’s 2.0 turbo 4-cylinder produces 11 more horsepower (272 vs. 261) and 7 lbs.-ft. more torque (280 vs. 273) than the A5 Sportback 45 TFSI’s standard 2.0 turbo 4-cylinder hybrid. The TLX Type S’ standard 3.0 turbo V6 produces 94 more horsepower (355 vs. 261) and 81 lbs.-ft. more torque (354 vs. 273) than the A5 Sportback 45 TFSI’s standard 2.0 turbo 4-cylinder hybrid.

Fuel Economy and Range

An engine control system that can shut down some of the engine’s cylinders helps improve the TLX Type S’ fuel efficiency. The A5 Sportback doesn’t offer a system that can shut down part of the engine.

The TLX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The A5 Sportback doesn’t offer a cap-less fueling system.

Transmission

A 10-speed automatic is standard on the Acura TLX, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A5 Sportback.

Brakes and Stopping

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

	TLX	TLX Type S	A5 Sportback 40 TFSI	A5 Sportback 45 TFSI
Front Rotors	13 inches	14.3 inches	12.3 inches	13.3 inches
Rear Rotors	13 inches	13 inches	11.8 inches	13 inches

Tires and Wheels

For better traction, the TLX has larger tires than the A5 Sportback (255/35R20 vs. 245/40R18).

For better ride, handling and brake cooling the TLX has standard 19-inch wheels. Smaller 18-inch wheels are standard on the A5 Sportback. The TLX Type S’ 20-inch wheels are larger than the 19-inch wheels optional on the A5 Sportback.

The TLX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The A5 Sportback doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

For a smoother ride and more stable handling, the TLX’s wheelbase is 1.8 inches longer than on the A5 Sportback (113 inches vs. 111.2 inches).

For better handling and stability, the track (width between the wheels) on the TLX is 1.5 inches wider in the front and 2.9 inches wider in the rear than on the A5 Sportback.

The TLX Type S handles at .96 G’s, while the A5 Sportback Prestige pulls only .93 G’s of cornering force in a Car and Driver skidpad test.

Chassis

The TLX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The A5 Sportback doesn’t offer active noise cancellation.

Passenger Space

The TLX has 2.4 cubic feet more passenger volume than the A5 Sportback (93.4 vs. 91).

The TLX has 1.2 inches more front legroom, 2.5 inches more front shoulder room and .5 inches more rear shoulder room than the A5 Sportback.

Cargo Capacity

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the TLX offers cargo security. The A5 Sportback’s hatchback body style defeats cargo security.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Acura service is better than Audi. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 6% lower rating, Audi is ranked 8th.

Ergonomics

The TLX’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. The A5 Sportback doesn’t offer an easy entry system.

If the windows are left open on the TLX the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the A5 Sportback can’t use the remote to operate the windows.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Acura TLX has a standard wireless phone charging system (Qi) in the center console. Only the A5 Sportback Premium Plus/Prestige offers wireless charging.

Model Availability

The TLX is available in both front-wheel drive and all-wheel drive configurations. The A5 Sportback doesn’t offer a two-wheel drive configuration.

Economic Advantages

Insurance will cost less for the TLX owner. The Complete Car Cost Guide estimates that insurance for the TLX will cost $1230 to $7370 less than the A5 Sportback over a five-year period.

IntelliChoice estimates that five-year ownership costs (depreciation, financing, insurance, fuel, fees, repairs and maintenance) for the Acura TLX will be $834 to $7572 less than for the Audi A5 Sportback.

Recommendations

Consumer Reports® recommends the Acura TLX, based on reliability, safety and performance.

J.D. Power and Associates rated the TLX second among midsize premium cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The A5 Sportback isn’t in the top three in its category.
