Safety

Both the TLX and the A6 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, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in the IIHS moderate overlap frontal impact, side impact, rear impact, roof-crush crash tests, an “Acceptable” rating in the newer small overlap frontal crash test, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the TLX its highest rating: “Top Pick Plus” for 2015, a rating granted to only 159 vehicles tested by the IIHS. The A6 has not been tested, yet.

Warranty

Acura’s powertrain warranty covers the TLX 2 years and 20,000 miles longer than Audi covers the A6. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the A6 ends after only 4 years or 50,000 miles.

Reliability

J.D. Power and Associates’ 2018 Initial Quality Study of new car owners surveyed provide the statistics that show that Acura vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Acura 20th in initial quality. With 6 more problems per 100 vehicles, Audi is ranked 25th.

Fuel Economy and Range

An engine control system that can shut down half of the engine’s cylinders helps improve the TLX V6’s fuel efficiency. The A6 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 A6 doesn’t offer a cap-less fueling system.

Transmission

A nine-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 A6.

Tires and Wheels

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 A6 doesn’t offer vehicle monitored tire inflation.

Chassis

The Acura TLX may be more efficient, handle and accelerate better because it weighs about 450 to 750 pounds less than the Audi A6.

The TLX is 3.7 inches shorter than the A6, making the TLX easier to handle, maneuver and park in tight spaces.

The TLX uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The A6 doesn’t offer active noise cancellation.

Cargo Capacity

The TLX has a larger trunk than the A6 (14.3 vs. 13.7 cubic feet).

Ergonomics

The TLX offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The A6 doesn’t offer a remote starting system.

Model Availability

The TLX is available in both front-wheel drive and all-wheel drive configurations. The A6 doesn’t offer a two-wheel drive configuration.

Recommendations

The Car Book by Jack Gillis recommends the Acura TLX, based on economy, maintenance, safety and complaint levels.

The Acura TLX outsold the Audi A6/S6 by almost three to one during 2018.
