Safety

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the A6. But it costs extra on the S90.

A passive infrared night vision system optional on the A6 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The S90 doesn’t offer a night vision system.

Both the A6 and the S90 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Audi vehicles are more reliable than Volvo vehicles. J.D. Power ranks Audi 13th in reliability, above the industry average. With 21 more problems per 100 vehicles, Volvo is ranked 22nd.

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Volvo vehicles. Consumer Reports ranks Audi 22 places higher in reliability than Volvo.

Engine

The A6’s 3.0 turbo V6 hybrid produces 85 more horsepower (335 vs. 250) and 111 lbs.-ft. more torque (369 vs. 258) than the S90 T5’s standard 2.0 turbo 4 cyl. The A6’s 3.0 turbo V6 hybrid produces 19 more horsepower (335 vs. 316) and 74 lbs.-ft. more torque (369 vs. 295) than the S90 T6’s standard 2.0 DOHC 4 cyl.

Fuel Economy and Range

To lower fuel costs and make buying fuel easier, the Audi A6 uses regular unleaded gasoline (premium recommended for maximum performance). The S90 T5 requires premium, which can cost 20 to 55 cents more per gallon.

The A6 has 6.1 gallons more fuel capacity than the S90 T8 Plug-In Hybrid’s standard fuel tank (19.3 vs. 13.2 gallons), for longer range between fill-ups. The A6 has 3.4 gallons more fuel capacity than the S90 T6’s standard fuel tank (19.3 vs. 15.9 gallons).

Transmission

The A6 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 S90 doesn’t offer an SMG or a conventional manual transmission.

Brakes and Stopping

For better stopping power the A6’s standard brake rotors are larger than those on the S90:

13.3 inches

12.7 inches

Rear Rotors

13 inches

11.9 inches

Tires and Wheels

For better ride, handling and brake cooling the A6 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the S90. The A6 Prestige’s optional 21-inch wheels are larger than the 20-inch wheels optional on the S90.

Suspension and Handling

For better handling and stability, the track (width between the wheels) on the A6 is 1.3 inches wider in the front than the average track on the S90.

For better maneuverability, the A6’s turning circle is 2.3 feet tighter than the S90 18” wheels’ (36.4 feet vs. 38.7 feet). The A6’s turning circle is 3.6 feet tighter than the S90 19” wheels’ (36.4 feet vs. 40 feet).

Chassis

The A6 is 5.7 inches shorter than the S90, making the A6 easier to handle, maneuver and park in tight spaces.

Passenger Space

The A6 has .2 inches more front headroom, .3 inches more front shoulder room, .3 inches more rear headroom and 1.1 inches more rear shoulder room than the S90.

Cargo Capacity

The A6’s standard rear seats fold to accommodate long and bulky cargo. The S90 Luxury Package doesn’t offer folding rear seats.

Servicing Ease

The engine in the A6 is mounted longitudinally (North-South), instead of sideways, as in the S90. This makes it easier to service and maintain, because the accessory belts are in front.

J.D. Power and Associates surveys of service recipients show that Audi service is better than Volvo. J.D. Power ranks Audi third in service department satisfaction. With a 29% lower rating, Volvo is ranked 14th.

Ergonomics

The A6’s standard easy entry system raises the steering wheel, making it easier for the driver to get in and out. The S90 doesn’t offer an easy entry system.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the A6 has standard extendable sun visors. The S90 doesn’t offer extendable visors.

Recommendations

The Audi A6/S6 outsold the Volvo 90 Series by 47% during 2017.
