Safety

The Volvo S90 offers optional built in child booster seats. They’re more crash worthy than an added child seat because of their direct attachment to the seat. Audi doesn’t offer the convenience and security of a built-in child booster seat in the A6. Their owners must carry a heavy booster seat in and out of the vehicle; S90 owners can just fold their built-in child seat up or down.

The S90 has a standard Whiplash Protection System (WHIPS), which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the WHIPS moves the headrests forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The A6 doesn’t offer a whiplash protection system.

The S90’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 A6 doesn’t offer a driver alert monitor.

Both the S90 and the A6 have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, post-collision automatic braking systems, daytime running lights, rearview cameras, available all wheel drive and around view monitors.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the S90 the rating of “Top Pick” for 2017, a rating granted to only 154 vehicles tested by the IIHS. The A6 has not been tested, yet.

Warranty

Volvo pays for scheduled maintenance on the S90 for 3 years and 36,000 miles. Volvo will pay for oil changes, lubrication and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the A6.

Engine

The S90 T8’s standard 2.0 DOHC 4 cyl. hybrid produces 65 more horsepower (400 vs. 335) and 103 lbs.-ft. more torque (472 vs. 369) than the A6’s 3.0 turbo V6 hybrid.

The S90 T8 can drive on battery power alone for up to 21 miles. The A6 must run its internal combustion engine to move.

The S90 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

An eight-speed automatic is standard on the Volvo S90, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the A6.

Brakes and Stopping

For better stopping power the S90 T6/T8’s front brake rotors are larger than those on the A6:

Suspension and Handling

For a smoother ride and more stable handling, the S90’s wheelbase is 5.4 inches longer than on the A6 (120.5 inches vs. 115.1 inches).

Chassis

The Volvo S90 may be more efficient, handle and accelerate better because it weighs up to about 400 pounds less than the Audi A6.

Passenger Space

The S90 has .9 inches more front legroom and 3 inches more rear legroom than the A6.

Cargo Capacity

Pressing a switch automatically lowers the S90’s rear seats, to make changing between passengers and cargo easier. The A6 doesn’t offer automatic folding seats.

Towing

The S90’s standard towing capacity is much higher than the A6’s (3700 vs. 3500 pounds). Maximum trailer towing in the Audi A6 is only 3500 pounds. The S90 offers up to a 4600 lbs. towing capacity.

Ergonomics

The S90 has a standard 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.

Heated windshield washer nozzles are standard on the S90 to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The A6 doesn’t offer heated windshield washer nozzles.

The S90 Inscription has standard front air-conditioned seats and offers them optionally in the rear. This keeps the passengers comfortable and takes the sting out of hot seats in summer. The A6 doesn’t offer air-conditioned seats in the rear.

The S90 has a 115-volt a/c outlet on the center console, allowing you to recharge a laptop or run small household appliances without special adapters that can break or get misplaced. The A6 doesn’t offer a house-current electrical outlet.

The S90’s optional Park Assist Pilot can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The A6 doesn’t offer an automated parking system.

Model Availability

The S90 is available in both front-wheel drive and all-wheel drive configurations. The A6 doesn’t offer a two-wheel drive configuration.

Recommendations

The S90 was chosen as one of Automobile Magazine’s “All Stars” in 2017. The A6 has never been an “All Star.”
