The Q8 e-tron’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Solterra doesn’t offer pre-crash pretensioners.

Both the Q8 e-tron and Solterra have child safety locks to prevent children from opening the rear doors. The Q8 e-tron has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Solterra’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

Earlier warning of stopped traffic, traffic signals, dangerous road conditions, weather, or accidents, can keep driver's safer and prevent crashes. The Q8 e-tron has Car-to-X Services, a system that seemlesly communicates important warnings to the driver about impending danger, if they're available. The Solterra doesn’t offer a system that can receive automated systems from infrastructure.

Both the Q8 e-tron and the Solterra have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, post-collision automatic braking systems, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning and available around view monitors.

The Audi Q8 e-tron weighs 1312 to 1720 pounds more than the Subaru Solterra. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

Warranty

The Q8 e-tron comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Solterra’s 3-year/36,000-mile basic warranty expires 1 year or 14,000 miles sooner.

The Q8 e-tron’s corrosion warranty is 7 years longer than the Solterra’s (12 vs. 5 years).

Engine

The Q8 e-tron’s standard electric motors produces 187 more horsepower (402 vs. 215) and 241 lbs.-ft. more torque (490 vs. 249) than the Solterra’s electric motors. The SQ8 e-tron’s standard electric motors produces 281 more horsepower (496 vs. 215) and 468 lbs.-ft. more torque (717 vs. 249) than the Solterra’s electric motors.

As tested in Consumer Reports the Audi Q8 e-tron (base engine) is faster than the Subaru Solterra:

	Q8 e-tron	Solterra
Zero to 60 MPH	6.3 sec	6.4 sec
45 to 65 MPH Passing	3.1 sec	3.6 sec
Quarter Mile	14.8 sec	15 sec
Speed in 1/4 Mile	99 MPH	93 MPH

Fuel Economy and Range

The Q8 e-tron can travel longer on a full charge than the Solterra on a full charge:

			Miles
Q8 e-tron
	AWD	Electric Motors	285 miles
		SQ8 20" Wheels Electric Motors	253 miles
Solterra
	AWD	Premium Electric Motors	227 miles
		Limited/Touring Electric Motors	222 miles

The Q8 e-tron has a standard locking charge port which locks and unlocks with the power locks. The Solterra doesn’t have a locking charge port. A locking charge port prevents tampering and damage.

Transmission

The Q8 e-tron’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 Solterra doesn’t offer launch control.

Brakes and Stopping

For better stopping power the Q8 e-tron’s brake rotors are larger than those on the Solterra:

	Q8 e-tron	Solterra
Front Rotors	15.7 inches	12.9 inches
Rear Rotors	13.8 inches	12.5 inches

The Q8 e-tron stops shorter than the Solterra:

	Q8 e-tron	Solterra
60 to 0 MPH	131 feet	135 feet	Consumer Reports
60 to 0 MPH (Wet)	134 feet	145 feet	Consumer Reports

Tires and Wheels

For better traction, the Q8 e-tron has larger standard tires than the Solterra (255/50R20 vs. 235/60R18). The Q8 e-tron’s optional tires are larger than the largest tires available on the Solterra (265/45R21 vs. 235/60R18).

The Q8 e-tron’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Solterra Premium’s standard 60 series tires. The Q8 e-tron’s optional tires have a lower 45 series profile than the Solterra Limited/Touring’s 50 series tires.

For better ride, handling and brake cooling the Q8 e-tron has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Solterra Premium. The Q8 e-tron’s optional 21-inch wheels are larger than the 20-inch wheels on the Solterra Limited/Touring.

The Q8 e-tron 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 Solterra; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Suspension and Handling

The front and rear suspension of the Q8 e-tron uses air springs for a smoother, controlled ride than the Solterra, which uses coil springs. Air springs maintain proper ride height and ride more smoothly.

The Q8 e-tron has a standard driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads or off-road. The Solterra’s suspension doesn’t offer adjustable shock absorbers.

The Q8 e-tron has a standard automatic front and rear load leveling suspension to keep ride height level with a heavy load or when towing. The Q8 e-tron’s height leveling suspension allows the driver to raise ride height for better off-road clearance and then lower it again for easier entering and exiting and better on-road handling. The Solterra doesn’t offer a load leveling suspension.

For a smoother ride and more stable handling, the Q8 e-tron’s wheelbase is 2.9 inches longer than on the Solterra (115.1 inches vs. 112.2 inches).

For better handling and stability, the average track (width between the wheels) on the Q8 e-tron is 2.3 inches wider in the front and 1.8 inches wider in the rear than the track on the Solterra.

Passenger Space

The Q8 e-tron has 7.3 cubic feet more passenger volume than the Solterra (103 vs. 95.7).

The Q8 e-tron has .8 inches more front shoulder room, .6 inches more rear headroom, 3.8 inches more rear legroom and 1.3 inches more rear shoulder room than the Solterra.

Cargo Capacity

The Q8 e-tron has a much larger cargo volume than the Solterra with its rear seat up (28.5 vs. 23.8 cubic feet).

Pulling a handle automatically lowers the Q8 e-tron’s rear seats, to make changing between passengers and cargo easier. The Solterra doesn’t offer automatic folding seats.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Q8 e-tron. The Solterra doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the Q8 e-tron’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Solterra doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

Towing

The Q8 e-tron offers up to a 4000 lbs. towing capacity. The Solterra has no towing capacity.

Servicing Ease

The Q8 e-tron uses gas struts to support the hood for easier service access. The Solterra uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

J.D. Power and Associates surveys of service recipients show that Audi service is better than Subaru. J.D. Power ranks Audi 8th in service department satisfaction (above the industry average). With a 13% lower rating, Subaru is ranked 16th.

Ergonomics

Unlike the driver-only memory seat and mirrors in the Solterra Limited/Touring, the Q8 e-tron Prestige has a passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The Q8 e-tron Prestige has a standard heads-up display that projects speed in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Solterra doesn’t offer a heads-up display.

The Q8 e-tron’s standard Audi Advanced Key allows you to unlock the doors from any outside door handle, open the cargo door, and start the vehicle, all without removing the key from the pocket or purse. Keyless Access and Start standard on the Solterra doesn’t offer a sensor on the rear doors, so you’ll have to reach a front handle to unlock the rear door. Keyless Access and Start is not available on the Solterra Touring.

The Q8 e-tron’s power window, power lock and power mirror switches are lit from behind, making them plainly visible and easier to operate at night. The Solterra’s power window (except driver window) and power lock switches are unlit, making them difficult to find at night and operate safely.

The Q8 e-tron’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 Solterra Premium’s standard manually variable intermittent wipers have to be constantly adjusted.

To improve rear visibility by keeping the rear window clear, the Q8 e-tron has a standard rear wiper. The Solterra doesn’t offer a rear wiper.

Manual rear side window sunshades are available in the Q8 e-tron to help block heat and glare for the rear passengers. The Solterra doesn’t offer rear side window sunshades.

The Q8 e-tron’s standard rear and 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 Solterra offers an automatic rear view mirror, but its side mirrors don’t dim.

The Q8 e-tron has a standard heated steering wheel to take the chill out of steering on extremely cold winter days before the vehicle heater warms up. A heated steering wheel is only available on the Solterra Limited/Touring.

The Q8 e-tron Prestige/Launch Edition has standard massaging front seats in order to maximize comfort and eliminate fatigue on long trips. Massaging seats aren’t available in the Solterra.
