For enhanced safety, the front and rear seat shoulder belts of the Audi Q8 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Chevrolet Blazer doesn’t offer pretensioners for the rear seat belts.
The Q8’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Blazer doesn’t offer pre-crash pretensioners.
Both the Q8 and Blazer have child safety locks to prevent children from opening the rear doors. The Q8 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 Blazer’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.
The Q8 has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Blazer doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.
To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q8. But it costs extra on the Blazer.
A passive infrared night vision system optional on the Q8 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 Blazer doesn’t offer a night vision system.
Both the Q8 and the Blazer have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.
The Audi Q8 weighs 717 to 1222 pounds more than the Chevrolet Blazer. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
The Q8 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Blazer’s 3-year/36,000-mile basic warranty expires 1 year and 14,000 miles sooner.
The Q8’s corrosion warranty is 6 years and unlimited miles longer than the Blazer’s (12/unlimited vs. 6/100,000).
From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Chevrolet vehicles. Consumer Reports ranks Audi 16 places higher in reliability than Chevrolet.
The Q8’s 3.0 turbo V6 hybrid produces 142 more horsepower (335 vs. 193) and 181 lbs.-ft. more torque (369 vs. 188) than the Blazer’s standard 2.5 DOHC 4 cyl. The Q8’s 3.0 turbo V6 hybrid produces 30 more horsepower (335 vs. 305) and 100 lbs.-ft. more torque (369 vs. 269) than the Blazer’s optional 3.6 DOHC V6.
Regenerative brakes improve the Q8’s fuel efficiency by converting inertia back into energy instead of wasting it. The Blazer doesn’t offer a regenerative braking system.
The Q8 has 3.1 gallons more fuel capacity than the Blazer FWD’s standard fuel tank (22.5 vs. 19.4 gallons), for longer range between fill-ups.
The Q8’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the Blazer are solid, not vented.
For better traction, the Q8 has larger standard tires than the Blazer (275/50R20 vs. 235/65R18). The Q8’s optional tires are larger than the largest tires available on the Blazer (285/45R21 vs. 265/45R21).
The Q8’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 Blazer’s standard 65 series tires. The Q8’s optional tires have a lower 40 series profile than the Blazer RS/Premier’s optional 45 series tires.
For better ride, handling and brake cooling the Q8 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Blazer. The Q8’s optional 22-inch wheels are larger than the 21-inch wheels optional on the Blazer RS/Premier.
The Q8 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 Blazer’s suspension doesn’t offer adjustable shock absorbers.
For a smoother ride and more stable handling, the Q8’s wheelbase is 5.2 inches longer than on the Blazer (117.9 inches vs. 112.7 inches).
The Q8 has .7 inches more front legroom, .4 inches more front shoulder room and .6 inches more rear legroom than the Blazer.
For enhanced passenger comfort on long trips the Q8’s rear seats recline. The Blazer’s rear seats don’t recline.
The Q8 has a larger cargo volume with its rear seat folded than the Blazer with its rear seat folded (67.5 vs. 64.2 cubic feet).
The Q8’s standard towing capacity is much higher than the Blazer’s (7700 vs. 1500 pounds).
The engine in the Q8 is mounted longitudinally (North-South), instead of sideways, as in the Blazer. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.
J.D. Power and Associates surveys of service recipients show that Audi service is better than Chevrolet. J.D. Power ranks Audi third in service department satisfaction. With a 22% lower rating, Chevrolet is ranked 10th.
Unlike the driver-only memory system optional at extra cost in the Blazer (except L/LT), the Q8 offers an optional 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 Prestige has a standard heads-up display that projects speed readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Blazer doesn’t offer a heads-up display.
The Q8’s front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Blazer’s passenger windows don’t close automatically.
If the windows are left open on the Q8 Premium Plus/Prestige the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows from a distance using the keyless remote. The driver of the Blazer can only close the windows from inside the vehicle, with the ignition on.
The Q8’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 Blazer’s manually variable intermittent wipers have to be constantly adjusted.
In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The Q8 Prestige has standard headlight washers to keep headlight output high. The Blazer doesn’t offer headlight washers.
When the Q8 is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Blazer’s mirror doesn’t automatically adjust for backing.
