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 Macan doesn’t offer pre-crash pretensioners.
Both the Q8 and Macan 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 Macan’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.
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 Macan doesn’t offer a night vision system.
To help make backing safer, the Q8’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The Macan doesn’t offer a cross-path warning system.
The Q8 has a standard Audi Connect CARE, which uses a global positioning satellite (GPS) receiver and a cellular system to remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The Macan doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.
Both the Q8 and the Macan have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, post-collision automatic braking systems, rearview cameras, available lane departure warning systems, blind spot warning systems and around view monitors.
The Audi Q8 weighs 760 to 1102 pounds more than the Porsche Macan. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.
There are over 59 percent more Audi dealers than there are Porsche dealers, which makes it much easier should you ever need service under the Q8’s warranty.
From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Audi vehicles are more reliable than Porsche vehicles. Consumer Reports ranks Audi 4 places higher in reliability than Porsche.
The Q8’s 3.0 turbo V6 hybrid produces 83 more horsepower (335 vs. 252) and 96 lbs.-ft. more torque (369 vs. 273) than the Macan’s standard 2.0 turbo 4 cyl. The Q8’s 3.0 turbo V6 hybrid produces 30 lbs.-ft. more torque (369 vs. 339) than the Macan S’ standard 3.0 turbo V6.
To lower fuel costs and make buying fuel easier, the Audi Q8 uses regular unleaded gasoline (premium recommended for maximum performance). The Macan requires premium, which can cost 20 to 55 cents more per gallon.
The Q8 has 2.7 gallons more fuel capacity than the Macan (22.5 vs. 19.8 gallons), for longer range between fill-ups.
An eight-speed automatic is standard on the Audi Q8, for better acceleration and lower engine speed on the highway. Only a seven-speed automatic is available for the Macan.
For better stopping power the Q8’s standard brake rotors are larger than those on the Macan:
For better traction, the Q8 has larger standard tires than the Macan (275/50R20 vs. 235/55R19). The Q8’s optional tires are larger than the largest tires available on the Macan (285/45R21 vs. 265/40R21).
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 Macan’s standard 60 series front and 55 series rear tires.
For better ride, handling and brake cooling the Q8 has standard 20-inch wheels. Smaller 18-inch wheels are standard on the Macan. The Q8’s optional 22-inch wheels are larger than the 21-inch wheels optional on the Macan.
For a smoother ride and more stable handling, the Q8’s wheelbase is 7.4 inches longer than on the Macan (117.9 inches vs. 110.5 inches).
For better handling and stability, the track (width between the wheels) on the Q8 is .9 inches wider in the front and 1.8 inches wider in the rear than on the Macan.
The design of the Audi Q8 amounts to more than styling. The Q8 has an aerodynamic coefficient of drag of .35 Cd. That is lower than the Macan (.36 to .37). A more efficient exterior helps keep the interior quieter and helps the Q8 get better fuel mileage.
The Q8 has .8 inches more front legroom, 2.6 inches more front shoulder room, 4.6 inches more rear legroom and 3.6 inches more rear shoulder room than the Macan.
For enhanced passenger comfort on long trips the Q8’s rear seats recline. The Macan’s rear seats don’t recline.

To make loading groceries and cargo easier when your hands are full, the Q8 Premium Plus/Prestige’s liftgate can be opened and closed just by kicking your foot under the back bumper, leaving your hands completely free. The Macan doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.
The Q8’s standard towing capacity is much higher than the Macan’s (7700 vs. 4409 pounds).
The Q8 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 Macan doesn’t offer a remote starting system.
The Q8’s standard easy entry system raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Macan.
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 Macan doesn’t offer a heads-up display.
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 Macan can only operate the windows from inside the vehicle, with the ignition on.
To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Q8 has standard extendable sun visors. The Macan doesn’t offer extendable visors.
A manual rear sunshade is optional in the Q8 to help block heat and glare for the rear passengers. The Macan doesn’t offer a rear sunshade.
