Compare the2025 Porsche TaycanVS 2025 Audi Q8 e-tron

Over 200 people are killed each year when backed over by motor vehicles. The Taycan has a standard Maneuvering Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Q8 e-tron doesn’t offer automatic braking for stationary objects directly to the rear.

A passive infrared night vision system optional on the Taycan 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 Q8 e-tron doesn’t offer a night vision system.

The Taycan’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 Q8 e-tron doesn’t offer a driver alert monitor.

Both the Taycan and the Q8 e-tron 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, 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.

Porsche pays for scheduled maintenance on the Taycan for 2 years and 24,000 miles. Porsche will pay for cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the Q8 e-tron.

J.D. Power and Associates rated the Taycan first among upper midsize premium cars in their 2024 Initial Quality Study. The Q8 e-tron isn’t in the top three in its category.

J.D. Power and Associates’ 2024 Initial Quality Study of new car owners surveyed provide the statistics that show that Porsche vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Porsche above average in initial quality. With 70 more problems per 100 vehicles, Audi is rated below average.

J.D. Power and Associates’ 2024 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Porsche vehicles are more reliable than Audi vehicles. J.D. Power ranks Porsche above average in long-term dependability. With 15 more problems per 100 vehicles in the first three years of ownership, Audi is rated below average.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Porsche vehicles are more reliable than Audi vehicles. Consumer Reports ranks Porsche 11 places higher in reliability than Audi.

The Taycan has more powerful engines than the Q8 e-tron:

The Taycan Cross Turismo can travel longer on a full charge than the Q8 e-tron on a full charge:

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

The Taycan offers optional heat-treated ceramic brake rotors, which last ten to twenty times as long as conventional cast iron rotors, don’t rust, don’t fade during repeated high speed braking, and their lighter weight contribute to better braking, handling and acceleration. The Q8 e-tron doesn’t offer ceramic brake rotors.

The Taycan stops much shorter than the Q8 e-tron:

For better traction and acceleration, the Taycan has larger standard rear tires than the Q8 e-tron (275/45R19 vs. 255/50R20). The Taycan’s optional rear tires are larger than the largest rear tires available on the Q8 e-tron (305/30R21 vs. 265/45R21).

The Taycan’s standard 275/45R19 rear tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Q8 e-tron’s standard 50 series tires. The Taycan’s optional 265/35R21 front and 305/30R21 rear tires have a lower 35 series front and 30 series rear profile than the Q8 e-tron’s optional 45 series tires.

The Taycan AWD offers active sway bars, which help keep it flat and controlled during cornering, but disconnect at lower speeds to smooth the ride and offer greater off-road suspension articulation. This helps keep the tires glued to the road on-road and off. The Q8 e-tron doesn’t offer an active sway bar system.

The Taycan offers an available adjustable active suspension system, which counteracts cornering forces actively, limiting body roll and improving handling and stability. Audi doesn’t offer an active suspension on the Q8 e-tron.

For better handling and stability, the average track (width between the wheels) on the Taycan is 1.8 inches wider in the front and .9 inches wider in the rear than the average track on the Q8 e-tron.

The Taycan 4S Cross Turismo handles at .88 G’s, while the Q8 e-tron pulls only .85 G’s of cornering force in a Car and Driver skidpad test.

The Taycan 4 Cross Turisimo executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the Q8 e-tron (25 seconds @ .76 average G’s vs. 26.6 seconds @ .71 average G’s).

For better maneuverability, the Taycan w/Rear Axle Steering’s turning circle is 3.3 feet tighter than the Q8 e-tron’s (36.7 feet vs. 40 feet). The Taycan Cross Turismo’s turning circle is .6 feet tighter than the Q8 e-tron’s (39.4 feet vs. 40 feet).

The Porsche Taycan may be more efficient, handle and accelerate better because it weighs about 900 to 1150 pounds less than the Audi Q8 e-tron.

The Taycan is 11.1 inches shorter in height than the Q8 e-tron, making the Taycan much easier to wash and garage and drive (lower center of gravity).

The design of the Porsche Taycan amounts to more than styling. The Taycan offers aerodynamic coefficients of drag from .23 to .28 Cd (depending on bodystyle and options). That is lower than the Q8 e-tron (.29 to .32) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the Taycan get better fuel mileage.

J.D. Power and Associates surveys of service recipients show that Porsche service is better than Audi. J.D. Power ranks Porsche second in service department satisfaction. With a 40% lower rating, Audi is ranked 18th.

To improve rear visibility by keeping the rear window clear, the Taycan has a standard rear variable intermittent wiper with a full on position. The rear wiper standard on the Q8 e-tron only has an intermittent setting, so in a hard rain visibility isn’t as good.

To help drivers avoid possible obstacles, the Taycan offers optional cornering lights to illuminate around corners when the turn signals are activated. The Q8 e-tron doesn’t offer cornering lights. The Taycan also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Porsche Taycan has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Q8 e-tron.

The Porsche Taycan comes in sedan and station wagon bodystyles; the Audi Q8 e-tron isn’t available as a sedan.

The Taycan is available in both rear-wheel drive and all-wheel drive configurations. The Q8 e-tron doesn’t offer a two-wheel drive configuration.
