Compare the2025 Audi RS Q8VS 2025 Bentley Bentayga

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Audi RS Q8 achieved a “Acceptable” rating - the second highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Bentley Bentayga has not been tested.

The RS 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 Bentayga 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.

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

The RS Q8’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Bentayga.

Both the RS Q8 and the Bentayga have standard driver and passenger frontal airbags, front and rear 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, crash mitigating brakes, daytime running lights, blind spot warning systems, around view monitors, rear cross-path warning and available night vision systems.

The RS Q8 comes with a full 4-year/50,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The Bentayga’s 3-year basic warranty expires 1 year sooner.

The RS Q8’s corrosion warranty is 9 years longer than the Bentayga’s (12 vs. 3 years).

There are over 6 times as many Audi dealers as there are Bentley dealers, which makes it much easier should you ever need service under the RS Q8’s warranty.

The RS Q8’s 4.0 turbo V8 produces 175 more horsepower (631 vs. 456) and 111 lbs.-ft. more torque (627 vs. 516) than the Bentayga Hybrid’s standard 3.0 turbo V6 hybrid. The RS Q8’s 4.0 turbo V8 produces 89 more horsepower (631 vs. 542) and 59 lbs.-ft. more torque (627 vs. 568) than the Bentayga’s standard 4.0 turbo V8.

The RS Q8 has 2.7 gallons more fuel capacity than the Bentayga Hybrid’s standard fuel tank (22.5 vs. 19.8 gallons), for longer range between fill-ups.

The RS Q8’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 Bentayga doesn’t offer launch control.

For better stopping power the RS Q8’s front brake rotors are larger than those on the Bentayga:

For better traction, the RS Q8 has larger tires than the Bentayga (295/40R22 vs. 285/45R21).

The RS Q8’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Bentayga’s standard 45 series tires. The RS Q8’s optional tires have a lower 35 series profile than the Bentayga’s optional 40 series tires.

For better ride, handling and brake cooling the RS Q8 has standard 22-inch wheels. Smaller 21-inch wheels are standard on the Bentayga. The RS Q8’s optional 23-inch wheels are larger than the 22-inch wheels optional on the Bentayga.

The RS Q8 handles at .98 G’s, while the Bentayga pulls only .78 G’s of cornering force in a Car and Driver skidpad test.

The RS Q8 is 4.5 inches shorter than the Bentayga, making the RS Q8 easier to handle, maneuver and park in tight spaces.

The RS Q8 has a much larger cargo volume than the Bentayga with its rear seat up (30.5 vs. 17.1 cubic feet).

The RS Q8’s standard rear seats fold to accommodate long and bulky cargo. The Bentayga w/Four Seat Comfort Specification doesn’t offer folding rear seats, only a ski pass-through.

The RS Q8’s standard towing capacity is much higher than the Bentayga’s (7700 vs. 7165 pounds).

If the windows are left open on the RS Q8 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 Bentayga can only operate the windows from inside the vehicle, with the ignition on.

The RS Q8’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Bentayga’s cruise control switches are unlit, making them difficult to find at night and operate safely.

A manual rear sunshade is standard in the RS Q8 and power rear side window sunshades are optional to help block heat and glare for the rear passengers. The Bentayga doesn’t offer a rear sunshade.

The Audi RS Q8 has a standard Homelink wireless remote control system for garage door operation and device management, conveniently located on the overhead console. Homelink® eliminates the need for separate garage door openers and associated risks of losing, breaking, or having dead batteries. Bentley charges extra for Homelink® on the Bentayga.

The RS Q8’s optional Park Assist Plus can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. Remote Park Assist Plus will park and retrieve your car remotely: press a button and watch it park itself. This is ideal for tight locations. The Bentayga’s automatic parking system requires operating the brakes and transmission to safely park and it doesn’t offer remote control parking.

The Audi Q8/SQ8/RS Q8 outsold the Bentley Bentayga by over 8 to one during 2024.
