Compare the2023 Audi RS Q8VS 2023 Bentley Bentayga

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.

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.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Acceptable” rating, the Insurance Institute for Highway Safety grants the RS Q8 its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 128 vehicles tested by the IIHS. The Bentayga has not been tested, yet.

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 23-inch wheels are larger than the 22-inch wheels optional on the Bentayga.

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 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 six to one during 2022.
