Compare the2024 BMW XMVS 2024 Audi RS Q8

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the XM are reminded to check the back seat if they opened the rear door before starting out. The RS Q8 doesn’t offer a back seat reminder.

The BMW XM has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The RS Q8 doesn’t offer knee airbags.

The XM’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 RS Q8 doesn’t offer a driver alert monitor.

Both the XM and the RS Q8 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, all wheel drive, 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, around view monitors and rear cross-path warning.

The BMW XM weighs 582 pounds more than the Audi RS Q8. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

BMW pays for scheduled maintenance on the XM for 3 years and 36,000 miles. BMW will pay for oil changes, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the RS Q8.

For better traction and acceleration, the XM has larger rear tires than the RS Q8 (315/30R23 vs. 295/40R22).

The XM’s standard 315/35R22 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the RS Q8’s standard 40 series tires. The XM’s optional 315/30R23 rear tires have a lower 30 series profile than the RS Q8’s 35 series tires.

The XM has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the RS Q8; it requires you to depend on roadside assistance and your vehicle will have to be towed.

J.D. Power and Associates surveys of service recipients show that BMW service is better than Audi. J.D. Power ranks BMW 7th in service department satisfaction (above the industry average). With a 1% lower rating, Audi is ranked 8th.

Unlike the driver-only memory system in the RS Q8, the XM has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position, outside mirror angle, climate settings and radio stations and the front passenger seat also adjusts to the new passenger’s preset preferences.

The RS Q8’s cornering lamps activate a lamp on the front corner when the turn signal is activated. The XM’s standard adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.
