Safety

The X7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Bentayga doesn’t offer pre-crash pretensioners.

The X7 has standard Post-Crash Braking, which automatically apply 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 X7’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 Bentayga doesn’t offer a driver alert monitor.

The X7 has standard BMW Assist, 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 Bentayga 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 X7 and the Bentayga have standard driver and passenger frontal airbags, side-impact head airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, blind spot warning systems, rearview cameras and available around view monitors.

Warranty

The X7 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 X7’s corrosion warranty is 9 years longer than the Bentayga’s (12 vs. 3 years).

BMW pays for scheduled maintenance on the X7 for 3 years and 36,000 miles. BMW will pay for oil changes, lubrication and any other required maintenance. Bentley doesn’t pay scheduled maintenance for the Bentayga.

There are almost 8 times as many BMW dealers as there are Bentley dealers, which makes it much easier should you ever need service under the X7’s warranty.

Fuel Economy and Range

Regenerative brakes improve the X7’s fuel efficiency by converting inertia back into energy instead of wasting it. The Bentayga doesn’t offer a regenerative braking system.

Environmental Friendliness

The U.S. Environmental Protection Agency (EPA) certifies the BMW X7 as an “Ultra Low Emissions Vehicle” (ULEV). The Bentley Bentayga is only certified to “Low Emissions Vehicle” (LEV) standards.

Transmission

The X7’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.

Tires and Wheels

For better traction and acceleration, the X7 has larger standard rear tires than the Bentayga (315/35R22 vs. 275/50R20).

The X7’s standard tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Bentayga’s standard 50 series tires. The X7’s optional 315/35R22 rear tires have a lower 35 series profile than the Bentayga’s optional 40 series tires.

For better ride, handling and brake cooling the X7 has standard 21-inch wheels. Smaller 20-inch wheels are standard on the Bentayga.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the X7 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Bentayga doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the X7’s wheelbase is 4.3 inches longer than on the Bentayga (122.2 inches vs. 117.9 inches).

Chassis

The front grille of the X7 uses electronically controlled shutters to close off airflow and reduce drag when less engine cooling is needed. This helps improve highway fuel economy. The Bentayga doesn’t offer active grille shutters.

Passenger Space

The X7 has 1.6 inches more front headroom and .7 inches more rear headroom than the Bentayga.

Cargo Capacity

The X7’s cargo area provides more volume than the Bentayga.

The X7’s rear cargo window opens separately from the rest of the tailgate door to allow quicker loading of small packages. The Bentayga’s rear cargo window doesn’t open.

Ergonomics

To improve rear visibility by keeping the rear window clear, the X7 has a standard rear variable intermittent wiper with a full on position. The rear wiper standard on the Bentayga only has an intermittent setting, so in a hard rain visibility isn’t as good.
