Safety

The Q7’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Cullinan doesn’t offer pre-crash pretensioners.

The Q7 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 Cullinan 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 Q7 offers an optional backup collision prevention system that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Cullinan doesn’t offer backup collision prevention brakes.

Both the Q7 and the Cullinan have standard driver and passenger frontal airbags, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, available night vision systems, lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Q7 the rating of “Top Pick” for 2017, a rating granted to only 157 vehicles tested by the IIHS. The Cullinan has not been tested, yet.

Warranty

The Q7’s corrosion warranty is 8 years longer than the Cullinan’s (12 vs. 4 years).

There are over 8 times as many Audi dealers as there are Rolls-Royce dealers, which makes it much easier should you ever need service under the Q7’s warranty.

Fuel Economy and Range

On the EPA test cycle the Q7 gets better fuel mileage than the Cullinan:

In heavy traffic or at stoplights the Q7’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Cullinan doesn’t offer an automatic engine start/stop system.

Transmission

For more complete vehicle control the Q7 has a manually controlled automatic, with the available convenience of an automatic transmission and the complete gear control of a manual transmission without the inconvenience of a clutch. A manually controlled automatic allows the driver to eliminate unwanted shifts and maximize engine braking by down shifting while cornering. The Cullinan doesn’t offer a transmission that allows complete gear control.

Tires and Wheels

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Q7 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The Cullinan doesn’t offer run-flat tires.

Suspension and Handling

For better maneuverability, the Q7’s turning circle is 2.7 feet tighter than the Cullinan’s (40.7 feet vs. 43.4 feet).

Chassis

The Audi Q7 may be more efficient, handle and accelerate better because it weighs about 950 to 1350 pounds less than the Rolls-Royce Cullinan.

The Q7 is 10.7 inches shorter than the Cullinan, making the Q7 easier to handle, maneuver and park in tight spaces.

For excellent aerodynamics, the Q7 has standard flush composite headlights. The Cullinan has recessed headlights that spoil its aerodynamic shape and create extra drag.

Passenger Space

The Q7 has standard seating for 7 passengers; the Cullinan can only carry up to 5.

Cargo Capacity

The Q7’s cargo area provides more volume than the Cullinan.

Q7

Cullinan

Second Seat Folded

71.6 cubic feet

68.2 cubic feet

The Q7’s standard rear seats fold to accommodate long and bulky cargo. The Cullinan w/Executive Rear Seats doesn’t offer folding rear seats.

The Q7’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The Cullinan’s tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.

Ergonomics

The Q7 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The Cullinan doesn’t offer a remote starting system.

To keep a safe, consistent following distance, the Q7 (except Premium) offers an optional Adaptive Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Cullinan doesn’t offer an adaptive cruise control.

Recommendations

Consumer Reports® recommends the Audi Q7, based on reliability, safety and performance.

The Q7 was chosen as one of Car and Driver’s “Top Five/10Best Trucks” for 3 of the last 3 years. The Cullinan has never been a Car and Driver “Top Five/10Best Truck” pick.
