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 RXL doesn’t offer pre-crash pretensioners.

Both the Q7 and RXL have child safety locks to prevent children from opening the rear doors. The Q7 has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The RXL’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

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 RXL 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.

To provide maximum traction and stability on all roads, All-Wheel Drive is standard on the Q7. But it costs extra on the RXL.

A passive infrared night vision system optional on the Q7 Prestige helps the driver to more easily detect people, animals or other objects in front of the vehicle at night. Using an infrared camera to detect heat, the system then displays the image on a monitor in the dashboard. The RXL doesn’t offer a night vision system.

Both the Q7 and the RXL have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front and rear seatbelt pretensioners, height-adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems, around view monitors and rear cross-path warning.

Warranty

The Q7’s corrosion warranty is 6 years longer than the RXL’s (12 vs. 6 years).

There are over 26 percent more Audi dealers than there are Lexus dealers, which makes it easier should you ever need service under the Q7’s warranty.

Engine

The Q7 45 TFSI’s standard 2.0 turbo 4 cyl. produces 10 lbs.-ft. more torque (273 vs. 263) than the RX 350L’s standard 3.5 DOHC V6. The Q7 55 TFSI’s standard 3.0 supercharged V6 produces 21 more horsepower (329 vs. 308) than the RX 450hL’s standard 3.5 DOHC V6 hybrid.

As tested in Motor Trend the Q7 55 TFSI 3.0 supercharged V6 is faster than the RX 350L 3.5 DOHC V6:

Fuel Economy and Range

On the EPA test cycle the Q7 45 TFSI 4 cyl. gets better city fuel mileage than the RX 350L AWD (19 city/25 hwy vs. 18 city/25 hwy).

Regardless of its engine, the Q7’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) Lexus only offers an automatic engine start/stop system on the RXL Hybrid.

To lower fuel costs and make buying fuel easier, the Audi Q7 uses regular unleaded gasoline (premium recommended for maximum performance). The RX 450hL requires premium, which can cost 20 to 55 cents more per gallon.

The Q7 has 5.3 gallons more fuel capacity than the RXL Hybrid’s standard fuel tank (22.5 vs. 17.2 gallons), for longer range between fill-ups. The Q7 has 3.3 gallons more fuel capacity than the RXL’s standard fuel tank (22.5 vs. 19.2 gallons).

Consumer Reports

Tires and Wheels

For better traction, the Q7 has larger standard tires than the RXL (255/55R19 vs. 235/65R18). The Q7’s optional tires are larger than the largest tires available on the RXL (285/45R20 vs. 235/65R18).

The Q7 2.0T’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the RXL’s standard 65 series tires. The Q7’s optional tires have a lower 40 series profile than the RXL’s optional 55 series tires.

For better ride, handling and brake cooling the Q7 offers optional 21-inch wheels. The RXL’s largest wheels are only 20-inches.

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 RXL doesn’t offer run-flat tires.

Suspension and Handling

For a smoother ride and more stable handling, the Q7’s wheelbase is 8.1 inches longer than on the RXL (117.9 inches vs. 109.8 inches).

For better handling and stability, the track (width between the wheels) on the Q7 is 1.7 inches wider in the front and 2.6 inches wider in the rear than on the RXL.

The Q7 Prestige handles at .85 G’s, while the RX 350L AWD pulls only .75 G’s of cornering force in a Motor Trend skidpad test.

The Q7 Premium Plus executes Motor Trend’s “Figure Eight” maneuver 2.1 seconds quicker than the RX 350L (26.4 seconds @ .68 average G’s vs. 28.5 seconds @ .6 average G’s).

For greater off-road capability the Q7 has a greater minimum ground clearance than the RXL (8.3 vs. 8.2 inches), allowing the Q7 to travel over rougher terrain without being stopped or damaged. The Q7 w/Air Suspension’s minimum ground clearance is 1.5 inches higher than on the RXL (9.7 vs. 8.2 inches).

Passenger Space

The Q7 has .3 inches more front legroom, 1.2 inches more front shoulder room, .3 inches more rear headroom, 7.9 inches more rear legroom, .7 inches more rear shoulder room, 1.1 inches more third row headroom, 5.7 inches more third row legroom and 3.7 inches more third row shoulder room than the RXL.

Cargo Capacity

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

Towing

The Q7’s standard towing capacity is much higher than the RXL’s (4400 vs. 0 pounds). Maximum trailer towing in the Lexus RXL is only 3500 pounds. The Q7 offers up to a 7700 lbs. towing capacity.

Servicing Ease

The engine in the Q7 is mounted longitudinally (North-South), instead of sideways, as in the RXL. This makes it easier to service and maintain, because there are no rear spark plugs and the accessory belts are in front.

Ergonomics

Unlike the driver-only memory system in the RXL, the Q7 Prestige offers an optional passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat, steering wheel position and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

To better shield the driver and front passenger’s vision, the Q7 has standard dual-element sun visors that can block glare from two directions simultaneously. The RXL doesn’t offer secondary sun visors.

A manual rear sunshade is optional in the Q7 to help block heat and glare for the rear passengers. The RXL doesn’t offer a rear sunshade.

Economic Advantages

According to The Car Book by Jack Gillis, the Q7 is less expensive to operate than the RXL because typical repairs cost much less on the Q7 than the RXL, including $737 less for a water pump, $578 less for a timing belt/chain and $1538 less for a power steering pump.

Recommendations

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

The Q7 was chosen as one of Car and Driver’s “Top Five/10Best Trucks” for 2 of the last 2 years. The RXL has never been a Car and Driver “Top Five/10Best Truck” pick.
